Description

DESCRIPTION

Procedure for attaching at least one connecting tab to a document sheet, procedure for manufacturing a security document, as well as a security document

The present invention relates to a method for manufacturing a security document, to a method for attaching at least one connecting tab to a document sheet, which can be attached to the security document, as well as to a security document. The security document can be for example a passport, identity card, driving license, access control card, a vehicle registration document, registration document, visa or other identity document, a checkbook, a voucher gift or purchase, a bill of lading or other credential or other identity document. The document is preferably a passport or identity card.

This type of security documents can be in particular passport documents, which are typically presented in book or book form and in which a document sheet that stores information is attached to the document. The document sheet is for example a passport book card, which is integrated into a passport document. Personalization data and other data, for example information on the place of issue, are contained in the passport book card. The passport book card must be linked in such a way with the other pages of the passport document that a third party cannot separate the card from the document, so that falsification or alteration of the document can be avoided. In the event that this type of falsification or alteration is still carried out in the document, they must be easily recognizable.

A booklet with a personalized data sheet is described for example in EP 1502765 A1. This booklet has several sheets between an envelope. The data sheet is securely attached to the booklet wrapper. It has a flexible layer, which protrudes with an area of the data sheet. The data sheet is connected in this area with the envelope and the remaining sheets.

Document EP 1878589 A1 describes a procedure for the manufacture of an information sheet and an information sheet respectively for a security document. In an information part there is provided a flexible and kink-resistant fixing section. The fixing section comprises a support layer configured for example as a sheet and a net-like structure.

EP 2 479 038 describes a security document and a procedure for its manufacture. A multi-layer joining element, the contact layer of which is thermally attached to a data page is of the same material as the data page.

A similar object is shown in document WO2007 / 114700 A1, in which a fiber reinforced hinge section is attached to a so-called holder page strip of a plastic material.

Also document WO 2007/054618 A1 shows an information sheet, to which a flexible fixing section is attached. This preferably consists of a network.

In document DE 10 2008 031 654 A1 a document card is also disclosed, which can be integrated into a security document configured as a book. The data card is incorporated using these two tab strips in the security document. For this purpose, through holes are inserted into the edge body along one edge of the card body. The card body is then disposed between the two tab strips, so that the through holes are respectively covered on both sides of the card body. The tab strips are joined by introducing ultrasound energy at the points of the through holes with the card body, as linkages are established between the two tab strips through the through holes. As a result, the tongue strips are attached in a positive connection with the card body. The document card produced in such a way is then incorporated through the tab strips in the security document configured as a book.

With the known procedure it is possible to incorporate a data card in a security document in the form of a book or a book. However, the known manufacturing procedures do not yet meet the required requirements: on the one hand, the process must be able to be carried out in a simple way in order to be able to manufacture the security document in an economical and high-performance way. In addition, it has been found that the documents in the form of a book or book produced in this way are easily closed, that is, they are kept without the influence of an external force in an approximately half-open state and can only be opened completely in the event of the application of an external force. It is advantageous, however, when the document is also held without the application of a force acting from the outside in the closed or fully open state. Naturally, it is also required that the security document be for the most part secure against counterfeiting and alteration.

As long as the terms "document" and "security document" are used in this description and in the claims, a passport, identity card, driving license, access control card, a document, a document is to be understood in particular. vehicle registration, registration document, visa or other document identity, a checkbook, a gift or purchase voucher, a freight bill or other credential or other identity document. The (security) document is preferably a passport or identity card. Very particularly preferably the (security) document is configured in the form of a book or a book, that is, it comprises several pages, which can be turned. The document sheet may in particular form a card of a (security) document. In case the (security) document is a passport, a document sheet contained within it is preferably a passport book card. The (security) document is formed from a document body and a document sheet, which are joined through at least one connecting tab. The body of the document can be presented in the form of a book or a book, that is, it can have several pages, which can be turned. The security document can for example be a passport, which has several visa sheets.

