Description

The invention relates to a flap for a data page, a data page for a book-like document and a method for producing the same.DE 10 2012 112 383 A1 discloses a method for producing a data page for a book-like document, in which the data page comprises a data carrier and a flexible tape material arranged thereon as a tab, which are non-detachably connected to one another in an overlap region. This flexible tape material is provided as an endless belt and is fed to the data carrier by a feed device in order to connect the flap to the data carrier in order to form the data page.WO 2015 / 177440 A1 discloses a book-like document with a data page, which document comprises a data carrier and a flexible tape material arranged thereon as a flap. The data page is made of a plastic material such as polycarbonate. The flap is made of a sheet-like plastic material, such as polyurethane. The tab is connected to the data page in the overlap region by ultrasonic welding. In this case, a plurality of joining points arranged in a row and spaced apart from one another is formed in the overlap region. In these joining points, the tab is welded to the data side.Furthermore, DE 10 2013 103 353 A1 discloses a data page, in particular a personalization data page, for a book-like document, in which a tab is connected to the data carrier, said tab consisting of a fabric-shaped strip material made of a polymer material. The data carrier consists at least of one layer of polycarbonate.DE 10 2015 118 227 A1 discloses a data page for a book-like document and a method for producing the same. The data page comprises at least one individual page for applying and / or storing data and at least one flexible tab which is connected to the at least one individual page in an overlap region and which comprises a free tab region projecting beyond it, wherein a tab section of the at least one tab element is arranged on an upper side and on an underside of the data page in each case in the overlap region and is connected to the upper side and underside of the data page.EP 3 275 683 A1 discloses a data page and a method for the production thereof. The data page comprises a data carrier consisting of at least one layer and a flap made of a textile tape material, which are connected to one another to form an overlap region, wherein a region of the flap opposite the data carrier and emerging from the overlap region, which region is bounded by a free flap edge, is folded over and a seam is formed with at least one fold-in.DE 10 2012 213 913 A1 and DE 10 2016 218 040 A1 describe in more detail a method for producing an overlap region with an ultrasonic welding device on a data carrier with a tab made of a textile material.WO2007 / 054618 A1 furthermore discloses a security document as a data page with a flap, in which the flap consists of a textile material. The tab is arranged overlapping the data carrier and welded to one another in the overlap region formed in this case, wherein the tab penetrates at least partially into the data carrier.When using a fabric for the flap, there is the risk that the flap may rip out at a cut edge outside the overlap region to the data carrier during prolonged use. Individual protruding weft or warp threads and / or filaments can thereby form points of application for a user in order to pull out individual threads.The object of the invention is to propose a method for producing a tab and a method for producing a data page with a tab from a fabric, as well as a tab and a data page with a tab connected thereto, in which a ripping out of a cut edge of a tab is prevented.This object is achieved by a method for sealing a flap for a data page of a book-like document, in which a band material made of a fabric with warp and weft threads is provided to form the flap and fed to a processing station and one or more sealing surfaces are introduced into the flap in the protruding region of the flap, said sealing surfaces being formed from a plurality of mutually spaced welding points. This introduction of one or more sealing surfaces, which consists of individual welding points, has the advantage that, on the one hand, a raggeding or protrusion of individual threads is prevented and the flexible and tear-resistant properties of the fabric are nevertheless retained. At least one crossing point between a weft and warp thread is welded by the welding point. By incorporating the sealing surfaces with individual welding points, it is made possible that the fabric remains in its original shape and / or shape between the individual welding points. Thereby, the typical yarn properties of the fabric such as flexibility and tear resistance can be maintained.Fabrics based on thermoplastic materials, such as polyesters, polyethylene terephthalate polyamides and acrylates, are very highly drawn in fiber spinning. If these yarns are heated and melted again, these yarns contract very strongly again. In this case, the typical yarn properties are largely lost. However, the at least one sealing surface formed with a plurality of adjacent welding points maintains