Abstract

The card (3) is a punched formation held by the support layer (21) in the form and produced from the front side to the support layer. The support material in the punching direction in front of the peeling glue (22) and support layers (21) additionally has a first permanent adhesive layer (24) together with a first cover layer (23). The support material viewed in the punching direction has a first dividing layer (25) as last outermost layer. The peeling glue layer (22) when viewed in the punching direction comprises a first part layer with a non-permanent adhesive or a peeling glue and a second part layer with a permanent adhesive.

Description

TECHNICAL AREA

The present invention relates to a form with removable Card, being on the back of the form, the area a base material at least partially covering the card is glued on, which in addition to a backing layer Includes peeling layer with respect to the card and being the card is a die cut created by a die cut in the form.

Under the "layer of peel with respect to the map" there should be one Glue layer to be understood, which on the one hand to the carrier layer permanent adhesive effect on the card side however no permanent adhesive effect developed and by which the card therefore without glue residue on you remain, let it detach. An adhesive effect becomes permanent then viewed when the layers glued together not easily separated from one another without destruction can be.

The invention further relates to a manufacturing method for a Form of the aforementioned type.

Forms with a removable card are increasingly used by Organizations used to collect contributions at the same time a membership or ID card to the addressee to transfer.  

STATE OF THE ART

A known form with a removable card are Cover layers glued on both sides on a form sheet and the card is punched through all layers in the Form sheet generated. Die bars are left with it the card does not fall out of the form. For the top layers is a transparent film material used by which determines the appearance of the map Imprint on the form visible in the area of the map is. The cover layers serve to protect this print, for Achieving a smooth, water-repellent surface as well as Reinforcement of the card.

The punch webs have been disadvantageous in the known form proven. On the one hand, they act on the detached Map both visually and tactically disruptive and on the other hand form Problem areas where the risk of tearing the card exists when you remove it. After removing the The card always leaves a hole in the form.

From the older but later published EP-A1-0613792 a form of the type mentioned is known, in which one is manufactured in a separate operation Card after punching out a sufficiently large hole in the form and sticking the back with a peel glue provided carrier material is inserted into the hole. Because of The manufacturing and positioning tolerances must be certain Distance between the outer circumference of the card and the inner one Edges of the punched hole are observed. The production the card in separate operations and their positioning in the punch hole of the form sheet is relatively complex.

From FR-A-2691675 is known a form of the type mentioned, wherein a transparent film is used as the carrier material. Between the form material and the carrier material is one second film inserted with a permanent pressure sensitive adhesive is glued to the back of the form. By all Through layers, following the edge of the second film is one   all-round perforation with punched ridges. Through the Perforation and the properties of the peel layer can be in in a first step a card plasticized on one side the form, which are extracted from the form material and the glued-on second film. When detaching the second film separates from the peel layer. Around It is planned to obtain a plasticized film on both sides, the card plasticized on one side is turned into the card Pull out the resulting hole and onto the exposed one To stick peeling glue layer. Here the Schälim should be with enter into a permanent connection with the form material. Finally, the carrier layer can also be in the film perforation applied now plasticized on both sides Card can be removed from the form.

From the partially older, but later published EP-A1-0 658 423 is a form with a removable card known, being on the back of the form, the area of the card at least partially covering, a carrier material glued on is which, in addition to a carrier layer, a glue layer includes and where the card one by punching in the form is produced. The layer of glue has the property that it tears when you remove the card, with a Some of the glue remains on the carrier layer, another However, part goes with the card.  

PRESENTATION OF THE INVENTION

The object of the invention is to create a form with removable card that avoids the aforementioned disadvantages, where the card can be removed at least as easily leaves and until then at least as safe on the form level is held. The invention is also intended a specify a suitable manufacturing process.

This task is solved with a form at the beginning mentioned type according to claim 1 in that the Punching from the front of the form to the base layer out as well as all the way around without leaving the punch webs is that the card is through the shell glue alone is kept in the form and that the Schälim the peeling layer is set so that after the peeling from the card is practically no longer sticky.

Claim 18 relates to a manufacturing method according to the invention.

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

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. With 2 is a preferably rectangular piece of a carrier material designated, which a carrier layer 21 and a Peel layer 22 includes. The carrier layer 21 is mediated the Schälimschicht 22 glued to the back of the form.

From the front of the form sheet 1 is as through the Arrows in Fig. 1a) clarify within the surface of the carrier material 2 a preferably fully rotating, i.e. bridge-free Punching carried out, which the form sheet 1 and the Peel layer 22 passes through and up to the carrier layer 21 reaches down. It is harmless if the carrier layer 21 something is stamped with it, as long as it thereby supports it Properties not losing.

Due to the preferably all-round punching a die cut or card 3 is cut out of the form sheet 1, that with the surrounding material of the form sheet 1 no longer has a connection and only through the carrier layer 21 not punched through in the form sheet 1 is held.

