Description

Method for connecting at least one connecting tab to a document sheet, method for producing a security document and security document Description:

The present invention relates to a method for producing a security document, a method for connecting at least one connection tab with a document sheet, which can be attached to the security document, and a security document. The security document may be, for example, a passport, identity card, driver's license, access control card, vehicle registration document, vehicle registration document, visa or other ID document, checkbook, gift or shopping voucher, bill of lading or other credentials or any other ID document. Preferably, the document is a passport or identity card.

Such security documents may in particular be passport documents, which are typically in booklet or book form and in which an information-storing document sheet is connected to the document. The document sheet is, for example, a passport card, which is incorporated in a passport document. The passbook card contains personalization data and other data, such as information about the issuing body. The passport card must be connected to the other sides of the passport document in such a way that a third party can not separate the card from the document in order to prevent a falsification or falsification of the document. Nevertheless, if such forgeries or falsifications are made to the document, they must be readily recognizable.

A booklet with a personalized data sheet is described, for example, in EP 1 502 765 A1. This booklet has several sheets between an envelope. The data sheet is firmly attached to the envelope of the booklet. It has a flexible layer which protrudes with an area from the data sheet. The datasheet is connected to the envelope and the remaining sheets at this area. DE 10 2008 031 654 A1 further discloses a document card which can be inserted into a security document embodied as a book. The data card is integrated into the security document by means of these two tab strips. For this purpose, through holes are introduced into the card body along an edge of the card body. Then, the card body is 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 bonded to the card body by introducing ultrasonic energy at the locations of the through holes by making connections between the two tab strips through the through holes. As a result, the tab strips are positively connected to the card body. The document card thus produced is then inserted over the tab strips in the security document executed as a book.

With the known methods, it is possible to integrate a data card in a book or book-shaped security document. However, the known manufacturing methods do not yet meet the requirements placed on them: Firstly, the method must be simple to carry out in order to produce the security document at low cost and with high yield. Furthermore, it has also been found that the book or book-shaped documents produced in this way are easy to lock, ie that they remain in an approximately half-open state without the action of an external force and can only be fully opened by the application of an external force. However, it is advantageous if the document is closed without application of an external force or remains in the fully open state. Of course, it must also be demanded that the security document must be largely forgery-proof and tamper-proof. Insofar as the terms "document" and "security document" are used in this description and in the claims, this includes, in particular, a passport, identity card, driver's license, access control card, vehicle registration document, vehicle registration document, visa or other ID document, checkbook, gift certificate. or shopping voucher, bill of lading or other proof of entitlement or another ID document. Preferably, the (security) document is a passport or identity card. Most preferably, the (security) document is book or book-shaped, ie it contains several pages that can be exfoliated. The document sheet can in particular form a map of a (security) document. If the (security) document is a passport, a document sheet contained therein is preferably a passport card. The (security) document is formed from a document body and a document sheet, which are connected via at least one connection tab. The document body can be in book or booklet form, ie have several pages that can be opened. For example, the security document may be a passport that has multiple visa pages.

Insofar as the terms "documentary sheet" and "sheet" are used in this description and in the claims, they are understood to mean flat, preferably rectangular, carriers for information to be displayed. These supports can be as thin and thus flexible as a paper sheet or thin plastic film or even thicker than and less flexible than a paper sheet or plastic film, for example like a piece of cardboard or like a card that is still twistable, however can not be rolled anymore. Furthermore, this also means rigid plates that can not be bent or twisted practically. Thus, the (document) bow can also be in the form of a card. If the document is a passport document, the document sheet is preferably a passport card. The format of the (document) sheet depends on the document into which it is to be integrated. For example, it may have one of the formats ID 1, ID 2 or ID 3 according to ISO / IEC 7810. The (document) sheet may further be made of a material suitable for the purpose of the invention, for example of a plastic (polymer), paper, cardboard, glass or other materials or mixtures of these materials, and optionally filled with reinforcing materials. The thickness of the document sheet is preferably 250 to 950 μm. The method according to the invention relates to the joining of at least one connecting tab formed from a textile material with a document sheet storing information. 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 strap is different according to the invention from the sheet material forming the document sheet. The sheet may in particular be designed so that it incorporates by means of the at least one connecting tab into a booklet or book which consists of sheets, foils and, if appropriate, booklets and / or book covers and / or book spines. bar or can be bound together with other sheets, slides and, if necessary, staples or book covers and / or book or book spines to a book or book.

