Description

DESCRIPTION

TITLE

Form with detachable card as well as carrier, masking material and manufacturing process therefor

TECHNICAL AREA

The present invention relates to a form with a removable card, a backing material being glued to the back of the form, at least partially covering the area of the card, which, in addition to a backing layer, comprises a peel layer with respect to the card. The "peeling glue layer with respect to the card" is to be understood here as a glue layer which, on the one hand, develops a permanent adhesive effect towards the backing layer, on the other hand, however, no permanent adhesive effect towards the card and from which the card therefore develops without any glue residues on it remain, can be replaced. An adhesive effect is considered permanent if the layers bonded to one another can no longer be separated from one another easily without destruction.

The invention further relates to a carrier material and a covering material for a form of the aforementioned type and a manufacturing process therefor.

Forms with a removable card are increasingly used by organizations today to collect contributions and at the same time to transmit a membership or ID card to the addressee.

STATE OF THE ART

In a known form with a removable card cover layers are glued on both sides of a form sheet and the card is created by punching through all layers in the form sheet. Punch bars are left so that the card does not fall out of the form. A transparent film material is used for the cover layers, through which a print on the form determining the appearance of the card is visible in the area of the card. The cover layers serve to protect this print, to achieve a smooth, water-repellent surface and to reinforce the card.

The punch webs have proven to be disadvantageous in the known form. On the one hand, they have a visual and tactile disruptive effect on the removed card and, on the other hand, form problem areas where there is a risk of the card tearing when it is removed. After removing the card, there is always a hole left in the form.

From EP-AI-0613792 a form of the type mentioned is known, in which a card produced in a separate operation is punched into the hole after punching out a sufficiently large hole in the form and gluing the backing of the carrier material provided with a sound. Because of the manufacturing and positioning tolerances, a certain distance between the outer circumference of the card and the inner edges of the punched hole must be maintained. The production of the card in separate work steps and its positioning in the punched hole of the form sheet is relatively complex.

PRESENTATION OF THE INVENTION

The object of the invention is to create a form with a removable card, which avoids the aforementioned disadvantages, but in which the card can be removed at least as easily and is kept at least as securely in the form plane until then. The invention is also intended to provide suitable carrier and cover materials and to specify a suitable production process.

The solution to this problem in the case of a form of the type mentioned at the outset according to claim 1 is that the card is a die-cut which is held in the form by the carrier layer and is produced by a die-cut made from the front of the form to the carrier layer.

Backing materials are characterized in claim 19, covering materials in claim 20. Claim 21 relates to a manufacturing method according to the invention.

Advantageous refinements and developments of the subject matter of the invention are each characterized in the dependent claims.

Exemplary embodiments of the invention are described below with reference to the accompanying drawings.

WAY OF CARRYING OUT THE INVENTION

In Fig. 1, 1 denotes a form sheet. This consists e.g. made of paper, on which any information, a pattern or the like can be printed on one or both sides. 2 denotes a preferably rectangular piece of a carrier material, which comprises a carrier layer 21 and a peel layer 22. The carrier layer 21 is glued to the back of the form by means of the peel layer 22.

From the front of the form sheet 1, as illustrated by the arrows in FIG. 1 a), a preferably all-round, i.e. web-free punching, which passes through the form sheet 1 and the peel layer 22 and extends down to the carrier layer 21. It is harmless if the carrier layer 21 is stamped with something, as long as it does not lose its load-bearing properties as a result.

Due to the preferably completely running punching, a diecut or a card 3 is cut out of the form sheet 1, which has no connection with the surrounding material of the form sheet 1 and only through the carrier layer not punched through 21 is held in the form sheet 1.

The peel in the layer 22 is set in a known manner in such a way that the card 3 is held sufficiently firmly and securely in the form sheet 1 on the one hand, that is, it does not prematurely handle the form sheet 1 as intended or its automatic processing detaches, but on the other hand is easily removable from the sheet 1. When the card is removed, the shell 22 must be completely on the carrier layer 21 remain. So he shouldn't like this at

Self-adhesive labels just the other way round, peel off together with card 3. The peeling layer 21 thus has a permanent adhesive effect on the carrier material 21 and a non-permanent adhesive effect on the form sheet 1.

1b) shows the form with the card 3 detached. As can be seen, the peeling layer 22 has remained on the carrier layer 21 and has not "walked" with the card 3. The card 3 is therefore not self-adhesive.

Preferably, the peeling layer 22 is also adjusted so that it is practically no longer sticky after the card 3 has been removed.

A paper or film material can be used for the carrier layer 21. Like the form, this can carry a print job. It can be transparent or opaque. In the latter case, a print job would initially be hidden on the card-side surface of the carrier layer 22 and on the back of the card and would only become visible when the card 3 was removed.

All of the exemplary embodiments described below are based on the above basic structure, the repeated explanation of which is therefore also omitted in each case.