As long as the concepts "document sheet" and "sheet" are used in this description and in the claims, they should be understood as flat supports, preferably rectangular, for information to be displayed. These supports can be thin and thus flexible as a sheet of paper or a sheet of thin plastic material or thicker than a sheet of paper or a sheet of plastic material and thus less flexible than this, for example as a piece of cardboard or as a card, which may well be twisted, but can no longer be rolled up. In addition to this, rigid plates are to be understood, which can practically not bend and twist. In this way the (document) sheet can also be configured in the form of a card. In case the document is a passport, the document sheet is preferably a passport book card. The format of the document (document) is guided according to the document, in which it has to be integrated. It may for example have one of the formats ID 1, ID 2 or ID 3 in accordance with ISO / IEC 7810. The document (security) specification may also be made from a material suitable for the purpose in accordance with the invention, for example from a plastic (polymer) material, from paper, cardboard, glass or other materials or mixtures of these materials, and possibly filled with reinforcing materials. The thickness of the document sheet is preferably 250 to 950 pm.

The method according to the invention relates to the attachment of at least one attachment tab formed from a textile material with a sheet of information storage document according to the accompanying claims 1 to 7.

By means of the at least one connecting tab, the document sheet can be connected to the document body of a security document. The textile material of the at least one connecting tab is different according to the invention from the sheet material that forms the document sheet. The sheet may be configured in particular to be able to be incorporated by means of the at least one connecting tab in a book or book, which consists of sheets, sheets and, if necessary, book or book covers and / or book or book spines, or be able to be bound together with other sheets, plates and, if necessary, book or book covers and / or book or book spines, giving rise to a book or book. The method according to the invention preferably comprises, in the order indicated below, the following procedural steps: a) overlapping arrangement of the at least one connecting tab and the document sheet, such that an overlapping area of the at least one connecting tab is formed with the sheet, b) welding the at least one connecting tab and the document sheet in the overlap area.

The present invention further relates to a method of making a security document, in accordance with the accompanying claims 8-11.

This procedure comprises the following procedural steps: A) making available the document sheet that stores the information and the at least one connecting tab formed from a textile material, the textile material of the at least one connecting tab. different from the sheet material that forms the document sheet; B) overlapping the at least one connecting tab and the document sheet, so that an area of overlap of the at least one connecting tab with the document sheet is formed, C) welding the at least one tab of union and the document sheet by the overlapping area; and D) fixing the document sheet to the document body of the security body through the at least one connecting tab.

The present invention furthermore relates to a security document in the form of a book or book, according to the accompanying claim 12, which has a body of document presenting one or more pages of book or book, as well as at least one connecting tab, which is attached to the document body, as well as a document sheet that stores information. The document sheet is connected to the at least one connecting tab by means of a welded connection, the at least one connecting tab being formed from a textile material and the textile material of the at least one connecting tab being different from the material sheet that forms the document sheet.

The present invention is based on the idea that a connection of a document sheet to the document body of a security document by means of a connecting tab is advantageous because in this way a flexible connection of the document sheet to the document sheet and document can be easily closed without the application of external force or held open. It has been surprising however, that a fixed connection, in particular a connection of materials (i.e. a connection of materials of materials to each other) between the Document sheet and tie tab can also be achieved when the sheet material and tie tab material are not identical, since a secure material bond was expected only in case of welding of identical materials to each other.

By configuring the connecting tab as a textile material, it is further ensured that the security document, in which the document sheet is integrated by means of the connecting tab, can be easily handled, since the document can be closed and open without further problem without closing in this regard and without returning to a half-closed state. Since the textile union tongue has the necessary flexibility for this. Also by means of the closing process, the joint tongue is not reduced in its flexibility, since the weld does not extend to the flexible area. Furthermore, it is achieved by the welding process to join the binding tab with the document sheet, a bonding joint of materials between the binding tab and the document sheet, which guarantees that the document sheet can no longer be removed without destruction of the security document when it is detached from the connecting tab. For this, the material of the connecting tab is joined with the material of the document sheet through at least one connecting point directly. It has also been seen that the possibility of using different materials for the document sheet and the connecting tab enables optimization also with regard to the most suitable materials for the selection of the appropriate components. Since it has been verified that there is no limitation to certain materials in terms of good weldability. With the secure union of materials, a forgery or alteration of the security document is practically ruled out, at least with regard to the aforementioned replacement of the document specification. This joint can be easily manufactured and is thus due to a reduced number of process steps required therefor economically and essentially non-fault prone. By welding, a pattern present in the overlap region of the document sheet, for example a print image in the form of alphanumeric signs, is visible through the textile tab. This may represent a security feature for the document specification. During welding, it is true that the textile properties are lost in the joint area. In the hinge area, that is, outside the connection area, they are nevertheless maintained.