flexibility and crack resistance.Preferably, the welding points are introduced in a surface grid and form the sealing surface. This has the advantage that a structured configuration of the sealing surface is formed.This structuring can simultaneously also form a security feature. For this purpose, in a further embodiment, the sealing surfaces can consist, for example, of letters, text or characters. Corresponding security features can also be generated in the form of clearances. Consequently, such sealing surfaces can also meet high aesthetic, individual and safety requirements.Preferably, in the sealing surface, a plurality of welding points are aligned with one another in rows and / or columns, by means of which the surface grid is formed. This has the additional advantage that the shrinkage of the tissue is largely reduced because it is fixed in its position during sealing by the applied pressure. Nevertheless, sealing of the individual threads can take place.The surface grid within the sealing surface is preferably formed from a plurality of round, diamond-shaped or square welding points. In this case, the size of the individual welding points can be adapted to the mesh width of the fabric, so that the distance and the structuring of the welding points are adapted to a repeat of the fabric.These welding points can be lined up to form a letter symbol and / or a character string. The welding points can also be designed as a character sequence, symbol sequence and / or character sequence.The welding point of a sealing surface is preferably formed by one or more elevations on a surface structure of an anvil and / or a sonotrode of an ultrasonic connecting tool. As a result, the size of the welding point can be chosen to be flexible.A further advantageous embodiment of the invention consists in using the structured surfaces of sonotrode and / or anvil as a pressure or embossing tool. When used as an embossing tool, printing can be implemented in the region of the sealing surfaces in conjunction with transfer films. When used as a printing tool, colors can be transferred to the fabric in accordance with the surface embossing.A further preferred embodiment of the invention consists in embodying the anvil in the form of a mechanical counter. It is thereby possible to introduce individual or person-related numbers and / or letters into the region of the sealing surface.Furthermore, it is preferably provided that the shape and / or the size of the elevations on the anvil and / or the sonotrode are adapted to the mesh opening of the fabric and at least two warp and weft threads are welded at their crossing points by an elevation. If the welding point is formed only by one elevation, four crossing points are therefore welded to one another. Alternatively, it can be provided that a plurality of mesh openings are welded to their crossing points, that is to say that, for example, four elevations engage in four mesh openings in order, for example, to weld nine crossing points to one another. The number of elevations forms the shape and size of the welding point.Furthermore, it is preferably provided that the surface structure of the anvil and / or the sonotrode has a plurality of elevations, which are arranged in a diamond pattern and preferably this diamond pattern is aligned rotated by 45° with respect to the warp and weft threads of the fabric and the weld point is formed. This has the particular advantage that all fibers and / or filaments along the cut edge of the tab can be gripped by such a seal and welded to one another.Furthermore, the fabric is produced from plastic fibers, in particular monofilaments or from a mixture of textile fibers and plastic fibers. Both a pure woven fabric made of plastic and a mixed woven fabric can be provided for forming the flap.Furthermore, the at least one sealing surface is positioned adjacent to an outer end edge of the tab. This can prevent the tissue from raggeding.Furthermore, it can preferably be provided that a plurality of sealing surfaces are introduced at a distance from one another along an outer front edge of the tab and preferably in each case one sealing surface is positioned in the corner region of the tab. By such an arrangement of a plurality of sealing surfaces, regions between the individual sealing surfaces along the end edge of the flap can also be provided which are not sealed and nevertheless a ripping out can be prevented. Such an arrangement has the advantage that the shrinkage of the fabric is reduced to a barely visible level.Furthermore, the at least one sealing surface is introduced into the tab outside an overlap region which is provided for bonding to a data page.A further preferred embodiment of the method provides that the welding points of the sealing surface are produced with a matted surface of the anvil and / or of the sonotrode. This can enable adaptation to a surface gloss of the fabric. This can be used to optically emphasize or make the sealing surface non-noticeable. Alternatively, the sealing surface may also be adjusted to the gloss on the surface of