Abstract

The reeled band carries partially adhesive labels (2) for the automatic placing of the labels on any kind of object. Each label comprises on its adhesive surface (3B) a patch (5,6). The patch issues from a continuous band and is located opposite a solid continuous portion of the transport belt (4). The patch face (5A,6A) opposite the transport belt has a non-adhesive face constituting a gripping zone for repositioning the label on any support. Independent claims are included for an adhesive label and a method of obtaining the label carrying band.

Description

The present invention relates to a wound label holder strip at least partially adhesive for installation automated labeling of nature objects any label, at least partially adhesive from such a tape as well as a process for obtaining wound tape.

The present invention relates to the general field of so-called easy open / close adhesive labels, these labels generally being adhered to sachet type packaging and used for closure of these by holding, generally in position folded, from the edges of the opening of the sachet.

To facilitate gripping or gripping, these labels are usually provided with a tab non-adhesive grip. This tab consists of a insert on the adhesive part of the label, the free side of the yoke, i.e. the opposite side to the side adhered to the adhesive side of the label being non-adhesive. So far, this yoke has come from the label conveyor belt. Indeed, the labels cut from an adhesive strip are, for their storage and transport or for their installation, adhered by their adhesive side to a generally silicone strip called a conveyor belt. This conveyor belt peelable is removed when the label is placed on its final support, for example on a sachet. The laying of these labels is usually automated. The band conveyor is therefore a continuous belt carrying a multiple labels. This strip is stretched to inside a laying machine so that the labels are, during the tape running conveyor which follows a predetermined trajectory, automatically peeled off from said strip and then laid by licking or by means of suction cups or the like devices on the support, such as a bag, scrolling below of said label.

The disadvantage of sparing the insert reported on the adhesive part of the label in the conveyor belt of the label is linked to the weakening of the tape resulting conveyor. Indeed, because the conveyor belt is provided with a plurality of openings each time corresponding to the cut panel, this risk band, during a tension necessary for the installation of the label, to break, especially when the the label is applied at a high rate. Through elsewhere, because the yoke comes from the strip conveyor and that the latter is generally silicone to facilitate removal of the label from the tape, it results, during the fitting of the label or the opening / closing use of the latter, a detachment from the label yoke. This induces a high percentage of non-compliance with the use of the because of the absence of the tab that has been removed from unintentionally when laying either is eliminated on first use. For all these reasons, this solution is today unsatisfactory.

Another solution has also been developed for set up an input or grip tab at the level of the adhesive part of the label. To this end, a part of the label adhesive is neutralized by deposit of a neutralizing varnish. However, the downside major of this technique is that over time, the part neutralized tends to become sticky or sticky depending on the thickness of the deposit, the climate and the temperature room. This results in an absence of comfort of the user over time.

We also know multilayer labels repositionable as illustrated in particular by international applications WO 01 98073, WO 95 28728, WO 01 88886 and WO 00 64764.

An object of the present invention is therefore to propose a adhesive label as well as a wound label holder strip adhesives whose designs allow the use of a conveyor belt continues to the exclusion of any cut in the said strip so as to maintain a high mechanical resistance of this strip conveyor.

Another object of the present invention is to provide a adhesive label and a wound label strip adhesive whose designs allow obtaining a yoke stably positioned on the part adhesive label, any risk of peeling of this yoke being eliminated.

Another object of the present invention is to provide a adhesive label whose design allows versatility of the at least partially adhesive face of said label depending on the nature of the inserts reported on said label so as to constitute indifferently, at the level of the inserts, areas of input, repositioning or other of the label.

To this end, the invention relates to a wound strip at least partially adhesive label holders for the automated labeling of nature objects any label, each label having, on its face adhesive, at least one yoke, characterized in that the yoke from a continuous strip is arranged in look of a full uncut continuous portion of the conveyor belt, the face of this yoke facing of the conveyor belt being a weak side adhesive or non-adhesive constituting a grip area or label repositioning, especially in the state adhered to the label on any support.

Thanks to the design of the conveyor belt, free of any cutout in its area opposite the yoke, this results in a conveyor belt the mechanical resistance is not altered. Therefore, a automated labeling can be considered without problem.

The invention also relates to a label at least partially adhesive generally from a strip wound label holder of the aforementioned type, characterized in what it comprises, on its adhesive face, at least one yoke permanently adhered to said face.