In the example of FIG. 2, the backing carrier material 2 comprises, in addition to a carrier layer 21 and a peeling layer 22, a cover layer 23 and a permanent pressure-sensitive adhesive layer 24. On the front of the form, a piece of covering material 4, which is preferably rectangular, is provided , which also comprises a cover layer 41 and a permanent pressure-sensitive adhesive layer 42. The two cover layers 23 and 41 are preferably transparent plastic films, through which a possible print on the form sheet 1 in the area of the card 3 can be seen. The cover layers further serve to stiffen the card 3 and can also give it a water-repellent and abrasion-resistant surface.

Instead of a plastic film, the cover layers 23 and 41 could also be made of a paper material with preferably similar properties, e.g. Parchment paper. The use of a paper material for at least one of the two cover layers 2 or 4 would have the advantage that this cover layer would then be inscribable. On the other hand, methods are also known (e.g. by applying a matting) with which smooth film surfaces can be made inscribable.

It goes without saying that, depending on the application, only one of the two cover layers 23, 41 can also be provided, for which purpose the cover layer 23 is appropriate, since this part of the carrier material 2 and the carrier layer 21 are required anyway.

The carrier material 2 is preferably completely prefabricated as such and then applied as a whole to the back of the form. This is much more economical than applying the individual layers one after the other. The carrier material can be supplied to the form manufacturer in particular as a continuous material in roll form by a film manufacturer or film refiner specialized for this purpose. Since the top layer 24 is a permanent pressure-sensitive adhesive layer, special measures must be taken so that the carrier material 2 can be rolled up on itself. Such a measure is a back-side release coating of the carrier layer e.g. by means of a silicone order. Such is designated by 25 in FIG. 2. Alternatively, the carrier material 2 could initially also be provided with an additional release paper layer, which would then be generated as waste during the production of the form.

In FIG. 3, the peel glue layer 22 in the carrier material 2 is formed by an essentially identical double layer consisting of a first partial layer 221 and a second partial layer 222. For the first sub-layer 221, a non-permanent pressure sensitive adhesive (with respect to the cover layer 23) or again a peel glue (a peel glue is a special, non-permanent ter pressure-sensitive adhesive) and a permanent pressure-sensitive adhesive (with respect to the carrier layer 21) is used for the second sub-layer 222.

Such a double layer 221/222 is also used in the example of FIG. 4. In addition, there is a separating layer 26 between the second, permanent pressure-sensitive adhesive layer 222 and the carrier layer 21, e.g. siliconization of the carrier layer 21 is provided. The two adhesive layers 221 and 222 are further adjusted so that the adhesive value of the layer 222 to the separating layer 26 is lower than the adhesive value of the layer 221 to the cover layer 23. When the card 3 is removed, the double layer therefore goes along with it, as shown in FIG. 4b) shows. The card 3 is then, like a self-adhesive label, self-adhesive and can be placed at another location, e.g. on another paper substrate 11, as shown in FIG. 4c).

Because of the explained properties of the double layer 221/222, however, it is then still possible to detach the card 3 as card 3 'from its new carrier 11, as shown in FIG. 4d). Because the release coating is generally not present on the new carrier 11, the pressure-sensitive adhesive of the partial layer 222 develops a permanent adhesive effect on its surface, which is greater than the non-permanent adhesive effect between the first partial layer 221 and the cover layer 23. The separation Therefore, when the card 3 ¹ is detached, it now takes place between the latter two layers. The double layer 221/222 remains on the new carrier 11, as shown in FIG. 4d).

5 corresponds functionally to that of FIG. 4, except that an auxiliary carrier layer 223 is additionally inserted between the two sub-layers 221/222. When the card 3 is removed from the form sheet 1, this initially goes with (FIG. 5b)), but remains on the new carrier 11 (FIG. 5c)) after being stuck on again and the subsequent detachment from the latter new carrier back (Fig.5d)). The solution with the auxiliary carrier layer 223 instead of only the two non-self-supporting layers 221 and 222 can be advantageous in terms of manufacturing technology. For the auxiliary carrier layer 223, as with the other supporting layers, a paper or film material can be used.

In FIG. 6, the layer structure of FIG. 2 is expanded in the carrier material 2 by a self-supporting layer 27 and a permanent pressure-sensitive adhesive layer 28 and in the cover material 4 by a self-supporting layer 43 and a permanent pressure-sensitive adhesive layer 44. The additional layers 27 and 43 serve to further stiffen the card 3 and advantageously consist of the same material as the form sheet 1 itself. They can then be printed on a secondary web in the same operation as the form sheet, as shown in FIG. 7 shows.

FIG. 7 shows an endless web 12 of already printed form sheets 1 which are connected via perforation lines 13. A side web 14 is laterally connected to the web 12 from the form sheets 1 and printed together with them. This is separated from the main web 12 at the point indicated by the arrow 17 and wound up on a roll 15. The main web 12 is wound on another roll 16. For each form sheet 1 in the main web 12, two print jobs with the size 1 required for the carrier material 2 and the covering material can generally be applied to the secondary web 14. One of these is designated 18. A print job of corresponding size on the form sheets 1 in the area of the later card is designated by 19.