the fabric which is not sealed.The object underlying the invention is furthermore achieved by a method for producing a data page for a book-like document, which comprises a data carrier and a tab, wherein the tab consists of a fabric and is positioned on the data carrier in an overlapping manner on one side or between two layers of the data carrier, wherein the tab and the data carrier form an overlap region in which the tab and the data carrier are welded at least in sections or laminated to one another and a region of the tab which protrudes freely with respect to the overlap region is formed, wherein a sealed tab according to one of the preceding embodiments is provided and connected to the data carrier to form the data page, or the tab consisting of a fabric is sealed after connection to the data carrier to form an overlap region in the protruding region in which one or more sealing areas are introduced, which is formed from a plurality of mutually spaced welding points.The object underlying the invention is furthermore achieved by a tab for a data page of a book-like document, which tab has a tape material made from a fabric, wherein one or more sealing surfaces are introduced into the fabric, which sealing surfaces consist of a plurality of mutually spaced welding points. By means of such sealing surfaces, which are formed from a plurality of welding points, the textile property of the fabric can be maintained, since individual stitches between the welding points are not thermally treated by the sealing.It is preferably provided that the welding points form a surface grid. This on the one hand allows sealing also in the region of a cut edge, but prevents sealing over the entire surface within the sealing surface, where the yarn properties, such as flexibility and tear resistance, can reduce or even cancel it out.The surface grid of the at least one sealing surface on the tab preferably consists of round, square, diamond-shaped or rectangular welding points. This enables aesthetic effect to be obtained.The welding points for forming the area grid are preferably aligned with one another within a sealing area in rows and / or columns. As a result, a security feature can also be formed at the same time.Preferably, it is provided that a welding point seals at least two warp and weft threads at the crossing points. This allows the smallest size of a welding point to be formed.Further, the tab includes at least one sealing surface positioned adjacent an outer cut edge of the tab. A longitudinal side of the sealing surface preferably extends along an outer cut edge of the tab. As a result, the fibers can be sealed along the cut edge.Preferably, a plurality of sealing surfaces are introduced at a distance from one another along the outer cut edge on the tab. In particular, a sealing surface is provided in the respective corner region of the tab. The individual sealing surfaces along a cut edge can also be positioned at a distance from one another.The sealing surfaces preferably extend only outside an overlap region which is provided for connection to a data carrier. By bonding the tab to the data carrier, the tab is connected in the overlap region by welding or lamination, so that a further seal can thereby be produced in this region.The object underlying the invention is achieved by a data page for a book-like document, in which a data carrier with a flap according to one of the preceding embodiments is welded at least in sections in an overlap region or laminated to one another.The invention and further advantageous embodiments and developments thereof are described and explained in more detail below with reference to the examples illustrated in the drawings.

This book-like document 11 is, for example, an identification document such as a passport. The document 11 comprises, for example, a book cover 12. A data page 17 and one or more inner pages 18 are connected to one another via a seam 16 to form a book block 15. If a book cover 12 and in particular the attachment 14 are provided, this attachment 14 or this attachment 14 together with the book cover 12 can also be connected to the book block 15 by the seam 16. The inner sides 18 of the book-like document 11 can serve, for example, for receiving visa, stamps or other entries. The data page 17 consists of a data carrier 20 and a tab 23 attached thereto. the data page 17, in particular the data carrier 20, can be designed, for example, according to the ICAO standard, in particular according to I-CAO Doc 9303, 7th edition, and can comprise an image 19 of the document holder, an OCR-readable ICAO zone 21 (also called "machine-readable zone" or "machine-readable zone", MRZ) and further personalization data 22. The personalization data 22 are provided within the data carrier 20. The tab 23 of the data carrier 20 extends beyond the seam 16. This flap 23 also comprises a seam region in which the seam 16 is formed. Additionally or alternatively, an adhesive and / or welded connection can also be provided with the seam 16 in order to bond the flap 23 into the book-like document 11, in