EP3339046B1 - Data carrier and method and device for manufacturing such a data carrier for a book-like document - Google Patents

Description

The invention relates to a data carrier as well as a method and a device for producing such a data carrier for a book-like document, in particular a value and / or security document.

Such security documents can in particular be passport documents, which are typically present in booklet or book form and in which an information storage medium is connected to the passport document. This data carrier is, for example, a passport book card or passport card that is integrated into the passport document. This passport book card contains personalized data and other data, for example information on the issuing authority. This passport book card must be connected to the other inside pages of the passport document in such a way that a third party cannot tear the passport book card out of the document in order to forge or falsify the passport document. In addition, it is necessary that by integrating this passport book card by means of a tab, an unlocking behavior of the passport document is improved so that after a single opening and subsequent closing the passport document also remains closed in order to prevent optical reading of the information.

From the DE 10 2012 112 383 A1 a method for producing such a data carrier for a book-like document is known. In this case, a flexible tape material to be attached to it is fed to the data carrier on one data side, so that an area of overlap with the data carrier is formed. The band material, which is provided by an endless band, is then cut off, so that after the flap has been positioned, forming an overlap area, it can be permanently connected to the data carrier.

In the production of such a data carrier, at least one outside of the data carrier is cut or punched by a cutting or punching tool produced. In this case, a burr is formed by such a trimming due to the cutting guide of the cutting tool on a lower end edge of the outside which is cut and opposite which the cutting tool exits downwards. During the further processing of the data carrier for incorporation into a book-like document, an adjacent page or a tab attached to the data carrier for incorporating the data carrier into the book-like document can be damaged.

From the EP 2 366 566 A1 a method for producing an insert sheet for a book-like document is known, in which a hinge foil is provided from the beginning as part of an insert sheet blank and the part of the insert sheet blank that is not required is removed by a machining process.

From the WO 2015/065217 A1 the production of a data carrier is known in which, after lamination, a cutting process is carried out with a cutting tool which comprises a first and a second cutting edge which produce a different depth of cut. In this way, a multi-tiered arrangement can be created from the data carrier to the tab.

From the DE 10 2010 054 480 A1 there is known a method for producing a insert sheet for a book-like document, in which a hinge element is inserted into a receptacle in the main body of the insert sheet. The insert sheet for receiving the hinge elements can be prepared accordingly by milling.

From the WO 2015/078542 A1 a method for producing a security element for documents of value and other data carriers is known in which at least two superimposed film webs are acted upon by laser radiation in order to completely cut through one film web in the predetermined dimensions of the security element.

The invention is based on the object of proposing a data carrier and a method and a device for producing such a data carrier which has a burr-free longitudinal edge.

This object is achieved by a data carrier defined in claim 1, in which a burr formed by a cutting process on the front edge of the outside is smoothed. This defuses the sharp, burr-prone front edge on the outside in order to avoid damage to neighboring sides. A connection of a tab can also be improved as a result, since a predetermined breaking point would be formed by applying a tab to a front edge with burrs.

Furthermore, the front edge of the outside is preferably thermally smoothed. Due to the thermal deformation of the front edge with burrs, a defined contour can be created in a simple manner.

The smoothed front edge is advantageously formed by a chamfer, a rounding or a step as a transition. This creates a haptically appealing outside of the data carrier.

A further advantageous embodiment of the data carrier provides that the smoothed end edge extends at least over a quarter of the width of the end face of the film composite. As a result, a smooth transition into a data page or the title page of the data carrier can be made possible from the front side along the outside.

The object on which the invention is based is further achieved by a method defined in claim 5 for producing a data carrier for a book-like document, in which the data carrier consists of a film composite with at least two layers, which is cut along at least one outside and a cutting guide with a Cutting tool for forming the outside of a title page to the data page of the data carrier or from a data page to the title page of the data carrier and on the data page or title page from which the cutting tool emerges, a ridge protruding from the data page or title page is formed along one end edge of the outside and in which the burr formed on the front edge of the outside is smoothed. This removes the burr in a simple manner. In addition, the smoothing can be used to create a desired edge contour at the same time.

The burr provided on the front edge of the outside is preferably thermally smoothed. This allows easy editing of the Front edge without further post-processing. The thermal smoothing can melt the burr and flow back into the adjacent layer, so that a burr-free surface is formed.

Furthermore, the front edge of the outside is preferably placed on a thermally heated smoothing device and held on the smoothing device under pressure and smoothed. This enables the front edge of the outside to be smoothed quickly and easily, without the need for further rework or waste material. The data carrier is aligned with the burr-prone front edge on the outside - preferably parallel to the smoothing device - and positioned on the smoothing device over the entire length of the front edge. Uniform contouring or smoothing can thus take place over the entire length of the outside of the data carrier.

