Abstract

The form (1) has a removable card (2) is integrated into it and is attached at least partly to the surrounding material at its outer (3) edge by bridge formed by a predetermined fracture line. In this line the material is thinner than the overall thickness of the form. Preferably the bridge is one layer making up the thickness of the form material, the remaining layers being cut through along the card edge and the bridge. In particular, the bridge layer is an inner layer and outer layers are separated along coincident cutting lines. The bridge may have a sawtooth shape or can form perforations. The card may be a self-adhesive label.

Description

Form with integrated card

TECHNICAL AREA

The present invention relates to a form with an integrated, removable card, wherein the form can be constructed in one layer, but in particular in multiple layers.

The cards can be cards that are practically ready in the form and only need to be removed. However, it can also be cards which are not in their final layer structure in the form but in several parts and which, for example, have to be finished by the user when they are removed, if necessary after personalization has been applied. Because this usually involves a folding process, cards of this type are also referred to as butterfly cards.

The cards can also be designed such that they initially have the properties of self-adhesive labels or self-adhesive labels can be produced from them, for example by peeling off a release paper. The cards can also be designed as so-called vignettes, which are intended to be glued behind a glass pane, whereby they are provided on their side facing the glass pane with specific, possibly individual information.

STATE OF THE ART

Forms with integrated cards of the aforementioned type are known, for example, from WO 95/20493 or EP-AI-0 733 490. In the known forms, a backing material is glued to the back of the primary form material, which comprises a backing layer and a peeling layer. The card is produced in the area of the carrier material by means of a stamping directly in the form, the stamping being carried out from the front of the form to the carrier layer of the carrier material. The advantage that can be achieved with this training and is based on the special properties of the peeling layer consists, above all, in that the card can be punched out in a web-free manner and completely. The peeling glue is set so that it essentially loses its stickiness when the card is removed.

Suitable peeling systems of this type can be implemented according to various principles, but they are all associated with a not inconsiderable effort in production and processing. The known peeling systems also show a release value behavior that is dependent on environmental conditions such as temperature and humidity and are therefore also not technologically easy to master.

In the case of the known forms, on the one hand the total thickness in the card area is kept small by including the primary form material in the card, but on the other hand the backing layer contributes significantly to this total thickness. With regard to the processing of the forms in printers, in particular in the single sheet method in laser printers, the smallest possible overall thickness in the card area is desirable. PRESENTATION OF THE INVENTION

The invention, as characterized in claim 1, solves the problem of specifying a form with an integrated, removable card, which works without Schälim and without a carrier layer, which is not part of the finished card. According to the invention, this is achieved by a form in which the card is connected to the material surrounding it at least partially along its outer edge (card edge) in the form via a bridge designed as a predetermined breaking line, the material thickness along the bridge being consistently less than the total thickness of the form is.

Preferred refinements and developments of the invention are specified in the dependent claims.

For example, the bridge is advantageously formed by an inner or an outer partial layer, with all remaining partial layers from one or both sides of the form along the bridge on the edge of the card e.g. are severed by punching. The bridge can also or alternatively be formed by a residual thickness between two cut lines that are attached from the two sides of the form and are congruent or at least substantially congruent.

With the above-mentioned designs, the desired holding value of the card in the form can be set well, namely purely geometrically via the depth of the incision or the incisions or the resulting residual thickness of the partial layer left intact, or via the residual thickness between two incisions made from both sides of the form . For example, a residual thickness in the range between 10μ and 50μ, in particular between 15μ and 25μ, has proven to be favorable, the optimum value depending on the type of material and / or being determined by the application. In particular, if the form is punched from both sides and thus provided with incisions along the edge of the card and the bridge, the card can be easily removed from, without the risk of the material breaking in as a predetermined breaking line other than along the bridge Remove the form.

