Description

[0001] The invention relates to a security product with a security thread, as well as a method and a device for producing such a security product.

[0002] Such a security product may, for example, be an identification, valuables and / or security document, such as a banknote or a passport, or a precursor thereof.

[0003] A security document with a security thread and a method for its production are known, for example, from WO 2012 / 0 318 25 A1.

[0004] This publication describes a valuable and / or security document with a continuous security thread and a method for its production. Several rolls containing different films are provided. The individual films are brought together via deflection rollers and then laminated into a laminate using pressure and / or heat. Before being brought together, at least one security thread, optionally with adhesive, is applied to a central film, which is guided between at least two other films. The laminated stack of films is then individually separated to form a valuable and / or security document with a security thread. Such security products, especially ID cards or banknotes, are repeatedly subject to counterfeiting attempts in everyday life.

[0005] A security thread typically consists of a polymer carrier coated with metal on one or both sides. Parts of the security thread are demetallized, allowing the security thread to be verified, particularly in transmitted light.

[0006] It is therefore the object of the present invention to provide a security product with a security thread with increased counterfeit protection. Furthermore, the object of the invention is to provide a method and a device for producing such a security product with a security thread.

[0007] This object is achieved by a security product having the features of claim 1, by a method having the features of claim 8, and by a device having the features of claim 11. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims.

[0008] The security product according to the invention comprises, in particular, a security thread with a first thread end and a second thread end, as well as a substrate with a circumferential edge, onto or into which the security thread is applied, wherein the first thread end and / or the second thread end is arranged at a distance from the edge of the substrate that is different from zero. In other words, the first thread end and / or the second thread end is arranged at a distance from the edge of the substrate.

[0009] This makes it particularly easy to implement several additional security features on the security product, thereby increasing the security against counterfeiting.

[0010] Preferably, the non-zero distance of the first and / or second thread end from the edge of the substrate and / or the length of the security thread forms a readable security feature. This allows two additional security features to be implemented in a particularly simple manner, thereby increasing the counterfeit protection of the security product.

[0011] One aspect of the invention provides that the distance from the edge and / or the length of the security thread is selected such that it is person- and / or document-specific. A person- and / or document-specific distance from the edge and / or length of the security thread allows the realization of a security feature that can be verified quickly and easily, e.g., with the human eye as a Level 1 security feature. For example, the length of the security thread of a first security product of a first type can be formed with a first, fixed length, whereas the second length of a security thread on a second security product of a second type differs from the first length.

[0012] Preferably, the spacing and / or length of the security thread corresponds to a reference information also present on the substrate. This increases the security product's forgery security, as the security thread is applied at a specific position and / or at a specific length to correspond to the reference information, such as the number of letters in the ID card holder's name or place of birth. It is also possible for the spacing and / or length of the security thread to correspond to a checksum also present on the substrate or determinable from it.

[0013] In one embodiment of the invention, the security thread runs essentially in a straight line. This ensures uncomplicated production of the security product, as the security thread does not need to be bent or kinked.

[0014] Preferably, the substrate of the security product has a substantially rectangular shape. This also enables simple production of the security product, as the substrate can be separated later in the manufacturing process using simple means. For example, the substrate can be punched out in a simple rectangular shape.

[0015] In one embodiment of the invention, the security thread extends substantially at an angle to a side of the substrate that is different from zero degrees and from an integer multiple of ninety degrees.

[0016] This angle can be provided as a readable security feature, which is selected specifically for the person and / or document and, if applicable, corresponds to reference information also present on the substrate. Such an arrangement of the security thread further increases counterfeit security, as it creates an additional security feature.

[0017] In one embodiment of the invention, the security thread runs essentially parallel to one side of the substrate. This enables simple production of the security product, as the security thread does not need to be rotated prior to application.

[0018] Preferably, the non-zero distance of the first and / or second thread end from the edge of the substrate oriented substantially orthogonal to the security thread and / or from the edge oriented substantially parallel to the security thread forms a readable security feature. This provides a security feature that is easy to verify and read, thereby increasing the security product's counterfeit resistance.

[0019] It has proven advantageous for the security thread to adhere completely to the substrate. This ensures that the security thread does not have a loose end that protrudes beyond the substrate and is easily tampered with. This increases the counterfeit resistance of the security product.

[0020] Preferably, the security thread is arranged in a plane on or within the substrate. This enables simple production and positioning or attachment of the security thread to the substrate, since the security thread does not need to be folded around the substrate, for example.

[0021] In one embodiment of the invention, at least a first and a second security thread are applied to or into the substrate. The application of at least one second security thread enables the implementation of several new security features with minimal effort, thereby increasing the counterfeit protection of the security product.

[0022] Preferably, the distance between the security threads forms a readable security feature. This provides a simple new additional security feature, thereby increasing the counterfeit resistance of the security product.

[0023] Preferably, the security threads are arranged parallel to each other. This enables the simple, automated production of a security product with multiple security threads.

[0024] In another embodiment, the security threads are arranged coaxially to one another. This also ensures the simple production of a security product with multiple security threads.

[0025] Preferably, a first security thread is arranged parallel to an edge of the substrate, and a second security thread is arranged at a non-zero angle to this edge. This significantly increases the counterfeit security of the security product with minimal effort, as several additional security features can be implemented. It is conceivable that the lengths of the security threads, the distances between the thread ends and the edges, the distance between the security threads, and the non-zero angle each form a readable security feature.