The textile material of the connecting tongue can be configured in any way. It may for example be formed of a textile sheet material in the form of a fabric, a knitted fabric, a woven fabric or the like, or in the form of a felt or non-woven fabric, provided that it has the required resistance to breakage. The material is preferably formed from a union of filaments, in particular fibers, yarn, threads or the like, which in the case of a fabric, knitted fabric, woven fabric or the like are arranged in an orderly manner with each other, while the filaments of a felt or non-woven fabric, for example fibers, are arranged in an unordered manner. The textile material is preferably formed of a knitted fabric, in particular with warp and weft threads.

The textile material of the connecting tongue may consist in particular of one or more materials that can be melted or comprise them, to enable the welding process. The at least one meltable textile material is preferably formed from a plastic (polymer) material, more preferably still a thermoplastic plastic material. The use as a thermoplastic plastic material of a polyester, for example polyethylene terephthalate (PET), or a thermoplastic polyurethane (TPU), has proved to be particularly advantageous, since these materials can be spun without problems giving rise to threads or the like and can continue being processed then to give rise to the textile material. The textile material may preferably be formed at least partially of polyethylene. The melting point or the glass transition temperature of the meltable material should preferably be adapted to the properties of the document sheet material. The melting or glass transition temperatures of the connecting lug and the document sheet are preferably of the same magnitude (for example within a temperature range of 50 ° C), so that the welding process can be carried out without error and easily. Furthermore, the textile material may consist partially of cotton, that is, contain it. It may for example consist of a cotton-polymer blend, in particular a cotton-polyester blend.

In another preferred embodiment variant of the present invention, the textile material of the at least one connecting tongue is formed from two different materials (mixed fabric), of which one during welding with the document sheet at least melts and the other material during the welding process does not bond with the document sheet, that is, it does not melt, so that no weld joint of this other material is formed with the document sheet. The warp yarns of a mixed fabric can for example be kept unchanged during welding, while the weft yarns start to melt or melt and are fixedly attached to the document sheet material. The warp threads in this case extend from the free edge (not in the overlap zone) of the connecting tongue to the overlap zone. Because they do not start to melt or melt, the strength of the material of the connecting tongue is maintained in the area of passage between the free edge and the area of overlap.

The materials of the at least one connecting tongue can have, in accordance with the last-mentioned embodiment variant, in a first preferred embodiment, different melting points or glass transition temperatures. A first material may for example have a first melting point or a first glass transition temperature, so that it begins to melt or melts under the conditions of the welding process, and a second material may have a second melting point or a second temperature. glass transition which / which is notably higher, so that the second material in the same conditions of Solder does not start to melt or melt.

In a second preferred embodiment of the last-mentioned variant embodiment, the textile material may be formed from at least two materials, of which a first material has a melting point or a glass transition temperature, so that under the conditions of the welding process it begins to melt or melts, and of which a second material is not a material that can be melted (in particular no thermoplastic plastic material), but for example another material other than plastic material, such as a cellulose material or a protein, for example a wool material, or a hard plastic or carbon material, fiberglass, inorganic or metallic fibers (wires), so that this second material during the welding process does not begin to melt or it's melting.

In the two cases mentioned above, the second material does not melt during the welding process and is thus maintained in an unmodified form, so that the internal resistance of the at least one connecting tab is not negatively influenced by the process of welding.

Preferably only a single tie tab is used to join the document sheet to the document body of the security document. In principle, several connecting tabs can of course also be used for this connection, for example by the superimposition of several of these connecting tabs. In the following, reference is made in a simplified manner and in representation of the corresponding embodiments to a connecting tab.

unión sobresale lateralmente del pliego de documento. Esta zona de unión sirve para la unión posterior de la unidad de lengüeta de unión y pliego de documento unido con ella con el cuerpo de documento del documento de seguridad. La zona de unión puede estar configurada en particular en forma de tira. Este borde libre presenta una superficie de unión alargada, la cual se encuentra a disposición para la unión con el cuerpo de documento. La lengüeta de unión puede presentar al menos una característica de seguridad, por ejemplo uno o varios hilos de seguridad.The connecting tongue is preferably an elongated sheet material, in particular rectangular, which is wide enough to be able to overlap on the one hand on the edge side with the document sheet, so that a fixed weld joint can be generated, and to be able on the other hand to form an area of union with the security document. The tear tab is preferably in an extension direction just as long as the document sheet, so that the tether tab extends over a full edge length of the document sheet and not beyond. The joining tab overlaps the document sheet by one overlapping area, so that another joining area of the tab d

joint protrudes laterally from the document sheet. This connection area serves for the subsequent connection of the connection tab and document sheet unit connected with it to the document body of the security document. The connection area can be configured in particular in the form of a strip. This free edge has an elongated bonding surface, which is available for bonding with the document body. The connecting tab can have at least one security feature, for example one or more security threads.

