ROTARY MATRIX HEAD TO CUT OR DRILL LABELS, AND METHOD FOR FORMING A CUTTING LABEL IN A COAT.

BACKGROUND OF THE INVENTION

Field of the Invention [001] The present invention relates to the field of labels that are provided with linings or without separating linings between the labels. The invention also concerns a method of using light weight coatings in label application processes to reduce operating costs. The present invention also concerns apparatus and methods for applying regular label backings and uncoated labels to substrates. The present invention also relates to the use of label backing microperforations (micro-bridges) or complete cutting of labels from a die prior to laminating with coatings. The present invention also relates to the use of a labeling apparatus that can withstand cutting labels with or without the use of vacuum systems. The present technology also concerns an exclusive die cutting tool for label application that takes into account high speed die cutting of exposed adhesive label substrates where the die cutting edge actually comes into contact with the adhesive. Background to the Technique [002] Labels can be provided in many different formats. The most significant format of labels is a label material (often referred to as a backrest, for example, natural or synthetic fiber paper, polymer film, thin metal foil, or combinations of these materials) with an adhesive on the back ( for example, pressure sensitive adhesive, which for some uses may also include repositionable or microspherical adhesive, solvent activated adhesive and thermally activated adhesive), and a coating 870180036999, from 05/04/2018, p. 6/87

2/71 release device in contact with the adhesive. The labels are formed from the label backrest in which the shape of the labels is cut into the label material, leaving a remainder of the label material called an array. The process of cutting the label forms from the label material (and sometimes including removing the matrix, leaving a label on a liner, and / or separating multiple width labels on a screen into single width label screens) is called conversion.

[003] Labels that are not supplied for trade (for intermediate users or end users) with coatings on an adhesive face, referred to in the art as uncoated labels, are cheaper than coated labels, more labels can be supplied on a roll of a given diameter than conventional labels with release liners, and they are more environmentally friendly since they do not require the disposal of linings after use. (For example, any backing with an adhesive layer that is provided in the form of an uncoated roll between an adhesive surface and the display surface of a label is an example of an uncoated label). Uncoated labels should also be cheaper since a total element (the coating) can be removed from the cost of making the label. Coatings can make up 35% to 50% of the total cost of a coated label construction. For these and other reasons, uncoated labels are achieving increasing popularity. Equipment for applying uncoated label with adhesives that can be rewet or thermally sensitive to a wide variety of moving elements (such as substrates, bottles, or packages) is fairly common, as shown in US patents 2,492,908 and 4,468,274 . However, the application of pressure sensitive adhesive labels uncoated to moving elements, although known in

Petition 870180036999, of 05/04/2018, p. 7/87

3/71 technical, is unusual (for example, US patent 4,978,415), and lacks the versatility to apply labels to all types of moving elements, such as envelopes, canvas, bottles, cans and packages.

[004] According to US patent 5,674,345, a method and apparatus are provided that quickly, positively, and in a versatile manner apply pressure sensitive adhesive labels without coating to moving elements. The equipment and method are versatile since they can be used with envelopes, packages, substrates, bottles, cans and with a wide variety of other moving elements, and the method and apparatus are typically practiced in order not to leave skeletal canvas after the labels are formed, thus avoiding any need to dispose of any waste label material. According to the apparatus of this invention, a device for mounting a supply of uncoated label tape having a release coated face and an adhesive face (typically pressure sensitive adhesive) is associated with several novel apparatus elements according to the invention. These unprecedented elements include a non-sticking circumferential feed roller, a hardened vacuum support cylinder cooperating with a cutting cylinder having a knife blade extending radially, which in turn cooperates with a cleaning roller that applies liquid release to the blade after each cut, and transport device having many unique features. The conveying device includes a plurality of conveyor belts that are spaced in a direction transverse to the conveying direction of the labels attached thereto, and a vacuum chamber helps the label adhesive to hold the labels in position on the conveyor belts during transportation . The typical conveyor belts are substantially circular in cross section in order to present a minimum area for fitting with the label adhesive, and the

Petition 870180036999, of 05/04/2018, p. 8/87

4/71 labels are separated from the conveyor belts by a plurality of non-stick surface extraction rings that extend upwardly above the upper surface of the conveyor belts, and which are associated with a peeling roller that folds the labels upward as they are deflected by the extraction rings. From the peeling roller and extraction rings, the labels are moved directly to contact a moving element. Where, as typical, labels are moved to contact moving envelopes, labels and envelopes pass through the press rollers through which the pressure sensitive adhesive is activated.

[005] Uncoated labels have also become increasingly popular because of the many advantages associated with them. When any labels (including uncoated labels) are used, it is also necessary to be able to automatically print the labels in a low cost manner. One way this can be readily accomplished when using a thermal printer, a thermal printer having a thermal print head with a thermal ribbon wrap and unwind system, or a thermal printer with a direct thermal print head. Conventional thermal printers are not able to print uncoated labels, however, because there will be surfaces on them that necessarily come into contact with the exposed adhesive face of the uncoated labels as the labels are being fed into the print head during printing, or later. According to US patent 5,560,293, a variety of thermal printers are provided that overcome this problem and are eminently suitable for effective printing of uncoated labels. Uncoated labels printed in accordance with the present invention can be almost all types of uncoated labels, such as, for example, thermal tape modalities

Petition 870180036999, of 05/04/2018, p. 9/87

5/71 shown in US patent 5,354,588 and direct thermal printer embodiments as shown in US patent 5,292,713.

[006] US patent 5,560,293 describes a thermal printer that prints uncoated labels in such a way that printer components will not stick to the adhesive face of uncoated labels. Substantially stationary printer components, such as a label guide, transport plate, front panel, and extractor blade, preferably have the adhesive-faced insert surfaces coated with plasma so that adhesive will not stick to them. An optional cutter supplied downstream of the extractor blade also has plasma-coated surfaces. A driven print cylinder has a surface that is coated or covered with a high-release silicone, which will not stick to the adhesive, but has high friction characteristics to facilitate label pushing. In a direct thermal printer, a plasma-coated cutting surface is downstream of the driven print cylinder, and extractor belts, a second roll with 0-rings and more are provided to prevent labels from wrapping around the print cylinder. triggered. One or more sensors can also be provided to control the activation of the printing cylinder in response to the position of the registration marks on the uncoated labels. According to one aspect of this invention a thermal printer for printing uncoated labels, having an uncoated adhesive face, is provided comprising the following elements: an uncoated label unwinder; a substantially stationary label guide; a substantially stationary transport plate; a rotatable driven impression cylinder; a print head cooperating with the print cylinder; and the label guide and the transport plate having surfaces that fit the adhesive face of uncoated labels from DePetition 870180036999, of 05/04/2018, pg. 10/87

6/71 label seam, the adhesive engaging surfaces comprising plasma coated surfaces that substantially prevent the label adhesive from sticking to them. The print head preferably comprises a thermal print head, and a thermal printer unwinding and rewinding system is associated with the print head that supplies the thermal tape between the print head and the driven print cylinder. The driven print cylinder preferably has a peripheral surface of the same which is coated with a high-release silicone which has both non-sticking characteristics with respect to the adhesive face of uncoated labels and high friction characteristics to facilitate label pushing. Any other substantially stationary surfaces of the printer that are also likely to come into contact with the adhesive face of uncoated labels, such as a front panel, are also coated with plasma. The shipping plate can be grooved to minimize the surface area that fits the label adhesive face. The printer also preferably comprises an extractor blade / bridge mounted on the opposite side of the printing cylinder driven from the label unwinder, in the direction of transport of the label through the printer. The extractor blade / bridge is positioned with respect to the driven print cylinder and the print head to prevent a printed label from being wrapped around the driven print cylinder and to help the label move from the print cylinder to the cutter. The extractor blade / bridge has a non-stick surface, preferably a plasma coating, and typically the extractor blade / bridge can be mounted directly on a pre-existing cutter bar on the printer. According to this invention a conventional thermal printer can be readily modified by simply replacing the non-label guide

Petition 870180036999, of 05/04/2018, p. 11/87

7/71 fastener, transport plate and the activated impression cylinder in accordance with the invention, and mount the extractor blade / bridge on the existing cutting bar.

[007] Uncoated labels are produced, for example, by feeding a tape having a release coated face and an adhesive face for a hardened support vacuum cylinder using a non-sticking circumferential surface feed roller. A knife blade on a cutting cylinder is rotated to contact the tape on the backing cylinder to cut the tape on uncoated labels, and release liquid is applied to the blade after each cut. From the support cylinder, the labels are deposited on a plurality of conveyor belts spaced in a circular cross section with the adhesive faces coming into contact with the conveyor belts. A vacuum chamber helps to retain the labels on the conveyor belts. The coating release faces of labels carried by the conveyor belts can be heated and then printed with hot fusion ink from an inkjet printer. The labels are separated from the conveyor belts using a peeling roller and non-stick extractor rings, and then immediately come into contact with a moving screen or other elements to which they must be applied, with the label and the screen passing through the press rollers. to activate the pressure sensitive adhesive.

[008] Despite the benefits that are obvious from the proposed and actual use of uncoated labels, the growth of technology has not been as fast in trade as has been expected. The low acceptance rate is because, at least in part, the present capacity of the application equipment is significantly lower than for coated labels. In production and supply, higher rates without waste are critical for efficiency levels. Petition 870180036999, 05/04/2018, p. 12/87

8/71 cia, productivity and profitability. Significantly slower equipment, such as the uncoated label application systems that operate at speeds of a quarter to half the speed of coated label applicators, reduces the competitive cost aspects of the uncoated label. In addition, the specific equipment cost for uncoated labels requires an independent capital investment for equipment that is useful only for uncoated labels. For a manufacturer to convert from a coated label process or to add to a coated label process in his business, a completely new device has to be purchased. At a cost of hundreds of thousands of dollars, this is not a highly attractive scenario for labeling companies.

[009] According to the invention described in US patent 6,206,071, a method and apparatus are provided that quickly, positively and in a versatile manner apply pressure sensitive adhesive labels without coating to moving elements. The equipment and method are versatile since they can be used with any substrate, including, for example, envelopes, packages, bottles, cans, and with a wide variety of other moving elements, they can be used with any available uncoated label, and the method can be used in an existing commercial apparatus by adding an inventive module in accordance with the practice of this present invention. The process of this present invention comprises associating the uncoated label with a temporary reusable support (temporary reusable coating) in line or just before introduction into the label application apparatus, removing the label from the reusable temporary support, rolling up the temporary support, and reusing the temporary support again to support an uncoated label for insertion into commercial coated label applicators

9/71 with withdrawal capacity.

[0010] US patent 6,187,128 describes a method and apparatus for converting and applying labels. The apparatus includes a vacuum support roller and a guide roller that cooperate to separate the base backrest (the label material and the liner) into its component parts (the label material or face fabric and the back layer liner) ). A cutting roller cooperates with the vacuum support roller for cutting the end of the uncoated face of the face screen to form end cutting labels. A traction press roller cooperates with the vacuum backing roller to press the end cut labels to the rear layer coating to form labels that can be released. The benefit of the process is assured to overcome a problem with backing cutting processes by weakening or cutting the backing coating during conversion to labels with a releaseable coating.

[0011] Published US patent application 20010035257 (Fuji) describes a method of a standard embossing process having steps of transferring an embossing pattern to a thermoplastic resin sheet when using an embossing modeling roller ; shine the opposite face of the embossed face of the thermoplastic resin sheet by using a shine device having a mirror face element; and peeling the thermoplastic resin sheet from the embossing modeling roll at a lower temperature than a temperature to transfer the embossing pattern. The embossing modeling roller has a roller body, having a face embossed with the pattern, and sealing rings attached to each side face of the roller body, where the roller body and the sealing ring have a passage to flow a seal ring cooling medium through the

Petition 870180036999, of 05/04/2018, p. 14/87

10/71 roller body for the other seal ring. The roller body 17, in turn, is composed of an outer cylinder section 19; a center cylinder section 21 inserted inside the outer cylinder section 19; and an inner cylinder section 22 inserted inside the center cylinder section 21. Incidentally, in the processing apparatus 10, from the embossing modeling roll 13 on the opposite side of the roll 14, a cooling roll 44 can be placed to rest on the outer circumferential surface of the elastic roller 14. The temperature of the surface of the elastic roller 14 can be controlled by the cooling roller 44.