The bridge can be formed evenly and without any bridges over its longitudinal extent, but also in a sawtooth shape or in the manner of a perforation with alternating cutting and web sections. In contrast to the "classic" perforation, however, the material is also cut at least partially in the web sections, so that only the aforementioned residual thickness is present in the area of the webs.

With such a structured or differentiated design of the bridge, the holding strength of the card in the form can be set even more precisely and finely and good results with regard to its removal can also be achieved if the bridge is arranged in an outer layer and the other sub-layers only from the latter Layer on the opposite side are severed.

Through additional film cover layers, on one or both sides on e.g. applied to a supporting paper layer, plasticized cards can be produced as in the prior art. Because of their rather unfavorable tear or tear properties compared to paper, however, the film layers are less suitable for forming the bridge. The bridge is therefore advantageously used e.g. formed in the load-bearing paper layer and the film cover layer / s along the bridge on the card edge completely severed.

If one would like to avoid cutting these layers on both sides in the case of double-sided film cover layers, one of them or a partial layer thereof must inevitably Training of the bridge can be used. By structuring the length of the bridge, as mentioned, in the manner of a perforation with very short webs, good results can also be achieved here with regard to the card being removed, while avoiding undesired tearing.

Using additional separating layers or additional separating layer material, butterfly cards, cards containing self-adhesive labels or vignettes can also be realized.

Since at least the backing layer and the peeling layer are omitted compared to the prior art, the cards can be written on the entire front and back even if they are still integrated in the form. If there are film cover layers, these can be treated specifically for the sake of being writable, i.e. e.g. be matted.

The present invention also relates to a method for producing the forms according to the invention of the type described above, which is characterized in accordance with claim 24 in that the form for generating the card is stamped on both sides at least partially congruently or at least essentially congruently from both sides along the edge of the card.

The double-sided punching can be carried out on individual forms as well as on endless webs in which the forms are still related. It can be carried out from both sides at the same time, but also in succession with respect to the two sides. The resulting requirements for register accuracy are basically manageable.

The concept according to the invention is largely independent of material and thickness. It works in a simple paper as well as in a complicated multilayer structure. In contrast to those based on the peeling principle, the card is taken from the forms according to the invention, despite the higher holding force, without a curl effect, since the card practically does not have to be bent when removed, but can simply be pushed through.

By eliminating the carrier material and peeling material, the manufacturing costs are reduced compared to the previously known forms.

Further refinements and advantages of the invention result from the following description of exemplary embodiments in conjunction with the accompanying drawings.

In Fig. 1, 1 designates a form shown only partially in supervision of its front and 2 a card integrated therein. The card edge is labeled 3. Adjacent to the card edge 3, a hole 4 is punched out, through which a section 5 of the card edge 3 is exposed. The hole 4 facilitates the removal of the card 2 and therefore forms a kind of removal aid.

2 to 6 show examples of possible layer structures of the form from FIG. 1 in section, the section being in each case taken along line A-A in FIG. 1.

In the example of Fig. 2, form 1 is constructed in one layer, i.e. it consists only of a paper layer 6. According to FIG. 2 a), it is punched along the card edge 3 both from the front of the form (punching line 7) and from the back of the form (punching line 8) down to the depth of an inner partial layer 9 . The two punching lines 7 and 8 are all-round, web-free and congruent. The sub-layer 9 forms a bridge designed as a predetermined breaking line along the card edge 3 between the two punching lines 7 and 8. This bridge can be destroyed and the card 2 can be removed from the form by pressing on the card surface or by grasping the card edge 5 in the area of the hole 4 punched out as a removal aid. 2 b) shows the form with card 2 detached.