The document sheet can be made from one or more materials. The document sheet is preferably presented in the form of a laminated material, which is made from several layers of laminated material by lamination. The document sheet can however also be manufactured basically by injection molding or extrusion or other manufacturing process. The document sheet is preferably made from one or more plastic materials (polymers), in particular polycarbonate (PC), most particularly bisphenol A polycarbonate, carboxyl-modified PC, polyethylene terephthalate (PET), its derivatives such as glycol modified PET (PETG), carboxyl modified PET, polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethylmethacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA) ), polystyrene (PS), polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS), and / or its derivatives, or from paper and / or cardboard or from mixtures of the previously mentioned materials. It is preferred that the sheet material is at least partially made of polycarbonate or a polycarbonate derivative. The document sheet is preferably a laminated material, which is formed from several layers. One or individual layers of the laminate material may consist of PC or PC / TPU / PC or contain these materials. Other layers may consist entirely of or contain the same material or different materials. The polymers can be filled or unfilled. In the latter case, the layers are transparent or translucent. If the polymers are filled, they are typically opaque. The filler material can therefore be for example a pigment. The layers can be tinted or colorless. The outer layers of the document sheet (top layer sheets) can be particularly colorless, transparent and have high abrasion resistance. The laminated material is preferably formed from a thermoplastic material, which during the welding process begins to melt or at least partially melts in the at least one joint area.

In a preferred embodiment of the present invention, welding is carried out by a method that introduces sound waves into the overlap zone. The welding procedure may in particular be an ultrasonic welding process. For this, a sonotrode is used, which can be oscillated by ultrasound. For the welding process, the sonotrode is placed on the joint area of the joint parts to be welded (joint tab or document sheet), so that the energy contained in the ultrasound oscillations is introduced into the joint area in the materials of the connecting parts. Due to this, the materials to be joined are heated, so that at least one material of the connecting parts melts and the connection takes place. Basically other binding mechanisms are also conceivable, for example a close bonding of the materials to each other, so that (chemical) atom bonds can occur. During the welding process the sonotrode can be pressed by acting a clamping pressure on the joint point, to be able to introduce the pressure in the most efficient way possible in the union area. For this, a counter-bearing (machine table, anvil) may have been arranged in front of the sonotrode, on which the connecting parts that are one above the other and are pressed by means of the sonotrode are arranged. Ultrasound is preferably generated in the sonotrode using a piezoelectric crystal, from which the mechanical oscillations generated in it are transmitted to the sonotrode's work surface.

In one variant embodiment, the sonotrode can have a flat working surface, so that the connecting tab is welded over the entire area of the working surface of the sonotrode with the document sheet. The working surface of the sonotrode can be basically as large as the overlap area of the connecting tab with the document sheet. The working surface of the sonotrode may alternatively also be smaller (alternatively also larger) than the overlap zone. In case the working surface is smaller than the overlap area, a weld point is generated, which is smaller than the surface area.

The connecting tab and the document sheet are welded together in the overlap area in at least two separate welding areas. For this purpose, the work surface of the sonotrode is configured according to the invention with a profiling with protruding partial zones, through which energy is introduced only in the welding zones at the point of attachment, since only these partial zones are in direct contact with the junction point. This ensures that the entire overlap area of the connecting tab with the document sheet is not used for the connection. In particular when the bonding tab textile material is formed exclusively from meltable material, the strength of the bonding tab is not adversely influenced in this way during welding, since the material only melts in zones, while that areas that are between them do not begin to merge, at least however they do not merge. This prevents the filament structure in the passage between the free edge of the connecting lug and the overlap area from being completely destroyed during the welding process, so that the strength of the material and its flexibility in the area hinge are held to their fullest extent. The weld zones separated from each other are preferably arranged as a grid. Even more preferably, the grid measurement corresponds to the separation of adjacent threads, fibers or meshes. In this way the structure of the work surface of the sonotrode can be configured in relation to the type of tissue.

