Insert, book block and book-like document and method for producing an insert, book block and book-like document

Description

[0001] The invention relates to a method for producing an insert sheet, a method for producing a book block for a book-like document as well as a book-like document, and an insert sheet, book block and book-like document produced according to this method.

[0002] A passport book with an insert sheet is known from WO 2006 / 079224 A1. Such an insert sheet consists of two flexible plastic layers with a flap sandwiched between them. A folded area extends along the flap, which also contains a seam. The insert sheet is sewn together with inner pages and a book cover to form a passport book. The data page area of ​​such an insert sheet consists of PC layers. Since these PC layers cannot be sewn, or can only be sewn with difficulty, the flap is made of a woven fabric to allow for a seam to be created with a special thread. Manufacturing such a passport book is complex. Furthermore, using thread for the seam increases the risk of tampering.

[0003] From WO 2014 / 040825 A1, a book-like document is known which has a book cover with several data pages, wherein the data pages are permanently connected, at least partially, by welding or laminating in the fold area of ​​the book cover. This book-like document comprises a personalization data page with a flap, which are separated by a fold edge and form a fold area. The flap of the data page extends completely along the long side of the data carrier. From WO 2010 / 097226 A1, an insert sheet for a book-like document is disclosed. This insert sheet comprises a data page and a flap attached to it by a fold area. The length of the flap extends over the entire length of the data page.

[0004] From EP 1 502 765 A1, a book-like document with an insert sheet is also known. This insert sheet comprises a data page and a flap, the length of which corresponds to the length of the data page. In the fold area of ​​the insert sheet, it is sewn to the data pages and the book cover.

[0005] WO 2014 / 056483 A1 discloses a book-like security and / or valuation document in which individual data pages are provided without a flap. Instead, these individual data pages are directly bound into a spine made of elastomeric material.

[0006] The invention is based on the objective of proposing a method for producing an insert sheet that can be connected to a book block and / or a book-like document without sewing and is easy to manufacture. Furthermore, the invention is based on the objective of proposing a method for producing a threadless book block and a book-like document with an insert sheet, as well as an insert sheet, a book block, and a book-like document.

[0007] The problem underlying the invention is solved by a method for producing an insert sheet for a book-like document according to the features of claim 1. The introduction of at least one open-edged recess represents a simple method for producing the at least one flap section as a connecting element for attaching the insert sheet in a book block or book-like document.

[0008] In a preferred embodiment of the method, several tab sections are formed along a longitudinal edge of the data page, the lengths of which are the same or different along the longitudinal edge of the data page, or partially the same or different. This assigns a specific dimension to each tab section with respect to its length, thus enabling a kind of personalization via the tab length of the tab sections, which makes manipulation more difficult.

[0009] Furthermore, the cutouts formed between the flap sections preferably have the same or different lengths, or a combination thereof. This allows for a specific pattern for each insert sheet to be arranged side by side, even with flap sections of the same size.

[0010] The edges of the flap sections preferably extend at right angles to the fold area or the long edge of the data page. This facilitates a simple die-cutting process. Alternatively, the edges of the flap section can be designed so that they point towards each other at the free end. This allows for easy threading and insertion of the flap sections into corresponding openings in the inside and / or the book cover. As the flap sections are inserted and passed through the openings in the inside and / or recesses in the book cover, the insert sheet is centered on the inside and / or the book cover.

[0011] Preferably, at least one layer or at least one further layer of the insert sheet is made of a thermoplastic material, in particular PE (polyethylene), PC (polycarbonate), Pl (polyimide), PA (polyamide), PET (polyethylene terephthalate), or a mixture thereof. In particular, the insert sheet can have a monolithic structure, with PC preferably being used for the fabrication and construction of the data side, at least for the outer layers, wherein one layer extends beyond the data side and forms the flap. The at least one layer or at least one further layer of the insert sheet can consist of one or more individual layers that are joined together by lamination, bonding, or welding.Furthermore, the at least one first layer or the at least one further layer of the insert sheet can consist of a textile, woven fabric, nonwoven, felt, paper, plastic-impregnated paper, or the like. It is also preferably possible that the individual materials can be combined to create a specific layer structure. For example, the at least one first layer can consist of paper, plastic-impregnated paper, or paper coated with plastic, and the at least one further layer applied to it, which in particular forms the data side, can consist of, for example, polycarbonate.