The inventive method comprises, preferably in the following order, the following method steps: a) overlapping arranging the at least one connecting tab and the document sheet so that an overlap region 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 for producing a security document. This method comprises the following method steps: A) providing the information-storing document sheet and the at least one connecting tab formed from a textile material, the textile material of the at least one connecting tab being different from the sheet material forming the document sheet; B) overlapping the at least one connecting tab and the document sheet such that an overlapping area of the at least one connecting tab with the document sheet is formed, C) welding the at least one connecting tab and the document sheet in the overlapping area; and D) attaching the document sheet to the document body of the security document via the at least one connection tab.

The present invention also relates to a book or staple security document having a document body having one or more book or staple pages, and at least one connecting tab connected to the document body and a document sheet storing information. The document sheet is connected to the at least one connecting tab by means of a welded connection, wherein the at least one connecting tab is formed from a textile material and wherein the textile material of the at least one connecting tab is different from the sheet material forming the document sheet. The present invention is based on the idea that a combination of a document sheet with the document body of a security document by means of a textile connection tab is advantageous because it ensures a flexible connection of the document sheet to the document body and the document without an externa ße- force can be easily closed or kept open. However, it was surprising that a solid, in particular cohesive connection (ie, a material connection of the materials with each other) between the document sheet and the connecting strap is also accessible if the sheet material and the material of the Verbindungsla- see are not identical, because a secure material connection was to be expected only when welding identical materials together.

By forming the connecting tab as a textile material is further ensured that the security document, in which the document sheet is integrated by means of the connecting tab, in a simplified manner manageable by the document can be folded and unfold easily without locking it and without returning to a half-closed state again. Because the textile connecting strap has the flexibility required for this purpose. Also by the welding process, the connection tab does not lose its flexibility, since the welding does not extend to the flexible area. Furthermore, the welding method for connecting the connecting tab to the document sheet achieves a material connection between the connecting tab and the document sheet, which ensures that the document sheet can no longer be removed from the security document in a nondestructive manner when it is detached from the connecting tab. For this purpose, the material of the connecting strap is directly connected to the material of the document sheet via at least one connecting point. Furthermore, it has been found that the use of different materials for the document sheet and the connecting tab allows an optimization also in terms of the most favorable for the selection of suitable components materials. Because it has been determined that a restriction to certain materials with regard to a good weldability does not exist. With the secure cohesive connection a forgery or falsification of the security document is virtually impossible, at least with regard to the said exchange of the document sheet. This compound is easy to produce and therefore cost-effective and essentially not prone to error because of a small number of process steps required for this purpose. As a result of the welding, a pattern present in the overlapping area in the document sheet, for example a printed image in the form of alphanumeric characters, becomes visible through the textile connecting strip. This can be a security feature for the documentary sheet. During welding, the textile properties lost in the connection area. In the hinge area, ie outside the connection area, they remain intact.

The textile material of the connecting strap can be designed in any desired manner. For example, it may be formed by a fabric in the form of a woven, knitted, knitted or the like or in the form of a felt or nonwoven, provided that it has the required tear strength. The material is preferably formed from a composite of filaments, in particular fibers, yarn, threads or the like, which are arranged in an ordered manner in the case of a woven, knitted fabric, knit or the like, while the filaments of a felt or nonwoven , For example, fibers are arranged disorderly. Preferably, the textile material is formed by a fabric, in particular with warp and weft threads.