The embodiment of FIG. 3 shows a multi-layered form, which, however, is based on the same principle as that of FIG. 2, that is to say the card 2 is also held in the plane of the form by an inner partial layer 9 of a paper layer 6. On the front and back, however, additional film cover layers 10 and 12 are glued to the paper layer 6 by means of adhesive layers 11 and 13. The two punchings 7 and 8 are through this additional layers and cut them completely along the edge of the card. This considerably simplifies the removal of the card and in particular ensures that the bridge formed by the continuous sub-layer 9 of the paper layer 6 tears only along the edge of the card in the desired manner. The tear edge between the two film cover layers will always be slightly frayed. With suitable training, however, this fraying is in the micro range, can only be seen in the magnification and is practically imperceptible by tactile means. On the other hand, the fraying is advantageous with regard to binding the adhesive exposed on the film edges. 3 b) shows the form 1 with the card 2 removed. The card removed can practically not be distinguished from a completely cut card according to the prior art.

The additional layers 10-13 can be made smaller in area than the paper layer 6. It is sufficient, as is indicated in FIG. 1 by the broken line 14, if they cover the area of the card 2 and, if appropriate, additionally the removal aid 4. However, in order to achieve a uniform thickness, they could also be laminated over the entire surface with the paper layer 6. A uniform thickness has a favorable effect on the stackability of the forms and their processing in single sheet printers.

In the embodiment of FIG. 4, the bridge over which the card 2 is held in the plane of the form is formed by a separate sub-layer 15 which is bonded to the paper layer 6, here on the rear side thereof, by means of a pressure-sensitive adhesive layer 16. Layer 15 is preferably a thin layer of paper. The two congruent punchings 7 and 8 are made up to layer 15. This embodiment makes it clear that the position and type of the non-punched and layer-forming sub-layer in the layer structure of the form is variable. 5 shows an embodiment with a first type of butterfly card. With otherwise the same structure as that of FIG. 3, a piece of a release material with a support layer 17 and a release coating 18 is inserted between the front cover layer 10 and the front pressure-sensitive adhesive layer 11, the latter facing the pressure-sensitive adhesive layer 11. Although the pressure-sensitive adhesive layer 11 is drawn with an uneven thickness for illustrative reasons, it can actually be of uniform thickness. In terms of area, the piece of separating material is somewhat smaller than the front cover layer 10 or

Pressure-sensitive adhesive layer 11 and only covers the area surrounded by the broken line 19 in FIG. 1, which also does not completely cover the area of card 2. In the zone of the card 2 designated 20, the cover layer material 10 is thereby glued directly to the surface 21 of the paper layer 6; on the other hand, the card edge 3 and the punching line 7 following it run outside the separating material. Otherwise, the separating material is completely severed by the punching line 7.

Due to the above-described design, the front film cover layer 10 together with the piece of separating material attached to it can be bent in the area of the card 2 and the surface 21 of the paper layer 6 e.g. partially exposed for individual labeling. The inscription can then be sealed by gluing the film cover layer 10 onto the paper surface 21. To do this, only the piece of release material has to be removed and the adhesive layer 11 has to be exposed.

The embodiment of FIG. 6 is also based on that of FIG. 3, only that additional sub-layers 22-26 are additionally provided on the rear film cover layer 12. The sub-layer 22 is a peel layer and the sub-layer 23 is, for example, a paper layer, which can be provided with a specific imprint. A pressure-sensitive adhesive layer 24 follows and finally a release material with a release coating 25 on a base layer 26.

With this structure, it is possible to remove the backing material 25/26 from the detached card 2 and to glue the card onto any surface 27 like a self-adhesive label by means of the adhesive layer 25 exposed on it. By separating the non-permanently set connection between the peeling layer 22 and the film cover layer 12, a free, non-self-adhesive card 2 ¹ with a structure corresponding to the example in FIG. 3 can still be obtained. The three layers 22-24 remain on the surface 27. Any labeling that may have been applied to layer 23 becomes visible. This is shown in Fig. 6b). The remaining part can serve, for example, as a control label 2 '' for the card 2 '. The peel layer 22 is preferably set such that it is no longer sticky after it has been separated from the film cover layer 12.

