Description

[0001] The invention relates to a method for producing a cover blank for a book-shaped brochure, in particular a cover blank for an identification, valuables, or security document, pre-laminated with an adhesive film. The invention also relates to a method for producing a book-shaped brochure, in particular for producing a book-shaped identification, valuables, or security document. Furthermore, the invention comprises a cover blank for a book-shaped brochure and a book-shaped brochure provided with such a cover. Furthermore, the invention comprises a book-shaped brochure itself, in particular in the form of a book-shaped identification, valuables, or security document.

[0002] To join a book block comprising several pages to a cover, particularly a passport book block, the cover is glued to a front page of the book block with the side facing the book block. Typically, liquid adhesives are used, which are often a water-based suspension. Although these are inexpensive, their use is associated with an extended drying time. During this drying time, the bond between the cover and the book block must be held together under pressure. In the production of passport books, particularly identity, valuables, or security documents in book form, reactive adhesives are used. These develop adhesive properties at a first temperature and only then fully crosslink, i.e. harden, at a second temperature that is higher than the first temperature.Due to its ease of processing, an adhesive film in the form of a foil material is used, which is available, for example, in roll form or in sheet form. Typically, such adhesive films are applied to the cover blank using a transfer film as part of a decal process. The transfer film must then be removed before the book block, and thus the endpaper, can be bonded to the cover.

[0003] Although the above production of pre-laminated blanks for a cover for a book-shaped brochure has proven successful in practice, the object of the present invention is to provide an even simpler method for producing a pre-laminated blank and an even simpler method for producing a book-shaped brochure. Furthermore, the object of the invention is to provide a cover blank, a cover, and a book-shaped brochure that can be produced more easily.

[0004] This object is achieved by a method having the features of claim 1, by a method having the features of claim 8, by a blank having the features of claim 9, by a cover having the features of claim 14 and by a book-shaped brochure having the features of claim 15. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims.

[0005] The method according to the invention for producing a blank cover for a book-shaped brochure pre-laminated with an adhesive film comprises in particular the following steps: Providing the unlaminated blank with predetermined blank dimensions that correspond to the dimensions of a cover format plus a trim allowance surrounding the final format; applying an uncrosslinked adhesive film to the blank, wherein the dimensions of the adhesive film at least correspond to or are greater than the blank dimensions; and introducing heat into the adhesive film at least in the region of the trim allowance, whereby the adhesive film crosslinks with the blank at least in sections 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.

[0006] This involves using an adhesive film that develops adhesive properties (appears to be sticky) when a specified temperature is reached and immediately crosslinks (cures). This results in an adhesive film that is formed as a single-reacting adhesive. This has the advantage that a simplified adhesive film can be used that is crosslinked and adheres only or almost exclusively in the subsequent cut, namely the trimming area.

[0007] It is not necessary to bond the entire surface formed by the trim allowance. Instead, it is sufficient to use narrow bonding surfaces in the form of lines or even points. In this context, it is therefore advantageous if the heat input for crosslinking the adhesive film in the trim allowance area is linear or point-like, so that at least one crosslinked adhesive line is created in the trim allowance area.

[0008] Such a cross-linked adhesive line can be realized, for example, by using a heating stamp that has a corresponding contour that is adapted to the adhesive line for cross-linking.

[0009] Preferably, a majority of the cross-linked adhesive lines are located in the trim allowance area, forming at least one uncross-linked opening between an outer edge of the blank and in the final format area. This design with uncross-linked openings allows any remaining air between the adhesive film and the cover blank to escape during folding of the pre-laminated blank.

[0010] Preferably, the cross-linked adhesive lines or dots are formed very narrowly, measuring no more than 3 millimeters (mm), preferably approximately 1 mm in width. This ensures that no voids are created in the areas where the already cross-linked adhesive line or dots are located, as these will no longer be further cross-linked during subsequent bonding to the endpaper of the book block. Bumps between the endpaper and the cover are also avoided because there are no large areas between the endpaper and the cover that are uncross-linked.