The textile material of the connecting strap may in particular consist of or contain one or more fusible materials in order to enable the welding process. The at least one meltable textile material is preferably made of plastic (polymer), more preferably of thermoplastic material. It has proven to be particularly advantageous to use a polyester, for example polyethylene terephthalate (PET), or a thermoplastic polyurethane (TPU) as the thermoplastic, because these materials readily spin into yarns or the like and then continue to form the textile material process. The textile material may preferably be formed at least partially from polyester. The melting point or glass transition temperature of the fusible material is preferably adapted to the material properties of the document sheet. The melt or glass transition temperatures of the connection tab and the document sheet are preferably similar in size (for example, within a temperature range of 50 ° C), so that the welding process is error-free and easy to carry out. In addition, the textile material may be partially made of cotton, i. this included. For example, it may consist of a cotton-polymer blend, especially a cotton-polyester blend.

In a further preferred embodiment variant of the present invention, the textile material of the at least one connecting strap is formed from two different materials (blended fabric), one of which, when welded to the document sheet, at least melts and the other material in the welding process with the document sheet does not connect, ie does not melt, so that no welded connection of this other material is formed with the document sheet. For example, the warp threads of a blend fabric can remain unchanged during welding, while the weft yarns melt or melt and firmly connect with the material of the document sheet. The weft threads extend in this case from the free (not in the overlapping area) edge of the connecting strap in the overlapping region. The fact that they are not on or melted, the strength of the material of the connecting plate in the transition region between the free edge and the overlap area is maintained.

For example, in a first preferred embodiment, the materials of the at least one connecting strap according to the last-mentioned embodiment variant may have different melting points or glass transition temperatures. For example, a first material may have a first melting point or a first glass transition temperature such that it melts or melts under the conditions of the welding process, and a second material has a second melting point or a second glass transition temperature that is significantly higher, so that the second Material does not melt or melt under the same welding conditions. In a second preferred embodiment of the last-mentioned embodiment variant, the textile material may be formed of at least two materials, of which a first material has a melting point or a glass transition temperature, so that it melts or melts under the conditions of the welding process, and of which a second material is not a fusible material (in particular not a thermoplastic), but for example a material other than plastic, such as a cellulosic material or a protein, for example a wool material, or a thermosetting plastic or carbon, glass fiber, inorganic or metallic fibers (wires) This second material does not melt or melt during the welding process. In the two aforementioned cases, the second material does not melt during the welding process and thus remains unchanged, so that the internal strength of the at least one connecting strap is not impaired by the welding process. Preferably, only a single connection tab is used for connecting the document sheet to the document body of the security document. In principle, of course, a plurality of connecting straps can be used for this connection, for example by superimposing a plurality of such connecting straps. For the sake of simplification and reference to the relevant embodiments, reference will now be made to a connecting link.

The connecting strap is preferably an elongate, in particular rectangular, sheet which is sufficiently wide in order to be able to overlap the document sheet at the edge so that a firm welded connection can be produced and to form a connection area with the security document , Preferably, the connecting tab in a direction of extent is the same length as the document sheet, so that the connecting tab extends over an entire edge length of the document sheet and not beyond. The connection tab overlaps the document sheet in an overlap area so that another connection area of the connection tab projects laterally beyond the document sheet. This connection area is used for the subsequent connection of the unit of connection tab and document sheet connected thereto with the document body of the security document. The connection region may in particular be strip-shaped. This free edge has an elongated interface which is available for connection to the document body. The connecting strap may have at least one security feature, for example one or more security threads.

The document sheet may be made of one or more materials. Preferably, the document sheet is in the form of a laminate, which is made of several laminate layers by lamination. In principle, however, the document sheet can also be produced by injection molding or extrusion or another production method. The document sheet is preferably made of one or more plastics (polymers), in particular polycarbonate (PC), more particularly 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), 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 derivatives thereof, or of paper and / or cardboard or of mixtures of the abovementioned materials. It is preferred that the sheet material is at least partially formed of polycarbonate or a polycarbonate derivative. Preferably, the document sheet is a laminate formed of multiple layers. One or more layers of the laminate may consist of PC or PC7TPU / PC or contain these materials. Other layers may all consist of or contain the same material or different materials. The polymers may 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 may therefore be, for example, a pigment. The layers can be colored or colorless. The outer layers of the document sheet (overlay foils) can in particular be colorless transparent and have a high abrasion resistance. The laminate is preferably formed from a thermoplastic material which at least partially melts or melts in the welding process in the at least one connecting region.

