Description

The invention relates to a method for producing a blank of a cover for a book-shaped brochure, which blank is prelaminated with an adhesive film, in particular a prelaminated blank of a cover for an identification, value or security document. The invention also relates to a method for producing a book-shaped brochure, in particular for producing a book-shaped identification, value or security document. The invention further comprises a blank of a cover for a book-shaped brochure and a book-shaped brochure provided with such a cover. The invention also comprises a book-shaped brochure itself, in particular in the form of a book-shaped identification, value or security document.DE 10 2016 218 043 A1 describes a system and method for producing book-shaped identity, value or security documents. These documents consist of an envelope and a passport book block comprising a data card, a plurality of double pages, a front sheet and a counterfeit tape. The data card may contain personal and document specific information and is connected to a flexible tab. The system includes devices for providing and mounting components such as the counterfeit tape and the data card, and for connecting the dual pages and the envelope. An important aspect is the individual sorting and processing of the double pages cut from a sheet of paper. The system enables personalized production of such documents.DE 10 2018 106 126 A1 describes a method for producing a book-shaped identity, value or security document. The document consists of an envelope and a passport book block comprising a data card, a plurality of double pages, a front sheet and a counterfeit tape. The data card may contain personal and document specific information and is connected to a flexible tab. The method includes providing a passbook blank that is milled to a predetermined format in a finishing apparatus. Milling takes place along the free edges of the passbook blank in a plurality of sections, wherein the entry and exit points of the milling tools are selected such that material supernatants are minimized. The system allows for individual manufacture of such documents, wherein the data card may be equipped with a chip that provides secure storage areas for personal data.For the connection of a book block comprising a plurality of pages to a cover, in particular a passport book block, the cover is bonded with its side facing the book block to a front sheet of the book block. Liquid adhesives are typically used here, which frequently represent a water-based suspension. Although these are cost-effective, their use is associated with a prolonged drying time. Within this drying time, the connection between the cover and the book block is to be held together under pressure. In the production of passbooks, in particular identity, value or security documents in book form, reactive adhesives are used, wherein these develop adhesive properties at a first temperature and then completely crosslink only at a second temperature which is greater than the first temperature; consequently cure. Because of the simpler processing, an adhesive film in the form of a film material is used, which is present, for example, in the form of a roll material or also in the form of a sheet. Typically, such adhesive films are applied to the blank of the cover by a transfer foil in the course of a decal process, after which the transfer foil must then be removed in order subsequently to glue the book block, and therefore the front sheet, to the cover.Although the above production of prelaminated blanks of a cover for a book-shaped brochure has proven well in practice, it is the object of the present invention to provide an even simpler method for producing a prelaminated blank and an even simpler method for producing a book-shaped brochure. It is also an object of the invention to provide a blank of a cover, a cover and a book-shaped booklet which can be produced more easily.This object is achieved by a method with the features of claim 1, by a method with the features of claim 8, by a blank with the features of claim 9, by a cover with the features of claim 14 and by a book-shaped brochure with the features of claim 15.The method according to the invention for producing a blank of a cover for a book-shaped brochure that is prelaminated with an adhesive film comprises in particular the following steps:providing the unlaminated blank with predetermined blank dimensions which correspond to the dimensions of a format of the cover plus a trimming allowance surrounded by the final format;applying an uncrosslinked adhesive film to the blank, wherein the dimensions of the adhesive film are at least equal to or greater than the blank dimensions; andintroducing heat into the adhesive film at least in the region of the trim allowance, as a result of which the adhesive film is crosslinked at least in sections with the blank in the region of the trim allowance, and wherein the adhesive film remains uncrosslinked at least in sections in the region of the final format of the cover.In this case, an adhesive film is therefore used which develops adhesive properties (has an adhesive effect) when a predetermined temperature is reached and immediately also cross-links (cures). Thus, there is an adhesive film formed as a simple reacting adhesive. This has the advantage that a simplified adhesive film can be used which is present and adheres only or almost exclusively in the later blank, namely the trim allowance in cross-linked form.It is not necessary to glue the entire surface formed by the trim allowance area. It is sufficient to use narrow adhesive surfaces in the form of lines or even dots. In this context, it is therefore advantageous if the heat input for crosslinking the adhesive film in the region of the trim allowance is linear or punctiform in such a way that at least one crosslinked adhesive line is produced in the region of the trim allowance.Such an adhesive line which is cross-linked can be realized, for example, by using a heating die which has a corresponding contour which is adapted to the adhesive line for cross-linking.Preferably, a plurality of the cross-linked lines of adhesive