The sound in the layer 22 is adjusted in a known manner that the card 3 on the one hand is sufficiently firm and secure Form sheet 1 is held, i.e. yourself as intended Fiddling with form sheet 1 or even its automatic Processing does not replace prematurely, on the other hand but can be easily removed from the sheet 1. When detaching of the card, the shell in 22 must be completely on the support layer   21 remain. So he shouldn't like this at Self-adhesive labels just the other way around, together replace with card 3. In this respect, the peeling layer 22 has to the carrier layer 21 a permanent one and to the form sheet 1 towards a non-permanent adhesive effect.

Fig. 1b) shows the form with the detached card 3. Recognizable is the peel layer 22 on the carrier layer 21 remained and did not "go with card 3". The card 3 is therefore not self-adhesive.

Preferably, the peeling layer 22 is also set so that that they are practical after detaching from card 3 is no longer sticky.

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

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

In the example of FIG. 2, the backing material 2 comprises in addition to a carrier layer 21 and a peel layer 22 a cover layer 23 and a permanent pressure-sensitive adhesive layer 24. On the front of the form there is preferably a like the carrier material 2 rectangular piece of a covering material 4th provided, which also has a cover layer 41 and a Permanent PSA layer 42 comprises. The two top layers 23 and 41 are preferably transparent plastic films, through which a possible imprint on the form sheet 1 can be seen in the area of the card 3. The top layers serve to stiffen the card 3 and can   you also have a water-repellent and abrasion-resistant surface borrow.

Instead of a plastic film, the cover layers 23 and 41 also from a paper material with preferably similar ones Properties such as Parchment paper. The usage a paper material for at least one of the two cover layers 23 or 41 would have the advantage that this top layer would be writable. On the other hand, methods are also known (e.g. by applying a matting) with which smooth Foil surfaces can be made inscribable.

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

The carrier material 2 is preferably complete as such prefabricated and then as a whole on the back of the form upset. This is much more economical than the application of the individual layers one after the other. The carrier material can in particular as continuous material in roll form to the form manufacturer from a specialized film manufacturer or film refiners can be delivered. Because the top layer 24 is a permanent layer of pressure sensitive adhesive, special measures must be taken be taken so that the carrier material 2 on itself itself can be rolled up. Such a measure is a back one Release coating of the carrier layer e.g. by means of a silicone application. Such is designated by 25 in FIG. 2. Alternatively could the carrier material 2 initially with a additional release paper layer provided at the Form production would then be waste.

In Fig. 3, the sound glue layer 22 in the carrier material 2 is through an essentially identical double layer a first sub-layer 221 and a second sub-layer 222 formed. For the first sub-layer 221 again a peel with respect to the top layer 23 (A peel glue is a special non-permanent one   Pressure sensitive adhesive) and a permanent one for the second sub-layer 222 Pressure sensitive adhesive (with respect to the carrier layer 21) is used.

Such a double layer is also in the example of FIG. 4 221/222 used. In addition, here is still between the second, permanent pressure-sensitive adhesive layer 222 and the carrier layer 21 a separating layer 26, e.g. a 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 less than the adhesive value layer 221 to cover layer 23. When removing the card 3 therefore goes with the double layer with this, as shown in FIG. 4b) shows. Together with the double layer, the Card 3 a self-adhesive label 3 ', which in another place, e.g. on another Paper substrate 11, can be glued again, as shown in Fig. 4c) shows.

Because of the explained properties of the double layer 221/222 it is then still possible to use card 3 also detach from their new carrier 11, like this shows Fig.4d). Because of the on the new carrier 11 in the The pressure-sensitive adhesive develops normally no existing release coating of the sublayer 222 to its surface is permanent Adhesive effect which is greater than the non-permanent adhesive effect between the first sub-layer 221 and the cover layer 23. The separation now takes place when card 3 is removed between the latter two layers. The double layer 221/222 remains on the new carrier 11 like this Fig. 4d) shows.

5 corresponds functionally to that of Fig. 4, only that additionally between the two sub-layers 221/222 a subcarrier layer 223 is inserted. This goes when the card 3 is removed from the form sheet 1 initially also with (Fig.5b)), but remains after re-gluing on a new support 11 (Fig.5c)) and the subsequent detachment from this back on the new carrier (Fig.5d)). The solution with the subcarrier layer 223 instead of only of the two non-self-supporting layers 221 and 222   be advantageous in terms of manufacturing technology. For the subcarrier layer 223 comes optionally, as for the other load-bearing ones Layers, a paper or foil material in question.

In FIG. 6 the layer structure of FIG. 2 is in the carrier material 2 around a self-supporting layer 28 and a permanent pressure-sensitive adhesive layer 27 and in the covering material 4 around a self-supporting Layer 43 and a permanent pressure-sensitive adhesive layer 44 expanded. The additional layers 28 and 43 serve for further Stiffen the card 3 and consist advantageously of the same material as form sheet 1 itself. You can then in the same process as the form sheet a secondary web are printed, as shown in FIG. 7.