FIG. 7 shows, like FIG. 1, a top view of part of a form 1 according to the invention, the integrated card here, however, being a butterfly card of the second type or a vignette, which in form 1 is open in two areas 28 and 29 available.

A form according to FIG. 7 in an embodiment with an integrated butterfly card is first described with reference to FIG. 8. According to FIG. 8a), form 1 comprises a paper layer 30, to which a film cover layer 32 is glued on the back by means of a pressure-sensitive adhesive layer 31. A separating layer 33 is also inserted in the area 29 between the paper layer 30 and the pressure-sensitive adhesive layer 31. According to the exemplary embodiments described above, the form 1 is punched from both sides, the punching lines 34 and 35 along the outer edge 3 'of the two card parts (card edge in the form) in the areas 28 and 29 to the depth of a partial layer 36 of the paper layer 30 all-round, bridge-free and congruent are executed. Along the line 37 between the two areas 28 and 29, the form material is additionally punched from the front down to the depth of the pressure-sensitive adhesive layer 31 (punching line 38).

In the construction of Fig. 8, a e.g. Auxiliary card 39 which can be used as a coupon or control card can be removed from the area 29 of the form 1, the bridge formed by the partial layer 36 of the paper layer 30 being destroyed along the punched lines 34 and 35 in this area. As a result, the two layers 31 and 32 lying underneath in this area 29 also lose their connection to the material surrounding them. In a next step, these can be folded over into the area 28 and glued there to the surface of the paper layer 30, as is shown by the arrow 40. This results in a card provided on both sides with film cover layers corresponding to that of FIG. 3, which can finally be removed from the form by destroying the bridge formed by the partial layer 36 of the paper layer 30 along the punched lines 34 and 35 in the area 28.

The embodiment of FIG. 8 has the advantage that the surface of the paper layer 30 is exposed in the area 28 and can be individually labeled or printed on before the card is removed. In the finished card, however, this surface is sealed by the film cover layer 32 originating from the other area 29.

Instead of only one separating layer 33, a multilayered separating layer material of the same function could also be used in the embodiment of FIG. 8. The punching 34 could also be omitted in the region 29, in which case the auxiliary card 39 would then be omitted. In addition, the actual card would have to be removed from the form in the open state and only after it has been removed Fold it up and glue its two parts together.

FIG. 9 shows a form according to FIG. 7 in an embodiment with an integrated vignette, the layer structure from FIG. 9a) being evident. This largely corresponds to that of FIG. 8a), except that instead of only one separating layer 33, two separating layers 41 and 42 are provided on both sides of the pressure-sensitive adhesive layer 31 lying between them. In addition, the form material is provided along the line 37 between the two areas 28 and 29 with a perforation 43 which is punched through all the sub-layers.

The process for creating and removing the vignette is as follows: First, another e.g. Auxiliary card 39 which can be used as a coupon or control card is removed from the area 29 of the form 1, the bridge formed by the partial layer 36 of the paper layer 30 being destroyed along the punched lines 34 and 35 in this area. As a result, the layers 31, 32 and 42 underneath also lose their connection to the material surrounding them in this area and can be folded over into the area 28 in a second step and glued there to the surface of the paper layer 30, as indicated by the arrow 44 is illustrated in Fig. 9b). The resulting structure is shown in Fig. 9c). Proceeding from this structure, a further folding process is required as a third step, in which, however, according to arrow 45 in FIG. 9c) only the two uppermost layers 32 and 42 are folded back from the area 28 back into the area 29. The pressure-sensitive adhesive layer 31 remains on the surface of the paper layer 30 in the area

28 back. The result of the second folding process is shown in FIG. 9d. Taken together, the two folding processes (arrows 44 and 45) lead to a transfer of the pressure-sensitive adhesive layer 31 from the area

29 in area 28. In area 28 the desired vignette is already available and can be destroyed from the form by destroying the bridge formed by partial layer 36 of paper layer 30 along punching lines 34 and 35 in area 28 be detached. Before it is glued behind a pane 47 by means of the pressure-sensitive adhesive layer 31 exposed on its surface according to FIG. 9e), the cover film piece 48 which is still connected to it via the perforation 43 and is previously folded back and forth is separated. A label applied in the area 28 in the original form on the surface of the paper layer 30 can be seen through the pane 47.