In a preferred embodiment of the present invention, the welding is carried out by means of a sound waves in the overlapping region-registering method. In particular, the welding process may be an ultrasonic welding process. For this purpose, a sonotrode is used, which is displaceable in ultrasonic vibrations. For the welding process, the sonotrode is placed on the connection area of the connection partner to be welded (connection tab and document sheet), so that the energy contained in the ultrasonic vibrations in the connection area is registered in the materials of the connection partners. As a result, the materials to be joined are heated, so that at least one material of the connection partners melts and the connection is brought about. In principle, other connection mechanisms are also conceivable, for example an intimate approximation of the materials to one another, so that atomic (chemical) connections can occur. During the welding process, the sonotrode can be pressed onto the connection point by applying a pressing pressure in order to be able to enter the energy into the connection area as efficiently as possible. For this purpose, an abutment (machine table, anvil) may be arranged opposite to the sonotrode, to which the superimposed connection partners are placed and pressed by the sonotrode. In the sonotrode For example, ultrasound is preferably generated by means of a piezocrystal, from which the mechanical vibrations arising in it are transmitted to the working surface of the sonotrode.

In one embodiment, the sonotrode can have a plane working surface, so that the connecting tab is welded to the document arc in the entire area of the working surface of the sonotrode. In principle, the working surface of the sonotrode can be just as large as the overlapping area of the connecting tongue with the documentary sheet. Alternatively, the working surface of the sonotrode may also be smaller (alternatively larger) than the overlap region. If the work area is smaller than the overlap area, a weld is created that is smaller than the overlap area.

In a preferred development of the present invention, the connecting tab and the document sheet are welded together in the overlapping area in at least two mutually spaced-apart welding areas. For this purpose, the working surface of the sonotrode is provided with a profiling with projecting subareas, via which the energy is entered only in the welding areas at the connection point, because only these subareas are in direct contact with the connection point. This ensures that not the entire overlap area of the connection tab with the documentary sheet is used for the connection. In particular, if the textile material of the connecting lug is formed exclusively of fusible material, the strength of the connecting plate is not affected in this way during welding, because the material is only partially melted, while intermediate areas not melted, but at least not melted. This prevents that the filament structure is completely destroyed in the transition between the free edge of the connecting plate and the overlapping area during the welding process, so that the strength of the material and its flexibility in the hinge area are largely retained. Preferably, the spaced apart welding areas are arranged like a grid. More preferably, the grid corresponds to the distance between adjacent threads, fibers or meshes. Thus, the structure of the working surface of the sonotrode may be formed in relation to the weave.

In a preferred embodiment of this development, the at least two mutually spaced welding areas are elongated and arranged parallel to each other. Basically, the welding areas in another preferred embodiment this development may also be punctiform and arranged, for example, in a regular grid pattern. In the two mentioned embodiments, the raised portions of the sonotrode are shaped accordingly to form said forms of welds. In yet another preferred embodiment of this development, the spaced apart welding areas may also be formed in the form of information-storing characters, for example, alphanumeric characters or symbols or the like, such as letters, pictures or in the form of micro-writing. The welded joints between the connecting tab and the document sheet are formed in this case in the form of these characters. This embodiment thus represents a security feature that can not be readjusted easily. Since the textile material of the connection tab becomes transparent when transparent materials are used during welding, the weld areas can be made well visible by using a colored sheet material. Alternatively, it is also possible to produce a coherent welding area with a correspondingly shaped working surface of the sonotrode, which is designed in the form of a pattern of raised partial area structures on the working surface of the sonotrode, for example in FIG

Shape of diamond-shaped patterns or the like. The raised portions on the sonotrode may be flattened or tapered.

