Abstract

The invention relates to a process for making a woven label with data on at least one side. To this end, a fabric is first produced to which the data to be shown on the label are applied during weaving or later. A cut is made at the boundaries between these longitudinal fabric regions which divides the fabric with into strips which form a continuous label strip. Said strip is cut off into individual labels which can then be secured to an item. To obtain a forgery-proof label it is proposed to coat its data-less face evenly with a polymer emulsion. A blocking foil with a holographic design is laminated on the polymer layer obtained by pressure and heat. This provides a forgery-proof fabric-foil combination which can finally be cut into strips of labels.

Description

Method of making a woven, tamper evident label

The invention relates to a method for producing a woven label according to the type specified in the preamble of claim 1. The label has the function of identifying the goods to be equipped with the desired data and / or emblems. Such data can be more detailed information about the type and quality of the goods, e.g. B. specify the sizes, the article number, the country of origin of the goods or the like. In this case one speaks of a "goods label". In addition or instead, information about the manufacturer or the dealer of the goods can also be given on a label. Then there is a so-called "company label".

The following method is already known (DE-OS 39 10 218). In order to produce inexpensive labels, these are first produced in multiple repetitions as wide fabrics with a family of fabric zones running in the longitudinal direction of the fabric, which correspond to the width of the later label. In each tissue zone, during weaving or later, e.g. B. by printing on the fabric, the aforementioned data of the label continuously applied. In a further process step, the wide fabric is then cut into a group of strips, in each case along a boundary line between two adjacent fabric zones. Each strip then forms a continuous label tape with repetitive data from the individual labels. Such a label tape can then be cut to length in the individual labels. The individual labels obtained in this way are ultimately identified by the

ORIGINAL DOCUMENTS drawing goods attached, where necessary, they are folded beforehand and then attached as a loop. The attachment is preferably done by sewing, but can also in other ways, for. B. be performed by gluing.

An important function of the labels is to make the type and origin known, which is why company emblems or protected brands are also used as data. There are famous brands. After affixing a label with such marks to a product, the buyer of this product expresses particular appreciation. The brand owners therefore pay attention to the exclusivity of the use of the labels so marked. In order not to disappoint customers' expectations, the manufacturer or retailer pays attention to a constant, high quality of the goods that carry such labels. This effort results in a correspondingly high price of the goods.

However, there are product pirates who try to upgrade cheap imitations of known goods by illegally affixing labels with famous brands and thus benefit from the popularity of selling their imitations. This not only leads to market confusion, but also to considerable damage for the authorized label user if, for example, B. the customer sees his expectations changed as a result of reduced quality or the lifespan of the imitations and this incorrectly charges the authorized user. The legitimate trademark owner is therefore very interested in ensuring that only the labels that he controls are affixed to the goods that he manufactures or approves. Unauthorized third parties are to be largely prevented from counterfeiting.

In the case of non-woven labels (DE-OS 41 10 147) it is known to provide the label material with a metal layer, in the top of which a hologram visible from the outside is arranged. For this purpose, a cover film, which has the metal layer with the hologram, is glued on the underside to the top of a label material. In order to be able to attach the label to objects by gluing, a layer of pressure-sensitive adhesive is applied to the underside of the label material. From this it is not clear how weave labels can be made to be error-proof. The invention is based on the new objective to develop a method for producing labels of the type specified in the preamble of claim 1, which makes the imitation of labels impossible, but at least very difficult. This is achieved according to the invention by the method step specified in the characterizing part of claim 1, which have the following special meaning.

The invention assumes that, in addition to the data identifying the goods, which are generally formed on one side of the label, a label also has other areas which have hitherto remained unused, such as the opposite side of the label, and has recognized that these previously unused areas can be used as carriers for special labeling agents. Unauthorized persons should no longer be able to imitate these labeling means, or at least only in a manner that is clearly recognizable as counterfeiting. For this purpose, the invention proposes to apply a special stamping film with a holographic design to the generally data-free flat side of a label which cannot be imitated and which cannot be detached from the label again without being destroyed. For a viewer of the label, this holographic effect primarily affects itself through a depth effect which, depending on the incidence of light and / or the direction of view, changes the design of the film and, like a prism, causes the rainbow to shimmer in different colors.