In the exemplary embodiments according to FIGS. 8 and 9, the partial layers respectively glued to the back of the paper layer 30 have the same area as the paper layer itself, as a result of which the form as a whole is given a uniform thickness. However, the sub-layers mentioned could be chosen to be smaller in area than the paper layer, if necessary to save material.

The exemplary embodiments explained below with reference to FIGS. 10-16 all relate to forms with cards which comprise a self-adhesive label, as was already the case in the embodiment of FIG. 6. The embodiment of FIG. 10 can then also be derived from that of FIG. 6 by omitting different layers.

In the example of FIG. 10, a release paper with a release layer 52 and a support layer 53 is glued onto the back of a paper layer 50 only by means of a pressure-sensitive adhesive layer 51. The form is stamped from both sides in a congruent manner to the depth of a partial layer 54 in the paper layer 50, as shown in FIGS. 10 a) - c). Fig. 10 d) corresponds to Fig. 10b). 10 e) shows the form with card 55 detached. In FIG. 10 f) it is separated into a simple self-adhesive label 56 and a separating paper part 57.

In Fig. 11 is the example of Fig. 10 for a removal aid 58 for the card 55 on the one hand and a pull-off aid 59 for the Release paper 57 on the other hand added. To illustrate the design and manufacture of these aids, views of the front of the form are shown in FIGS. 11 a) and 11 d), and views of the back of the form are shown in FIGS. 11 c) and 11 f). 11 b) and 11 e) show sectional views CC and DD between the front and rear views, respectively, by means of which the punching depth of the punching lines shown in the top views can be recognized in each case.

Thus, the form of FIG. 11 is punched out from both sides in a congruent manner down to the depth of the sub-layer 54 in the paper layer 50 outside of the aids labeled 58 and 59 according to FIG. 11 a) - c). The same applies to the removal aid 58. In the area of the removal aid 59, on the other hand, the form is not punched from the back. From the front, the form is punched out in this area along section 60 on the edge of the card to the depth of the separating layer 52 and fully punched out along the outer line 61 framing the area of the removal aid 59. As a result of these punchings which are differentiated in terms of their depth, as shown in FIG. 11g), a diecut 62 can first be removed from the area of the removal aid 58, as a result of which a hole is created in the form and a section 63 (FIG. 11a) of the card edge is exposed . By grasping the card 55 at this section 63, it can be easily removed from the form. The extracted card 55 shows Fig. 11 h). The pull-off aid 59 forms a kind of grip tab on the detached card, which is easily grasped and can be used to separate the release paper part 57 from the self-adhesive label 56, as can be seen from FIG. 11 i).

In the embodiment of FIG. 12, the continuous partial layer 64 forming the bridge is a partial layer of the base layer 53 of the release paper 52/53. Otherwise it corresponds to the embodiment of FIG. 10. The example of FIG. 13 combines the concepts of the embodiments of FIGS. 11 and 12, that is to say that here the continuous partial layer 64 forming the bridge is provided in the base layer 53 of the release paper, and additionally a removal aid 58 and a removal aid 59 are provided. In contrast to the example in FIG. 11, however, the form in the area of the removal aid 58 is completely punched out, so that the diecut 62 loses its connection to the material surrounding it during the production of the form and falls out of the form. In the example of FIG. 11, this could of course also be carried out.