The sonotrode is preferably placed on the side of the stack of the connecting tab and the document sheet, preferably pressed, on which the connecting tab is located, i. it is in direct contact with the connecting strap during the welding process. In principle, it is also conceivable to introduce energy into the connection partners from the side of the documentary sheet. The former is preferred because the textile material is compacted by the direct contact with the sonotrode, so that an intimate contact of the connection partners comes about. The joining time depends on the input power and the type of material to be welded. Typically, the joining time is 0.1 to 2 s, preferably 0.2 to 0.4 s.

The unit of the document sheet and the connecting tab, which are firmly connected, can be connected to the document body of the security document. If the security document is in the form of a booklet or book, it has a book or book spine. This also includes the fold area of a booklet. The unit from the document sheet and the connecting tab is in accordance with method step D of the method connected to the document body for producing the security document via the connection tab, preferably in the area of the staple or book spine. For this purpose, the free edge of the connecting strap can be connected to the document body, for example by means of an adhesive, sewing or welding process.

The inventive method for producing the security document, comprising the method steps A, B and C, according to which the unit is made of interconnected connection tab and document sheet, further includes the method step D, after which the connection tab is connected to the document body. This process step can be carried out after the connection between the connection tab and the documentary sheet has been made, i. E. after the document sheet has been completed, in particular individualized, for example personalized, and has been connected to the connecting strap. For this purpose, the document sheets created for the respective end purpose are connected to the document body at any location (and not only at the place of production of the document sheets). The result is the following procedure in the order given:

A) providing the information storing document sheet and the

at least one connecting tab formed from a textile material

B) overlapping the at least one connection tab and

of the documentary sheet, so that an overlap area of at least

a connection tab is formed with the document sheet

C) welding the at least one connecting tab and the document sheet in the overlapping area

D) connecting the at least one connection tab to the document body of the security document to the document sheet on the

Attach document body

Alternatively, the connection of the connection tab to the document body can also be established before it is connected to the documentary sheet, ie between method steps A and B, so that the connection of the documentary sheet with the document lasche after the connection takes place in the document body. The result is the following procedure in the order given:

A) providing the information storing document sheet and the

at least one connecting tab formed from a textile material

D) connecting the at least one connection tab to the document body of the security document

B) overlapping the at least one connection tab and

of the documentary sheet, so that an overlap area of at least

a connection tab is formed with the document sheet

C) Welding the at least one connecting tab and the document sheet in the overlapping area If, according to a preferred embodiment described above, a welded connection is produced, for example in the form of a security feature between the connecting tab and the documentary sheet, the former procedure is advantageous, since the connecting of the connecting tab to the documentary sheet and the incorporation of this unit into the document body may take place at different locations, in which case the incorporation of the unit into the document body need not necessarily take place in a particular security environment. Because the manufacturing steps required for the production of the security features (production of the document sheet and connection of the connection tab with the document sheet) are performed successively with the interposition of step B, while the subsequent step of integrating the unit in the document body (step D) can take place separately. This allows a more flexible logistics than when method step D is performed between steps A and B. On the other hand, document bodies can be kept in stock when inserting the connection tab into the document body (step D) between steps A and C, especially if the connection tab is between other sides of the document body or between other pages and the book cover of the body of the document, as with a passport. The connecting tab (possibly together with the document sheet) can be inserted into a book or stapled document body so that the sheet forms an inner side of the security document. The document body in this case has more pages and possibly a book or book spine. If appropriate, the connecting strap can be inserted into the document body which has not yet been completed, in that, together with the connecting strap, the sides and optionally the book or book spines are connected together.

In one embodiment of the present invention, the connection tab is located on the inside of the book or booklet, preferably in the region of its fold. The document sheet can also be attached as an outer page via the connecting link (instead of a book cover, a magazine cover). In this case, the connection tab can form the book or book spine (the Fälzelband). The document sheet in this embodiment can be provided with security features, in particular with data, preferably personalization data. Moreover, these security features, in particular data and in particular personalization data, are preferably arranged on the side of the documentary sheet which faces the inside of the book or booklet, ie not on the outside of the book or booklet. Not only the document sheet can be connected in this embodiment with the connecting tab by means of ultrasound but also another outer side.