To this end, the invention uses the multi-stage method specified in the characterizing part of claim 1, which leads to a special woven-foal composite from which the label according to the invention is produced as a cut product. The polymer emulsion used here consists of a plastic dispersion in an emulsion. The holographic flat side gives the label a largely error-proof character. The method according to the invention increases the cost of producing the labels only insignificantly, but brings the great advantage of being inimitable by unauthorized persons. With the invention, one thus obtains labels which, although still simply manufactured as a fabric, can be provided with further data and fastened if necessary, but can now be copied just as difficultly as credit cards or bank notes. Are goods with the inventive marked label, both the manufacturer or the dealer as well as the customer of the goods can immediately recognize from the holographic design on the label whether it is an original or a counterfeit. It is of course possible to provide a label produced according to the invention exclusively with the holographic design and to dispense with further information which can be applied by printing or the like. This further data could be arranged on a further label not produced according to the invention.

Further measures of the method and the advantages of the method and the label produced thereafter can be found in the subclaims, the following description and the drawings. The method according to the invention and the label obtained thereby are shown in an exemplary embodiment in the drawings. Show it:

1, a shoe as an example of a product drawn with a label according to the invention,

2 in large enlargement and in longitudinal section a section of a wide fabric that has passed through the first sub-steps of the method according to the invention,

3 in a sectional view corresponding to FIG. 2, the raw product obtained after a further process step,

4 shows a schematic, perspective representation of the wide fabric in the full train of various successive process steps,

5 and 6, in enlargement, the front view and the rear view of a band section which is obtained with the method of FIG. 4 and

7, in an enlarged perspective illustration, a partial piece of a product with a label attached to it according to the invention. Various labels 11, 12 can be used to identify a product 10, for example the shoe shown in FIG. 1. The one designed in the form of a loop label 11 contains typically alpha ^¬ numerical information on the quality, size, Item no., Origin country ^¬ od. Like. The product under 10. This is a so-unnamed "Goods label". The data 14 are applied to both outer sides of the loop. It goes without saying that a product 10 of any kind could be provided with such a label 11, for example items of clothing, such as shirts, jackets, gloves or laundry, such as towels or the like.

In some cases, a company emblem 13 or a protected trademark is not attached to the product label 11 itself, but is provided on a so-called “company label” 12 that is separate from it. Such emblems 13 or logos can also be provided together with the data 14 on a common label 11. The label 1 1 can also be designed as a flag attached only on one side.

To produce such a label 11, a broad weave 15 is used, for which purpose it is expedient to use meltable thread material. The wide fabric is made in the form of an atlas or satin on a loom. This wide fabric 15 is then fed to mechanical finishing work, which is referred to as "friction". The wide fabric 15 passes through a calender in the slightly moist state, which creates a joint between a heated hard steel roller and a soft counter roller. A heated steel roller rests on one flat side 16 of the sectional view of FIG. 2 and runs at a higher peripheral speed than the elastic counter-roller resting on the opposite flat side 17 and therefore grinds. With this friction, the fabric fibers are ground completely smooth on the first-mentioned flat side 16 and the fabric receives an intense shine there. This grinding track is indicated by dashes in FIG. 2 instead of the original flat side 16 of the fabric and is intended to illustrate the chintz character 18 which arises there. The wide fabric 1 5 can then be dyed if necessary and, in order to increase its stability, be suitably equipped, e.g. B. be impregnated with acrylic resins. A polymer emulsion 19 which can be seen in FIG. 2 is then applied to the flat side 17 opposite in the chintz side 18. This

Polymer emulsion 19 contains thermoplastic material and is

2 applied in moderation, preferably in an amount of 80 g per m. This is expediently carried out in a screen printing process, with all tissue pores being closed. However, the emulsion should penetrate the tissue as little as possible. The polymer coating 19 then dries, which is favored by the action of heat. Then the coating 19 cools down and forms a solid polymer layer with the wide fabric 15, which produces an intermediate product 29 shown in FIG. 2.

The dimension of the wide fabric 15 determines the width of the intermediate product 29, which can be between 1 to 1.5 m. In the next process stage, the intermediate product 29 is expediently first slowly cut into handy partial webs of approximately 22 cm, of which FIG. 4 schematically shows a piece of such a partial web 25. This division of the wide fabric 15 is expediently carried out by hot cutting, using heated knives or the like. For this reason, as already mentioned at the beginning, it is advisable to use fusible material as the thread material of the fabric 15.