[0011] In this context, it can also be advantageous if the heat is applied to the adhesive film only in sections, including the final format of the cover, particularly in such a way that the uncrosslinked surface portion of the final format remains larger than the crosslinked surface portion of the final format created by crosslinking. This surface distribution ensures that the larger surface portion can later be effectively bonded to the endpaper of the book block, and non-destructive separation of the cover from the endpaper remains impossible; thus, attempts at tampering can be avoided.

[0012] This creates the possibility of implementing security features by cross-linking the adhesive film in the area of ​​the final format of the cover. In this way, it is advantageous if at least one cross-linked adhesive line and / or at least one cross-linked, particularly dot-shaped, adhesive spot is created in the area of ​​the final format of the cover.

[0013] It is also possible that, to create a security feature, at least one interconnected graphic element is created in the area of ​​the final format of the cover, in particular in the form of a character, a letter, or a character sequence. The graphic elements, the glue lines, and the glue spots will later become tactilely perceptible once the cover has been glued to the endpaper of the book block. There is no gluing in this area. The interconnected graphic elements, the glue lines, and the glue spots will become tactilely or haptically perceptible as embossing.

[0014] The advantages, advantageous embodiments and effects explained in connection with the method according to the invention for producing the pre-laminated blank also apply to the method according to the invention for producing a book-shaped brochure.

[0015] This method for producing a book-shaped brochure, in particular a book-shaped identification, valuables, or security document, comprises the steps of producing a blank, as mentioned above. Further, the steps of applying a front page of a multi-page book block to the adhesive film of the pre-laminated blank, introducing heat into the adhesive film so that the adhesive film crosslinks with both the blank and the endpaper in those areas where it was previously uncrosslinked, and cutting the blank glued to the book block to the final format of the cover.

[0016] 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 pre-laminated blank apply equally to the blank of a cover according to the invention.

[0017] This inventive blank for a cover for a book-shaped brochure, in particular for a book-shaped identification, valuables, or security document, is pre-laminated with an adhesive film. The blank has dimensions that correspond to the dimensions of the final format of the cover plus a trim allowance surrounding the final format. The adhesive film is cross-linked at least in sections in the area of ​​the trim allowance and uncross-linked at least in sections in the area of ​​the final format of the cover. Thus, an adhesive film based on a "single-reacting" adhesive film can also be used here.

[0018] In order to ensure that the cover is reliably connected to the endpaper of the book block and that these can only be separated again by destruction, it is advantageous if the uncrosslinked area in the area of ​​the final format is larger than the crosslinked area in the area of ​​the final format created by the crosslinking.

[0019] It has proven advantageous if the adhesive film is cross-linked in the area of ​​the trim allowance in the form of an adhesive line or in the form of adhesive dots. This allows the adhesive film to be cross-linked point-by-point or line-by-line in the area of ​​the trim allowance.

[0020] In order to avoid or expel air pockets between the adhesive film and the cover when folding the pre-laminated blank, it has proven advantageous if several of the cross-linked adhesive lines are present in the area of ​​the trim allowance, leaving at least one uncross-linked passage between an outer edge of the blank and in the area of ​​the final format.

[0021] In order for the cross-linking in the area of ​​the final format of the cover to remain perceptible as a later security feature or embossing, it has proven advantageous if at least one cross-linked adhesive line and / or at least one cross-linked, in particular dot-shaped, adhesive spot and / or at least one cross-linked graphic element, in particular in the form of a character or in the form of a letter or in the form of a character string, is present in the area of ​​the final format of the cover.

[0022] The advantages, advantageous embodiments and expedient further 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, as well as the advantages, advantageous embodiments and expedient further developments and effects explained in connection with the blank according to the invention also apply to the cover according to the invention.

[0023] This cover of a book-shaped brochure comprises a blank cut or trimmed to the final format of the cover, as explained above.

[0024] The advantages, advantageous embodiments and expedient further 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, the advantages, advantageous embodiments and expedient further developments and effects explained in connection with the blank according to the invention and the cover also apply to the book-shaped brochure according to the invention, in particular to a book-shaped identification, value or security document which is provided with an above-mentioned cover.