are present in the region of the cut allowance, which form at least one non-cross-linked passage between an outer edge of the blank and in the region of the final format. As a result of this configuration with uncrosslinked passages, the air still present between the adhesive film and the blank of the cover can thus escape during the folding of the prelaminated blank.Preferably, the cross-linked lines of adhesive or dots are formed very narrow and are at most 3 millimeters (mm), preferably about 1 mm in width. This has the result that no hollow spaces are formed in those regions where the already cross-linked line of adhesive or the adhesive spots are located, since these no longer cross-link additionally during the later connection to the front sheet of the book block. Even elevations between the front sheet and the cover are avoided because no large areas between the front sheet and the cover are present uncrosslinked.In this context, it may also be additionally advantageous if the heat input into the adhesive film is only carried out in sections also in the region of the final format of the cover, in particular in such a way that the uncrosslinked area fraction of the final format remains greater than the crosslinked area fraction of the final format produced by the crosslinking. Due to this area distribution, it is ensured that the larger area proportion can later still be reasonably connected to the front page of the book block and that a non-destructive separation of the cover from the front page also remains impossible; manipulation attempts can thus be avoided.The possibility is created that by the regional cross-linking of the adhesive film in the region of the final format of the cover also security features are realized. In this way, it is advantageous if at least one crosslinked adhesive line and / or at least one crosslinked, in particular punctiform, adhesive spot is produced in the region of the final format of the cover.It is also possible that at least one networked graphical element is generated for generating a security feature in the area of the final format of the cover, in particular in the form of a character or in the form of a letter or in the form of a character string. The graphic elements, the bond lines and the bond spots will later become tactilely detectable when the cover has been bonded to the front sheet of the book block. In the region there, namely, no adhesive bonding is present. The cross-linked graphic elements, cross-linked glue lines and cross-linked glue spots become tactilely or haptically perceptible as embossing.The advantages, advantageous embodiments and effects explained in connection with the method according to the invention for producing the prelaminated blank also apply to the method according to the invention for producing a book-shaped brochure.This method for producing a book-shaped brochure, in particular a book-shaped identification, value or security document, comprises the steps of producing a blank, as has been mentioned above. Furthermore, the steps of applying a front sheet of a book block comprising a plurality of sides to the adhesive film of the prelaminated blank, introducing heat into the adhesive film, so that the adhesive film crosslinks in those regions both with the blank and the front sheet where it is still uncrosslinked beforehand, and cutting the blank bonded to the book block to length to the final format of the cover.The advantages, advantageous embodiments and effects explained in connection with the method according to the invention for producing the book-shaped brochure and with the method according to the invention for producing the prelaminated blank apply in the same way to the blank according to the invention of a cover.This blank according to the invention of a cover for a book-shaped brochure, in particular for a book-shaped identification, value or security document, is prelaminated with an adhesive film. The blank has blank dimensions which correspond to the dimensions of the final format of the cover plus a trim allowance surrounding the final format, wherein the adhesive film is present in cross-linked form at least in sections in the region of the trim allowance and is present in non-cross-linked form at least in sections in the region of the final format of the cover. In this case too, an adhesive film can therefore be used on which a "simple-reacting" adhesive film is based.In order to ensure that the cover is reliably connected to the front sheet of the book block and that these can be separated from one another only with destruction, it is advantageous if an uncrosslinked area fraction in the region of the final format is greater than the crosslinked area fraction in the region of the final format produced by the crosslinking.It has proven advantageous if the adhesive film is present in cross-linked form in the form of an adhesive line or in the form of adhesive spots in the region of the trim allowance. This makes it possible for the adhesive film to be crosslinked point by point or line by line in the region of the trim addition.In order to be able to prevent or expel air inclusions present between the adhesive film and the cover during the folding of the prelaminated blank, it has proven advantageous if a plurality of the cross-linked lines of adhesive are present in the region of the trimming allowance, leaving at least one non-cross-linked passage between an outer edge of the blank and in the region of the final format.In order that the crosslinking in the region of the final format of the cover may remain perceptible as a later security feature or embossing, it has proven advantageous if at least one crosslinked adhesive line and / or at least one crosslinked, in particular punctiform, adhesive spot and / or at least one crosslinked graphic element is present in the region of the final format of the cover, in particular in the form of a character or in the form of a letter or in the form of a character sequence.The advantages, advantageous embodiments and expedient developments and effects explained in connection with the method according to the invention for producing a laminated blank, or with the