In a preferred embodiment of this improvement, the at least two welding zones separated from each other have longitudinal extension and are arranged parallel to each other. The welding areas can basically be arranged in another preferred embodiment variant of this improvement also in the form of a point and for example in a regular grid pattern. In the two variants of embodiment mentioned, the raised partial zones of the sonotrode have a corresponding shape to form the mentioned shapes of the welding points. In another preferred embodiment variant of this improvement, the weld zones separated from each other can also be configured in the form of information storage characters, for example, alphanumeric characters or symbols or the like, for example letters, images or in the form of micro-writing. The solder joints between the connecting tab and the document sheet are formed in this case in the form of these characters. This embodiment variant thus represents a security feature, which cannot be reproduced without further ado. Since the tie tab textile material when using transparent materials during welding becomes transparent, the weld areas can be made highly visible by using a tinted sheet material. Alternatively, a joint weld zone may also be produced with a correspondingly shaped work surface of the sonotrode, which is configured in the form of a pattern of raised partial zone structures on the work surface of the sonotrode, for example in the form of patterns in the form of rhombus or the like. The raised partial zones on the sonotrode are flattened according to the invention or may also be configured not according to the invention so that they end in a pointed position.

The sonotrode is preferably arranged on the side on the stack starting from the connecting tab and the document sheet, preferably under pressure, by which the connecting tab is located, that is, it is found during the welding process in direct contact with the connecting tab. Basically, it is also conceivable to introduce energy into the connecting parts from the side of the document sheet. The former is preferred, since the textile material is compacted by direct contact with the sonotrode, so that close contact of the connecting parts results. The bonding time depends on the input power and the type of material to be welded. The binding time is typically 0.1 to 2 s, preferably 0.2 to 0.4 s.

The unit from the document sheet and the connecting tab, which are fixedly connected to each other, can be connected to the document body of the security document. When the security document is presented in the form of a notebook or book, it presents a spine of a notebook or book. This also includes the fold area of a notebook. The unit from the document sheet and the connecting tab is joined according to procedure step D of the procedure for manufacturing the security document through the connecting tab, preferably in the area of the book or book spine with the document body. For example, the free edge of the connecting tongue can be connected by gluing, sewing or welding with the document body.

The method according to the invention for manufacturing the security document, comprising the steps of procedure A, B and C, according to which the unit is manufactured from a joint tab and document sheet joined together, further includes procedure step D, according to which the joint tab is joins with the document body. This process step can be carried out after the production of the connection between the connection tab and the document sheet, that is, after the document sheet has been completed, in particular individualized, for example personalized, and has been attached with the tie tab. For this purpose, the document sheets produced for the corresponding purpose of use are attached at any place (and not only at the place where the document sheets are manufactured) with the document body. The following procedure development results in the indicated order:

The attachment of the attachment tab to the document body can alternatively also be established already prior to its attachment to the document sheet, that is, between procedure steps A and B, so that the attachment of the document sheet to the Binding tab occurs after binding in the document body. The following procedure development results in the indicated order:

In the event that according to one of the preferred variants described above, a weld joint is established, for example in the form of a security feature, between the joint tab and the document sheet, the first method of procedure is advantageous, since the union of the union tab with the document sheet and the incorporation of this unit in the document body can take place in different places, the incorporation of the unit in the document body should not take place in this case necessarily in an environment of particular security. Since the manufacturing steps required for the manufacturing of the security features (manufacturing of the document sheet and bonding of the tab to the document sheet) are carried out successively by incorporation of procedure step B, while that the next step of embedding the unit in the document body (step D) can occur separately from it. This allows for more flexible logistics than when procedure step D is carried out between steps A and B. On the other hand, document bodies can be kept in storage by incorporating the connecting tab in the document body (procedure step D). between steps A and C, in particular when the connecting tab is integrated between other pages of the document body or between other pages and the book cover of the document body, as in a passport.

The connecting tab (if necessary together with the document sheet) can be incorporated in a document body in the form of a book or a booklet, so that the sheet forms an inner page of the security document. The body of the document has other pages in this case, as well as, in the case of a book or notebook spine. The connecting tab can optionally be incorporated in the body of the document not yet finished, since together with the connecting tab also pages and, if necessary, the book or book spine are joined together.