Fig. 7 shows an endless web 12 of already printed form sheets 1, which are connected via perforation lines 13. Laterally connected to the web 12 from the form sheets 1 and a secondary web 14 is printed with these at the point indicated by the arrow P from the main track 12 separated and wound on a roll 15. The Main web 12 is wound on another roll 16. Per Form sheet 1 in the main line 12 can be on the secondary line 14 usually two print jobs with the one for the substrate 2 and the cover material required size attached will. One of these is designated 18. A print job appropriate size on the form sheets 1 in the area the later card is designated 19.

In FIG. 8, the carrier material 2 is the same as in FIG. 2 used, but that of Fig. 1, 3 or 6 the same would be applicable. In cover material 4 on the front of the form is here between a cover layer 41 and one Permanent pressure-sensitive adhesive layer 42 an additional release layer 45 intended. After removing the card 3 can therefore how 8c) shows the cover layer 41 together with (its) Release coating 45 detached and the pressure-sensitive adhesive layer 42 be exposed. The card 3 'is then on its front self-adhesive and can, as shown in Fig.8d), like a Vignette e.g. be glued to a glass pane 17.  

Also in the exemplary embodiment in FIG. 9, the carrier material is 2 that of Fig. 2 used, that of Fig. 1, 3 or 6 again would be equally applicable. 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 a cover layer 41 and a permanent pressure-sensitive adhesive layer 42, another Material 5 with a load-bearing layer 51 (paper or film) and a release coating 52 toward the pressure sensitive adhesive layer 42 inserted, which is simply referred to below as release paper becomes. The covering material 4 projects beyond the release paper 5 on both sides, whereby in the two emerging edge zones 46 and 47 permanent adhesion of the covering material 4 to the front of the form comes about. Merely from acting Reasons is the thickness of the pressure sensitive adhesive layer 42 in the above Border zones exaggerated. In reality it should be even and the cover material 4 to the release paper 5 adjust. This occurs at the usual layer thicknesses only a negligible gradation.

The punching to produce the card 3 is now carried out that a punching line 31 comes to lie in the edge zone 46 and the other 32 passes through the release paper 5. The two too remaining punching lines 33 and 34 are selected so that they are in the Cover area of the covering material 4 with the release paper lie. Fig. 9c) shows a kind of top view schematically relative arrangement of the individual layers or materials to each other as well as the location of the punching lines mentioned fixed card 3. In FIG. 9, the material pieces 2, 4 and 5 shown different sizes for illustration purposes. 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 the same size and smaller be chosen as the covering material.

After the card 3 has been removed in the example of FIG. 9, 9d), because of the release paper 5, the cover material 4 of the Surface of the layer originating from form sheet 1 by bending on one side be lifted off. It only sticks to the edge zone 48   firmly. Due to its preferably large enough the selected inherent stiffness releases the release paper 5, as can also be seen in FIG. 9d), in the bending zone 49 a piece far from the covering material 4, can therefore easily be grasped there and, as shown in Fig. 9e), are removed. Below can the covering material 4 permanently on the surface mentioned be glued. The corresponding structure is shown in Fig. 9f, the thickening of the PSA layer is not actually present but on The selected representation is based, as already explained.

The embodiment of Fig. 9 makes sense especially if the Cover layer 41 of the covering material 4 is transparent. In the Map of Fig. 9 can then advantageously on said surface e.g. individual labeling can be carried out by hand, which after removing the release paper 5 and the permanent Glue the covering material 4 through the transparent cover layer 41 recognizable through, but sealed by and is made inaccessible. It could also be a passport photo of a Glued person between said surface and the covering material 4 will.

Although the die-cut to produce the card according to the present Invention preferably all the way round, i.e. without leaving can be performed by punching bars in the embodiment of Fig. 9 e.g. to those designated 35 and 36 in Fig. 9c) Places such bars are left at certain points, to prevent the cover material 4 from moving prematurely lifts off the map surface and may cause problems in form processing, especially in laser printers arise.

The example of FIG. 10 corresponds functionally to that of FIG. 9, only that here is a piece of release paper 5 between the form Back and the substrate 2 is inserted. The resulting Map 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 within the card area,   i.e. an additional one within the punching lines 31 and 32 Die cut 6 (window or strip) and the Punch was subsequently removed. The back of the card 3 is therefore exposed in the window area and can be used e.g. be printed.

In the example in FIG. 12 there is a corresponding punch 6 performed. Since here, however, the layer structure of the Fig. 2 corresponds to the surface by punching 6 of the cover layer 23, which is preferably a film is. To ensure that the back of the card can be labeled or printed on in form sheet 1, this can be done in Window area be provided with a matting 7.

13 shows a semi-circular top view Punch 8, the chord through the punch line 31 is formed and which is as deep as the other die cuts 32 - 34 is executed. The resulting, regarding its layer structure is in agreement with card 3 Diecut 81 is removed from the form sheet 1, causing a practical removal aid for card 3 results.

With regard to the carrier material 2 and FIG. 2, it has already been stated that this is preferred in an endless form by one on top of it specialized manufacturer completely prefabricated and from the form manufacturer just cut to size and on the form sheets 1, preferably again in an endless process becomes. Of course, this also applies to the others Variants of carrier materials as well as for the covering materials 4th