[0012] US patent 4,400,230 (Wyslotsky) discloses a labeling and indexing apparatus in which a substrate backrest storage axis 50 is provided to rotatively support and disengage the substrate backing 52 from a roll 54 of the same. In connection with this, the directional substrate stop rollers 56, 58, 60, 62, 63, 64, 64 are carried by the frame 22 to direct the substrate stop 52 in the first direction, as indicated by arrow A, for eventual arrangement inside and fitting able to pass through the thermal narrowing 46 and in contact in the thermal narrowing 46 with the label backing 29, as shown in figure 7. In this way, the label backing 29 and the substrate 52 are joined together in the thermal narrowing 46 to form a laminate 66 as shown in figures 1 and 7. Upstream of the thermal narrowing 46 a cooling roller 72 is provided having the parts of the affluent and effluent of cooling liquid water 72a, 72b, and with the coolant outlet guide roller disposed laterally for monitoring 73, cooling the sticky backboard laminate and attached substrate 66.

11/71 known, as disclosed in US patent 7,070,727 (Calhoun et al.) And 6,743,469 (DiZio).

[0014] US patent 6,652,172 (Wood et al.) Actually discloses the use of heating die cut rolls in an uncoated label process. A method of cutting a label segment from an uncoated ribbon web within a printing device for subsequent application to an article is claimed, the uncoated ribbon web being defined by a printing side and an adhesive side, the method comprising: providing a cutting device including a heated cutting element; directing the uncoated ribbon web to the heated cutting element with a delivery device in such a way that the printing side is close to the heated cutting element; placing the uncoated ribbon web in contact with the heated cutting element to separate the label segment from the rest of the web as part of a cutting operation; and raising the temperature of the heated cutting element to at least a temperature of 1600 degrees Fahrenheit (871.11 degrees Celsius) to clean the heated cutting element following the cutting operation.

SUMMARY OF THE INVENTION [0015] The present invention provides an alternative method of converting label backing (a label and coating face fabric) or uncoated label backing (which can then be combined with conventional coating). The label application apparatus (both at the points of applying labels to coatings and at the downstream locations where labels are applied to commercial articles) can use lighter (thinner) coating and therefore cheaper than can be used with conventional conversion and labeling processes. Label screen face (including uncoated label screens) can be cut (the term “cut”, unless it limitsPetition 870180036999, 05/04/2018, page 16/87

12/71 of the otherwise, is defined as including either a full through cut, micron bridge cut as defined in this document, or perforated cut that includes all intermediate cuts to a micron bridge cut and full through cut with no bridges between the label and the matrix) and then applied to a coating, the adhesive face of the label web face positioned against a coating release surface. Cutting label is applied to the liner back (which may include a temporary reusable liner support) before the cut label back is applied by means of a coated label application apparatus or coated label application step. In this way, the roll of coated backing material (or coated) or uncoated backing material (in a removable temporary coating) can be supplied to the final customer of the printing installation without the final customer having to be involved even with the addition of supplementary apparatus such as the component described in US patent 6,206,071. The device on site with the end customer may not have to be modified in any way from the conventional device used to apply conventional backing label backing. A preferred system includes an unprecedented device that converts and applies labels to coatings and at the end device that removes coating labels and applies the labels to articles of commerce.

[0016] An exclusive element of an apparatus and process according to an embodiment of the invention is the use of a roll to attach a conductive edge of a label while it is being cut or while it is still supported on a support roll / Support. Fixing the conductive edge (which is the leading edge in the direction of movement of the label) provides several effects on the label and the line that have not been noticed, especially where the label is cut without a coating being present in

Petition 870180036999, of 05/04/2018, p. 17/87

13/71 contact with an adhesive face of the label material.

[0017] According to the invention, uncoated label backing can be applied to a temporary charger (optionally reusable) with pre-cut label forms and then combined with a coating, including a thin coating. The structure segments of the cut labels are removed before, during or after applying the label back to the temporary loader. The printing of the labels can be done during the manufacture of the label backrest, after the manufacture of the material or label backrest, before the cut of the label material backrest, after the cutting of the material or label backrest, before the application of the material label or label backing to the temporary support or after applying the label material or label backing to the reusable temporary support. [0018] An additional process and apparatus for the practice of the present invention comprises a device for reducing the amount of work that has to be performed on a single line, separating the work on different lines and even at different locations that can reduce contamination problems cross-checking of materials used in different segments of the global process. In particular, the invention takes into account printing on sheets that are cut in materials that form label rolls or printing on the material and directly wrapping the printed sheets. Then, on a separate line (separate from the printing line), adhesive (any form of adhesive, by way of non-limiting examples, solvent activated adhesive, pressure sensitive adhesive, repositionable adhesive, fusion adhesive, energy activated adhesive and others more) is applied to the side of the sheet away from printing (or to the printed side if the label is to be applied with the printed surface down), preferably, but not necessarily before cutting into the roll width of the printed sheet. Another surprising aspect of the invention is that a coating

Petition 870180036999, of 05/04/2018, p. 18/87

14/71 fine can be supplied for the label material after cutting the label material, enabling the use of thin-coated screens on a coated label, without the consequent waste or lack of quality that would be expected from the use of thin coatings. Because of the generally thin coating layer, the operation of cutting or converting a label to a thin coating can be expected to separate or curl the layers. The label material (sheet, roll or canvas), preferably printed, with adhesive is cut (for example, die cut) in the desired shape for the label, the cut label moved through the apparatus with application in a loader or coating for form a fully assembled label supply screen with a removable charger. The die is removed from the fully assembled label supply screen before rewinding onto a roll is completed. Matrix removal can occur before (or after [preferred]) laminating the label material to the magazine. It is unprecedented, according to the present invention, to form the roll in order to print on the sheet, apply the adhesive, cut the labels and then apply the labels on the reusable temporary magazine.

[0019] The use of a cooled cutting die (impact die cutting implement) is the edge for adhesive or edge for the back side or a carrier with adhesive has been discovered to reduce adhesive collection within the system, reduce transfer of adhesive from one component to another, and reduce downtime for the apparatus required for removing adhesive from label sticking.

[0020] A preferred embodiment of this die cutting method is to use the cutting tool to cut a label substrate that has an exposed adhesive surface for the cutting tool and to cool the cutting tool to a temperature that is below the temperature of glass transition of the exposed adhesive. The temperature of

Petition 870180036999, of 05/04/2018, p. 19/87

15/71 glass transition of an adhesive (Tg) is a recognized technique characteristic of an adhesive and represents at what temperature it changes from a soft material that flows to a brittle and hard material similar to glass. An exclusive characteristic of an adhesive is that at this temperature Tg, or below it, it loses a lot or completely loses its adhesive characteristics. When attempting to rotate the die cutting material where the exposed adhesive is necessarily in contact with the cutting tool ruler, it is desirable to reduce the adhesion between the adhesive and the die, which reduces preparation in the die. In this preferred embodiment, the cut or partially cut label material is less likely to stick to the cutting tool. This unique cooling technique eliminates this problem.

[0021] One aspect of the technology is to cool the die to a temperature and condition such that the adhesive will not stick to the die body or ruler or die cutting edge.

DETAILED DESCRIPTION OF THE INVENTION [0029] The invention relates to the use of labels on lining material, and can include and use any label material, whether on paper bases (both natural fiber paper and artificial fiber paper and a mixture of them) ), polymeric film, thin metal foil and combinations of these materials. Much of the practice of the invention will be described with respect to the uncoated label, so that the label material provided a starting point for the practice of the invention and was the most complex material to work with. The emphasis is that the particular label material is not intended to diminish the broader scope of the invention in any way, and the term should be seen as exemplary rather than limiting. The steps described for use with uncoated labels can be used with other conventional label materials. The only difference would probably be that conventional label material can be fed in the cutting step from a coated roll or full label back, the label material removed or delaminated from the coating, the cutting of label material, and then the reapplied or re-laminated label on the liner. Although US patent 6,187,128 attempted to perform a delamination / re-laminating process using perforated label vacuum support, it is believed that the use of vacuum support creates difficulties, it is believed that the process is not accepted as true to be commercialized and that the use of vacuum would not only fail to facilitate the use of thin-coated screens, but also it will be repeated 870180036999, of 05/04/2018, p. 21/87

17/71 would seriously deteriorate the final product with a thin-coated canvas because of the wrinkle tension applied to the thin-faced layer and the combined label backrest.

[0030] A component that is used in the practice of the present invention comprises a die head for cutting or perforating labels comprising adhesive on label backing, comprising a die head having at least 80% of its outer surface comprising flat areas between edges of cutting, multiple cutting edges on the outer surface and an internal volume on the matrix head, the internal volume to transport cooling liquid in and out of the volume in order to cool the external surface of the matrix head when the cooling temperature is at least 10 ° colder than the outer surface of the die head. The die head can have coolant that passes into the inner volume of the die head, passes through a cutting zone on the die head and reverse flow direction of the coolant to exit the die head or have liquid cooling fluid that passes into the internal volume of the matrix head, passes through a cutting zone in the matrix head and the cooling liquid continues in a flow direction to exit the matrix head. The die head can have a distance between a closer flow point between the coolant in the internal volume and the external surface between 2 and 50 mm, preferably between 2 mm and 10 mm.

[0031] A die head for cutting or perforating labels according to an embodiment of the invention can comprise cutting adhesive on label backing. The die head of a preferred embodiment may comprise an outer surface comprising flat areas and raised cutting edges above the flat areas. The matrix head has:

Petition 870180036999, of 05/04/2018, p. 22/87

18/71 at least 80% of its external surface comprising the flat areas between the raised cutting edges;

multiple cutting edges raised on the outer surface; and an internal volume in the matrix head.

[0032] The preferred matrix head can be characterized by the internal volume in the matrix head enabling the transport of cooling liquid in and out of the volume, in order to cool the external surface of the matrix head when the cooling temperature is at minus 10Ό cooler than the outer surface of the matrix head. The coolant passes into the inner volume of the die head in a flow direction (for example, in a general direction from one side of the cutting head to the other), passes through a cutting zone on the matrix head , and reverses the flow direction of the coolant to exit the die head (generally back to the side). Alternatively in the matrix head, the cooling liquid passes into the internal volume of the matrix head, from a first side of the matrix head, through a cutting zone in the matrix head and the cooling liquid continues in one direction flow to exit the die head on one side of the die head opposite the first side. The die head preferably has at least 90% of its outer surface comprising flat areas between cutting edges and the die head cooling is for a temperature below 15Ό or below a Tg of the adhesive on the label backing, no matter what. smaller.

[0033] A method for forming a cut label on a liner using the die head can comprise feeding a web of label material to a cutting station comprising the cooling die head described in this document and forming

Petition 870180036999, of 05/04/2018, p. 23/87

19/71 a cut label material having an adhesive face on the cut label material; cutting the label material to provide a matrix adjacent to a leading edge of the cutting label and a trailing edge of the cutting label, the distance between the leading edge and the trailing edge defining a length for the cutting label; cool the matrix head by passing coolant through the internal volume of the matrix head; stabilize the leading edge of the label material with respect to the matrix adjacent the leading edge before the trailing edge of the label material leaves the cutting station, stabilization being carried out without vacuum being distributed over an area comprising at least 50% of the cutting label surface; feeding the leading edge of the label material and the matrix adjacent the leading edge of the label material into a narrowing formed between a set of rollers, while the trailing edge of the label is stabilized without vacuum; feed a liner into the set of rollers against the adhesive face. Conductive edge stabilization can be performed without any vacuum being applied to the cut label material. The stabilizing force can be applied by means of a physical element by pressing the conductive edge against a surface of a roller. The cutting station may comprise a support roll and cutter die with said die head or an impact roll and impact cutter die with said die head. The method can be practiced with stabilization of the conductive edge executed with or without any vacuum being applied to the cut label material. For example, the method can stabilize the conductive edge with a vacuum by being applied to the cutting label material after being cut by the die head.