The data carrier is advantageously aligned at an angle to the smoothing device designed as a heating plate and placed on it. Depending on the angular position of the data carrier in relation to the heating plate, a smooth surface can be formed on the outside. A longitudinal center plane of the data carrier is preferably oriented at an angle between 1 and 89 °, preferably 30 to 60 °, inclined to a support surface of the heating plate.

A bevel is preferably formed on the outside of the data carrier. This can be aligned, for example, at an angle of 45 ° to the data page or title page. Further angular ranges can also be provided. Alternatively, the front edge of the data carrier with burrs can also be designed as a rounding or stepping. In this way, a particularly appealing feel can be created. It is preferably provided that the bevel or the transition takes up at least a quarter of the width of the outside.

Another preferred embodiment of the method provides that the smoothing device is set to a temperature above a glass transition temperature of at least one of the layers of the film composite, preferably to a temperature range between 200 and 350 ° C and the outside of the data carrier is placed on the smoothing device with a force of 5 to 25 Newtons and a duration of 1 to 5 seconds. This enables the burr-affected front edge of the outside to be melted and a desired contour to be introduced.

The object on which the invention is based is furthermore achieved by a smoothing device for producing a data carrier as defined in claim 14, according to a method according to one of the embodiments described above, which has at least one heating plate with a support surface and comprises at least one length of an outer side of the data carrier. As a result, when the data carrier is placed on the smoothing device once along the entire outside of the film composite, the burr-affected front edge can be smoothed sufficiently.

The support surface of the heating plate is advantageously designed to be flat or has a rounded or V-shaped recess. A smoothing contour of the front edge along the outside can be determined and introduced through the shape and contour of the support surface. In the case of a flat support surface, a bevel is formed between an end face and an adjoining data or title page of the data carrier. With a rounded recess, a curved contour can be created. In the case of a flat V-shaped recess, a type of double bevel can be formed.

In Figure 1 a book-like document 11 is shown. This book-like document 11 is, for example, a value and / or security document, in particular a passport. This document 11 comprises a book cover 12 with a book cover front side 13 and a book cover back 14 an attachment 18 can be applied. The book cover binding 17 and the attachment 18 are preferably connected to the at least one book cover insert by gluing.

The book cover 12 accommodates several inner pages 19. A data carrier 21, such as, for example, a personalization data page, is also preferably provided. The inside 19 and / or the data carrier 21 and the attachment 18 are preferably connected to one another to form a book block 22 and fastened in the book cover 12. For example, the inner pages 19 and / or the data carrier 21 and the header 18 can be connected to one another by a seam to form a book block 22.

The data carrier 21 designed as a personalization data page is designed, for example, in accordance with the ICAO standard and comprises an image 24 of the document owner, an OCR (Optical Character Recognition) machine-readable line 25 and further personalization data 26.

According to this exemplary embodiment, the data carrier 21 can furthermore comprise a transponder module 28 in which the data of the document owner and further security features can be stored. The data carrier 21 is designed, for example, as an insert sheet and, according to the exemplary embodiment, may include a tab 29 that extends beyond a seam region 30. Alternatively, instead of the tab 29, a complete personalization or data page can be provided.

The data carrier 21 comprises at least two plastic layers which are laminated with one another and form a film composite. The transponder module 28 is provided in between. A further layer, in particular made of paper, which comprises the personalization data 26 as well as the image 24 and the OCR machine-readable lines 25, can preferably be introduced between the at least two outer plastic layers. The outer plastic layers are preferably made of polycarbonate and preferably completely enclose the inner layer.

The transponder module 28 comprises an IC chip 32 and an antenna 31 connected to it, which consists of several windings and can preferably be printed on.

In Figure 2 a plan view of the data carrier 21 is shown. The data carrier 21 comprises a tab 29, for example made of a flexible strip material. This flexible band material can be, for example, a fabric made from a textile band material. For example, the DE 10 2012 213 913 A1 Referenced. Such a textile band material can preferably be connected to an outermost layer or layer of the data carrier 21 by welding. The tab 29 has an area 36 protruding beyond an outer side 35 of the data carrier 21. The connection of the data carrier 21 to the inner pages 19 for a book block 22 takes place within this protruding area 36. The seam 30 can also be introduced in this protruding area 36. The tab 29 is connected to the data carrier 21 in an overlap area 37.

In Figure 3 FIG. 11 is a schematic side view of the data carrier 21 according to FIG Figure 2 shown. The data carrier 21 comprises a title page 38 or a rear side and a data page 39 or respectively a front. Data page 39 is also in Figure 1 on which the personalization data can be seen.

The data carrier 21 receives the tab 29 on the title page 38, for example. After the tab 29 has been welded to the data carrier 21, this tab 29 can be provided with an outside flush with the title page 38. The longitudinal edge 35 comprises an end face 41 which is assigned to the tab 29.