The invention also relates to a label at least partially adhesive generally from a strip wound label holder of the aforementioned type, characterized in what it has, on its adhesive side, at least two inserts of a different nature.

The invention also relates to a process for obtaining at least partially wound label strip adhesive, this strip being formed of a complex of at least at least two leaves of different nature, one dorsal mainly for the transport of labels, the other front at least partially adhesive and in which the label is cut or cut except for any cut in the dorsal, characterized in that, when scrolling of the complex strip, we separate at least partially dorsal and frontal, rewinding at least partially one of the two, we apply on the part scrolling at least one continuous or discontinuous mask from of a continuous strip to form, in the cut state of the label, a non-adhesive grip area the label or a weakly adhesive area of repositioning of the label, we gather the part scrolling with an additional part to reform a dorsal / frontal complex.

The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:

FIG. 1 represents a schematic view of an at least partially adhesive label according to the invention, this label being provided with two inserts of different nature;

FIG. 2 schematically represents an installation for implementing a process for obtaining a wound strip according to the invention, the front of this strip being provided with a yoke and

FIG. 3 represents a schematic front view of another installation for obtaining a wound label-carrying strip according to the invention, the front of the strip comprising two inserts.

As mentioned above, the subject of the invention is a label 2 at least partially adhesive as well as the strip 1 wound from which it comes. These labels partially adhesive are said to be open / close easy. To this end, these labels include, on their adhesive side, at least one panel 5, 6 adhered to permanently to said face. By "joined so permanent "means adhesion as it is necessary to tear the yoke 5, 6 and / or the face 3B adhesive label 2 to separate the yoke 5, 6 of the adhesive side 3B. Figure 1 illustrates an example of creation of a label 2 at least partially adhesive according to the invention.

This label 2 is made up, before adhesion to a support of any kind, of a complex of at least two sheets of different separable nature, one 4 dorsal mainly for the storage and / or transport of label 2, the other 3 front at least partially adhesive. This front sheet 3 consists of a side 3A visible information carrier and side 3B adhesive not visible. This adhesive side 3B is at least partially covered by at least one, of preferably at least two panels 5, 6, the faces of which 5A, 6A opposite to those adhered to the adhesive side 3B of the front are non-adhesive or weakly adhesive for constitute a zone 5A, 6A for taking or repositioning of the front 3 of the label 2 on any support. Thus, in the example shown, zone 5A of the yoke 5 constitutes a non-adhesive face while the area shown in 6A in Figure 1 is an area weakly adhesive, i.e. an area whose adhesion characteristics are lower than those of the adhesive side 3B of the label 2 to allow a repositioning of label 2 on the support on which she is a member. So, such a label can be used for example to close a bag. The part 3B is permanently fixed to a wall by external example of the bag. Part 5A is used for handle the label without touching the adhesive. The part 6A is used to reposition the label and re-close the bag after a first opening. Thus, the adhesive 3B prevents any detachment untimely label of the sachet. Adhesive 6A allows label repositioning allowing multiple bag openings while zone 5A allows a grip of the label without the finger being in contact with a adhesive.

The conveyor belt 4 or back of the label is to him eliminated at the time of the installation of the frontal of the label on any medium. Generally, when the label has on its face 3B adhesive several panels, these are different nature. So, in the examples shown, the panels have characteristics different adhesion. Thus, the free faces 5A, 6A, corresponding to the faces not adhered to the adhesive side 3B of label 2 of inserts 5, 6, have different grip characteristics from yoke to another insofar as the face 5A free of yoke 5 is a non-adhesive area for gripping the label while the free face 6A of the yoke 6 is a weakly adhesive repositioning area of label, in particular in the adhered state of the label 2 on any support. This label thus forms a label 2 called easy opening / closing. These inserts 5, 6 can also be made in one different material. In the example shown in the figure 1, the inserts 5, 6 are adhered to the adhesive face 3B of label 2 by the adhesive 9 of label 2. Besides the causes each yoke 5, 6 to be adhered so permanent to the adhesive side 3B of the label and that this yoke may be different in nature from yoke to another, each yoke is further characterized by the fact that it consists of a cut out of a strip 7, 8 continues as illustrated by the manufacturing processes shown in Figures 2 and 3, which will be described in more detail detail below.