[0012] Furthermore, it is preferably provided that the flap sections are of uniform width. The width of the flap sections is determined by a distance from the long side of the data page to the free end of the flap section. This ensures a uniform connection of the flap sections of the insert sheet to the closure element.

[0013] The object underlying the invention is further solved by a method for producing a book block according to the features of claim 7, in particular for a book-like document, in which at least one inner page, in particular as a double page, is provided and an opening corresponding to the flap section is made along a fold area of ​​the at least one inner page, the length and distance of which are matched to the front face of the data page, so that after the at least one opening is made, the at least one flap section of the insert sheet is passed through the opening of the inner page and subsequently the flap section is bent over and brought to rest against the outer surface of the outer inner page and is thus firmly connected, or a closure element is attached to the flap section that projects freely from the fold area of ​​the outer inner page.to secure the flap section to the fold area of ​​at least one inner side. This manufacturing process makes it possible, in particular, to use the same materials, at least for the flap of the insert sheet and the closure element, thus avoiding the need for a change that would lead to high manufacturing costs. Especially when using the same material for the flap section and the closure element, a monolithic connection can be created.

[0014] The object underlying the invention is further solved by a method for producing a book-like document according to the features of claim 8, which consists of an insert sheet, at least one inner page and a book cover, wherein an insert sheet with at least one flap section is provided, wherein at least one opening is provided in the fold area of ​​the at least one inner page which corresponds in length and position to the at least one flap section towards the front face of the data page, wherein at least one recess is provided in the fold area of ​​the book cover which corresponds in length and position to the at least one flap section towards the front face of the data page,in which at least one flap section of the insert sheet is passed through the corresponding opening and recess, and in which a closure element is attached to at least one flap section protruding from the recess of the book cover, and the at least one inner side and the insert sheet are fixed to the book cover. This allows for the production of a book-like document of value through simple and therefore cost-effective process steps. This document is threadless and preferably also has the advantage of being easy to open and close without slamming shut. Furthermore, the material used to form the data page can simultaneously serve as the flap material for binding the insert sheet into a book-like document, since a threadless arrangement is provided.

[0015] Preferably, the closure element is welded, bonded, laminated, thermoformed, solvent-bonded, or injection-molded to the at least one tab element. Welding can be achieved, for example, through thermal bonding or ultrasonic welding. Bonding can involve one- or multi-component adhesives, hot melt adhesives, or similar materials. Thermoforming can utilize a temperature-controlled press tool. Furthermore, a plasticizer can be applied to the strip-shaped closure element and / or the tab section using a solvent, thereby bonding them together. Similarly, injection molding can create a uniform, material-bonded connection between the tab sections and the injection-molded closure element.To support a material-bonded connection between the closure element and the at least one tab section, the at least one tab section and the closure element can be structured and / or have perforations.

[0016] Furthermore, preferably after the closure element is connected to the at least one flap section, the book cover, the at least one inner page, and the insert sheet are die-cut to a final format. Preferably, if at least one flap section extends beyond the closure element, this is also cut off. This allows a final manufacturing step for the completion of the book-like document to take place after the closure piece has been attached.