In FIG. 8, the same material as in FIG. 2 is used as the carrier material 2, although that of FIGS. 1, 3 or 6 would also be applicable. In the covering material 4 on the front of the form, a separating layer 45 is additionally provided here between a cover layer 41 and a permanent pressure-sensitive adhesive layer 42. After the card 3 has been removed, the cover layer 41 together with (its) release coating 45 can therefore be removed and the pressure-sensitive adhesive layer 42 exposed, as shown in FIG. 8c). The card 3 'is then self-adhesive on its front side and, as shown in FIG. 8d), can be glued in the manner of a vignette, for example to a glass pane 17. Also in the exemplary embodiment in FIG. 9, that of FIG. 2 is used as the carrier material 2, the one in FIG. 1, 3 or 6 again being applicable in the same way. The modification is also on the front of the form. There is under the cover material 4, which corresponds to that of FIGS. 2-5 and includes a cover layer 41 and a permanent pressure-sensitive adhesive layer 42, a further material 5 with a load-bearing layer 51 (paper or film) and a release coating 52 towards the pressure-sensitive adhesive layer 42 inserted, which is hereinafter simply referred to as release paper. The cover material 4 projects beyond the release paper 5 on both sides, as a result of which the cover material 4 is permanently bonded to the front of the form in the two resulting edge zones 46 and 47. The thickness of the pressure-sensitive adhesive layer 42 in the edge zones mentioned is exaggerated only for illustrative reasons. In reality, it should be uniform and the covering material 2 should adapt to the backing paper 5. With the usual layer thicknesses, there is only a negligible gradation.

The punching for producing the card 3 is now carried out in such a way that one punching line 31 comes to lie in the edge zone 46 and the other 32 passes through the release paper 5. The two remaining punching lines 33 and 34 are also selected such that they lie in the area of overlap of the covering material 4 with the release paper. FIG. 9c) shows in a type of top view schematically the relative arrangement of the individual layers or materials to one another and the position of the card 3 defined by the punching lines mentioned. In FIG. 9, the pieces of material 2, 4 and 5 are of different sizes for reasons of illustration shown. In the direction of the punch lines 31 and 32, however, they could all have the same extent. The carrier material 2 in the direction of the punching lines 33 and 34 could also be selected to be the same size and smaller than the cover material.

After the card 3 has been removed in the example of FIG. 9, as shown in FIG. 9d), the covering material 4 can be lifted off the card surface due to the release paper 5 by bending it on one side. It only sticks to the edge zone 48 this tight. Due to its inherently stiffness, which is preferably chosen to be sufficiently large, the separating paper 5, as can also be seen in FIG. 9d), dissolves a little in the bending zone 49 from the covering material 4, can therefore be easily grasped there and, as shown in FIG. 9e) , be removed. Subsequently, the covering material 4 can be permanently adhered to the entire surface of the card. The corresponding structure is shown in FIG. 9f, the thickening of the pressure-sensitive adhesive layer that can be seen in the edge zone 48 not actually being present but based on the selected representation, as already explained.

The embodiment of FIG. 9 makes sense above all if the cover layer 41 of the cover material 4 is transparent. In the case of the map of FIG. 9, e.g. an individual inscription can be made by hand, which can be recognized through the transparent cover layer 41 after the release paper 5 has been removed and the cover material 4 has been permanently adhered, but is sealed and made inaccessible by this. A passport photo of a person could also be glued between the card surface and cover material 4.

Although the punching for generating the card according to the present invention is preferably all-round, i.e. 9 without the use of punch webs, in the embodiment of FIG. At the points designated 35 and 36 in FIG. 9c), such webs are left at certain points in order to prevent the covering material 4 from lifting off prematurely from the card surface and thereby possibly problems in form processing, in particular in laser printing - core arise.

The example of FIG. 10 corresponds functionally to that of FIG. 9, except that here a piece of release paper 5 is inserted between the back of the card and the carrier material 2. The resulting card 3 is clearly a mirror image of that of FIG. 9.

FIG. 11 shows an embodiment according to FIG. 1, in which, however, in the backing material 2 inside the card holder Reichs, ie an additional punch 6 (window or strip) was made within the punching lines 31 and 32 and the punched item was subsequently removed. The back of card 3 is therefore exposed in the window area and can, for example, be printed with advantage.

In the example of FIG. 12, a corresponding punching 6 is made. Since here, however, the layer structure otherwise corresponds to that of FIG. 2, the punched-out 6 exposes the surface of the cover layer 23, which is preferably a film. In order to ensure that the back of the card in form sheet 1 can also be inscribed or printed on, this can be provided with a matting 7 in the window area.

13 finally shows a top view of a semicircular punching 8, the chord of which is formed by the punching line 32 and which is of the same depth as the other punchings 32-34. The resulting die cut 81, which corresponds to the card 3 in terms of its layer structure, is removed from the form sheet 1, which results in a practical removal aid for the card 3.

With regard to the carrier material 2 and FIG. 2, it has already been stated that this is preferably prefabricated completely in a continuous form by a manufacturer specialized in it and only cut to length by the form manufacturer and onto the form sheets 1, preferably again in an endless process, is donated. Of course, this also applies to the other variants of carrier materials and to the covering materials 4.