method according to the invention for producing a book-shaped brochure, and the advantages, advantageous embodiments and advantageous developments and effects explained in connection with the blank according to the invention also apply to the cover according to the invention.This cover of a book-shaped brochure comprises a blank cut or cut to length to the final format of the cover, as explained above.The advantageous embodiments and expedient developments and effects explained in connection with the method according to the invention for producing a laminated blank, or with the method according to the invention for producing a book-shaped booklet, the advantages, advantageous embodiments and advantageous developments and effects explained in connection with the cover also apply to the book-shaped booklet according to the invention, in particular to a book-shaped identification, value or security document provided with an aforementioned cover.It is fundamentally noted that all features disclosed with respect to specific aspects or embodiments of the invention can also be combined technically meaningfully with other aspects or embodiments of the invention. This also applies across different technical items and item categories. In particular, this also applies in part to individual features, as long as it is not explicitly pointed out herein or it is obvious by a technical contradiction that there is an indivisible functional-technical relationship between specific features, which must be retained for carrying out the invention.The invention is explained below with reference to an exemplary embodiment and its diagrammatic illustration. The following are shown here: FIG. 1 is a perspective view of a book-shaped identification, value or security document; FIGS. 2a) to 2f) show method steps for producing the book-shaped identification, value or security document from FIG. 1; FIG. 3 is a top view of a prelaminated blank of a cover which is provided with adhesive sites exclusively in the region of the trim allowance; and FIG. 4 is a top view corresponding to FIG. 3 of a prelaminated blank of a cover which is additionally provided with adhesive sites in the region of the final format of the cover.In Fig. 1, a book-shaped identification, value or security document 100 is shown. The identification, value or security document 100 is, for example, an identification document, in particular a passport or a personal identification card. The identification, value or security document 100 has a cover 102 and a password block 104 held in the cover 102. The passport book block 104 consists of a data card 106, a plurality of passport book pages 108, a header 110 and a counterfeiter tape 112 which are connected to one another by a seam 114.The data card 106 is a plastic or paper-based card on which personal and / or document-specific information is applied. For example, the data map 106 can have a passport image 116 and person-related information 118 of a user. The information 118 is preferably applied to the data card 106 in a machine-readable form. The data card 106 also has a machine readable identification feature that uniquely identifies the data card 106 during the manufacturing process of the identification, value or security document 100. The data card 106 furthermore has a chip in which person- and / or document-specific information can be stored. In particular, the chip has a secured memory area for storing the person- and / or document-specific information. Furthermore, the data card 106 may include visible and / or invisible security features that prevent the data card 106 from being trubated.On the data card 106, a tab 120, in particular a flexible tab, is provided, which is made from an endless belt. The endless belt consists of a fabric which can be coated and / or sheathed with a flexible plastic material. The tab 120 is fastened to the data card 106 in a form-fit and / or firmly bonded manner and thus becomes part of the data card 106. Further security features can be provided on the tab 120.The registration book sides 108 are cut from a sheet of print, preferably a sheet of paper, and are folded along their centerline 122. The passport book pages 108 can be printed, for example with further person- and / or document-specific information, page numbers or other information. In the case of the German passport, these person- and / or document-specific data and information are printed or applied under numerals 11 to 14 on the first passport page or pages 108. The passport book pages 108 can furthermore be prepared for receiving stamps, for example visa stamps. Preferably, the passport book pages 108 also contain security features which prevent the passport book pages 108 from being forged. The security features can be printed, incorporated into the passport book pages 108 or incorporated into the latter, for example. For example, the fit book sides 108 contain a perforation, wherein the perforation through the fit book sides 108 preferably tapers conically.The header 110 forms the outer termination of the passbook block 104. With an outer side 124 of the front page 110, the passport book block 104 is glued to an inner side 126 of the cover 102.The fold tape 112 serves as a reinforcement for the seam area and is glued to the outer side 124 of the front page 110 before sewing the passbook block 104.The production of the identification, value or security document 100 is to be described below with reference to FIGS. 2a to 2f.In a first method step, the data card 106 is provided and the tab 120 is attached to the data card (FIG. 2 a). In this case, the tab 120 is connected to the data card 106 in an overlap region 121 in a form-fit and / or firmly bonded manner and cut to the desired length.The counterfeit tape 112 is then applied to the seam region of the header 110 and the passport book block 104 consisting of the passport book pages 108, the data card 106 and the header 110 is assembled (FIG. 2 b ). The data card 106 is inserted into the passbook block 104 in such a way that the tab 120 is arranged in the seam region.Subsequently, the passport book block 104 is sewn with a seam 114 along the center line 122 of