[0035] A description of the present invention would include that of a method for forming a cut label on a liner, comprising: feeding a web of label material to a cutting station and forming a cut label material having a surface area on a non-adhesive face of the cut label material; cutting the label material to provide a matrix adjacent to a leading edge of the cutting label and a trailing edge of the cutting label, the distance between the leading edge and the trailing edge defining a length for the cutting label; stabilize the leading edge of the label material with respect to the matrix adjacent to the leading edge before the trailing edge of the label material leaves the cutting station, stabilization being carried out without vacuum being applied across an area comprising at least 50% of the area of surface; feeding the leading edge of the label material and the matrix adjacent the leading edge of the label material into a narrowing formed between a set of rollers; feed a liner to the roller set.

[0036] Stabilization can be performed in several ways, without having to use vacuum on significant surfaces of the surface area. Petition 870180036999, from 05/04/2018, pg. 25/87

21/71 label type. The application of vacuum over a significantly large surface area has in itself been a significant reason for the failure of prior art systems. The vacuum can deform the coating material (even reasonably permanently, when notching). The cost of vacuum support rollers is very high, and vacuum support rollers often have to be replaced for each label size that is to be cut to ensure that the vacuum seal according to each label size is safe. . The use of different vacuum support rollers also increases equipment downtime during service changes. It is possible to have a vacuum centerline on the support roll, or a distribution of holes along the lines on the support that would cover small central areas of individual labels to stabilize them. For example, if there are 2, 3, 4, 5 or 6 labels to be prepared across a support width, there will be support rollers provided with 2, 3, 4, 5 or 6 rows of holes (respectively) distributed over the width of the support roll (for example, the lines being parallel to the surface movement of the support roll), so that the labels can be applied on the support surface only with small or minimal areas of vacuum applied to the labels and where even vacuum reduced can be applied (for example, less than 10 cm Hg, less than 5 cm Hg and others more). It is preferred that vacuum is not applied, but reduced amounts of vacuum in combination with the other stabilization systems described in this document can be used.

[0037] This redistribution of vacuum holes would effectively require that, for some label sizes, the surface area of the label over which the vacuum holes are distributed was less than 50% of that label surface area, less than 40% of the surface area, less than 30% of the surface area, less than 20% of the surface area, less than 20% of the surface area, less than 10%

Petition 870180036999, of 05/04/2018, p. 26/87

22/71 of the surface area, or even form a single line below the middle of the label. It is to be understood that these percentages of surface areas are the areas between the most distal holes affecting the labels. For example, if the holes were located halfway between a centerline on the label and its edges, the area covered by the vacuum would be 50% of the label area. If the holes were located 10% of the distance from the centerline to the edges, then 20% of the label area would be covered by the vacuum. It is preferred that vacuum is not applied to the label during stabilization of the label during cutting and then transferring to the coating, as described in the practice of this invention.

[0038] The stabilization function is intended to stabilize at least against relative movement between cutting label material and the matrix formed by cutting the label material. This can be done using different methods and even different structures in the label material. Where the label stop is a separating cut (ie, 100% of the label edge is completely cut and separated from the matrix), the stabilization function or procedure is the only factor stabilizing against this relative movement. Among the different methodologies that can be used to provide this function are, but are not limited to, perforation cutting, microdump cutting (preferred), electrostatic charge of layers or surfaces to retain contact, pneumatic forces, surface tensile forces and, more preferred, physical forces firmly retaining both the cutting label edge and the matrix edge relative to each other. A combination of the use of physical force (particularly when provided by the press rollers or by means of a narrowing between rollers) and micro-bridges is also highly preferred. A preferred method includes stabilizing at least the leading edge, where stabilization is performed without any vacuum being applied to the label material. THE

Petition 870180036999, of 05/04/2018, p. 27/87

23/71 stabilizing force can be applied by means of a physical element by pressing the conductive edge against a surface of a roller. The physical element is preferably a roller. The roll may be a separate pair of press rollers or may be a single roll forming a nip on the surface of the support roll. These alternatives will be shown in more detail in a discussion of the figures. [0039] The cutting of the label material can be carried out with any cutting device, although some are known in the art for being more suitable or desirable than others. For example, cutting can be performed by means of a laser cutter, a support roll and cutter die, air jet cutter, a water jet cutter, a support roll and impact cutter die and others more.

[0040] The method of stabilizing with rollers can be practiced by identifying a distance between a location on the support roll where the trailing edge is cut and a stabilizing narrowing to stabilize relative movement between the cut label and the die, and ensure that this distance is approximately equal to or less than the length of the label. The label material can be supplied by coating the label material.

[0041] These methods enable the use of ultrathin or ultralight coatings. This ability has never been possible before in the art. This can create significant savings for the industry, as the cost of many sheet materials is dependent primarily on the amount of material used. In particular, avoiding vacuum clamping should be practiced where materials are thinner and lighter, since thinner and lighter materials can be more readily deformed than thicker and heavier materials would be. The values of these thicknesses and weights of these lightweight materials are discussed more fully elsewhere in the text. Thickness

24/71 favorites, however, are less than 1.02 thousand, less than 0.93 thousand, less than 0.75 thousand, less than 0.65 thousand, less than 0.50 thousand, and equal to or less than 0, 30 thousand or 0.25 thousand coating thickness (respectively less than 0.026 mm, 0.023 mm, 0.0186 mm, 0.016 mm, 0.013 mm, 0.0078 mm or 0.0064 mm), particularly polymeric coating and, more particularly , polyester coating (eg polyethylene terephthalate film or polyethylene naphthalate).

[0042] One embodiment of a method for forming a cut label on a coating according to the invention can also be described as first comprising feeding a web of label material to a cutting station forming a first narrowing between a support roll and a die cutting roll. The label material is then cut (perforated, micro-cut or separator cut) to provide a leading edge of the cutting label and a trailing edge of the cutting label, the distance between the leading edge and the trailing edge defining a length for the label cutting. The cutting label is fed to a second nip formed by the rollers, and a liner is fed into the second nip formed by the rollers. Where the press rollers are stabilizing movement between the cutting label and the die, the distance between the first nip and the second nip should be approximately equal to or less than the length of the label. The method can be practiced where the second nip is formed between the support roll and a stabilization roll, and preferably where a vacuum is not used to support the cut label on the support roll.

[0043] The practice of the present invention enables separating the coating from the label material, cutting the label material, and re-rolling the cutting label material to the coating or to new.

Petition 870180036999, of 05/04/2018, p. 29/87

25/71 coating, without the use of vacuum. The original label can also be cut and fed into the original backing or reusable. Where a micro-point cut is used on the label, the cut may comprise a cut in which less than 5.0% (even less than 4.0%, less than 3.0%, less than 1.0%, less than 0 , 5%, and even less than 0.2%) of the total edge retains material that extends over the label and its matrix, and not a single bridge element comprises more than 2% or more than 1.0% of the distance linear edge (preferably less than 0.30%, less than 0.20%, less than 0.10%, and even less than 0.05%). The total coating length of the entire cut forming the label is preferably less than 2%, preferably less than 1.5% and even less than 1% of the total cut length, with not a single cut (for example, between 4 to 100 microperforations) being no more than 0.5%, preferably less than 0.5%, and more preferably less than 0.25% of the total length of the wrapping cut line that forms the cut.

[0044] An embodiment of the invention may include applying labels to a substrate in which, after forming the label backing according to the method of claim 1, individual micro-label labels are removed from the coating, leaving a matrix of label on the liner, and the individual labels being applied to a substrate, or where, after forming the label backing, the micro-bridged label matrix is removed from the liner, leaving cut labels of label material on the liner, and the individual labels are subsequently applied to a substrate. This can be used to form a source of labels comprising a compound of an elongated temporary coating sheet with a thickness of 0.0259 mm or 1.02 mils or less and having adhered to a low adhesion surface of said coating

26/71 temporary an adhesive face of the label material, said compound being on a roll. The label source can be with the label material being cut label material, including separator cut label material, micro-point cut and perforated cut.

[0045] Coatings other than polymeric coatings can also benefit from the practice of the present invention, and the reduced cost and increased performance of coatings (for example, permanent and temporary, reusable and disposable coatings) can be described alternatively or further. most appropriate by means of parameters other than thickness. For example, release-coated or fiber-based coatings can be characterized in terms of weight per square meter. For example, high quality standard silicone paper liner (which can still be used in the practice of the invention) is commercially available in standard properties of around 60 g / m ² (around 53 micros or 2.1 mil) . The benefits of the invention enable the optional use of lighter weight silicone paper (or other super-calendered papers, with or without absorbed or coated release materials or other treatment materials) with weights of 55 g / m ² or less, 50 g / m ² or less, 45 g / m ² or less or even 40 or 30 g / m ² or less. These supercalendered papers of less weight would have thicknesses more in the order of less than 2.0 mils (0.051 mm), less than 1.7 mils (0.043 mm), less than 1.5 mils (0.038 mm) and even less than 1, 2 mils (0.031 mm).

[0046] Another form of release liner is commercially available and referred to as Super Calendered Kraft paper (SCK paper). This is usually supplied as stock of 40 pounds (88 kg / ream) around 2.5 mils (0.064 mm) per sheet thickness. The practice of the present invention would enable the use of a lighter and thinner coating, saving significant costs. Thickness

27/71 less than the standard 2.5 mils (less than 0.064 mm), less than 2.2 mils (0.060 mm), less than 2.0 mils (0.051 mm), less than 1.8 mils (0.042 mm), and even less than 1.2 mils (0.031 mm) would be useful in the practice of the present invention, while they are not to be usable safely in prior art label application processes.

[0047] Yet another coating format that can be used on machine finished papers (MF papers). Standard commercial weights are such as stock 50 pounds (110 kg) with a thickness of about 3.4 mils (0.09 mm) per sheet. The practice of the invention would enable the use of MF paper thickness of less than 3.4 mils (0.09 mm), less than 3.0 mils (0.077 mm), less than 2.6 mils (0.067 mm), less than 2.2 mils (0.060 mm), less than 2.0 mils (0.051 mm), and even less than 1.2 mils (0.031 mm).

[0048] Polymer coated papers, especially polyolefin coated papers (eg polypropylene and / or polyethylene) are also commercially available with stock weights of around 40 pounds (88 kg) and traditional thickness of about 2.5 mils (0.064 mm). Less than standard thickness of 2.5 mils (less than 0.064 mm), less than 2.2 mils (0.060 mm), less than 2.0 mils (0.051 mm), less than 1.8 mils (0.042 mm) , and even less than 1.2 mils (0.031 mm) would be useful in the practice of the present invention, while they are not to be usable safely in prior art label application processes.

[0049] Uncoated label tape conventionally has a label substrate, a release coated face and an adhesive coated face (typically pressure sensitive adhesive, although thermal and solvent-activated adhesives are known). Uncoated label is usually supplied in roll or stacked form, with the adhesive side of a sheet or roll

Petition 870180036999, of 05/04/2018, p. 32/87

28/71 in contact with the coated release face of another sheet or of the adjacent rolled layer. The label is cut, partially cut or pre-cut directly from the roll or sheet in the pile and applied to a substrate or element on which a label is to be applied. It is common in the art for the uncoated label to be cut by a matrix, especially a cylindrical matrix, before the label is sent to the article to which the label is to be applied. The primary purpose of the uncoated label over the more conventional coated label is to eliminate the necessary step of disposing of the coating after the label is applied. This disposal is inconvenient, increases the cost of the user, and usually increases the cost of the label material, since there is another layer of material that is present in any form of a coated label. Regular label backrest has been cut through the label and through the adhesive, with minimal effort to contact and not damage the lining. Moving label backing at rates above 50 m / s requires very precise equipment and little variation in materials to enable successful cutting and minimizing waste and damage due to insufficient cutting or excessive cutting of the coating. The method described in US patent 6,187,128 is an attempt to overcome these deficiencies, but because the necessary use of vacuum support of the label material and especially the cut label material has not proved satisfactory to the inventors and has not be known to have been marketed.