The embodiment of FIG. 14 differs from that of FIG. 13 only with regard to the design of the peeling aid 59. In the area of this peeling aid and in terms of area somewhat superior there is locally a separating coating 65 on the back of the form before the application of the pressure-sensitive adhesive layer 51 and the like Release paper 52/53 has been applied. The local release coating 65 is i.a. in Figure 14 c) recognizable. Then, in addition to the punchings from the front, which are carried out according to FIG. 13, a punching is carried out from the back of the form along a line 66 up to the paper layer 50, as can be seen in FIG. 14 e). The punch line 66 runs completely in the area of the card. This punching technique and the separating properties of the local separating coating 65 allow a punch 67 to be removed in the region of the removal aid 59 and thereby an approximately crescent-like grip zone 68 on the back of the card between the card edge and the punch line 66 is exposed, as shown in FIG. 14 g) .

With regard to the removal of the card 55 or the self-adhesive label 56, there are now two possibilities through the grip zone 68: The one shown in FIG. 14 under h) and i) essentially corresponds to that of FIGS. 11-13, ie here the Card 55 completely removed from the form using removal aid 58 in a first step and only then, in a second step, the label 56 is separated from the piece of release paper 57. By pressure from behind on the grip zone 68 mentioned, the self-adhesive label 56 can also be removed from the form separately, ie without the release paper piece 57, the latter remaining in the form. This is shown in Fig. 14 under j). A later additional removal of the release paper piece 57 is of course also still possible.

A separate removal of the self-adhesive label 56, starting from the embodiment of FIG. 13, could also be achieved in that, as shown in FIG. 15 only under a) and b), a T- shows in a corner of the card from the back of the form. shaped die cut 70 in the release paper 52/53 and from the front of the form a short incision 71, which is made at all ends of the layer and is made at the foot of the T, is made. In this embodiment, a pressure with the finger on the card corner provided with the T-shaped incision is sufficient to detach the self-adhesive label separately.

16 shows under a) - c) three variants which would also be applicable in the context of the exemplary embodiments described above:

Under a) it is initially shown that the release paper 52/53 could also protrude somewhat over the surface of the pressure-sensitive adhesive layer 51 on all sides. In this way, a leakage of pressure-sensitive adhesive from the pressure-sensitive adhesive layer 51 beyond the edge of the release paper 52/53 and the risk of a plurality of stacked forms sticking together can be effectively countered. However, only certain types of pressure sensitive adhesives are prone to such a mess.

In Fig. 16 b) the paper layer is laminated over the entire surface with the pressure-sensitive adhesive layer 51 and the release paper 52/53, a possibility which has already been discussed. Although more Coating material is required, there is the advantage of a uniform thickness over the entire form area.

16 c) shows an embodiment in which the die cuts for producing the card 55 are carried out outside the area of the pressure sensitive adhesive 51 and the release paper coating 52/53.

In the examples according to FIG. 17 a) - c), in which, for reasons of a simple illustration, only one paper layer

80 is provided, the double-sided punching 81 on the one hand and 82 on the other hand for the production of the card 83 are not made exactly, but are only essentially congruent, i.e. that they are slightly offset to one side. The punch 81 is executed to a depth T1 and the punch 82 to a depth T2. D is the thickness of the paper layer.

In the example of FIG. 17 a), Tl + T2 <d, so that here, as in the exemplary embodiments described above, an inner partial layer 84 remains imperforate and forms the desired holding bridge.

In the example from FIG. 17 b), Tl + T2 = d, so that the two punchings extend to the same depth of the paper layer 80. A continuous, not punched-through sub-layer is no longer available here. Nevertheless, due to the lateral offset of the two punching lines 81 and 82, there is still a bridge-forming residual thickness holding the card 83 in the form, which, however, is now horizontal in the form instead of vertical or essentially vertical as in the previous examples.

In Fig. 17 c) Tl + T2> d, so that the two punchings

81 and 82 even overlap each other. But here too there is still a residual thickness between the two die cuts. The effective residual thickness naturally also depends on the mutual lateral offset of the two punchings 81 and 82, which, in addition to the punching depths, forms an additional, independent parameter by means of which the residual thickness can be checked and adjusted according to the respective requirements.