[0017] The object underlying the invention is further achieved by a method for producing a book-like document according to the features of claim 11, comprising an insert sheet, at least one inner page, and a book cover, wherein an insert sheet with at least one flap section is provided, wherein at least one opening is provided in the fold area of ​​the at least one inner page, which corresponds in length and position to the at least one flap section towards the front face of the data page, and wherein at least one recess is provided in the fold area of ​​the book cover, which corresponds in length and position to the at least one flap section towards the front face of the data page.in which at least one flap section of the insert sheet is passed through the corresponding opening and recess, and in which a closure element is attached to at least one flap section protruding from the recess of the book cover, and the at least one inner side and the insert sheet are fixed to the book cover. This allows for the production of a book-like document of value through simple and therefore cost-effective process steps. This document is threadless and preferably also has the advantage of being easy to open and close without slamming shut. Furthermore, the material used to form the data page can simultaneously serve as the flap material for binding the insert sheet into a book-like document, since a threadless arrangement is provided.

[0018] This problem is solved by an insert sheet according to the features of claim 12, which has at least one layer of a thermoplastic material with a data side and a flap arranged thereon, which extends along a longitudinal side of the data side and forms a fold area adjacent to the data side, wherein the data side and the flap are formed from the at least one layer or the flap is formed as a further layer provided on the at least first layer, and the flap has at least one open-edged cutout which extends from the free end of a longitudinal edge of the flap to the data side and divides the flap into at least two flap sections, and the flap comprises a flap section which is shortened in length compared to the longitudinal edge of the data side.This at least one tab section, which adjoins one long edge of the data page, represents the connecting element to join the insert sheet with at least one inner side to form a book block or to join the insert sheet and at least one inner side with a book cover to form a book-like document, without the need for a sewing thread.

[0019] The problem underlying the invention is further solved by a book block according to the features of claim 13, which consists of an insert sheet with at least one flap section and at least one inner side, wherein the inner sides are in particular designed as a double page which are folded along a fold area.Along the fold area, at least one elongated opening is provided, corresponding in length and distance to the end face of the data page or the adjacent flap section, so that the at least one flap section is passed through the corresponding opening to position the insert sheet towards the inside. The at least one flap section freely projecting from the opening of the outer inside page is firmly connected to an outer surface of the inside page, or to an outer surface of an endpaper surrounding the at least one inside page, or is fixed to the inside page by a closure element. This allows a book block with an insert sheet and at least one inside page to be created, which is manufactured without sewing thread. The book block can also include the endpaper.The connection between the insert sheet and the inner pages and / or endpaper is formed by at least one tab section, which is passed through openings in at least one inner page and then firmly attached to an outer surface of the outermost layer of the inner page or endpaper. Alternatively, the fastening element can secure the at least one tab section to the outer surface of the outermost layer of the inner page or endpaper by preventing it from being pulled out of the opening on the inner page. The at least one tab section passing through the fastening element creates a kind of hinge between the fastening element and the outermost inner page or endpaper, allowing the fastening element to also rest against an outer surface of the outermost inner page.This allows the inside pages to be easily opened without them closing automatically.

[0020] Preferably, the at least one flap section, which passes through the opening in the inner surface and protrudes freely, is connected to the outer surface of the inner surface by gluing, welding, or fusing. This allows for simple fixation and formation of the book block from the at least one inner surface and the insert sheet. Alternatively, the at least one flap section can be connected to the closure element by laminating, gluing, welding, injection molding, thermoforming, or thermal solvents. Depending on the intended use of such a book block, the closure element and its connection to the at least one flap section can be selected accordingly.

[0021] The object underlying the invention is further achieved by a book-like document according to the features of claim 15, comprising a book cover with at least one inner page, preferably designed as a double page, and an insert sheet, wherein the insert sheet, the at least one inner page, and the book cover are connected to one another by the at least one flap section arranged on the insert sheet. The at least one flap section of the insert sheet is passed through a corresponding opening in the fold area of ​​the at least one inner page and through a further corresponding recess in the book cover, and the at least one flap section is connected to the closure element outside the book cover.The flap section, formed on the insert and acting like a kind of sword, extends through the opening in at least one inner page and the recess in the book cover. After the closure element is attached, this flap section creates a hinge-like connection between the closure element and the book cover, allowing for easy opening and closing. Simultaneously, the inner page and the book cover can be easily opened without closing on their own and then securely folded together.

