Description

The present invention relates to a method and an apparatus for Manufacture of laminate labels according to the preambles of claims 1 and 9.

In practice, laminate labels have so far been produced in such a way that a carrier material web with an endless label web arranged thereon Laminate film application station is fed into the transparent laminate film web is applied to the carrier material web in such a way that the Label web sandwiched between the carrier material web and the laminate film web is recorded. Since the side of the Laminate film web is provided with an adhesive coating, then adheres the laminate film firmly on the carrier material. Then the laminate film web, the laminate label web of the label web and the carrier material web a separation station in the form of a punching station, in which from the Laminate label web by means of a rotating punch cylinder individual labels be cut out. For this purpose, this punch cylinder has on its cylinder peripheral wall at least one of the shape or contour of the actual label appropriate knife contour.

This procedure in the prior art has proven disadvantageous in that that for different label sizes, but also for different ones Different punching cylinders can be used for label shapes or contours have to. Since such punch cylinders are relatively expensive to manufacture are, this increases the cost of an apparatus for producing Laminate labels. In addition, when changing from one type of label to another to one of this type of label in terms of size and / or shape distinguishing label type of a considerable assembly effort.

In addition, the known laminate labels thus produced have the Disadvantage on that over the edge of the object to be labeled applied dirt and / or moisture between the actual labels Label and the laminate film can penetrate because the laminate film with the Label material is flush at the edge. Such laminate labels for example in machines and the like. in a dirty and / or used in a humid atmosphere, they can be illegible or detach from the machine.

GB-A-2 274 268 describes a method and a device at the beginning mentioned type. In the known method after the application of the Laminate film web on the carrier material web already provided with the labels the resulting laminate label web is fed to a punching station in which individual labels are punched out of the laminate label web. Here, however does not punch through the carrier material web, so that the punched out Laminate labels on the continuous web of carrier material remain. The rest of the laminate film web is removed by the Laminate labels and the backing material strip are peeled off and placed on a separate one intended roll wound.

EP-A-0 212 919 also describes a method for producing labels as well as these labels themselves. In this known manufacturing process onto the carrier material web, which is provided with an adhesive layer on one side, individual, folded sheets of paper applied as a result of the on the Adhere the backing material to the existing adhesive layer there. Then will one on the carrier material web and the individual labels arranged on it Laminate film web applied, the width of the width of the carrier material web equivalent.

It is an object of the present invention, a method and an apparatus to create of the type mentioned, with which in terms of shape and Size different laminate labels can be easily produced.

With regard to the method, the above task is characterized by the features of Claim 1 solved. In contrast to the prior art, where a laminate label in a single step from the laminate film web, the label web and the existing laminate label web are punched out is, in the inventive method in a first step Labels individually, with gaps between the labels in Longitudinal direction of the carrier material web arranged on this. Then in a second step after the preferably transparent and also preferably an adhesive coating on its side facing the carrier material web having laminate film applied to the substrate web a single segment of the thus formed laminate label web one essentially transverse to the direction of advance of the label web Cut severed. The laminate label web can then be made from this segment the actual label by peeling off the backing material from the label and the laminate film can be obtained.

This procedure has the advantage that not for different labels Various punching or cutting tools must be kept ready. Rather, the carrier material web, which is preferably wound into a roll is in the first step with labels of the appropriate shape and size be "populated". This first step can basically be done in the device for Manufacture of the laminate label itself. However, it is also possible that this first step in a specially designed placement device is carried out separately from the the laminate film application station as well as the device for manufacturing comprising the separation station the laminate label is arranged. Since the carrier material web is often not the user of the manufacturing device for laminate labels is produced himself, the user of the device only needs roles with regard to shape and size procure different labels and have them ready for different labels to be able to manufacture. In addition, when changing from one to the other Label type to a different from this label type in terms of shape and size distinctive label type no assembly process to replace any tools, such as the prior art regarding Stamping cylinder is the case, but it only needs to be the role of the web of carrier material with the other labels are inserted into the manufacturing device. Furthermore, the downtimes of the manufacturing device are shortened as a result a complicated disassembly and assembly process for the punch cylinder is eliminated, but, as has already been explained, only the carrier material web or whose role needs to be changed.

Basically, it is conceivable that the cut to separate the individual Segments of the laminate label web precisely along the two edges of the label is executed, which is essentially transverse to the longitudinal extent of the carrier material web run. Here are then to separate a single segment Laminate label web two cuts necessary in the respective space must be introduced. In contrast, only a single cut, preferably in the middle between two successive labels in the space the number of steps required is reduced to obtain a segment or a laminate label. Secondly towered over thereby the laminate film the label at least on these two edges. This Supernatant can be used to improve not only the laminate label to be able to attach the item to be labeled with it, but also since the film adheres closely to the object, the penetration of dirt and / or to prevent moisture between the laminate film and the label.