18 schematically shows a device with which a coincident or essentially congruent punching for the production of forms of the type according to the invention is possible in one operation. With 90 and 91 two magnetic cylinders are designated, which have ends 92 and 93 of larger diameter running on each other at their ends. 94 and 95 denote thin, metallic stamped sheets which are placed on the surface of the two magnetic cylinders 90 and 91 and adhere magnetically to them. The stamping plates 94 and 95 are provided in a known manner with raised, sharp cutting webs 86 and are at least partially mirror images of these webs. The two punching plates can therefore be positioned on the magnetic cylinders 90 and 91 in such a way that corresponding webs are exactly or at least essentially opposite one another. The diameter of the magnetic cylinders 90, 91, the rollers 92, 92, the thickness of the punching plates 94, 95 and the height of the cutting webs are selected such that they lie directly opposite one another

Interfaces e.g. a residual thickness δ remains approximately in the size of the thickness of a partial layer serving as a bridge.

FIG. 19 shows an embodiment with only one paper layer 100 again. In contrast to the examples described above, the bridge holding the card 101 is formed in an outer partial layer 102 of the paper layer, namely by means of a single punching which is carried out only from one side of the paper layer 103. The punching 103 is also designed such that it is located in the outer partial layer 102 resulting bridge is interrupted in the manner of a perforation, as shown in FIG. 19 b), in which a section EE along the punching line 103 is shown. The area cut by the punch 103 is shown unshaded in FIG. 19 b). Along the punch line 103, fully cut sections 104 alternate with webs 105, which only have the holding function. The height of the webs 105 corresponds precisely to the thickness or residual thickness of the partial layer

102 which e.g. is approximately 50 μ.

Although the fully cut sections 104 and the webs 105 are shown with the same length in FIG. 19 b), they are preferably designed differently, namely the cut sections 104 many times longer than the webs 105. The latter become so short for the respective material selected as possible so that when the card 101 is removed the tear strictly follows the predetermined line and tearing apart from this line is avoided. According to the available experience, webs 105 of approx. 0.1 - .3 mm in length alternating with fully punched sections 104 of approx. 0.5 - 1.0 mm in length are sufficient to hold the card 101 sufficiently firmly in the form 100 ( The card 101 is held sufficiently firmly in the form, for example, if it can be deflected under tension around a deflection roller of 22 mm in diameter without the card 101 being detached). On the detached card 101 such narrow and, due to the only remaining residual strength, even low bridges can hardly be made out optically and tactile and therefore do not have a very disturbing effect, in contrast to the "classic" perforation bridges, the height of which always corresponds to the full material thickness . The great advantage of the embodiment of FIG. 19 is that it only has to be punched from one side in order to be produced.

Removing the card 101 is made even easier by the fact that the form material in the four corner zones 106 is full is punched through, so that the bridge is limited to a part of the straight sections of the card 101. In addition, a removal aid of the type already described could also be provided in the form of a hole adjacent to the card 101, as shown, for example, in FIG. 1.

With regard to processing the forms in printers or the like e.g. predominantly in portrait format, the holding value of the card 101 in the form 100 in the longitudinal and transverse directions can also be set differently by differently selecting the cut-web ratio on the longitudinal and transverse sides of the card 101.

FIG. 20 shows an embodiment corresponding to FIG. 19, only that here the paper layer 110 is also covered with film cover layers 116 and 117 in front and on the back. The corresponding adhesive layers are designated 118 and 119. The sublayer 102 forming the bridge is here formed by the lower film layer 117, the bridge being structured in itself again by a sequence of crosspieces. Despite the rather unfavorable tear properties of plastic films, the card can also be removed from the form cleanly in this embodiment, provided that only sufficiently short webs of the order of 0.1 mm already mentioned are used and the cut-web ratio is about 6: 1 is. The film for the film cover layers 116 and 117 comes e.g. a biaxially stretched

Polyester film of 50 μm thickness in question.