In production, the connecting straps and document sheets can each be brought together and welded together. Alternatively, they can also be processed in a roll-to-roll system. For this purpose, the corresponding roll materials for the connection flap and the document sheet are present, which are brought together in a suitable manner (provided and arranged one above the other in matching fashion) and then welded together. Thereafter, the materials of the connection tab and the document sheet are welded together in the overlapping area. Finally, these units are separated from the roll materials.

The document sheet is typically used to identify a person or thing. Therefore, it is preferably designed as an individualizing, in particular personalizing document. For this purpose, the document sheet security features, such as a picture of the person, data to that person or to the item in plain text or in coded form or by means of a suitably designed form, which is hardly or hardly imitable, such as data reproduced in special luminescent colors, for example in alphanumeric representation, or tilts, holograms, special printed patterns, such as guilloches, variable colors and the like, up. Furthermore, the document sheet can also be designed as an RFID document (radio frequency identification) with an antenna and an RFID semiconductor chip. Further, the document sheet may also include electronic components such as electronic displays, sensors such as touch sensors, and the like. The present invention will be explained in more detail with reference to the figures described below.

The security document 1 shown in FIG. 1 is, for example, a passport. This is from an au ßenseitigen book cover (-rücken) 2, for example made of cardboard, several pass pages 3a, 3b, 3c, ... and the document sheet 4, in the present case a passport card from a PC laminate formed. The book cover 2 may have a hinge 5, in the region parts of the book cover 2 abut. For example, the book cover 2 of two rigid mutually adjacent parts 2a, 2b, which are interconnected by means of a flexible envelope by the envelope strikes the parts. The book cover 2 can be provided on the outside with an emblem, for example of the issuing state.

On the inside, a plurality of document pages 3a, 3b, 3c, ... are connected to the book cover 2 for the reception of sight notes and the passport card 4. The book cover 2 and the document pages 3a, 3b, 3c,... Form a document body 20.

The passport card 4 is connected via a connecting plate 6 with the document pages 3a, 3b, 3c, ... and the book cover 2. For this purpose, the passport card 4 is connected in accordance with the invention manner via a welded joint 7 with the connecting plate 6. The passport card 4 is disposed between the book cover 2 and an inner document page 3a. For the connection, these components are sewn together. The seam 8 (a thread) passes through the document pages 3a, 3b, 3c, the connecting tab 6 and the book cover 2 in the region of the hinge 5 and connects them together. In order to anchor the seam 8 in the spine 2, a Fälzelband 9 made of a flexible material is glued on the hinge 8.

The document pages 3a, 3b, 3c, ... represent the visa pages of the passport 1. They are, apart from a security printing in the form of guilloches, watermarks and possibly an identification number, not provided with other security features or other printing features.

The passport card 4 has various security features and personalizes in particular the passport holder. This is a photo of the holder whose personal data are in clear step and other security features. The passbook card 4 can also be equipped as an RFID document with an antenna and an RFID Hableiterchip and optionally equipped with electronic components. The connection tab 6 is made of a woven material of thermoplastic PET. As a result, it is flexible, so that the passport 1 can be easily opened and closed. The PET has a melting point or a glass transition temperature, which allows a welded connection with the passbook card 4 can be made by the material of the connecting plate 6 on or even melted. For another, the passport card 4 is made of a fusible material, namely in the form of a laminate of PC, which has thermoplastic properties. This material also melts on energy input or even on. The formed welded joint 7 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 (preferably the front of the passport 1) of the book cover 2 of the passport 1 is formed in this case by the passport card 4. The passbook card is preferably provided with the data on the inward facing side (to the document pages 3a, 3b, 3c, ...). The other half of the book cover 2 (preferably the back of the passport 1) is formed as part 2a as in the embodiment of FIG. In this case, the connecting strap 6 is replaced by the folding strap 9 shown in FIG. 1. The part 2 a of the cover 2, like the passport 4, is connected via a