[0022] Preferably, the fastening element is band-shaped and extends along the fold of the book cover. This allows for uniform securing of the flap section along the fold when only one flap section is formed. If multiple flap sections are present, they can be held together by the band-shaped fastening element. The fastening element can also be designed as a clamp or a slotted round bar.

[0023] Furthermore, it is preferably provided that the closure element consists of a thermoplastic material and in particular of the group consisting of PC (polycarbonate), PET (polyethylene terephthalate), and its modifications, in particular PET-G and PET-F, polyacrylates, in particular PMMA (polymethyl methacrylate), ABS (acrylonitrile butadiene styrene), PE (polyethylene), PP (polypropylene), Pl (polyimide or poly-trans-isoprene), PVC (polyvinyl chloride) and copolymers, as well as block copolymers, such polymers and co-extruded materials made from these polymers.

[0024] The invention, as well as further advantageous embodiments and developments thereof, are described and explained in more detail below with reference to the examples shown in the drawings. The features that can be derived from the description and the drawings can be applied individually or in any combination according to the invention. The drawings show: Figure 1a schematic side view of a book-like security document, Figure 2 a schematic sectional view of the book-like security document according to Figure 1 along line II-II, Figure 3 a schematic side view of an open book-like document according to Figure 1 , Figure 4 a schematic view of an insert sheet, Figure 5 a schematic sectional view of the insert sheet according to Figure 4 along the VV line in Figure 1 , Figure 6 a schematic view of an open inside page, Figure 7 a schematic side view of several inside pages and an insert sheet according to Figure 4 in an intermediate step during the production of a book block, Figure 8 a schematic view of a first embodiment of a book block, Figure 9 a schematic view of another embodiment of the book block Figure 8 , Figure 10a schematic side view of an alternative embodiment of a book block Figure 8 and Figure 11 a schematic side view of an alternative embodiment to Figure 2 .

[0025] In Figure 1 Figure 11 shows a schematic side view of a book-like document. Figure 2 is a schematic sectional view along line II-II in Figure 1, and Figure 3 The book-like document 11 shows according to Figure 1 in a served position.

[0026] This book-like document 11 could, for example, be an identification document such as a passport. This document 11 comprises a book cover 12. The book cover 12 contains at least one inner page 14, which is preferably designed as a double page. In addition, the book cover 12 contains an insert sheet 15, which comprises a data page 17. This data page 17 can, as shown in Figure 4The document is depicted, for example, as being designed according to the ICAO standard and comprising an image 19 of the document holder, an OCR-readable ICAO zone 21, and further personalization data 22. The personalization data 22 is provided within the data page 17. This data page 17 has a flap 23 with at least one flap section 24, by which the insert sheet 15 and at least one inner page 14 are fixed to the book cover 12 to form the book-like document 11.

[0027] In Figure 5 schematically, a sectional view along line IV-IV in Figure 4The data page 12 comprises at least a first layer 26, which, for example, forms a back cover, and a second layer 27, which, for example, forms a front cover. An additional layer 28 may be provided between these layers, which, for example, contains the personalization data 22 and the image 19. Furthermore, a transponder module (not shown in detail), consisting of an IC chip and an antenna, may be provided between the first and second layers 26 and 27. Additional electronic or other security elements, in particular the fractive security elements, may also be incorporated into the additional layer 28 or between layers 26 and 27. The data page 17 preferably has a closed circumferential edge, which is preferably produced by laminating, fusing, welding, or the like.

[0028] With regard to a possible structure of such an insert sheet, full reference is also made to DE 10 213 103 353 A and / or DE 10 2009 010 800 B3.

[0029] Preferably, for example, the first layer 26 extends beyond the data side 17 and forms the tab 23. Alternatively, the tab 23 can be formed by a separate layer which is applied between the first and second layers 26, 27, or at least partially overlapping the first or second layer 26, 27, or extending completely along these layers 26, 27.