In an embodiment of the present invention, the connecting tab is located on the inside of the book or book, preferably in the area of its fold. The document sheet can be attached via the binding tab also as an outer page (instead of a book cover, notebook). In this case, the connecting tab can form the spine of the book or notebook (gluing tape). The document sheet can be provided in this embodiment with security features, in particular with data, preferably personalization data. The security features, in particular data and very particularly personalization data, are preferably arranged on the side of the document sheet, which is directed towards the inside of the book, that is, not on the outside of the document. book or notebook. In this embodiment, not only the document sheet can be connected to the connecting tab by means of ultrasound, but also another outer side.

In production the connecting tabs and document sheets can respectively be joined and welded together. Alternatively they can also be processed in a roll-to-roll installation. For this purpose, the corresponding roll materials are available for the connecting tab and the document sheet, which are suitably joined (they are made available and arranged on top of each other in a coincident manner) and then welded together. After that, the materials of the connecting tab and the document sheet are welded together through the overlap area. These units are finally separated from the roll materials.

The document sheet is typically used to identify a person or thing. Because of this, it is preferably configured as an individualized document, in particular personalized. For this, the document sheet presents security features, such as a photo of the person, data related to this person or thing in clear writing or in encoded form or through an appropriately shaped form, which can hardly or only be reproduced with difficulty, such as data reproduced with special luminescent colors for example alphanumeric representation, or slanted images, holograms, special printing patterns such as guilloche, variable colors and the like. The document specification can also be configured as an RFID ( radio frequency Identification ) document with an antenna and an RFID semiconductor chip. The document sheet may furthermore also present electronic components, such as electronic displays, sensors, such as contact sensors, and the like.

The present invention is explained in greater detail by the figures described below. These figures, as well as the description of the figures, represent only an exemplary description of the present invention, without limiting the scope of protection of the present application.

The security document 1 represented in Fig. 1 is for example a passport. This is formed from a cover (spine) of the book 2 on the outer side, for example cardboard, several sheets of passport 3a, 3b, 3c, ... and the document sheet 4, in the present case a business card passport book from a laminated PC material. The book cover 2 may have a hinge 5, in the area of which parts of the book cover 2 come into contact with each other. The book cover 2 may for example consist of two rigid parts 2a, 2b adjacent to each other, which are linked together through flexible wrapping, as the wrapping wraps the parts. The book cover 2 may be provided on the outside with an emblem, for example in the issuing state.

On the inside there are attached several document sheets 3a, 3b, 3c, ... for the accommodation of visible indications and the passport book card 4 with the book cover 2. The book cover 2 and the document pages 3a, 3b, 3c, ... form a document body 20.

The passport book card 4 is connected via a connecting tab 6 with the document pages 3a, 3b, 3c, ... and the book cover 2. For this purpose, the passport book card 4 is attached by manner according to the invention through a soldered joint 7 with the connecting tab 6. The passport book card 4 is arranged between the book cover 2 and an inner document page 3a. For joining these components are sewn together. The seam 8 (a thread) passes through the document pages 3a, 3b, 3 c,., The connecting tab 6 and the book cover 2 in the hinge area 5 and joins them together. To anchor seam 8 on the spine of book 2, a gluing tape 9 of a flexible material is attached to the hinge 8.

Document pages 3a, 3b, 3c, ... represent the visa pages of passport 1. They are not, except for a guilloche security print, watermarks and possibly an identification number, provided of other security features or other printing features.

The passport book card 4 has various security features and particularly personalizes passport holders. For this, a photo of the owner, his personal data in clear writing, as well as other security features are contained. The passport book card 4 can also be equipped as an RFID document with an antenna and an RFlD semiconductor chip, and optionally equipped with electronic components.

The connecting tab 6 is made from a thermoplastic PET woven material. Because of this it is flexible, so that the passport 1 can be closed and opened without problems. PET has a melting point or a glass transition temperature, which allows a soldered joint to be established with the passport book card 4, as the material of the joint tab 6 begins to melt or even melt. In addition to this the passport book card 4 is also made from a meltable material, namely in the form of a PC laminate material, which has thermoplastic properties. This material also begins to melt or even melts when energy is introduced. The welded joint 7 formed is extremely strong. Fig. 2 shows a security document 1 in the form of a passport in an alternative embodiment. This embodiment differs from that shown in Fig. 1 in that one half of the book cover 2 (preferably the front side of the passport 1) of the passport 1 is in this case formed by the passport book card 4 The passport book card is preferably provided on the inward side (towards document pages 3a, 3b, 3 c,.) Of the data. The other half of the book cover 2 (preferably the back side of the passport 1) is configured as in the embodiment of Fig. 1 as part 2a. In place of the gluing tape 9 shown in Fig. 1, there is in this case the connecting tab 6. The part 2a of the book cover 2 is like the passport card 4 joined through a joint welded 7 with connecting tab 6.