As can be seen from FIG. 4, a special stamping film 20, which can consist of polyester, is then laminated onto the partial web 25 of the slurry thus obtained. This stamping film 20 is provided with a holographic design which, depending on the incidence of light and / or the viewing direction, has a different depth effect and is distinguished by an attractive rainbow play of colors. Prismatic effects occur. In any case, the design changes in a characteristic, inimitable manner depending on the direction of the gaze. Such holographic effects are known per se in credit cards. This stamping film 20 is applied to the polymer coating 19 by the action of heat and pressure. It can be heated to approx. 170 and act at a pressure of 4 bar. After the subsequent cooling, the polymer layer 19 solidifies again and a firm connection is formed from the intermediate product 29 and the pre-film 20, namely the special woven-foam composite 30 that can be seen from the enlarged sectional view of FIG. 3. As can be seen from FIG. 4, this particular composite 30 is finally divided into a group of strips 22 by cutting in the longitudinal direction. These separations 23 are made by cold cutting between defined, longitudinally extending tissue zones, which define the later label width. Ultrasonic is preferably used for cold cutting. These strips 22, like the preceding composite 30, have a previously mentioned chintz side 18, which is directed downward in FIG. 3, while the opposite flat side 27 bears the front side of the applied stamping film 20. 4, the composite 30 is shown in a mirror-image manner, according to which the chintz side 18 points upwards.

Then, as can be seen from FIG. 4, each of the strips 22 is subjected to a printing process 24 which can either be carried out by the manufacturer himself or later by the customer. The printing process 24 takes place on the chintz side 18 pointing upward in FIG. 4, specifically in one color or multi-color. This creates from each of the strips 23 initially a label tape 21 with continuous, repeating data 19. By cutting the label tape 21 at the transitions 28 between data belonging to adjacent labels 14, the label tape 21 is divided into individual labels 11. This sectional position is illustrated in FIG. 4 by the direction arrow 26. The individual labels 11 have, according to FIG. 5, a front side 18 provided with data 14 and, according to FIG. 6, a rear side 27 provided with the special holographic design mentioned. The label 11 is now for affixing to a product 10 suitable.

Fig. 7 shows one way of connection. In this case the label 1 1 is used in the form of a loop. For this purpose, the label is folded around a central transverse axis 31 indicated by dash-dotted lines in FIGS. 5 and 6, so that the two loop legs 32 shown in FIG. 7 are formed. The transversely folded label is attached to a product with its two free leg ends 33 via a seam 34 or the like. The transverse folding takes place in such a way that the face 18 of the label provided with data 14 comes to lie on the outside. From the outside, however, the specially designed film side 27 of the label 11 can be seen in the inside of the loop. The described holographic depth effects and play of colors are therefore Sufficiently recognizable inside the loop. The loop between the two legs 32 opens particularly well due to the inside of the stamping film 20. The film 21 counteracts a kink on the apex and spreads the loop. The interior of the opening loop is therefore well suited for viewing the film side 27 there.

Instead of a label 11 attached in the form of a loop, a label produced by the method according to the invention could of course also be attached as a simple acceptance flag, that is to say only at one end. Then both the printed face 18 and the holographic film side 27 are fully visible. Furthermore, it would be possible to use the holographic film side 27 as the display side and, if necessary, also to print it. The applied stamping film 20 did not need to extend over the full area, but could also only be provided in zones. It would thus be possible to provide the described film side 27 in a first zone and a second zone serving as a print on the same flat side of a label. In this case, the measure according to the invention could also be used for the second label 12 in FIG. 1, which is attached to the goods 10 with its one rear flat side, which then remains invisible to the viewer. The label 12 could also be attached to the goods 10 only in places, which is why the rear surface side can then still be checked.

The data 14 need not be generated by a printing process 24, but could already be made during the weaving in the original wide weave 15 using appropriate colored threads, e.g. B. a figure shot, incorporated. This then results in tissue zones running in tissue direction, between the boundary lines of which the above-mentioned separating cuts 23 between the individual label strips 21 are then carried out.

It would also be possible to carry out the printing 24 before the cold cutting 23 of the strips 22, namely in the region of the still connected tissue-foene composite 30 or the partial tissue web 25 from FIG. 4. Finally, as already possible was mentioned at the beginning, an additional printing or attachment of further data is dispensed with. A tamper-evident label is already obtained when the label with the holographic design. The remaining data 14 used to identify the goods 10 could be provided on a separate other label 12 instead of the label 11 which is relevant here, as shown in FIG. 1.