[0050] As noted earlier, however, the use of uncoated labels has been restricted by the need for additional capital expenditure as well as by the lack of efficiency in the performance of the device designed for applying uncoated labels. The present invention addresses and reduces these two problems as an alternative to the US patent apparatus, articles and methods

29/71

6,206,071 and 6,294,038, and the additional problems encountered with attempts to enforce US patent 6,187,128.

[0051] The present invention can be practiced in two ways. First, an apparatus can be constructed with the built-in ability to temporarily attach a laminated label or uncoated label to a reusable temporary support (preferably). Second, a module can be provided that can be attached to existing coated label applicator machines that enables these coated label applicators to apply coated labels made in accordance with the practice of the invention. Coated labels are applied to substrates or elements when feeding the coated coated backrest to an applicator. The applicator can be provided with die cut coated label backing or provide die cut inside the applicator itself. The label, after the die cut is pulled out of the coating by a tearing element (for example, blade, reduced pressure, scraper, flexor, peeler, bender or the like) and the patterned label (that is, a label shaped by the cut) matrix) is applied to the surface on which a label is desired. These systems for applying coated labels are readily available from several manufacturers and work very efficiently. The module of the present invention effectively creates a temporary coated uncoated label or normal coated label, removes the temporary coating and then preferably recycles the coating. By recycling the coating, which can be the same as or slightly modified from conventional coatings, the disposal of coatings is significantly reduced. When recycling a liner once, the material and disposal costs for the liner are reduced by 50%, and when recycling the liner in the expected twenty times or so, the cost of the liner is reduced by 95%. Even when recycling a rePetition 870180036999, from 05/04/2018, p. 34/87

30/71 clothing only three times, which can be readily done with conventional label coating materials, the cost savings in materials and disposal for the coating is 75%. As can be seen from cost efficiencies, only modest numbers of recycling need to be done to provide a significant economic advantage and significantly equivalent reductions in waste disposal costs. However, it is not essential for the practice of the present invention to recycle these coatings.

[0052] It is important to note that there are unique capabilities provided for the field of the invention and the commercial potential in the practice of the invention through the use of thin backing sheets. The practice of the invention also enables exclusively the manufacture of unique structures, which are not known to be enabled by any other process.

[0053] Firstly, the term "thin backing sheet" or "thin coating" has a defined meaning within the practice of the present invention. In usual practice, support sheets will normally be at least 1.50 mils (0.0015 inches or 0.038 mm). This is especially true where mechanical processing, such as rotating die backing of the label supported on the liner, is to be performed. This significant thickness is required because the cutting operation is neither precise nor tolerant of thin layers. Oscillation of layers and equipment, the essential need to ensure that the backrest is cut evenly and completely, wear of materials, wrinkles and folds and other physical variables cause the die cuts to vary significantly. The process is operated with tolerances ensuring that the die cut always goes completely through the backrest and the adhesive on the back side, and this means that it will almost always also penetrate the coating. To ensure that the coating is not cut

Petition 870180036999, of 05/04/2018, p. 35/87

31/71 entirely and therefore cause the sheet to fall into pieces as if there were no continuous structural layer, the coating should be thick enough (for example, at least about 0.038 mm) to ensure that the edge of die cuts the coating, but does not cut entirely through the coating. Therefore, a thin coating or thin backing sheet means a coating that is equal to or less than 1.02 mils (less than 0.0254 mm). Preferably, the coating is less than 1 mil (less than 0.0254 mm), more preferably less than 0.8 mil (0.0203 mm), less than 0.6 mil (less than 0.017 mm), and even as low as much as 0.25 thousand or less (0.00626 mm or less). A preferred range is less than 1.0 mil (less than 0.0254 mm), less than 0.9 mil (less than 0.023 mm), between 0.3 and 1.0 mil (0.0076 to 0.0254 mm ), 0.4 and 0.8 mils (approximately between 0.01 and 0.021 mm). Such thin support material is commercially available as Hostaphan® polyester film (a registered trademark of Hoecsht AG) (eg 0.5 mil, 0.0127 mm, silicone coated film of the trade name 2SLK), sheets from Mitsubishi Chemical Company, and is known to be used as a disposable coating on tar adhesive coatings. A related coating material is provided by Avery, Inc. as a 1.02 mil (0.026 mm) polyester backing sheet with a 1.25 mil (0.032 mm) adhesive layer.

[0054] Adhesives, like most polymers, have physical characteristics that can be measured and that are important for the use of the materials. An important property is the glass transition temperature of the polymer, which is a measure of certain types of phase or physical transitions or transformations that occur in polymers as they are heated and cooled. Since polymers do not necessarily pass from a solid phase to a liquid and a gaseous phase as some other materials do,

Petition 870180036999, of 05/04/2018, p. 36/87

32/71 equivalent transitions are measured, and the glass transition temperature, a temperature at which the average volume of a polymer changes from a solid, materials not able to flow, to a viscous one, but material capable of flowing is a transition temperature glassy. The glass transition temperature (Tg in the disclosure in this document) can be measured using Differential Scanning Calorimetry (DSC) using the procedure ASTM E-794-95. Analyzes can be conducted on a Pyris 1 instrument using the accompanying software available from Perkin Elmer Instruments, USA. All measurements were conducted during the first heating cycle between 100Ό and + 150Ό in a sample that was molded in 20 20 and allowed to harden at room temperature for approximately 7 days. The first heating cycle was developed at a temperature rise rate of 20'C / min. The heat of fusion is measured from the total area under the peak curve in the region of room temperature to 105Ό. The glass transition temperature is the central point interpolated from the inflection point in the DSC line corresponding to the greatest change in the thermal capacity of the sample. Where block copolymers or graft copolymers are used, they can have two different glass transition temperatures because of the different segments of the copolymers and the individual physical activity of the two blocks. In the practice of the present technology, where it is reported that cooling is to a temperature equal to or less than the glass transition temperature and a graft or block copolymer is used, the expression glass transition temperature can refer to one or the other of the two glass transition temperatures (the lowest Tg1 and the highest Tg2 temperature) and must refer at least to a temperature equal to or less than the Tg2 of the copolymer. In a preferred embodiment, it refers to the Tg1 of the copolymer.

[0055] The composition of the support sheet can be any type 870180036999, from 04/05/2018, p. 37/87

33/71 polymeric layer or even thin paper, such as polyester (for example, polyethylene terephthalate, polyethylene naphthalate), polyamide, polyvinyl resin, polyvinyl acetal resin, cellulosic resins (such as cellulose acetate, triacetate) cellulose, etc.), and artificial papers, especially translucent / transparent compacted paper layers of appropriate dimensions. Natural resins such as amylose resins can also be used. The surface of the layers can be treated physically or chemically to control their adhesion to the adhesive surface on the coating. Release layers, controlled release layers, and more such as silicone resins, acrylate resins, epoxy resins, and mixed resin functionalities can be used as extremely thin layers in the coating to control these properties such as crown discharge, spraying cathodic, oxidation, laser discharge, or chemical reaction of the surface.

[0056] There is a definite technical problem when trying to use a thin coating layer on label backing or uncoated label backing. This technical problem appears, at least in part, when trying to cut the label on the support. As noted earlier, the cut lacks the precision needed to cut consistently through the label without cutting through the coating. The coating is so thin that there is a regular occurrence of cutting through the coating when the coating is used at commercial label conversion speeds. Even when the die cutting speed is decreased in line to 25 feet (7.63 m) per minute, which is an extremely low manufacturing speed, there is probably still some through cut in the line. As normal manufacturing processes for labels are sought to be at least 100 feet (28.6 m) per minute, and preferably at least 150 feet / min (42.9 m / min), having to lower the process to one

Petition 870180036999, of 05/04/2018, p. 38/87

34/71 quarter of standard speeds is a significant cost disadvantage. The present process enables a process to be practiced that can manufacture thin-coated labels, and completely avoid any potential cutting through the coating. This is a significant technical advance. Even if the use of thin coating is tried in the vacuum process of US patent 6,187,128, the vacuum is capable of twisting or wrinkling the coating (for example, even if indirectly), slowing down the process and has been found to adversely affect the consistency and total continuity of the process.

[0057] Another technical problem that appears is because of the speed of manufacture that must be used to make the product more economical. As the speed increases, the likelihood of through-cut damage to normal label material increases significantly and the likelihood of thin-label distortion increases. Speed adds reduced alignment stability, reduced layer stability, less precision in die cutting, and the likelihood of production line downtime is increased to address deficiencies. The process of the present invention, by completely eliminating the possibility of through-cut damage, and by stabilizing both the cut label and the coating web enables the potential for increased speeds, even beyond those of standard manufacturing or label application systems.

[0058] The basic practices of the invention that enable these manufacturing improvements have advantages even beyond the application to thin coatings. One of these practices includes the use of ‘small perforation’, ‘micropicote’ or ‘microperforation’ of the label back before applying the cut label back to the liner. The use of a “label cutting stabilization bar” also enables the use of complete separation cutting label material in the process. 870180036999, from 05/04/2018, p. 39/87

35/71 before applying the coating screen to the cutting label material. The procedure referred to above as micropicotes is more accurately referred to as 'micropoints'. The use of microperforation or micro-bridging techniques (which will be described in more detail in this document) provides a label that has been sufficiently cut to the desired pattern for separation into individual labels without the need for additional treatment (for example, burr removal, cutting of finishing, etc.) and that also maintains the aesthetics required for a high quality label and does not require additional stabilization techniques between the die and the cutting label. At the same time, maintaining a pre-cut label sheet that can still be handled with a mechanical or manual system without difficulty is a significant advantage. Once a label backing sheet has been pre-cut to realize the shape of the labels, the labels would ordinarily (in previous processes) fall out of the die, sliding in relation to its alignment between the cutting label and the die, or they would have to be treated separately (such as by the process-damaging vacuum support). The ability to be able to prevent separation of the die cut label, slippage between the die and die cut label or removal of the die label before or at the same time or immediately after laminating the cut label to the coating is an advantage significant in itself, and can be a significant factor in enabling the use of thin coatings.

[0059] The term micropicote, micropon or microperforation as used in the practice of the present invention has a defined meaning in accordance with the present invention. When a label is ordinarily cut from the backing or label sheet, the entire periphery of the label design is cut, the label removed (without further tearing around the edge), and the label applied to a product surface.

Petition 870180036999, of 05/04/2018, p. 40/87

36/71

Micro-bridge or micro-perforation includes a process where less than 5% (preferably less than 2%, more preferably less than 1%) of the contour or intended edge of the label is left blunt in sections or bridges between the label edge and the matrix , with not a single bridge exceeding 2% (preferably less than 1%, more preferably less than 0.5%, and even more preferably less than 0.1% or less than 0.05%) of the total edge or where they exist only single cut edges (with natural sides forming an edge of the label), as measured along the one or two connecting sides between cut labels from the same backrest. The absolute dimensions of the bridges can also be defined. For example, each bridge should have a maximum dimension perpendicular to the edge direction that is less than 1 mm, less than 0.8 mm, less than 0.6 mm, less than 0.5 mm, less than 0.4 mm, less than 0.3 mm, or less than 0.1 or less than 0.08 mm, for example, up to 0.05 mm. These small bridges are capable of supporting a label within a label backing matrix (the matrix being a residue of label material that is usually disposed after the label is removed), so that the total backrest (of matrix fixed through bridges to the label) can be handled or operated and transported, without having to treat the labels individually. There are usually at least two bridges, usually more than at least three bridges, and more usually four or more bridges around the micron bridge label. It is preferred that there are 10 or less bridges, 8 or less bridges, and 6 or less bridges in the practice of the invention, with the labels extending on average from 25 cm ² to 1,000 cm ² .