[0025] It is generally noted that all features disclosed with respect to specific aspects or embodiments of the invention can also be combined with other aspects or embodiments of the invention in a technically reasonable manner. This also applies across different technical subject matters and subject matter categories. In particular, this also applies in part to individual features, unless explicitly stated herein or it is obvious from a technical contradiction that an inextricable functional-technical connection exists between certain features, which must be maintained to implement the invention.

[0026] The invention is explained below using an exemplary embodiment and its outline. Herein: Figure 1 shows a perspective view of a book-shaped identification, value or security document; Figures 2a) to 2f) show process steps for producing the book-shaped identification, value or security document from Figure 1 ; Figure 3 a plan view of a pre-laminated blank of a cover, which is provided with glue points only in the area of ​​the trimming allowance; and Figure 4 one of the Figure 3 corresponding top view of a pre-laminated blank cover, which is additionally provided with adhesive points in the area of ​​the final format of the cover.

[0027] In Figure 1A book-shaped identification, valuables, or security document 100 is shown. The identification, valuables, or security document 100 is, for example, an identification document, in particular a passport or identity card. The identification, valuables, or security document 100 has a cover 102 and a passport book block 104 held in the cover 102. The passport book block 104 consists of a data card 106, several passport book pages 108, an endpaper 110, and a binding band 112, which are connected to one another by a seam 114.

[0028] The data card 106 is a plastic- or paper-based card on which person- and / or document-specific information is applied. For example, the data card 106 can have a passport photo 116 and personal 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, valuable, or security document 100. The data card 106 further has a chip in which person- and / or document-specific information can be stored. In particular, the chip has a secure memory area for storing the person- and / or document-specific information.Furthermore, the data card 106 may have visible and / or invisible security features that prevent counterfeiting of the data card 106.

[0029] A particularly flexible tab 120 made of an endless belt is provided on the data card 106. The endless belt consists of a fabric that can be coated and / or sheathed with a flexible plastic material. The tab 120 is attached to the data card 106 in a form-fitting and / or material-fitting manner and thus becomes part of the data card 106. Additional security features can be provided on the tab 120.

[0030] The passport book pages 108 are cut from a printed sheet, preferably a sheet of paper, and folded along their centerline 122. The passport book pages 108 can be printed, for example, with additional personal and / or document-specific information, page numbers, or other information. In the case of the German passport, these personal and / or document-specific data and information under numbers 11 to 14 will be printed or applied to the first or the first passport book pages 108. The passport book pages 108 can furthermore be prepared to receive stamps, for example, visa stamps. Preferably, the passport book pages 108 also contain security features that prevent forgery of the passport book pages 108. The security features can, for example, be printed, incorporated into the passport book pages 108, or incorporated into them.For example, the passport book pages 108 contain a perforation, wherein the perforation preferably tapers conically through the passport book pages 108.

[0031] The endpaper 110 forms the outer end of the passport book block 104. The passport book block 104 is glued to an inner side 126 of the cover 102 with an outer side 124 of the endpaper 110.

[0032] The folding tape 112 serves as reinforcement of the seam area and is glued to the outer side 124 of the endpaper 110 before the passport book block 104 is sewn.

[0033] The production of the identification, valuables or security document 100 is described below using the Figures 2a to 2f be described.

[0034] In a first method step, the data card 106 is provided and the tab 120 is attached to the data card ( Figure 2a). The tab 120 is connected to the data card 106 in an overlapping area 121 in a form-fitting and / or material-fitting manner and cut to the desired length.

[0035] The binding tape 112 is then applied to the seam area of ​​the endpaper 110 and the passport book block 104 consisting of the passport book pages 108, the data card 106 and the endpaper 110 is assembled ( Figure 2b ). The data card 106 is inserted into the passport book block 104 such that the flap 120 is arranged in the seam area.

[0036] The passport book block 104 is then sewn with a seam 114 along the center line 122 of the passport book pages 108 ( Figure 2c ).

[0037] After or simultaneously with the sewing of the passport book block 104, a blank cover 102 is prepared. The inner side 126 of the blank cover 102 is glued to the outer side 124 of the endpaper 110, and the resulting passport book blank 128 is folded ( Figures 2d and 2e ).