[0030] This first layer 26 can, for example, consist of a single layer, such as polycarbonate, and have a thickness such that the tab 23 and the data side 17 attached to it are rigid. Alternatively, several layers can form a first layer 26 in which the tab 23 is rigid. It is also possible for the first layer 26 to consist of one or more layers, with the tab 23 being flexible and, for example, able to be angled or bent relative to the longitudinal edge 29 of the data side 17.

[0031] A fold area 31 extends along a longitudinal edge 29 of the data side 17. This fold area is narrower than or equal in width to the flap 23. Flap sections 24 are formed extending from a longitudinal edge 29 of the data side 17. These flap sections are formed, for example, from a continuous section of layer 26 forming the flaps 23, with open-edge recesses 32. The dashed line represents the initial state and the presence of layer 26 before the open-edge recesses 32 are created using a punching or cutting tool.

[0032] Preferably, the length 24a of each flap section 24 differs along the longitudinal edge 29 of the data side 17. Additionally, it is advantageously provided that the open-edge recesses 32 also differ in length or spacing between the flap sections 24. The flap sections 24 preferably all extend the same distance from a free end 34 of the respective flap section 24 to the longitudinal edge 29 of the data side 17. This distance forms the width 23a of the flap section 24. The open-edge recesses 32 create a complete break along the fold area 31.

[0033] According to an alternative embodiment, only one tab section 24 may be provided, which, for example, is flush with one end face 36 of the data side 17 and has a recess 35 on the opposite end face 37, or the recess 35 may be reversed. Likewise, the length 24a of the tab section 24 may be recessed on both sides relative to the end faces 36 and 37 of the data side 17, or may be formed with a recess 35, meaning that the length 24a of the tab section 24 is shortened relative to the longitudinal edge 29 of the data side 17.

[0034] A safety element can be created by the sequence of the tab sections 24 with respect to their length 24a and the length of the edge-open recesses 32, which can be selected and assigned to each other in a specific way.

[0035] In Figure 6Figure 1 shows a schematic view of the inside 14 in unfolded form. Openings 41 are provided along the fold area 31, their length and spacing adapted to the tab sections 24 provided on the insert sheet 15. These openings 41 are made using a punching or cutting tool, in particular a laser cutting beam, which allows for precise alignment of the openings with the inside and thus alignment of the insert sheet 15 with the inside 14. Advantageously, the openings 41 are only slightly larger than the length and thickness of the tab sections 24.

[0036] In Figure 7Figure 1 shows a schematic side view in which, for example, three inner sides are positioned and received by the tab sections 24 into the insert sheet 15. The tab sections 24 penetrate the openings 41 of the inner sides 14 and receive them. The innermost inner side 14 rests against the longitudinal edge 29 of the data side 17. In other words, the insertion movement of the tab sections 24 of the insert sheet 15 is limited by the longitudinal edge 29.

[0037] To complete a book block of 45, for example, according to Figure 8The portion of the tab sections 24 projecting beyond the inner surface 14 is bent over and attached to an outer surface 43 of an outer inner surface 14. The inner surfaces 14 are usually made of paper, so adhesive bonding can be used. If the inner surface 14 has an outer layer of plastic, the tab sections 24, which are preferably made of thermoplastic material, can also be bonded, welded, fused, or otherwise joined.

[0038] This schematic side view shows a book block 45 that can be placed in a book cover to form a book-like document 11.

[0039] The in Figure 9 The alternative embodiment of book block 45 shown differs from the embodiment according to Figure 8in that the inner side 14 is surrounded by an endpaper 52. At least one flap section 24 of the insert sheet 15 is preferably fixed to an outer surface 43 of the endpaper 52. To insert such a book block into a book cover, the outer surface 43 of the endpaper 52 is glued to an inner surface of the book cover 12, thereby binding the book block 45 into the book cover 12 and forming a book-like document 11.