[0060] Micropicote, micro-point or small perforation can be carried out completely and easily by selecting appropriate dies in the die cutting procedure. Ordinarily, a die or die hammer or die set is designed or positioned 870180036999, of 05/04/2018, pg. 41/87

37/71 moved to have the total contour of the cut intended to be represented in one or more parts of the die as a complete and continuous edge. When the die is pressed against the surface to be cut, the edge will cut the label back, and where there are openings in the die cut edge, a bridge will remain. This can be seen with reference to figures 3 and 4.

[0061] As shown in figure 3, a rectangular matrix 300 is shown. The matrix 300 has a base 302, a raised sharp edge 304 and a base 306. Clearances 308 are shown along edge 304. These clearances 308 do not they can cut a label material and leave a bridge along the cut edge on the label. [0062] As shown in figure 4, a raised die edge 320 is shown. The raised edge 320 has a cutting edge 322 with a gap 324 along the edge. The gap 324 cannot cut through a label when the die 320 is pressed against the label. The length L of the gap 324 will determine the dimension (width) of the micro-bridges along the line of the cut made to make the edge separable on the label. As noted elsewhere, the width or length of the gap 324 may vary from less than 1 mm, to less than 0.8 mm, to less than 0.6 mm, to less than 0.5 mm, to less than 0 , 4 mm, less than 0.1 mm and can be as small as long as it enables the bridge formed in the cut to stabilize a label within the die, particularly in combination with several microperforation bridges or micro-bridges around the circumference or edge of the label pre-cut into the die.

[0063] The term 'micropicotes' is incidentally used or described in US patent 4,945,709, although it is apparently used in the context of forming small holes in a material, such as the opposite of forming small bridges along a die cut or another cut along an edge.

A technique known as this can be used to define the edge portion 44 of a predetermined width, for example, conveniently in the range of 1/31 inch (8.46 to 25.4 millimeters) by providing narrowly spaced thin perforations to the along line 48. In this case, the bridge material constitutes most of the edge. US patents 6,261,252 and 6,106,492 describe 'micropicote' as a small cell foam.

[0064] Perforation is used extensively in label making, even with conventional postage stamps being considered a form of label. In these cases, a very large part of the wider one is retained (in the case of seals, this percentage is usually between 25% and 60% of the edge being opened or perforated), with the bridge segments being approximately equal. Individual sized bridges and also in these cases can make up as much as 3% -10% of the total edge between adjacent seals or sections.

[0065] Micropon according to the present invention is performed by having a hole along the continuous line of the die cutting edge. The number and size of the holes determine the area that is not cut by the die and that remains as a micron on the micron bridge label edge.

[0066] This invention can be described at least in part as a module to adapt apparatus that removes coatings from a label and applies labels to a substrate, the module enabling the apparatus to apply a delaminated label material or uncoated labels, the module comprising:

a source of label backing or uncoated label sheet;

Petition 870180036999, of 05/04/2018, p. 43/87

39/71 a covering sheet source (from the label backing or separate from the uncoated label);

a roller to guide the label backing or uncoated label sheet after removal from the uncoated label source;

in the case of label backing, a delamination section where the liner is separated from the label backing and, in the case of uncoated label, a separate source of liner;

a cutter matrix and a support roll defining an area through which the label sheet (without a fixed coating, as an original uncoated label or as conventional label backing delaminated label material) can move between said cutter matrix and the support roller;

a laminating roll adjacent to the backing roll defining an area between the backing roll and the rolling roll through which both cover sheet and cut labels from the label sheet can travel between the backing roll and the rolling roll to form a support temporary coating for uncoated label cut. The label moves in a treatment direction, with the leading edge referred to in this document as the leading edge and the trailing edge referred to as the trailing edge. The leading edge is the first part of the label material that is cut by a roll support matrix, and the trailed edge is the last part of a label cut by the roll support matrix. While the trailing edge is still compacted or constrained by the narrowing between the support roller and the die cutting roller, the conductive edge is compacted or restricted by a stabilizing roller against the support roller. There must be at least one stabilizing roll or there can be a series of two rollers. In the form of a roller, the stabilizing roller also swings 870180036999, from 05/04/2018, p. 44/87

40/71 laugh like the laminating roll. In a two-roll format, the first roll would act as a stabilizing roll and could partially or free-laminate the coating and the cutting label, or merely support or stabilize an un-laminated association of the coating and the cutting label, passing this association for a laminating roll while the first stabilizing roll is in contact with each label (for example, the trailing edge) while the laminating roll starts laminating the label (the conductive edge) and the coating screen. The distances between the support or stabilization rollers must always be such that there is at least some pressure applied between the cutting label and the coating both on the trailing edge and on the conductive edge during the transition from cut to stabilization, cut to laminate, and stabilization for lamination (which can be done by the matrix / support roll and the additional one or two rollers, as explained previously). The roller for guiding the uncoated labeling screen of the take-up roller may comprise, for example, a top assembly roller. Between the roller to guide the coated label or uncoated label and the support roll and cutter die, there can be a tension controller, such as a dancer, pneumatic or hydraulic tension controller, spring tension controller and more. The cutter die can be, for example, an alternating cutter die, impact cutter die or a die and support cut roll. In the operation of the module and apparatus, a matrix can be formed by removing cut labels from the coating material or uncoated label sheet and the matrix is wound on a re-roll. The module can be built as a single independent module within a structure or housing that can be attached to said device. The structure or independent housing may have power supplies for the coating and / or the coated label or label without

Petition 870180036999, of 05/04/2018, p. 45/87

41/71 separate liners from the module or as separate independent modules or elements fixed or associated with the module where the uncoated label sheet or label material is cut and attached to a preferably reusable temporary support or liner. Where a laser cutter is used, and there is no restraining pressure provided by the laser cutter, the stabilizing nip or stabilizing bar must be in stabilizing contact with the cut end of the label before cutting at the trailing end of the label be completed. This is very important when the cutting label offset path takes the cutting label on a curved or arched surface and folding would promote separation between the cutting label and the die. Even on a flat displacement surface stabilization is desirable.

[0067] Where a support roll is used, the support roll may have openings on its surface through which reduced gas pressure (vacuum) can be applied to retain the cut label as the support roll rotates, but as noted earlier, this has proven to be harmful, even if the stabilization roller alleviates problems caused by the vacuum against the unsupported / unstabilized cut label. To reduce any tendency of the cutter die to form adhesive or other material on its surface, a lubricant can be applied to the cutter die, such as by means of a lubricator or lubricant or non-stick liquid supplier. An important contribution according to the invention is to use a cooled die cutting system, one or the other or both of the cutting element and / or the supporting element, such as the rotating die, flat die, hammer, support, or something like that.

[0068] In US patent 6,294,038, an apparatus was created to apply labels to the surface of elements when positioning the module or the multiple modules described previously to feed an article

Petition 870180036999, of 05/04/2018, p. 46/87

42/71 compound comprising a temporary combination of said coating (e.g., reusable temporary coating) and the cut label and apparatus including a separator or divider (described later) to remove the cut label from the temporary coating. The apparatus may also include a winding element for winding a matrix comprising the coating from which the cut label has been removed on a roll. An apparatus is also provided for applying labels to the surface of elements, the apparatus comprising the module of the present invention positioned to feed a composite article comprising a temporary combination of said coating and said cut label and said apparatus including:

a separator or divider to remove the cut label from a temporary coating;

a winding element for winding a matrix comprising a coating from which the cut label has been removed from a roll; and a registration guide for the label web between said roll to guide said label web or sheet after removal from the label source. The apparatus can supply the roller to guide the label like a top mounting roller, and between the roller to guide the label and the support roll and cutter die, there may be a tension controller, and the cutter die can be a die cutting roll, and a die is formed by removing cut labels from the label sheet and the die is wound on a re-roll. The support roll, as noted, should not have reduced pressure or vacuum applied to support the cut label, although some may be provided as the ability to move and wrinkle the coating is reduced by the stabilizing roll. The stabilizing roller (or stabilizing lamination roller) must come into contact with the conductive edge of the cutting label while the die cutting roller maintains with Petition 870180036999, from 05/04/2018, pg. 47/87

43/71 pressure on the trailing edge of the cut label. This contact at both ends of the cut label provides the stabilizing effect as the cut uncoated label is transported to the laminating roll. Compression at both ends of the label can be released at the trailing edge since pressure on the leading edge stabilizes the relative movement (prevents relative movement) between the cut label and the liner. This device can have the inventive subcomponents or module (the delaminator, support cutter / matrix, and re-roller with stabilization roller) as a single independent module within a structure or housing that is attached to the device. The apparatus can provide reduced gas pressure (vacuum) in other parts of the screen travel paths to stabilize movement, but it is not necessary and at least less preferred to retain the cut label as the backing roller rotates. The present invention can eliminate part of the structure in this process, for example, eliminate the vacuum support for the label, since the micropicote now enables the pre-cut microperforated label backrest to be transported with the label fixed by the bridges to the matrix and even the stabilizing roller enables a complete separating cut (all edges of the label form are completely cut) since the roll can support both the cut label and the coating together without movement between them.

[0069] The present invention would also allow the use of laser cutting in the process, with the trailing edge of the label not being completely cut until the conductive edge is gripped or compressed by a stabilizing roller and a support roller.

[0070] A method is also described in US patent 6,206,071 for enabling a coated label applicator to accept uncoated label foil for surface application of elements comprising attaching a module of the invention to an application applicator.

Petition 870180036999, of 05/04/2018, p. 48/87

44/71 label coated so that a compound of:

coating sheet as a temporary coating sheet and uncoated labels cut from the uncoated label sheet is fed to a coated label applicator where coated label is normally directed at the coated label applicator. A method of applying uncoated labels to a substrate after enabling a coated label applicator to accept uncoated label foil for application to the surface of elements is also described, in which cut uncoated label is removed from a temporary coating foil, and the cut uncoated label is applied to a substrate. This method can be practiced additionally by which after removing the uncoated label cut from the temporary coating sheet, the used temporary coating sheet is rolled onto a roll. Then, the roll on which said temporary liner sheet is wound is used to feed liner as a source of liner sheet in a module comprising:

an uncoated label sheet source, a roll to guide an uncoated label sheet after removal from the uncoated label source, a cutter die and a backing roll defining an area through which an uncoated label sheet can move between a die cutter and backing roll, a laminating roll adjacent to the backing roll defining an area between the backing roll and the rolling roll through which both coating sheet and uncoated labels cut from the label sheet without coating can move between the backing roll and the rolling roll to form a temporary backing support for the uncoated label liner,

Petition 870180036999, of 05/04/2018, p. 49/87

45/71 where a roll must maintain pressure between the cutting label and the coating always between cutting the trailing edge of the label and rolling the leading edge of the cutting label into the coating. [0071] It is also desirable, as an alternative to the present invention, to provide a pre-rolled (and preferably pre-printed) source of partially separated or partially segmented microperforated uncoated labels on a temporary support, which may or may not be a temporary recyclable support or a thin support. The source roll itself is also unprecedented, as a label with the adhesive backing, with a release coating on the surface to which the adhesive on the back does not stick, with microperforation bridges supporting the label in a matrix that does not was previously supplied in a coating, including a thin coating and a reusable temporary coating. [0072] The unprecedented supply roll can be produced in several different ways, depending on the way in which the supply can be used at the end. Among the most useful methods of building this pre-rolled uncoated label format are:

provide a flow of uncoated labels (for example, with adhesive coated on them) outside the manufacturing line, before being rolled up, partially cut individual labels on the web with the invention's microperforation process, and apply the web with the labels partially cut to the temporary support, and then roll up the label / support compound, with or without a core support;

provide a flow of uncoated labels (for example, with adhesive coated on them) outside the manufacturing line, and before the label backing is rolled up, partially cut individual labels on the web using the micro-bridging techniques of the invention, and separate the labels of the structure (s) segment (s) 870180036999, from 05/04/2018, p. 50/87

46/71 cutting area with the individual uncoated labels spaced and supported on the reusable support, then roll up the microperforated label / support compound, with or without a core; the labels can be separated from the structure segment (s) before, during or after applying the labels to the temporary support (in any of these listed alternatives);

supply a roll of uncoated labels, unwind the uncoated labels, or partially form or cut individual labels by microperforation or micropore techniques and associate the flow of labels (with or without the structure segment (s)) with a temporary support, remove the structure segment (s) from the uncoated label sheet before, during or after association with the temporary support, except that the labels are partially cut on the temporary support, and then apply the compound individual label / support to a label applicator or roll the label / support compound onto a roll (with or without a core) prior to introduction to an applicator. Partially cut means that the labels are modeled, but that some bridge remains between the label shape and the matrix; and supply a label backing roll (preferably printed in advance), delaminate the label material from the liner and cut the label (with perforation, micro-bridges or complete separator cut) and a roll maintaining pressure between at least part of the cut label and the coating always between cutting the trailing edge of the label and laminating the leading edge of the cutting label to the coating until the label has been attached to the coating. The matrix can be removed conveniently during the process according to standard methods.