particular the book block 15.FIG. 2 schematically shows a view of the data page 17. The data carrier 20 can comprise, for example, a transponder module 24, which consists of an IC chip 25 and an antenna 26. In addition or alternatively, further electronic and / or other security elements, in particular diffractive security elements, can be applied and / or introduced.The tab 23 is connected to the data carrier 20 to form an overlap region 30. The flap 23 consists of a textile strip material which is preferably joined by welding to an outermost layer or layer of the data carrier 20. With regard to the connection of the strap 23 of the textile strip-shaped material for the strap 23 as well as the data carrier 20 as well as the structure of the data carrier 20, reference is made in its entirety to DE 10 2012 213 913 A1.The tab 23 has a region 31 protruding beyond a longitudinal side 41 of the data carrier 20. Within this protruding region 31, the data page 17 is linked to the inner sides 18 for a book block 15.The data carrier 20 has an upper and lower front edge 35, 36. In each case, an end face 37, 38 extending along the tab 23 is preferably aligned with the end face 35, 36 of the data page 17. a sealing surface 39 is provided adjoining the respective end face 37, 38 of the tab 23. This sealing surface 39 in the edge region of the flap 23 in each case creates a sealed edge section which can extend partially or over the entire width of the flap 23 or the length of the end face 37, 38. This sealing surface 39 can be equal to or narrower than the width of the tab 23 or the length of the end edge 37, 38 with respect to the width. The two sealing surfaces 39 arranged on the respective outer edge section of the tab 23 extend at least partially towards one another along a longitudinal side 42 of the tab 23. One or more portions of the sealing surfaces 39 may extend and be provided along the longitudinal side 42 of the tab 23. The formation of the sealing surface 39 is preferably provided in the protruding region 31 of the tab 23. In the protruding region 31, a sealing surface 39 can be formed both on the upper side or front side and on the lower side or rear side of the tab 23. These can also be aligned mutually and offset with respect to one another.According to a first embodiment, the seam 16 is provided for connecting the data carrier 20 to the book block 15 or cover 12 in the protruding region 31 between the longitudinal side 41 of the data carrier 20 and the at least one sealing surface 39. Similarly, the seam 16 may be provided adjacent the sealing surface 39.FIG. 3 shows a schematic view of the data page 17 according to an alternative embodiment to FIG. 2. In this embodiment, the seam 16 is provided in the protruding region 31 in such a way that the seam 16 also extends within the at least one sealing surface 39.FIG. 4 shows a schematic sectional view along the line II-II in FIG. 2 according to a first exemplary structure of the data page 17 before lamination. After lamination, all layers or layers of the data carrier 20 and the tab 23 are connected to one another to form a data page 17, so that a monolithic construction is provided.The data carrier 20 comprises a front side booklet 28 and a rear side booklet 29, wherein, for example, the flap 23 is applied to the front side booklet 28. An overlap region 30 is thereby formed. Opposite this, a protruding region 31 is formed, along which the seam 16 runs for binding the flap 23 into the document 11. The front page booklet 28, which can also be referred to as a data page booklet, comprises at least one layer 32. Preferably, several layers are provided for forming the front side tack 28, such as a print layer which can be opaque, wherein a further layer is applied to the print layer, which is advantageously transparent.The back side stitching 29 can likewise comprise at least one layer 34 or have an analogous or different construction to the front side stitching 28. The front and / or back side stitching 28, 29 may include various security features, such as a Changeable Laser Image (CLI) feature or a Multiple Laser Image (MLI), as well as optically variable color (OVF) print images, or the like.The at least one layer 32 of the front side tack 28 and / or the at least one layer 34 of the rear side tack 29 can be produced from one or more plastics (polymers). In particular, these include polycarbonate (PC) or consist of PC. Further alternatives can be: bisphenol A polycarbonate, carboxy-modified PC, polyethylene terephthalate (PET), derivatives thereof such as glycol-modified PET (PETG), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polybutylene terephthalate (PBT), polyvinyl alcohol (PVA), polystyrene (PS), polyvinyl phenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS), and / or derivatives thereof, or from paper and / or cardboard or from mixtures of the aforementioned materials.The tab 23 is shown in an enlarged manner according to the detail X in FIG. 2 in a plan view in FIG. 5. According to this embodiment, the tab 23 is formed as a fabric 40. This fabric may