In Fig. 3 a unit is schematically represented in top view from a connecting tab 6 with the passport book card 4. The overlapping area 21 between the connecting tab 6 and the passport book card 4 extends for the entire edge length of the passport book card 4, since the connecting tab 6 is as long as the edge length.

The representation shown in Fig. 4 of an ultrasonic welding device 10 shows a sonotrode 11 arranged above and a counter bearing arranged below in the form of an anvil 12. The working surfaces 13, 14 of sonotrode 11 and anvil 12 are oriented with respect to the overlapping textile junction tab 6 of PET, and the passport book card 4 of a laminated PC material. The working surfaces 13, 14 of the sonotrode 11 and anvil 12 are approximately the width of the overlap zone 21. Furthermore, the working surfaces of the sonotrode 11 and anvil 12 extend perpendicular to the plane of the drawing a along the entire length of the overlap zone 21. Due to this the weld joint 7 can be produced in one working process. The working surface 13 of the sonotrode 11 that is in direct contact with the connecting tab 6 is configured according to one of the embodiments of Figs. 5, 6 and has a profile 15. The working surface 14 of the anvil 12 is flat. For the generation of the weld joint 7, a bonding force F is applied perpendicular to the surface of the overlapping area from above, which corresponds to an opposite force F 'of the anvil 12 (see arrows). The binding time is for example 0.3 s.

In Figs. 5 and 6 two embodiments of sonotrode work surfaces 11 are reproduced. The work surface 13 of sonotrode 11 in the first embodiment not according to the invention (Fig. 5) is characterized by several elongated raised partial areas which extend in parallel with each other, in the form of a profile 15, which end at the top, so that they form edges 16 therein. This allows, due to the high surface pressure allowed due to this, a very efficient introduction of energy into the junction tab 6 and passport book card 4. The work surface 13 of sonotrode 11 in the second embodiment according to the invention (Fig. 6) is characterized by a grid of raised partial areas 17, which form parallel to the main plane of the work surface flattening 18. The grid measurement s of the partial zones corresponds approximately to the mesh width r of the connecting tongue t exile. The weld joints formed by profiling occur in weld zones 19 (see Figs. 7, 8).

Fig. 7 shows a weld joint 7 consisting of several weld zones 19, between a tongue connecting 6 of a woven PET material and the PC laminated material of the passport book card 4. The weft threads of the connecting tongue 6 extend for example perpendicular to the line of connection between the tongue and the passport book card 4 into the weld zones 19, while the warp threads 22 extend parallel thereto. The solder joint 7 was produced with a sonotrode 11 with a surface 13 according to the representation of Fig. 5.

This solder joint 7 was subjected to mechanical traction to simulate a separation of the joint between the joint tongue 6 and the passport book card 4. The joint tongue 6 and the passport book card 4 were separated for this purpose by a direction in parallel with respect to the weft yarns and in the plane of the weld joint 7. It can be seen that the separation cannot be achieved without destruction, but rather that the textile joint tongue 6 was broken by an area outside the area of Union. In this way, a falsification of the passport 1 due to separation of the passport book card 4 could be easily recognized.

In FIG. 9, a particular embodiment of a document sheet 4 is shown, which is overlapped with a connecting tab 6 by an overlapping area 21. The connecting tab is in this case made of a fabric mixed from two knitting materials, which is formed by weft threads 23 and warp threads 22. Weft threads consist of a material that can be melted during the welding process, for example in PET, and warp threads in a material that cannot be melted, for example in a cellulose or protein material, preferably cotton. The warp threads extend from the free area (which is outside the overlap area) of the connecting tongue to the overlap area. When welding, only the weft threads that extend through the overlap zone are melted, while the warp threads in this zone do not melt through the welding process, so that they maintain their shape. Due to this, a particularly fixed connection is achieved.