[0073] In the practice of these three methods, several alternatives and options can be used. The uncoated labels or label backing 870180036999, of 05/04/2018, p. 51/87

47/71 can be printed at any time, such as before applying the adhesive, before or after cutting the individual labels, before or after separating the labels from the structure segment (s), or before or after application of uncoated labels to the temporary support. With thin coating, it is highly preferred, if not required, to print labels before they have been applied to the thin coating.

[0074] The uncoated label sheet or individual labels can be applied to the temporary support, can be partially cut or partially cut into individual microperforated labels, can be printed, and can be applied subsequently to surfaces in any other mode processed on equipment commercially available, and in similar processes such as coated labels are handled. Once the coated label roll or flow or uncoated labels on composite of temporary support material have been formed, it can be used in a similar manner to the composite of uncoated labels / coated label temporary support manufactured in line such as described earlier. The compost can then be fed to a conventional label applicator.

[0075] A method of enabling a coated label applicator to accept uncoated label foil for application to the surface of elements according to this invention can be described as comprising associating a source of partially pre-cut labels with micro-bridges, or labels completely separated by cut on a reusable coating sheet roll to the label applicator so that a compound of:

the reusable temporary liner sheet and micro-cut or through-cut uncoated labels are fed to the label applicator where the label is

Petition 870180036999, of 05/04/2018, p. 52/87

48/71 usually aimed at the label applicator. The cut label can be removed from the temporary liner sheet, leaving the matrix behind when cutting the micro-bridges by breaking, and the cut label is applied to a substrate. After removing the cut label from the temporary liner sheet, the temporary liner sheet would normally be rolled up in a roll, and it may or may not be reused. After the temporary liner is rolled onto a roll, the roll is unwound and the uncoated label can be re-applied to the liner to use as a reusable temporary liner. After the roll is unwound and the label is applied to the temporary coating sheet to form a recycled roll, the label supported by the recycled roll is fed to the coated label applicator where the coated label is normally directed to the coated label applicator. The roller is used to feed the label into a temporary reusable coating as a label source, with applicator operating normally through the steps in the applicator comprising:

fold the label into a temporary coating to partially remove at least part of one edge of the temporary coating label, have at least the raised edge placed in contact with a surface to which the label is to be applied, and attach the label to the surface .

[0076] As with the label / temporary support compounds manufactured in line, the temporary support is pulled from the labels in the applicator leaving the matrix behind when breaking the bridges formed by the microperforation process, the rolled support, and the unwound support. labels or label backing applied to this.

[0077] Another way of providing rolled sheet material according to the present invention comprises a method for creating

Petition 870180036999, of 05/04/2018, p. 53/87

49/71 a label on a reusable temporary charger comprising the steps of:

printing an image on at least one side of a first sheet material;

applying adhesive to at least one side of the first printed sheet material;

pre-cut sheet material into individual labels when punching, making micro-bridges or cutting in a separating manner to leave bridges or no bridges between labels and an array, while maintaining pressure between the cutting label and the coating always between cutting the trailed edge from the label and lamination of the conductive edge of the cutting label to the coating;

applying a face of the individual labels to a temporary loader sheet to form a label backing sheet; and wrap the label backing sheet on a label backing roll or use it inside an applicator for coated labels. [0078] This method will usually have a label backing from the label backing roll fed to a label applicator, where labels from the label backing are applied to substrates, and the temporary loader is collected as a roll, with the matrix fixed or with the matrix extracted separately from the charger. The method desirably also has the collected temporary loader roller subsequently supplied as a coating for labels. The method is also practiced by having the temporary loader roll collected (with the matrix removed) subsequently supplied as a reusable temporary loader after repeating steps a), b) and c) on a second printed sheet material that is different from the first sheet material. Different from the first sheet means that it is a different sheet, not that printing is required to be different on the second printed sheet material.

Petition 870180036999, of 05/04/2018, p. 54/87

50/71 [0079] Reference to figure 1 will help to explain the module that can be used in the practice of the present invention, using the example of uncoated label backrest, although a simple change in this configuration (which will be described later) that enable use of conventional label backing (coated label material) will enable the use of any label material. An unwinding magazine 2 having an uncoated label roll 4 is provided. The unwinding loader 2 is preferably driven as it helps to control the tension on the uncoated label 6. A roll 8, preferably a top mounting roll 8, aids in removing the uncoated label 6 at an angle at point 10 , between the top assembly roller 8 and the uncoated label roll 4. The uncoated label roll 4 preferably has the uncoated label 6 rolled up so that the adhesive face 12 of the uncoated label faces the center 14 of unwinding 2. The uncoated label 6 is optionally advanced in the system to a tension control element 16 which optionally is a dancer. It is also desirable to have uncoated label material 18 after advanced removal on a registration roller or pull / registration roller 20. These two elements, the dancer 16 and the registration roller or pull / registration roller 20, are modalities preferred, a location where the uncoated label sheet 22 can be temporarily supported in a reusable magazine. In this figure, the uncoated label sheet 22 is fed between a backing roll 24 and a cutter die 48, so that an uncoated label sheet 22 is fed towards the cutter 48 confronting the backing roll 24. The cutter 48 will have a die face (not shown here, but described in figures 3 and 4) that enables microperforation of the label backrest. The backup roller 24 does not require a vacuum pressure support roller 24 because the

Petition 870180036999, of 05/04/2018, p. 55/87

51/71 lamination 32 act as a stabilizer roll. The support roller 24 has a surface 26 that faces the cutter die 48 which cuts the uncoated label according to the cut-out, microperforation or cut-out cut design on the die face (not shown). The cutter matrix 48 confronts the adhesive face of the uncoated label 22 (with a thermal, pressure sensitive, or water-soluble adhesive or organic solvent) to form the perforated cut, separator cut or with micro-bridges along the edge of a label on the uncoated label sheet 22. The distance k between the point of contact between the cutter die 60 and the support roller 24 and the point of contact between the laminating roller (or the first stabilizing roller) 32 and the roller support material 24 must be at least slightly less than the length I of the cutter label material 44. The length k must be measured as the coating dimension along the surface of the support roller 24. The uncut matrix cutter label 28 with its adhesive face (for example, pressure sensitive adhesive, thermal adhesive, solvent activated adhesive, etc.) 30 is transported on the surface 26 of the support roller 24, with a cutter matrix 48, in the direction of a laminating roller 32 (which is is acting as the stabilization roller and rolling roller in this construction). A liner 34 is fed from a source (e.g., a roll, not shown) of recyclable / reusable liner material. The screen direction guide rollers 36 can be used to guide the coating 34 towards the laminating roller 32. The coating 34, with its release coating surface 38 facing the adhesive coated surface 30 of the uncoated label die template 28, is laminated with the die cut uncoated label 28 to form a uncoated label / temporary loader system 40, comprising a potentially reusable coating / loader 42 having a series of microperforated die cut labels

Petition 870180036999, of 05/04/2018, p. 56/87

52/71 previously uncoated 44 with its adhesive faces 46 next to the potentially reusable carrier / coating. This uncoated label / temporary loader system 40 can then be treated and applied to a substrate using conventional coated label applicator systems (not shown) effectively such as a coated label, even if initially provided as an uncoated label. The matrix is removed from the coated uncoated label material by applying sufficient force to raise the label and break the bridges formed between the label and the matrix. The uncoated label / temporary loader system 40 can then be divided or separated at the adhesive interface and the release surface of the temporary reusable coating. Label 44 can be applied to a substrate (not shown), and the coating can be rolled up in a capture system (for example, a roll, not shown). The used coiled coating (not shown) can then be used as the coating source 34 which is fed in the direction of the rolling roller 32. The tension control elements 64 which are basically a controlled circuit are associated with the transducer roller 56 and the dancer 16 to ensure that tension can be adjusted as needed as the die 50 passes over the guide roller 57.

[0080] A die 50, comprising the residue from the uncoated label 22 after the die cut label 28 is removed from the uncoated label 22, is transported away from the backing roll 24 with a die cutter 48 in the direction of a die rewinder (for example, a take-up rewinder) 52. There is preferably an output pull roll 54 and a transducer roll 56 between the die cutter 48 and the die rewinder 52. This complete module can be fixed or inserted to the conventional coated label applicator so that the label system without

Petition 870180036999, of 05/04/2018, p. 57/87

53/71 coating / temporary loader 40 is fed to the conventional coated label applicator system at the point where a coated label is normally fed. This physical fixation can be done by biting the module into the receivers on the device, screwing or soldering the module to the coated label application device, by associating an additional structure adjacent to the coated label application device, or by any other device physical to associate the module with the coated label applicator. The module can also be a stand-alone unit, allowing the reusable coating to be fed into the coated label applicator system. In this way, the module does not have to be physically fixed directly to the structure of the coated label applicator.

[0081] This system, as mentioned earlier, can be used with commercial applicators, conventional applicators, conventional label coatings, and uncoated label backing and commercial rolls. Other optional elements within the coated label applicator include a non-sticky circumferential surface feed roller, a hardened support vacuum cylinder cooperating with a cutting cylinder having a radially extending knife blade, which in turn cooperates with a wiper roller that applies liquid release material to the blade after each cut, and transport device having many unique features. The conveying device may include a plurality of conveyor belts which are thus spaced in a direction transverse to the direction of conveyance of labels, and a vacuum chamber helps the adhesive of the labels to hold the labels in position on the conveyor belts during transportation. The conveyor belts can typically be substantially circular in cross section in order to have a minimum area to fit with the label adhesive, and the labels are separated from the conveyor belts by means of a

Petition 870180036999, of 05/04/2018, p. 58/87

54/71 plurality of extraction rings with non-sticking surface that extend upwardly above the upper surface of the conveyor belts, and which are associated with a peeling roller that bends the labels upwards as they are deflected by an extractor such as extraction rings , blades, rollers or the like, or even lifted by means of reduced pressure supports (for example, vacuum lifters). From the peeling roller and extractor the labels are moved directly to contact a moving element. Where, as typical, labels are moved to contact moving envelopes, labels and envelopes pass through the press rollers whereby the pressure sensitive adhesive is activated by pressure.

[0082] It has been found that there are some unique interactions between stabilization procedures, cooling procedures and the use of microperforations (as described in this document) in efficiency and quality of performance under certain conditions. For example, the method can be practiced as a method for forming a cut label on a coating. A web of label material is fed to a cutting station comprising a coolable die head. The die head described in this document with internal cooling is preferred. The process is used in forming a cut label material having an adhesive face over the cut label material. The label material is cut to provide a matrix adjacent at least one leading edge of the cutting label and one trailing edge of the cutting label (with the side of the label also cut). The distance between the leading edge and the trailing edge defines a length for the cut label. The matrix head is cooled, and in the preferred method of cooling by passing coolant through the internal volume of the matrix head. A cut lining screen is fed to the set 870180036999, of 05/04/2018, p. 59/87

55/71 rollers close to the adhesive face. It was found that the combination of microperforations (as described in this document), physical stabilization of the label (without vacuum, as defined in this document) and the cooled die head (as defined in general and specifically in this document) produces a total effect that established better performance than establishing the use of the elements separately.