In order to increase the adhesion of the label to the object to be labeled, can also be provided that the label on the to the carrier material facing side is provided with an adhesive or adhesive coating, so is designed so that the label is fixed on the carrier material, but without can be detached from the carrier material. So that the laminate film and that preferably provided with an adhesive coating when removing the label a label from a label segment from the carrier material without further notice can solve, can also be provided that the carrier material with a Non-stick coating, preferably a silicone coating. in this connection should this non-stick coating be designed so that the laminate film and Labels adhere to the carrier material to a certain degree, but when Do not detach any components of the carrier material on the laminate film and / or the Stick etiquette.

If the labels are asymmetrical to the longitudinal axis of the backing material web If this is arranged, a grip edge is created which is used to detach an individual Laminate labels from a segment of the segment obtained by the separation station Laminate label web and attaching the laminate label to the relieved labeling object. In particular, the laminate label not damaged and / or the adhesive coating of the laminate film or the label is made unusable by touching it with, for example, the hand.

If a sheet of laminate film is placed on the individual labels Carrier material web applied, the width (i.e. the direction perpendicular to Longitudinal extension of the carrier material web or the laminate film web in the plane the web) is smaller than the width of the carrier material web, so that a Material savings in the laminate film can be achieved, for example, because existing grip edge on the carrier material web not from the laminate film needs to be covered.

To make it easier to remove a laminate label from the backing, In the area of the label, the carrier material web can be punched out be provided. To put a laminate label on an item to be labeled To be able to apply, the punching of the laminate label is then first peeled off and then the remaining carrier material.

In order to make it easier to remove the punched-out section, that the label with an approximately in the longitudinal direction of the carrier material web and perforation arranged in the region of an edge is provided.

It has proven advantageous for control of the disconnection station when the Labels with equal gaps on the backing material web to be ordered.

The laminate film web can simply be placed on the carrier material web. For particularly good adhesion of the laminate film web to the backing material web To achieve, it has also proven to be advantageous if the laminate film web rolled onto the substrate web in the laminate film application station becomes.

This enables a particularly flexible use of the method according to the invention achieve that the labels arranged on the substrate web before Feed to the laminate film application station, preferably in the device be printed to produce the laminate labels.

With regard to the device, the above object is achieved by the features of Claim 9 solved. By providing a substantially transverse to Make the feed direction of the label web running separating cut Cutting device is not required in the device according to the invention punch cylinder to be adapted to the respective label. Therefore, the invention does not apply Manufacturing device also any disassembly and assembly work for such cylinders.

The cutting device can be formed by a wide variety of arrangements his. The cutting device preferably has at least one perpendicular to the Surface area of the label web reversible movable knife on that the top or bottom of the label web can be arranged. That knife interacts with a counter knife, which may also be movable, which then is arranged either on the bottom or top of the label web.

To order the labels as desired by the individual user of the manufacturing device To be able to print individually, it can also be provided that in Feed direction of the carrier material web in front of the laminate film application station Printing station with one or more print heads is provided.

Around the laminate film bubble-free and well durable on the carrier material web To be able to apply, it can further be provided that the laminate film application station one or more are essentially the width of the laminate film web extending pressure rollers.

As already pointed out above, is due to the edge protruding over the carrier material of the finished label the penetration of dirt and / or moisture between the laminate film Laminate film and the label prevented. At the same time, the protruding edge the laminate film for attaching the label to the object to be labeled be used. This also gives the possibility that on the side of the label facing away from the laminate film no additional Adhesive or adhesive layer must be applied. If such a liability or Adhesive layer on the side of the label facing away from the laminate film provided, the protruding edge of the laminate film also serves as additional protection against unauthorized detachment of the label from the labeling object. Since the label itself sticks to the object, when the laminate film is peeled off from the adhesive label, parts of the Print-bearing layer of the label with peeled off. With the well-known Laminate labels where the laminate film is flush with the edge of the label closes this, on the other hand, the label can be removed by pulling the adhesive side without Damage can be removed.

a plan view of a carrier material web used in the device according to FIG. 1 with individual labels arranged thereon; and

Figure 3

a plan view of a segment of a laminate label according to the invention.

A device 10 for producing laminate labels is shown schematically in FIG LE (see Fig. 3) reproduced. That explained in more detail below The housing surrounding individual assemblies of the device 10 is shown in FIG. 1 partially removed. Only that, in relation to FIG. 1, is essentially vertical extending rear wall 10a, which, also with reference to FIG. 1, extends vertically extending right side wall 10b and that, also in turn on figure 1, horizontally extending floor 10c are shown.

The manufacturing device 10 comprises a supply station 20 for receiving one a supply roll 22 rolled up laminate film web LB, a laminate film application station 30 and a separation station 40.

The storage station 20 for the laminate film roll 22 is essentially a Shaft 24 rotatably supported in the vertical wall 10a, on which the supply roll 22 can be pushed on and by a locking device, not shown is axially lockable. From the supply roll 22 is the laminate film web LB deducted in the direction of arrow X and a deflection roller 26 to the Laminate film application station 30 out.