the passport book sides 108 (FIG. 2 c ).After or simultaneously with sewing the passbook block 104, a blank of the cover 102 is provided. The inner side 126 of the blank of the cover 102 is bonded to the outer side 124 of the front sheet 110 and the resulting fit book blank 128 is folded (FIGS. 2 dand 2 e).Subsequently, the free edges of the password blank 128 are processed and thus the password blank 128 is cut to the final format of the identification, value or security document 100 (FIG. 2 f).The present invention is concerned with the provision of the cover 102, in particular with the attachment of an adhesive layer to the cover 102 of the identification, value or security document 100.The present invention is concerned with the application of an adhesive film 130 to a blank of the cover 102, which can then be cut. In this case, the adhesive film 132 has the property that it is present as a readily reacting adhesive film which develops adhesive properties at one and the same temperature and immediately crosslinks.In FIG. 3, the blank of a cover 102 for a book-shaped brochure, in particular for an identity card or security document 100, is shown. In this case, an unlaminated blank having predefined blank dimensions was provided which correspond to the dimensions of a final format 132 of the subsequent cover 102, which is illustrated in dashed lines in FIG. 3, plus a trimming allowance 134 which surrounds the final format 132 and is illustrated here with hatching. Within this trim allowance 136, the adhesive film 130 is only partially crosslinked by the introduction of heat. As a result, the adhesive film 130 adheres there to the blank of the cover 102 in the region of the trim allowance 134. In the region of the final format 132 of the cover 102, however, the adhesive film 130 remains uncrosslinked in sections. The dotted line shows the later folding line for the brochure, and therefore for the later identification, value or security document 100.It can be seen that in the region of the trim allowance 134, the heat input for crosslinking the adhesive film 130 has taken place linearly, so that a plurality of crosslinked adhesive lines 136 have been produced in the region of the trim allowance 134. Furthermore, at least one uncrosslinked passage 138 is present between each two of the adhesive lines 136 between an outer edge of the blank and the region of the final format 132 of the cover 102, so that during the folding along the dotted line, air which is still located between the blank and the adhesive film 130 can escape through these passages 138. The adhesive line 136 in the present case has a width which corresponds to approximately 1 mm, because it is ensured in this way that a sufficient region for the adhesive bonding is present during the later cross-linking to the book block, and therefore to the front sheet 110.FIG. 4 refers to the possibility that even in the area of the final format 132 of the cover 102, a heat input into the adhesive film 103 can take place in sections. In this case, the uncrosslinked area proportion of the final format 132 of the cover 102 is greater than the crosslinked area proportion of the final format 132 produced by the crosslinking. In the present case, in the region of the final format 132 of the cover 102, there is a pair of cross-linked adhesive lines 140 which are arranged symmetrically with respect to the dotted folding line. This arrangement is selected such that the counterfeit tape 112 is marked outwardly on the book cover precisely there in the finished book, wherein the transition from the counterfeit tape 112 to the cover 102 can be optically laminated in this way or else can also be perceived as a precisely defined, visible line. In addition, the optional possibility is shown that at least one cross-linked, in particular punctiform, adhesive spot 142 is produced in the region of the final format 132 of the cover 102, which spot is later perceptible, for example as embossing, in the bonded state.The optional possibility is also shown that at least one networked graphical element 144, for example a logo, is produced in the area of the final format 132 of the cover 102. This graphical element 144 can also be present in the form of a character, in the form of a letter or-as shown merely by way of example in FIG. 4-in the form of a character string.This configuration ensures that only a small portion of the final format 132 is provided with an adhesive film 130 that is already cross-linked before the header 110 is bonded to the blank of the cover 102. Due to the selected surfaces, which will still crosslink with the front sheet 110 later, it is ensured that the largest surface portion of the cover 102 is connected to the front sheet 110 by the adhesive. A non-destructive separation of the cover 102 from the front sheet 110 is therefore no longer possible. After the prelaminated blank of the cover 102 has been adhesively bonded to the book block, in particular to the passbook block 128, the book-shaped brochure thus formed, in particular the book-shaped identification, value or security document 100, is trimmed to its final dimension.As a result, with the solution according to the invention, it is possible to use simpler materials for the adhesive film 130, in particular those which develop and crosslink adhesion properties only in one stage. This reduces the process time for producing book-shaped brochures, in particular book-shaped identification, value or security documents 100. In addition, there is a lower degree of contamination, since no liquid adhesive needs to be used any longer.List of reference characters100 Identification, value or security document 102 cover 104 password block 106 data card 108 password pages 110 header 112 counterfeit tape 114 seam 116 password 118 data or information 120 tab 121 overlap region 122 center line 124 outer side of the header 126 inner side of the cover 128 password blank 130 adhesive film / adhesive layer 132 final format (cover) 134 trim allowance 136 adhesive line (trim allowance) 138 passage (trim allowance) 140 adhesive line (final format) 142 adhesive spot (final format) 144 graphic element (final format)