[0083] Particularly, the combination of all three elements both reduces ironing transfer of the adhesive and substantially reduces such adhesion resistance between the adhesive layer and the die cutting edges as well as to prevent the label backing and / or the die are lifted from the roll holder and interfere with the cutting and application process. For example, without cooling, even with vacuum stabilization, there can be both ironing and label lifting (although the latter can be greatly reduced with proper stabilization). Without stabilization, there will often be label lifting, especially with quick use and without microperforations. Without microperforations, label removal will often lift or partially remove matrix from a support. Without cooling, ironing adhesive transfer will often occur. The combination of all three vacuum-free stabilization, cooling and microperforation techniques overcomes all three deficiencies in separate processes.

[0084] The process is preferably performed with the die head being structured to provide microperforations in the cut label material with less than 1% of an entire cut (along a single edge or around the total periphery) retaining connective material through the cut with at least four consecutive cuts defining a border or an entire label.

[0085] One aspect of a preferred modality of the present inPetition 870180036999, of 05/04/2018, p. 60/87

56/71 The invention that helps differentiate the invention from other processes and materials is the use of a carrier sheet in a generally smaller scale in which the label material is originally applied. This is because most commercial label manufacturing is in large sheets that are then converted into smaller sizes (narrower widths) for application. In the present invention, since the charger is reused, it is usually converted only once, and is at least slightly larger than the labels applied (for example, labels as narrow as 1 cm, 2 cm, 5 cm or the like can up to 10, 15, 20, 25 or up to 30 cm wide). The carrier sheet, as better explained elsewhere in this document, can also be thinner than coatings that can be used in other manufacturing processes.

[0086] A printer, such as a thermal printer (ink support, ink diffusion, mass transfer, etc.) or a printer such as a bubble jet printer, an inkjet print head or the like it can also be provided in association with the conveyor belts to print distinctive marks on the label release liner just before removing the labels from the conveyor belts. If the ink is a hot-melt ink, a heated printing cylinder is preferably provided on the label release coating faces to heat them so that they are receptive to the hot-melt ink.

[0087] Uncoated labels may comprise a substrate having a release coated face and an opposite face coated with pressure sensitive adhesive. The label substrate can be any foil, film-forming or substrate-forming material, preferably a flexible material such as paper, synthetic paper, non-woven sheets, fabric sheets,

Petition 870180036999, of 05/04/2018, p. 61/87

57/71 polymeric film or sheets and more. Polymer sheets and ethylenically saturated monomer films (polyvinyl resins, polyolefins, polyesters, and more) and sheets of fabric (eg sheets, nonwoven fabric, braided fabric, knitted fabric) are very useful. The adhesive can be a thermal adhesive (for example, polyvinyl resin, polyamide, polyolefins, polyester, etc.), pressure sensitive adhesive (for example, polyacrylate, polymethacrylate, polyurethane, polysiloxane, etc.) or solvent-activated adhesive ( for example, natural resins, synthetic resins, gums, esters, resins soluble in organic solvent, resins soluble or dispersible in water, polyvinyl alcohols, gelatines, polyvinyl pyrrolidone, poly (meta) acrylates, polyolefins, polyvinyl chloride, polyvinyl chloride, polyvinyl acetate, polyvinyl acetals, cellulose resins, cellulose acetate butyrate and mixtures thereof.

[0088] The following method steps can be practiced to apply uncoated labels to temporary coatings: (a) feed coating or tape comprising a substrate with a release coated face and an opposite face coated with pressure sensitive adhesive in a first direction; (b) partially cut the tape with microperforations in individual labels in a cut position while the tape is being fed in the first direction; (c) continuously transport the labels away from the cutting position in a second direction, by placing the labels and matrix fixed on conveyors, with the face coated with adhesive coming into contact with a conveyor; and (d) continuously separating the labels from the carrier and the die while breaking bridge material between the label and the die, while simultaneously applying the separate labels to the moving reusable temporary supports. It is also possible to provide printing on the face with release liner while it is being transported in the second direction 870180036999, from 05/04/2018, p. 62/87

58/71 tion, and (e) continually apply printed labels to moving elements.

[0089] The following method steps can also be practiced for applying uncoated labels to moving reusable temporary supports: (a) feeding the uncoated label sheet comprising a substrate with a release coated face and a coated opposite face of pressure-sensitive adhesive in a first direction, (b) partially cut the sheet with microperforations in individual labels in a cutting position while the sheet is being fed in the first direction, by placing the face with the sheet release liner in contact with a hardened support, and rotating a separating element such as a knife blade extending radially from a cutting cylinder to come into contact with the sheet, the knife blade extending across said first direction, (c) continuously transporting the labels away from the cutting position in the second direction, and (d) continuously applying labels to moving carriers shifting when removing the matrix labels when breaking the bridge material.

[0090] Typically the elements to which the labels are applied may comprise envelopes, boxes, jars, bottles, packages, or the like moving in which case there is the additional step of, after applying a label to a moving element, pressing mechanically the pressure-sensitive adhesive-coated face of the label to contact the element to ensure proper adhesion between them, for example, when passing them through a pair of press rollers if thin enough or when using both a pressure of rear support as well as a front application pressure surrounding the label and the elements.

[0091] Other elements that desirably are present in the

Petition 870180036999, of 05/04/2018, p. 63/87

59/71 modules include, for example, a lubricant application roller 58 that applies lubricant or releases material to the cutting surface 60 of the die 48 where the die cutter 48 makes contact with adhesive (directly, or by cutting through the label to the adhesive on the other side), which is preferably in contact with the pressure sensitive adhesive surface (not indicated) of the uncoated label 22. Apparatus or detection elements (eg 64) may be present at various locations on the roll for detect and indicate to an operator or control system (for example, computer or computer program) that the voltage must be adjusted by the movement of elements or speed adjustment of the system. The vacuum pressure support roller 24 can have areas with negative pressure V to hold the labels, or areas with variable pressure (for example, negative pressure to retain the label, neutral or positive pressure P to release the cut-off label). matrix 28).

[0092] The cutting apparatus may include a hardened support vacuum cylinder, rotatable about an axis parallel to the rotation axes of a guide roller and a feed roller. At least the circumferential surface of the support vacuum cylinder must be hardened to perform a support function. A vacuum applied through the vacuum cylinder (vacuum cylinders per se are well known) retains the uncoated label sheet, and the labels subsequently cut from it, on the peripheral surface. Cooperating with the hardened support vacuum cylinder to cut the foil tape into individual labels, a cutting cylinder having a radially extending knife blade (or radially spaced knife blades if desired) can be provided. The cylinder is rotatable about an axis parallel to the axis of the support cylinder, and devices are provided (such as a frame) to mount the cutting cylinder adjacent to the support cylinder so that the cutting blade does exactly

Petition 870180036999, of 05/04/2018, p. 64/87

60/71 very little contact with the hardened surface of the cylinder.

[0093] To prevent the knife blade from sticking to the sheet as it is being cut into labels, a small amount of liquid release material must be applied to the blade or sheet between successive cuts. This can be accomplished, for example, by means of a cleaning guide roller which is a felt roller impregnated with release material, and is mounted for rotation around an axis parallel to the axis of rotation of the cutting cylinder, and adjacent to the cylinder, so that as the blade is turned away from contact with the hardened support surface of the cylinder, it fits into the felt and picks up a small amount of release liquid, rotating the cleaning roller incrementally as it moves. it does so. This is just one of the many obvious ways to apply release layers, others including sprays, rollers, drips, binders and more.

[0094] The cutting length of the labels is determined by the ratio of the feed roller rotations to the cutting cylinder rotations (and cutting blade quantity). This ratio can be changed by any conventional mechanism such as gears, single speed clutches, or servo motor controls.

[0095] The backup vacuum cylinder carries the cutting labels in association with the temporary reusable label. Additional transport of the now temporarily coated label is done to carry it away from the cylinder, in the end to come into contact with moving elements, such as envelopes or containers moving on a path. Transport can be done by tensioning the uncoated composite label, or by supporting it on a conveyor, which may already be a part of the coated label applicator. The adhesive on the sticky side of the label facilitates adhesion of the labels to the temporarily reusable coatings so that they can transport the labels in a transport direction, to ensure

Petition 870180036999, of 05/04/2018, p. 65/87

61/71 that the labels remain in place until it is desired to remove them for the coating. A vacuum cylinder is also preferably provided to secure the uncoated cut label in transit for application to the reusable temporary coating. The vacuum pulls air through the spaces on the surface of the cylinder, thus providing a holding force for the labels on the support or cylinder.

[0096] The uncoated label sheet may have already been printed, or it may be desirable to print distinctive marks on the coated release faces. For this purpose a printer, such as an inkjet print head, thermal transfer (mass or ink), contact printer (lithographic, embossing, engraving, etc.) or similar structure, can be provided. If the inkjet print head applies hot-melt ink, just before the print head a heated print cylinder is preferably provided to heat the face with label release liner to make it receptive to ink coming from the head Printing. Once the labels have been printed and it is desired to apply them to moving elements, such as envelopes in the desired path, in addition to removing the force from the vacuum chamber it is desirable to positively separate the labels from the reusable temporary support. For this purpose, an extraction system to remove labels from the temporary reusable coating can be used. A type of extractor system comprises one or a plurality of extractor elements, such as extractor rings having non-stick circumferential surfaces, associated with a peeling roller. After separating the labels from the temporary reusable support, the pressure sensitive face of each label is fed to come into contact with an element such as an envelope, and the envelope with the applied label can pass through press rollers whereby the adhesive sensitive to pressure is activated to ensure adherence of the labelPetition 870180036999, from 05/04/2018, pg. 66/87

62/71

I go to the envelope. If the element to which the label is being applied is too thick for use with press rollers, other conventional instructions for applying pressure to the back of the element while applying pressure to the top of the label can be used. Lathe-like mechanisms, pincers, flat plates alternating on both surfaces and more can be used.

[0097] To remove the labels from the reusable liner or temporary support, a separation mechanism will be provided by the coated label applicator, which is ordinarily part of this device's function of removing coatings from the labels inside the device. The separation mechanism comprises one or more extraction elements, preferably slides, rollers, ramps, plates, sheets, or extraction rings, which extend upwardly above the tops of the label without temporarily supported coating. Another element that is not usually flat in the system, such as a roll or edge (for example, to fold the label less coating over a non-flat area to lift an edge that can be released for fitting and support) is used to fold or deflect each label away from the reusable temporary liner, usually by lifting an edge or corner that can be used to lift the remaining label from the reusable temporary liner. The extractor, at least the parts that will come into contact with the adhesive faces of the labels, can be made of non-sticky material or coated with it, such as cross-linked polytetrafluoroethylene, polysiloxanes or polysiloxanes. The extractor can also be the container or substrate that is to be labeled. A peeling roller, if present, can be mounted for rotation around an axis parallel to that of a vacuum roller, and can be supplied just above the reusable liner temporarily and just before the extractor. A peeling roller can help remove labels from the temporary reutiPetição 870180036999, from 05/04/2018, p. 67/87

63/71 liable to cause an upward fold in each label, thus causing a part of the label to move in a direction that is tangent to both the peeling roller and the extractor, and is deflected by the extractor. The extractor can rotate with a drive shaft, or it can be mounted freely on a drive shaft in such a way that relative rotation between them is possible, or it can be a fixed blade or freely rotating blade. Drive mechanisms or brakes can be placed inside the module in various elements that may need or tolerate a drive mechanism or brakes, such as, for example, 8, 14, 20, 26, 32, 52 and 54.