comprise weft and warp yarns 43, 44 of plastic yarns. Alternatively, this woven fabric 40 can also contain textile threads and / or metallic threads and / or be produced from a composite of different threads.A thermoplastic material, in particular a polyester, for example polyethylene terephthalate (PET), is preferably used as the fabric-shaped strip material for the tab 23. The melting point or the glass transition temperature of the fusible material of the fabric-shaped tape material is preferably adapted to the material properties of the data carrier. The melting and / or glass transition temperature of the tab 23 and the melting and / or glass transition temperature of the data carrier 20 are matched to one another, so that when the tab 23 is connected to the data carrier 20, the fabric-shaped tape material of the tab 23 has not yet softened, but at least the layer 32, so that the fabric meshes are surrounded at least by the softened material of the layer 32.The schematic sectional view according to FIG. 4 shows that the tab 23 is applied on one side to the upper side of the layer 32, wherein in this exemplary embodiment the layer 32 comprises a receiving region 46. This receiving region 46 is formed by a reduction in the wall thickness of the layer 32. This in principle allows a virtually step-free binding of the tab 23 in the overlap region 30 to a surface of the layer 32 of the data carrier 20 adjoining it.In FIG. 6, an alternative embodiment for attaching the tab 23 to the data carrier 20 to form the data page 17 is shown. The receiving region 46 is not provided. Depending on the mesh width of the tab 23 and / or the pressure of a laminating tool or welding tool, the tab 23 is insert-molded into the tab 23 and / or the layer 32 in the overlap region 30 after the at least partial melting or melting of the tab 23 and / or the layer.FIG. 7 shows a schematically enlarged view of the sealing surface 39 on the tab 23, which is provided, for example, in an edge region of the tab 23. This sealing surface 39 consists of a plurality of welding points 48 which are arranged in a surface grid and are associated with one another. Preferably, the weld points 48 are aligned in rows and / or columns with respect to each other.In this exemplary embodiment, the warp and weft threads 43, 44 of the fabric 40 are aligned rotated by 45° with respect to the longitudinal side 41 of the data carrier 20. Consequently, the warp and weft threads 43, 44 cross the longitudinal side 41 of the data carrier 20 at an angle of 45°. The rows and / or columns of the welding points 48 are likewise aligned at an angle of 45° to the longitudinal side 41 of the data carrier 20. This arrangement has the advantage that the tearing out of individual threads is prevented. In addition, there may be an increased tear-out resistance compared to the seam 16.The size or the planar extent of the sealing surface 39 consisting of the mutually associated welding points 48 can take place over the entire protruding region 31 of the tab 23. Alternatively, it can be provided that one or more sealing surfaces 39 are provided, which are positioned in particular adjacent to one or two cut edges 49, wherein one or more sealing surfaces 39 can be aligned at a distance from one another along the cut edge 49. These sealing surfaces 39 can extend uniformly or else only singly over the width of the protruding region 31 or else only partially over the width of the protruding region 31.In FIG. 8, the fabric 40 is shown in an enlarged manner with warp and weft threads 43, 44 and an exemplary welding point 48. The warp and weft yarns 43, 44 include a stitch opening 45 formed by two adjacent warp yarns 43 and two adjacent weft yarns 44. As a result, crossing points 47 are formed by the threads 43, 44. The fabric 40 according to FIG. 8 shows a welding point 48 which is of diamond-shaped design. This welding point 48 comprises, for example, four mesh openings 45. The crossing points 47 outside the welding point 48, on the other hand, remain in the provided structure of the fabric 40. The size and / or shape of the respective welding point 48 can be selected as desired. The welding point 48 of FIG. 7 includes only one mesh opening 45. the welding point 48 of FIG. 8 includes four mesh openings 45. the welding points 48 may include one or more mesh openings 45. For example, square or rectangular welding points or round welding points or the like can also be formed.Between the individual welding points 48 only one row or one column of mesh openings 45 can be located. Also, multiple rows or columns of mesh openings 45 may be provided between two welding points 48.An alternative embodiment of the data page 17 to FIG. 7 is shown in FIG. 9. In this embodiment, the warp threads 43 or the weft threads 44 are oriented parallel to the longitudinal side 41 of the data carrier 20.The sealing surface 39 can be introduced by an ultrasonic connecting tool with an anvil and a sonotrode 50 according to FIG. 11, wherein the threads 43, 44 are at least partially melted and welded to one another by ultrasonic