To produce the punchings with differentiated punching depth provided in the embodiment of FIGS. 19 and 20, special punching plates are required. Such a stamped sheet 120 is shown, for example, in FIG. 21 a). 21 a) shows only a part of the punching plate 120 with a short section of a punching web 121. This rises above the remaining level of the punching plate 120, in the area from which it is just about 0.1 mm thick, with an approximately triangular cross-section and is toothed. The height of the web 121 is, for example, 0.44 mm in the area of the teeth 122 and approximately half of it in the area of the interspaces 123, that is to say approximately 0.22 mm.

In the punched sheet of Fig. 21 a), starting from a continuous web 121, the material in the gaps 123 is removed horizontally, which is quite difficult with the mentioned dimensions of the web and the preferred dimensions of the teeth and the gaps mentioned, e.g. is still feasible by milling. However, an actual sharp cutting edge is lost in the gaps. By means of a stamping plate 120 designed in this way, e.g. in the embodiment of Fig. 19, the form material in the area of the webs 105, i.e. where it is not fully cut through by the sharp teeth 122, more squeezed away and / or compressed than cut, which, however, has not proven to be critical.

In the embodiment of FIG. 20, the rather blunt cutting edge in the interstices 123 does not, however, readily allow the film cover layer 117 to be stamped to a certain extent in the area of the webs 105, which would be advantageous if necessary. With a punching plate of the type according to FIG. 21 b), however, this would also be possible in that a cutting edge is also formed in this punching plate 120 ¹ in the spaces 123 ¹ between the teeth 122 ¹ . The stamping plate 120 ¹ from FIG. 21 b) can, however, only be produced with greater effort.

21 c) shows a compromise between the stamped sheets of FIGS. 21 a) and 21 b). In the punched sheet 120 ² shown here, a cutting edge is also present in the spaces 123 ² between the teeth 122 ² , although this also runs transversely with respect to the direction of the punch web 121 ² . Such a cutting edge can, however, be made comparatively easily again with a profile milling cutter, such as, for example schematically shown next to Fig. 21 c) and designated 130.

Fig. 22 shows under a) and b) two sections corresponding to Fig. 19 b), only that here the bridge is again inside a single layer 140 and in this respect e.g. double-sided punching is required for their training. As in the example of FIG. 19 or 20, the bridge is also structured in itself again, namely in FIG. 22 a) in the manner of a saw line and in FIG. 22 b) in the manner of a perforation.

23 shows a section through a form 150 according to the invention with a supporting paper layer 151 and film cover layers 152 and 153 on both sides, which essentially cover only the area of the card 154. The form 150 is now pressed together in the area of the cover layers 152, 153, so that its total thickness in this area is approximately equal to its thickness outside this area. Such training is possible, among other things. because of the advantageous structure of the form according to the invention without the use of a carrier layer which is not part of the finished card. Forms according to FIG. 22 can be stacked better than those with a non-uniform thickness.

The compression of the form in the area of the cover layers can be carried out in a separate operation, but advantageously directly in connection with the punching, as is also the case with the punching plate shown in FIG. 21 a) from crushing and / or compressing the sheet Form material in the area of the punch webs was discussed. In principle, for example, a device according to FIG. 18 would be suitable for a combined punching and compressing. B. on the embodiments according to FIG. 19 or 20, not necessarily both sheets should have punch webs. The bridge could also be realized by completely different means. It would be conceivable, for example, to introduce an adhesive into the die cut during the stamping process, which advantageously has a certain brittleness after curing. In this case, punching could be carried out from just one side. It is also not necessary to punch in the final layer structure. The necessary separating cuts could, for example, be carried out beforehand in individual sub-layers or groups of sub-layers before they are laminated. Finally, the embodiments described above should not be understood as conclusive. In particular, it is possible to use certain features of individual types of embodiment also in other types of embodiment.