[0038] Subsequently, the free edges of the passport book blank 128 are processed and thus the passport book blank 128 is cut to the final format of the identification, valuables or security document 100 ( Figure 2f ).

[0039] The present invention is concerned with the provision of the cover 102, in particular with the application of an adhesive layer to the cover 102 of the identification, value or security document 100.

[0040] The present invention relates to the application of an adhesive film 132 to a blank cover 102, which can then be cut to size. The adhesive film 132 has the property of being a single-reacting adhesive film that develops adhesive properties and immediately crosslinks at the same temperature.

[0041] In Figure 3 is shown the blank of a cover 102 for a book-shaped brochure, in particular for an identification, valuables or security document 100. Here, an unlaminated blank with predetermined blank dimensions was provided, which correspond to the dimensions of a final format 132 of the later cover 102, which in Figure 3shown in dashed lines, plus a trim allowance 134 surrounding the final format 132, which is shown hatched here. Within this trim allowance 136, the adhesive film 130 is cross-linked only in certain areas by applying heat. As a result, the adhesive film 130 adheres to the blank of the cover 102 in the area of ​​the trim allowance 134. However, in the area of ​​the final format 132 of the cover 102, the adhesive film 130 remains uncross-linked in some sections. The dotted line shows the later folding line for the brochure, thus for the later identification, valuables, or security document 100.

[0042] It can be seen that in the area of ​​the trim allowance 134, the heat input for crosslinking the adhesive film 130 was linear, so that several crosslinked adhesive lines 136 were created in the area of ​​the trim allowance 134. Furthermore, between each two of the adhesive lines 136 there is at least one uncrosslinked opening 138 between an outer edge of the blank and the area of ​​the final format 132 of the cover 102, so that when folding along the dotted line, air that is still between the blank and the adhesive film 130 can escape through these openings 138. The adhesive line 136 has a width corresponding to approximately 1 mm in this case, because this ensures that there is a sufficient area for bonding during later crosslinking with the book block, thus with the endpaper 110.

[0043] Figure 4refers to the possibility that heat can also be introduced into the adhesive film 103 in sections in the area of ​​the final format 132 of the cover 102. The non-crosslinked surface portion of the final format 132 of the cover 102 is larger than the crosslinked surface portion of the final format 132 created by crosslinking. In the present case, in the area of ​​the final format 132 of the cover 102, there is a pair of crosslinked adhesive lines 140 that are arranged symmetrically with respect to the dotted fold line. This arrangement is selected such that the folding band 112 is projected outwards on the book cover at precisely this location in the finished book, whereby the transition from the folding band 112 to the cover 102 can be optically concealed in this way or can also be perceived as a precisely defined, visible line.In addition, the optional possibility is shown that in the area of ​​the final format 132 of the cover 102 at least one cross-linked, in particular point-shaped adhesive spot 142 is produced, which is later perceptible in the glued state, for example as embossing.

[0044] Furthermore, the optional possibility of generating at least one interconnected graphic element 144, such as a logo, in the area of ​​the final format 132 of the cover 102 is shown. This graphic element 144 can also be in the form of a character, in the form of a letter or - as shown merely by way of example in Figure 4 shown - in the form of a character string.

[0045] This configuration ensures that only a small portion of the final format 132 is provided with an adhesive film 130, which is already cross-linked before the endpaper 110 is glued to the blank of the cover 102. Due to the selected surfaces, which will later be cross-linked to the endpaper 110, it is ensured that the largest surface portion of the cover 102 is bonded to the endpaper 110 by the adhesive. A non-destructive separation of the cover 102 from the endpaper 110 is therefore no longer possible. After gluing the pre-laminated blank of the cover 102 to the book block, in particular to the passport book block 128, the book-shaped brochure thus formed, in particular the book-shaped identification, valuables, or security document 100, is trimmed to its final size.

[0046] The solution according to the invention ultimately makes it possible to use simpler materials for the adhesive film 130, particularly those that develop and crosslink adhesion properties in only one step. This reduces the process time for producing book-shaped brochures, particularly book-shaped identification, valuables, or security documents 100. Furthermore, there is a lower degree of contamination, since liquid adhesive is no longer required. List of reference symbols