In the laminate film application station 30, the laminate film web LB is placed on the based on Figure 1, substantially horizontally in the direction of arrow Y in Figure 1 supplied carrier material web TB (i.e., based on Figure 1, from right to left) applied. The carrier material web TB, as shown in FIG emerges through an opening 10ba present in the right side wall 10b led into the interior of the manufacturing device 10. Of course there is also the possibility of a corresponding supply roll for the carrier material web TB in To be provided inside the manufacturing device 10.

As can be seen from FIG. 2, the carrier material web TB has a plurality of individual ones Longitudinal direction of the carrier material web TB while maintaining gaps Z approximately the same size one behind the other arranged labels E. The labels E are asymmetrical to the longitudinal axis of the carrier material web TB on this arranged, i.e. they are closer to one longitudinal edge than to the other Longitudinal edge of the substrate web TB aligned.

The labels E have one on their side facing the carrier material web TB Adhesive coating, whereas the carrier material web TB on the label E facing side is provided with a non-stick coating that is sticky the label E on the carrier material web TB prevents, but still adheres enables the label E on the carrier material web TB, so that the label E on the carrier material web TB are fixed in their position.

As can further be seen from FIGS. 2 and 3, the carrier material web TB in Area of each label E has a punch-out A that is smaller than the label E itself and which is arranged in relation to the label E so that it has three Edge sides of the label E protrude beyond this. This punching A makes it easier pulling off the laminate label LE (see FIG. 3), since the material of the punching A first peeled off the LE laminate label and then that remaining carrier material of the carrier material web TB without further ado Laminate label LE can be removed.

Finally, it can be seen from Figure 2 that each label E on the im The area of the punched-out A longitudinal edge is essentially parallel has perforation P running to the longitudinal edge.

In the laminate film application station 30, the preferably transparent and on its side facing the carrier material web TB with an adhesive or Laminate film web LB provided with adhesive coating initially by means of a Guide roller 32 and then by means of a laminating roller 34 on the Carrier material web TB applied. As can be seen from Figure 3, the Laminate film web LB has a smaller width than the carrier material web TB. The The width of the laminate film web LB is with the double arrow bl and the width of the Carrier material web marked with the double arrow bt. At the same time, the Laminate film web LB flush to the edge of the carrier material web TB on this applied to which the label E has also moved closer. This creates a gripping edge GR, which is used to attach a single LE laminate label to a object to be labeled easier.

As can also be seen from FIG. 3, the width b 1 of the laminate films LB is selected such that, when it is flush, it lies on the one longitudinal edge of the carrier material web TB (ie with its left edge with reference to FIG. 3) with the outside of the label E. Edge of the punched-out A is flush (ie, the right one of the punched-out A, based on FIG. 3).
After the laminating film web LB has been laminated on by the laminating roller 34, the label web EB is produced, which is then fed to the separation station 40. In the separation station 40, individual segments S of the label web EB (cf. FIG. 3) are separated from the label web EB by means of a cut which runs essentially transversely to the longitudinal extent of the label web EB and is introduced into the intermediate spaces Z. This cut is carried out by a knife (not shown further), which extends essentially transversely to the longitudinal extent of the label web EB and is reversible in the vertical direction, based on FIG. 1. This knife can be designed as an upper or lower knife. It interacts with a counter knife which is arranged on the top and bottom of the label web EB and which in turn can be arranged to be movable but also stationary. The separating station 40 separates the individual segments which, based on FIG. 1, fall to the left of the separating station 40 into a corresponding collecting device, not shown.

In the production of a laminate label LE according to the invention is as follows The procedure:

First, the carrier material web TB in a possibly separate from the Manufacturing device 10 according to the invention arranged the individual Labels E in the desired shape and size that already have the perforation P can wear, applied in such a way that in the longitudinal direction of the carrier material web TB the spaces Z are present. Afterwards, or before, the Carrier material web TB are provided with the punched-out A.

The carrier material web TB thus prepared then becomes the laminate film application station 30 supplied, in which the laminate film web LB evenly on the Carrier material web TB is applied. Then the carrier material web TB with the laminate film web LB as the label web EB of the separating device 40 fed, and there individual segments S of the label web EB from this separated. This is done by an essentially transverse to the longitudinal extent the carrier material web TB and in the spaces Z between the individual labels E cut. You can then use the separated label segments S by means of the individual laminate labels LE Pull off the carrier material in the area of the punching A and then through Peeling off the rest of the carrier material on the object to be labeled be stuck on. The segment can be held on the grip edge GR be so that it is not dirty and the adhesive coating of the label E and the laminate film L becomes unusable. Because the cut in the space Z is executed and the carrier material completely from the label E and of the laminate film, the laminate film projects beyond the label E, as shown in FIG. 3 is shown. This makes the LE laminate label particularly secure without the Danger of ingress of dirt and or moisture between the Laminate film and the label E on an object to be labeled be attached.