vibrations. As a result, the welding points 48 are formed.The formation of the welding points 48 is produced, for example, with a surface structure 52 of a sonotrode 50. This surface structure 52 of the sonotrode 50 has, for example, five elevations 51. An anvil 53 that is opposite a sonotrode 50 during an ultrasonic welding process can be designed analogously or planar. The size and / or the height and / or the geometric shape of the elevation 51 are preferably adapted to the size of the mesh opening 45. Pyramidal or truncated pyramid-shaped elevations 51 are preferably provided. In addition, the elevations 59 are preferably associated with one another in a diamond-shaped manner. For the introduction of the welding point 48, the elevations 51 are oriented rotated by 45° with respect to the stitch opening 45, so that the tip of an elevation 51 is not oriented with respect to the corners of the stitch opening 45 that are formed by the warp and weft threads 43, 44. The orientation of the elevation 51 is illustrated by way of example and in FIG. 11.The size of the surface structure 52 of the sonotrode 50 and of the anvil are preferably matched to the size of the sealing surface 39 to be achieved, so that the sealing surfaces 39 can be produced in one working step. Alternatively, it can also be provided that the sonotrode 50 and the anvil are positioned several times in succession with the tab 23 in order to create a sealing surface 39 of larger area. By the introduction of the individual welding points 48, the fabric 40 remains in the original state in the rows and columns lying between the welding points 48, that is to say that these regions are not heated. This allows the properties of the fabric 40, such as flexibility and / or crack resistance, to be maintained.The at least one sealing surface 39 is introduced by an ultrasonic process. This allows precise sealing, since the melting of the warp and weft threads 43, 44 can be controlled in a targeted manner depending on the material used. Moreover, energy-saving, environmentally friendly processing of the tab 23 with shortened process times is made possible. By structuring the sonotrodes and / or anvil surfaces by the elevations 51 which are adapted to the stitch opening 45, the shrinkage of the woven fabric 40 can be largely avoided and nevertheless a melting at the crossing points 47 of the warp and weft threads 43, 44 can be achieved. This also makes it possible to seal a cut edge 49 of the flap 23.Preferably, the at least one sealing surface 39 is introduced before the connection of the tab 23 to the data carrier 20. Alternatively, it can also be provided that after the connection of the tab 23 to the data carrier 20, at least one sealing surface is introduced. In the latter case, the sealing surface 39 can also extend into the overlap region 30.In FIG. 12, for example, a processing step during the production of the data page 17 is shown. In a first processing step, not shown in detail, a sheet having a plurality of data carriers 20 is cut, so that, for example, a strip of two adjacent data carriers 20 is provided. These data carriers 20 are provided in a blank size. Subsequently, the fabric 40 can be positioned as a strip-shaped material along a longitudinal side of the data carriers 20 in order to form the overlap region 30. The tab 23 is connected to an upper side of the data carrier 20 by lamination or welding. It is preferably provided that the uppermost layer of the data carrier 20 penetrates the mesh openings 45 of the fabric 40 and an additional interlocking effect is thus achieved. Subsequently, the sealing surface 39 can be introduced in the corner region of the tab 23. In a central region of the flap, i.e. between the two contiguous data carriers 20, the sealing surface 39 can furthermore be introduced, wherein a surface structure 52 is advantageously provided which is twice as long as the surface structure 52 for the corner region. Alternatively, only one surface structure 52 can be used, which acts twice and adjacent to one another on the tab 23 in order to form the middle locking surface 39.In a subsequent processing step, the data carrier 20 and the tab 23 are cut to a final dimension, as is shown by dashed lines by the reference numeral 55.The introduction of sealing surfaces 39 described above can take place before the attachment of the tab 23 to the data carrier 20. Alternatively, the introduction of the sealing surface 39 can also be provided after the laminating or welding of the tab to the data carrier.List of reference characters11 Book-like document 12 book cover 14 header 15 book block 16 seam 17 data page 18 inner side 19 image 20 data carrier 21 ICAO zone 22 personalization data 23 tab 24 transponder module 25 IC chip 26 antenna 28 front side stitching 29 rear side stitching 30 overlap region 31 protruding region 32 layer 34 layer 35 upper front edge of 26 36 lower front edge of 20 37 front side of 23 38 front side of 23 39 sealing surface 40 fabric 41 longitudinal side of 20 42 longitudinal side of 23 43 warp threads 44 weft threads 45 mesh opening 46.