The data carrier 21 consists of two or more layers made of one or more materials made of plastic, which form a film composite or laminate composite.

Furthermore, the data carrier 21 is preferably formed from one or more layers and the one or more layers from one or more plastic materials are used to form a data carrier 21 or a data carrier 21 in the laminate composite. In this way, in particular, a good connection of the textile tape material for formation on the data carrier 21 can be made possible. For example, welding can take place, whereby at least a clawing of the textile tape material with the data carrier is made possible. The data carrier is preferably formed from a polycarbonate or from a polycarbonate derivative. To form the data carrier, plastics can be provided, in particular bisphenol A polycarbonate, carboxy-modified PC, polyethylene terephthalate (PET), its derivatives, such as glycol-modified PET (PETG), carboxy-modified PET, polyethylene naphthalate (PEN), polyvinyl chloride (PVC) , Polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS), polvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomer (TPE), especially thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and / or their derivatives or made from paper and / or cardboard or from mixtures of the aforementioned materials. The material for the data carrier is preferably formed at least partially from polycarbonate or from a polycarbonate derivative.

To produce the data carrier 21 with the tab 29 arranged thereon, after the layers have been laminated to form a film composite, at least the outside 35 is cut or punched with a cutting tool. With such a trim, the outer side 35 can have an end face 41 which is delimited by two end edges 42, 43 which differ from one another.

In Figure 4a an outside 35 of the data carrier 21 after the trimming is shown schematically enlarged by way of example. The upper end edge 42, on which the cutting tool is initially fed, is free of burrs and can be rounded. The opposite end edge 43, at which the cutting tool emerges downward relative to the data carrier 21, has a ridge 44. Usually, a cutting guide is provided on the data carriers 21, in which the cutting tool is guided from the title page 38 to the data page 39. This can also be interchanged. The cutting guide of the cutting tool is preferably oriented perpendicular to the longitudinal center plane 46. A cut is also possible which is oriented at an incline to the longitudinal center axis 46.

When a tab 29 is connected to the data carrier 21, after the data carrier 21 has been bound into the book-like document 11, the ridge 44 points in the direction of the adjacent inside 19. This can lead to damage. It is therefore provided that the end edge 43 is smoothed in order to remove the burr 44. For this purpose, the data carrier 21 is aligned inclined with respect to its longitudinal center plane 46 to a support surface 48 of a smoothing device 51. The smoothing device 51 is preferably designed as a heating plate with the support surface 48. This heating plate is preferably heated electrically, in particular by heating cartridges.

The data carrier 21 or the longitudinal center axis 46 of the data carrier 21 is aligned inclined with respect to the support surface 48 of the smoothing device 51, for example at an angle between 1 and 89 °, preferably in a range between 30 and 60 ° and in this orientation according to arrow 53 on the heating plate fed and held down according to a predetermined period of time and a predetermined force to this. A front edge 43 with the ridge 44 on the Support surface 48 are placed and then the alignment of the longitudinal center axis 46 of the data carrier 21 with the support surface 48 takes place. After putting on the front edge 43 is melted and smoothed, as in Figure 4b is shown. A bevel 55 is formed by this smoothing. The alignment of the bevel 55 or the angular position of the bevel 55 with respect to the end face 41 is determined as a function of the inclined positioning of the data carrier 21 with respect to the heating plate 51. The heating plate is heated to at least a temperature above the glass transition temperature of the at least one layer of the data carrier 21. The heating temperature is preferably far above the glass transition temperature of the plastic of the film composite to be melted on. For example, a temperature range of 200 to 350 ° C. is provided in order to achieve rapid melting. With a contact pressure of 15 Newtons, for example, a period of 1 to 2 seconds can be sufficient to apply the bevel 55. The data carrier 21 is then lifted off, as shown in FIG Figure 4c is shown because the front edge 43 is smoothed.

The tab 29 can then be attached to the data carrier 21, this being applied to the title page 38 and adjoining the front edge 42 which is opposite the smoothed front edge 43.

In the Figures 5a to 5c are process steps analogous to the Figures 4a to 4c shown. This alternative embodiment of the method only differs in that instead of a flat support surface 48 of the smoothing device 51, a support surface 48 with a recess 57 is provided. This recess 57 is preferably designed as a rounding. As a result, a rounded transition 58 can be created on the front edge 43 instead of a bevel 55.

In the Figures 6a to 6c is another alternative embodiment of the method to the Figures 5a to 5c shown. The support surface 48 of the smoothing device 51 again has a recess 57, which, however, differs from the recess 57 formed as a rounding according to FIG Figure 5c as a recess 57 with a flat V-shaped contour according to FIG Figure 6c is trained. This allows a stepped transition 59 on the front edge 43 be formed. This recess 57 can also be composed of several individual surfaces in order to form the stepped transition 59.