Welded joint 7 connected to the connecting plate 6. In Fig. 3, a unit of connecting plate 6 with the passport card 4 is shown schematically in plan view. The overlapping area 21 between the connecting tab 6 and the passbook card 4 extends over the entire edge length of the passport card 4, since the connecting tab 6 is as long as the edge length. The reproduced in Fig. 4 representation of an ultrasonic welding apparatus 10 shows an overhead sonotrode 1 1 and a lower abutment in the form of an anvil 12. The working surfaces 13, 14 of the sonotrode 1 1 and the anvil 12 are to the unit of the overlapping arranged textile Connecting tab 6 made of PET and passbook card 4 aligned to a PC laminate. The work surfaces 13, 14 of the sonotrode 1 1 and the anvil 12 have approximately the width of the overlap region 21st For putting in addition, the working surfaces of the sonotrode 1 1 and the anvil 12 extend perpendicular to the plane along the entire length of the overlap region 21st As a result, the welding compound 7 can be produced in one operation. The working surface 13 of the standing with the connecting plate 6 in direct contact sonotrode 1 1 is executed according to one of the embodiments of Fig. 5, 6 and has a profiling 15. The working surface 14 of the anvil 12 is flat. In order to produce the welded connection 7, a joining force F is applied from above perpendicular to the surface of the overlapping region, which corresponds to a counterforce F 'of the anvil 12 (see arrows). The joining time is for example 0.3 s.

In Fig. 5, 6, two embodiments of working surfaces of sonotrodes 1 1 are shown. The working surface 13 of the sonotrode 1 1 in the first embodiment (FIG. 5) is characterized by a plurality of mutually parallel elongate raised portions in the form of a profiling 15, which taper at the top so that they form there cutting 16. This allows because of the high surface pressure thereby enabled a very efficient entry of energy in the connecting plate 6 and the passbook card 4. The working surface 13 of the sonotrode 1 1 in the second embodiment (Fig. 6) is characterized by a grid of raised portions 17, the form flattening 18 parallel to the main plane of the working surface. The grid dimension s of the partial areas corresponds approximately to the woven mesh width r of the textile connecting flap. The welded joints formed by the profiling are produced in welding areas 19 (see FIGS. 7, 8).

In Fig. 7 is a welded joint 7, consisting of a plurality of welding areas 19, see between a connecting plate 6 of a woven fabric made of PET and the PC laminate of

Passbook card 4 shown. Weft threads of the connecting strap 6 extend approximately perpendicular to the connecting line between the connecting strap and the passbook card 4 into the welding regions 19, while the warp threads 22 extend parallel thereto. The welded connection 7 was produced with a sonotrode 11 having a working surface 13 as shown in FIG.

This welded joint 7 was subjected to mechanical tension to simulate a loosening of the connection between the connecting plate 6 and the passbook card 4. The connection For this purpose, the fastening tab 6 and the passbook card 4 were torn apart in a direction parallel to the weft threads and in the plane of the welded connection 7. It can be seen that the detachment can not be achieved in a non-destructive manner, but that the textile connecting strap 6 tears in a region outside the connection region. This would be a falsification of the passport 1 by removing the passport card 4 readily apparent.

FIG. 9 also shows a special embodiment of a document sheet 4 overlappingly connected to a connecting tongue 6 in an overlapping area 21. The connecting strap is formed in this case by a mixed fabric of two fabric materials, which is formed by weft threads 22 and warp threads 23. The weft threads consist of a material which is meltable during the welding process, for example of PET, and the warp threads of a non-fusible material, for example of a cellulose material or of protein, preferably of cotton. The warp threads extend from the free area (outside the overlapping area) of the connecting tongue into the overlapping area. During welding, only the weft threads which extend exclusively in the overlapping area melt, whereas the warp threads in this area do not melt during the welding process, so that they retain their shape. This creates a particularly strong connection.