The label, as described above, is generally from a strip 1 wound label holder. This tape 1 wound label holder 2 at least partially adhesive, is again formed of a complex of at least two sheets 3, 4 of different nature, one dorsal 4 mainly for transporting labels 2, the other frontal 3 at least partially adhesive and in which label 2 is cut or cut except for any cut in the dorsal 4. Thus, the frontal 3 comprises, on its adhesive part 3B, at least one mask 5, 6 continuous or discontinuous from a band 7, 8 continues for form, in the cut-out state of the label 2, a zone 5A not grip adhesive or weakly adhesive area 6A for repositioning the front 3 of the label 2 to the state adhered from the frontal. The manufacture of such a wound strip is illustrated in Figures 2 and 3. The installation for manufacture of such a strip is generally constituted of take-up / take-up rollers represented by a symbol consisting of a circle and a point inside, as illustrated in Figures 2 and 3, rollers serving only to facilitate the scrolling of the bands, called passage rollers, pressure rollers represented by a round filled internally with a horizontal bar, tables made up of rollers and represented by a circle with vertical bars and tools inside of cutting represented in the form of circles with a cross to inside.

The method of manufacturing such label-holder wound tapes at least partially adhesive always rests on the same basic steps. Indeed, when scrolling a complex strip consisting of a frontal 3 and a dorsal 4 'we separate at least partially dorsal 4' and front 3 by partially rewinding at least one of the of them. We apply at least one continuous or discontinuous mask from a continuous strip for form, in the cut-out state of the label 2, a zone 5A not adhesive for gripping the label 2 or zone 6A weak adhesive label repositioning 2 then we bring the moving part together with a part complementary to reform a dorsal / frontal complex shown in 4, 3 in the figures. The tape can thus be stored before cutting the label or after cutting the label. In this second case, after re-training of the dorsal complex 4 / frontal 3, during the scrolling of this last, we cut in this frontal 3 the label 2 to the exclusion of any cut in the dorsal 4 and, parallel or after cutting, we rewind the strip 10 of scraps from the cutting of the front 3. This is called weeding. In the example shown in Figure 2, the strip 1 obtained is a strip whose front has a single yoke whose face free 5A is a non-adhesive side. As the Figure 2, in a first step, we separate the front 3 and the backbone 4 of the original complex. Then we incorporate a yoke 5 from a continuous strip 7. We take note that this yoke 5 is deposited on the front 3 by means of a rotating roller ensuring, parallel to the cutting of the yoke 5, the rewinding of the strip which is from this yoke 5. So, we cut and we put simultaneously the yoke 5 on the front 3. A once the yoke 5 has been deposited and adhered to the adhesive face 3B of the frontal 3, we can then re-apply a dorsal 4. In a subsequent station, a cutting tool ensures in the front 3 the label cutout 2. Here, the yoke is applied to the front as an element batchwise. A similar process could have been implemented by depositing a yoke in the form of a continuous element for example in the form of a strip. This solution is not possible only when the yoke extends from the end upstream towards the downstream end of said label taken from the direction of travel of the tape. Figure 3 illustrates a solution in which a band, and in particular the front 3 of the latter, has two panels shown in 5 and 6 in the figures. In this case, analogously, we first carry out a separation of the front 3 and the back 4 ', the back 4' being rewound on a spool. A yoke 6 is deposited on the adhesive portion 3B of the front 3. This yoke 6 is from a band 8 which scrolls under a rotary tool which simultaneously ensures the cutting and installation of said front panel. The rest of the strip 8 is rewound. This strip 8 is a weakly adhesive strip of so that the free face 6A of the yoke 6 deposited on the adhesive face 3B of the frontal 3 is a face weakly repositionable adhesive. In a stage next, a yoke 5 from a strip 7 is deposited adhesive. This yoke 5 is intended to constitute a label entry or gripping area. The face free 5A of this yoke is therefore a non-adhesive face. Finally, in a next step, we re-deposit a strip conveyor 4. Note again that for the removal of yoke 5, the cutting is carried out simultaneously and the fitting of the yoke by means of a rotary member under which the strip from which the yoke comes scrolls. A once the strip thus reconstituted, this can be wound and stored without cutting the label or labels can be cut immediately from said bandaged. This example is illustrated in Figure 3 where an extension cutting eliminates the strip 10 constituting the falls from the label cutout. So the band wound with 2 pre-cut adhesive labels. This wound strip can then be positioned on a labeling machine known per se.

The manufacturing processes illustrated above are of extremely easy to use and require relatively simple installations made up essentially rotary pressing elements, rewinder / unwinder, passage or cutting. It results in a simplification of the whole design such facilities.