[0098] Figure 2 shows a system 100 in which a roll 102 of printed label material 104 is coated with adhesive prior to association with a temporary loader 106 which is supplied from a roll 108. After the initial treatment (e.g. on the unrolling joint table 110, cleaning in a screen cleaner 112, and treating the crown discharge with a crown unloader 114), the prepared and pre-treated label material 116 is transferred to an adhesive layer unit 118 where adhesive (for example, a thermal or fusion adhesive) is applied. The adhesive coated backrest 120 can then be sent to a cooling unit 122 and then to the die cutting and application unit 124. Within the die cutting application unit or module 124 may be a feed / register roll 126 and an optional die transfer die cutting station 128. The rotating die can also be cooled to prevent sticking or adhesive transfer. As the individual labels (not shown) are cut with microperforations, they can be (according to this description of this aspect of the invention) supported within the die cut by the vacuum transfer segment 128 and applied (adhesive side down) or adhesive side up) in a carriagePetition 870180036999, from 05/04/2018, p. 68/87

64/71 temporary generator 106 that has been unwound from a supply roll 108. The loading material 106 can certainly be recycled or reused material. Within the die cut with the vacuum transfer segment 128 may be, for example, an output die pull roll 134 that removes the cut die (not shown), a temporary input load pull roll 136 and a lamination 138. Adhesive laminated coated labels (not shown) in the reusable temporary loader assembly 140 are then transported to a take-up rewinder 142 and the die 144 is received by the die rewinder roll 146.

[0099] Figure 5 shows an enlargement of the alternative system 500 to use the conventional label backing 502 and delaminate the label material 506 from the liner before cutting the label material and liner backing. Figure 5 shows a subcomponent system for delamination and re-rolling of the conventional coated label backrest 502. The conventional coated label backrest 502 is fed to the system 500 with the backrest 502 being divided into two screen streams, the material flow of label 506 and coating flow 508. Coating flow 508 is guided by roller 514. The flow of label material 506 is fed between a cutter die roll 510 and a backing roller 512. The center point P1 (at figure 5, and 3 in figure 6) of contact between the cutter die roll 510 and the support roll 512 is identified. There is also pressure provided by the cutter die roll 510 and the support roll 512 along the path of the label material 506, and that may be sufficient pressure for some modest distance along the narrowing between the cutter die roll 510 and the support roller 512. In figure 6, the cutting label 516 (in figure 5) and 614 (in figure 6) is then moved towards the support or stabilizing roller 618 and another point of narrowing f (in figure 6 ) It is formed. The coating material 614 is

Petition 870180036999, of 05/04/2018, p. 69/87

65/71 fed between the stabilization roller 618 and the support roller 612 and the distance along the surface of the support roller 612 between the narrowing points “e” and “f” is at least approximately equal to the length of the leading edge to the trailing edge of individual cutting labels (not shown) on cutting label material 516. As noted, “e” and “f” represent the maximum pressure points (the center points) in the narrows between the die template roll cutter 610 and support roll 612 and stabilization roll 618 and support roll 612, respectively. There is sufficient pressure supplied by these pairs of rollers (ie, the narrows between the cutter die roll 610 and the support roll 612 and the stabilization roll 618 and the support roll 612) to provide stabilizing pressure, so the cut label length does not have to be absolutely as long as the linear surface distance along the support roll 612 between the nip points “e” and “f” to provide stabilizing compressive forces on the cut label 614 and between the cut label 614 while it is between the nip between the cutter die roll 610 and the support roll 612, and the liner 616 and the cut label 614 at the nip f. The expression “approximately equal to the distance between the nip points between a) the cutter die roll and the support roll and b) the stabilization roll and the support roll”, therefore, means the distance where stabilizing pressure is provided in the narrows so that both ends of the label are under pressure from the press rollers at both ends of the cuts in the label along the direction of movement of the label through the system. This distance cannot be readily quantified (even in relation to the length of the label) because it is dependent on roll diameters, roll compressibility, ability to extend from the label material and other factors. These distances, that is, the distance that is approximately equal to the provision 870180036999, of 05/04/2018, p. 70/87

66/71 tance between the narrowing points between a) the cutter die roll and the support roll and b) the stabilization roll and the support roll, can be readily determined by routine experimentation based on the precepts of this specification by simply moving the stabilizing roller 618 backwards along the movement path A of the cutting label material flow 516. [00100] Figure 5 shows a schematic presentation of the delamination / cutting / re-laminating apparatus 500 of the present invention. The backing of liner material in a magazine 502 is intercepted by a divider 504 that delaminates the label material 506 from the magazine material 508. The label material 506 passes into a cutting area between a backing roller 510 and a die roll 512. The cutting label carrying the matrix joined by the microsteps 516 is additionally transported to the device 500. The separate loader 508 is transported on a support roll 514. The loader 508 and the stable cut label material 516 are re-routed between the rollers 518 and 520. After re-rolling, matrix 524 is extracted from the magazine with the cut label on it 522. The capacity of the micro-bridges (not shown in this figure 5) enables the critical transport of a stable cut label material 516 between the cutting zone on the support 510 and the cutter die region 512 for the re-rolling between the rollers 518 and 520. Without the micro-bridges in an area where the cutting label material is independent and is not supported by other surfaces or pressure, the matrix would separate from the label, usually with the labels being unsupportable as they cannot be provided with individual supports.

[00101] Figure 6 shows a schematic presentation of the apparatus 600 which has a stabilizing roller 618 in the system to allow formation of the cutting label backrest in a loader 620 according to another aspect of the invention. Label material is not

Petition 870180036999, of 05/04/2018, p. 71/87

67/71 cut 602 is fed to the nip between a support roll 612 and the die cut roll 610 which form a nip at point e. A stabilizing roller 618 forms a nip at the point f between the stabilizing roller and the support roller 612. The distance between the nip points “e” and “f” must be equal to or less than the length of the label 614 just after to have been cut. Preferably, the distance between the narrowing points "e" and "f" is less than the length of the 614 label, as explained elsewhere. The loading material 616 is also fed to the narrowing f between the stabilizing roller and the supporting roller 612 to be laminated to the cut label material. After passing the narrowing point f, the die 622 can be formed by removing it from the cutting label material in the carrier 620. The stabilizer bar enables the label material 602 to be cut completely (without microdots) from the matrix 622. The 614 label is effectively supported at both ends of the label by the two nipples e and f. The label material 602 can be micro-bridged for additional stability, but this is not necessary with the 618 stabilizing roller.

[00102] Figure 7 shows a side view of a die cutting head system 700 according to preferred practices of the present technology. The die cutting head system is supported on a 704 axis that can be driven or free-rotating, and the die head 702 itself is shown with the extended cutting points 708 (for example, for microperforation) and an area relatively large plane B706B between cutoff points 708. Although not limited to this theory of operation, it is believed that both the need for cooling and the effectiveness of the cooling operation are increased by the presence of large separation areas, especially where the separations are greater than 80% of the area

Petition 870180036999, of 05/04/2018, p. 72/87

68/71 of total surface, and more importantly where the flat areas (or areas extended between the cutting edges, which can be smaller than the flat) are greater than 85%, greater than 90% or greater than 95% of the surface area of the die face of the die head. It is a theory that because of the extensive amount of flat surface exposed to the adhesive or to which adhesive can pass through the cut coating, the surface is more susceptible to adhesion or transfer by the adhesive. Cooling the exposed surfaces 706 and to a lesser extent of the cutting edges 708 during label cutting prevents softer and stickier adhesive from sticking to the die cutting tool surface. Therefore, it is a function of the present system to be able to cool the die cutting head 702 surfaces by passing coolant through the interior of the die head, and to remove and replace (recirculate) coolant to maintain a desired temperature and relatively smaller on the surface 706 of the die head 702. To make this cooling easier, a cooling material (usually a liquid, such as chilled water, propylene glycol, etc.) is fed into channel 710 so that the liquid flows close to the flat surface 706, as shown by distance 716. This distance must be selected to achieve a balance between the structural needs of the die (it cannot be too small or die cutting pressures can cause the die head collapse or fold) and it (716) cannot be too large and channels 710 712 are too small, or there will be insufficient heat removal (cooling) from the 706 surface. It is believed that an absolute minimum thickness 716 is 2 mm, and that the largest thickness should be around 100 mm, although the largest dimension can be increased more easily by providing a cooler coolant in the

Petition 870180036999, of 05/04/2018, p. 73/87

69/71 system. A narrower range for consideration would be between 2 and 50 mm, between 2 and 40 mm, between 3 and 40 mm, between 4 and 40 mm, and between 5 and 40 mm for thickness 716.

[00103] There are also alternative methods for cooling the die cutting elements than the preferred structures and methods described above. The technology is used to cool the cutting edges sufficiently to prevent adhesive sticking to the cutting edges. Cooling air streams can be used alongside one side of the rotary cutter die when the cutting edges are away from the adhesive, a Peltier electrical system can be built to cool the surface, and any other cooling function can be used to cool the cutting edges sufficiently according to the needs of the system. As also noted elsewhere, the adhesive can be cooled to an extent where it can be cut without gluing and also not be cooled either to shatter or fragment when contacted by the die cutting edge.

[00104] A preferred embodiment of this die cutting method is to use the cutting tool to cut a label substrate that has an adhesive surface that is exposed (on first contact) to the cutting tool. By cooling the cutting tool to a temperature that is below the glass transition temperature of the exposed adhesive, a significant reduction in both the formation of adhesive in the matrix and the collection of airborne contaminants to adhere to the matrix can be achieved. The glass transition temperature of an adhesive (Tg or Tg1) is a well-recognized characteristic of an adhesive and represents a temperature at which an adhesive (or other plastic material) changes from a soft material that flows to a hard, brittle, similar material to glass. An exclusive characteristic of an adhesive is that at temperature Tg or below, it loses a lot

Petition 870180036999, of 05/04/2018, p. 74/87

70/71 or completely loses its adhesive characteristics. During the attempt to cut the rotating die, where the exposed adhesive material necessarily comes into direct contact with the cutting tool system, it is desirable to reduce the adhesion between the adhesive and the die. This reduction in adhesion or adhesion reduces formation in the matrix, both of the adhesive itself and of the materials that accumulate in the adhesive. In this preferred embodiment, the cut or partially cut label material is less likely to stick to the cutting tool. This unique cooling technique eliminates this problem. The actual temperature of the point of contact between the matrix and the adhesive is the relatively important point at which the lowest or cooled temperature must be maintained. That is, the internal mass of the matrix does not need to be constantly at a temperature below Tg, but the sheets, or edges that actually come into contact with the adhesive, and preferably also the flat areas between the sheets that can come in contact with adhesive , must be at or below the Tg of the adhesive so that adhesion at the point of contact between the matrix and the adhesive is reduced. For this purpose, as the adhesive itself is likely to be above Tg, it would be desirable to have the matrix below Tg for at least 2, 5 or at least 10Ό so that the adhesive itself is cooled by contact. It is also desirable to cool the adhesive before contacting the matrix to reduce the difference in temperature between the cooled matrix and the adhesive.

[00105] After the coolant flows into matrix head 702 through channel 710, a preferred design would have the coolant flow path extending completely beyond the edge of the cut surface 720, so that the effect The cooling system will extend more efficiently to the most complete limits of the cutting surface. This is shown in

Petition 870180036999, of 05/04/2018, p. 75/87

71/71 figure 7 through the inversion point 714 in the flow path being beyond the end of the cutting surface 720. The flow path of the coolant then continues to pass out of the die head 702 through the ventilation channel 712. The coolant is then returned to an area to be cooled again and then returned to flow path 710.

[00106] The previous descriptions provided precepts that enable the practice of a generic invention. The descriptions are considered to be exemplary of generic concepts and not limitations for the specific modalities of the examples. Those skilled in the art, upon reading this specification, will be able to practice the invention widely and will realize that alternative structures, method steps and materials will carry out the purposes and precepts of the invention and that the following claims are intended to cover the full breadth of the invention. revealed invention.