[0040] At the in Figure 9 In the alternative embodiment shown, it can also be provided that a part of the tab sections 24 is fixed to the outer surface 43 of the outermost inner surface 14 and another part of the tab sections 24 is fixed to the outer surface 43 of the attachment 52.

[0041] In Figure 10 is an alternative embodiment of a book block 45 to Figure 8As shown, in this embodiment, the tab sections 24 projecting outwards beyond the outer inner surface 14 are secured by a locking element 47, thereby preventing the insert sheet 15 from being detached from the inner surface 14. The locking element 47 is, for example, designed as a strip-shaped band, with only one band engaging an outer surface of the tab sections 24. Alternatively, two opposing bands can be provided, with the tab sections 24 positioned between them. The band-shaped locking element 47 preferably consists of a thermoplastic material that is identical or very similar to that of the tab sections 24. This allows a monolithic connection to be advantageously created by lamination, welding, solvent application, or thermal forming to secure the insert sheet 15 and the inner surface 14 to each other.This creates a 45-page book block without sewing thread.

[0042] The closure element 47 advantageously extends over the entire length of the longitudinal edge 29 of the insert sheet 15. Between the closure element 47 and the fold area 31 of the inner side 14, the tab sections 24 remain as webs and thus form a hinge-like arrangement 48, so that the closure element 47 can also be folded laterally relative to the inner sides 14.

[0043] After the closure element 47 has been attached, the book block 45 can be die-cut to a final format, which is indicated by the dashed lines. Simultaneously or subsequently, the areas of the flap sections 24 extending beyond the closure element 47 can also be cut off.

[0044] The in the Figures 7 and 10The described arrangement of the insert sheet 15 with the at least one flap section 24 and the closure element 47 attached thereto applies analogously to the structure of the book-like document 11 according to the Figures 1 to 3 This construction differs further in that the book cover 12 comprises recesses 49 which correspond to the openings 47 of the inner surface 14, so that in a first step to join the insert sheet 15, the inner surface 17 and the book cover 12, preferably the at least one opening 41 and the at least one recess 49 are aligned congruently, so that the at least one flap section 24 of the insert sheet 15 can be inserted. This aligns and positions the inner surfaces 17 and the book cover 12 relative to each other and to the insert sheet 15 via the flap section(s) 24. Subsequently, the closure element 47 is attached. In this embodiment, as with the book block 45, Figure 9 a hinge-like arrangement 48 was formed.

[0045] At the in Figure 2 In the sectional view shown, for example, the locking element 47 differs from the one in Figure 10 It is manufactured by injection molding and partially incorporates the protruding areas of the tab sections. Furthermore, the areas are cut off after the fastening element 47 is attached, as shown by the dashed lines.

[0046] In the Figures 1 and 2 In the book-like document 11 shown, the closure element 47 can also be formed from one or two strip-shaped layers, in particular PC layers, which can be connected to the flap sections 24 by gluing, welding, fusing or the like.

[0047] At the in Figure 2In the illustrated embodiment, it is preferably provided that the book-like document has a symmetrical structure, wherein the insert sheet 12 is arranged in the middle and the same number of double pages of the inner pages 14 are provided to the left and right of it.

[0048] In Figure 11 is an alternative embodiment of a book-like document 11 to Figure 2The illustration is shown in cross-section. In this embodiment, the inner sides 14 are sewn together to form a book block 45. In an outermost inner side 14, adjacent to the seam 51, at least one opening 41 is provided to insert the insert sheet 15. The insert sheet 15, with its at least one flap section 24, penetrates both the at least one opening 41 of the inner side 14 and the at least one recess 49 of the book cover 12, so that the closure element 47 can be attached again outside the book cover 14. In this embodiment, the outer surfaces 43 of the outermost inner side 14 are preferably glued to the book cover 12 and form the endpaper 52. Reference number list