[0026] The embodiments, advantages and effects explained in connection with the security product according to the invention also apply in the same way to the method according to the invention.

[0027] The method according to the invention comprises in particular the following steps: Providing a first roll with a carrier film on which a web of security threads is supported, and a second roll which provides a substrate web; detaching one of the security threads from the carrier film; cutting one of the security threads to produce a separated security thread with a first thread end and a second thread end; applying the security thread to the substrate web in such a way that the first end and / or the second thread end is arranged at a distance different from zero from a circumferential edge, which may still be produced, of a substrate separated from the substrate web.

[0028] This process offers the advantage of allowing a security product with increased counterfeit protection to be manufactured with a short cycle time and high precision. Another advantage is the savings in security thread material, as the security thread is not applied continuously across the substrate.

[0029] Preferably, the substrate web with the separated security threads is guided between at least two other substrate webs, resulting in a substrate web stack, and the substrate web stack is laminated, particularly by means of pressure and / or heat. This provides a simple way to provide, for example, a protective layer for the security thread. Tampering with the security thread would then require delamination, which would reveal a counterfeit security product.

[0030] Preferably, the laminated substrate web stack is cut to form a single substrate with a peripheral edge, wherein the first thread end and / or the second thread end are arranged at a distance from the peripheral edge that is different from zero. In this way, such a security product with a security thread can be manufactured with high precision and a short cycle time.

[0031] The embodiments, advantages and effects explained in connection with the security product according to the invention and the method according to the invention also apply in the same way to the device according to the invention.

[0032] The device according to the invention comprises, in particular, a first roll holder configured to receive a first roll with a carrier film, on which a web of security threads is supported, and a second roll holder configured to receive a second roll with a substrate web. Furthermore, the device has a detachment device comprising a detachment edge configured to detach the web of security threads from the carrier film, and a cutting device comprising a cutting edge or a cutting wire configured to separate the web of security threads, resulting in a separated security thread with a first and a second thread end.Furthermore, an application device is provided which comprises a handling device which is designed to apply the separated security thread to the substrate in such a way that the first thread end and / or the second thread end is arranged at a distance different from zero from a circumferential edge, which may still be produced, of a substrate separated from the substrate web.

[0033] In this way, a straightforward device is provided that is capable of producing a security product with a security thread using an efficient process.

[0034] In one embodiment of the invention, position markings for positioning the security thread are applied to the substrate web. This makes it easy to apply the individual security threads to the correct, predefined position on the substrate web without significant control effort.

[0035] In a further embodiment, a control unit is provided which comprises an optical detection device which is designed to optically detect the substrate web and / or the carrier film on which a web of security threads is supported and to communicate with the handling device in such a way that the handling device applies the separated security thread to a position on the substrate web defined by the control unit.

[0036] This enables fully automated, process-reliable, and computer-controlled production of the security product. It is also conceivable that such a design would eliminate the need for position markings for the positioning of the security thread.

[0037] Preferably, a lamination unit is provided, which is designed to laminate a substrate stack comprising several substrate webs using pressure and / or heat. Lamination increases the robustness and counterfeit resistance of the security product.

[0038] Preferably, a separating device is provided that is designed to cut the substrate web stack to produce a separated substrate with a circumferential edge, wherein the first thread end and / or the second thread end are arranged at a distance from the circumferential edge that is different from zero. In this way, a device is provided that is capable of producing a security product with increased counterfeit protection.

[0039] The security product is preferably in ID 1, ID 2, ID 3, or some other format, for example, in booklet form, similar to a passport-like item. The security product is generally a laminate of multiple substrate layers that are precisely bonded together under heat and increased pressure. These products should meet standardized requirements, for example, ISO 10373, ISO / IEC 7810, and ISO 14443. However, the security product can also be a precursor to these, e.g., just a substrate layer with a security thread applied to it.

[0040] The substrate preferably consists of a carrier material suitable for lamination. However, the substrate can preferably be formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate formed with a geminal disubstituted bis(hydroxyphenyl)cycloalkane, polyethylene terephthalate (PET), derivatives thereof, such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (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 derivatives thereof, and / or paper and / or cardboard and / or glass and / or metal and / or ceramic. In addition, the product can also be made of several of these materials.It is preferably made of PC, PVC, and PET. The polymers can be either filled or unfilled. In the latter case, they are preferably transparent or translucent. If the polymers are filled, they are opaque. The above information refers both to films to be bonded together and to liquid formulations applied to a precursor, such as a protective or topcoat. The security product is preferably produced from three to twelve, preferably four to ten, films. The films can also carry printing layers. A laminate formed in this way can then be coated on one or both sides with the protective or topcoat or with a film. The film can, in particular, be a volume hologram, a film with a surface hologram (for example, a cinematic element), or a scratch-resistant film.Overlay layers formed in this way protect a security thread arranged underneath and / or provide the document with the necessary abrasion resistance.

[0041] The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments that are not explicitly shown or explained in the figures, but which proceed and can be generated through later combinations of features from the explanatory statements, are also to be considered encompassed and disclosed by the invention.

[0042] Further features and advantages of the invention will become apparent from the following description and the accompanying drawings, to which reference is made. The drawings show: Figure 1 shows a schematic first embodiment of a security product according to the invention with a security thread, Figure 2 shows a schematic second embodiment of a security product according to the invention with two security threads and Figure 3 shows a schematically illustrated device according to the invention for producing a security product according to the invention.

[0043] Fig. 1 shows a security product 100 with a substrate 110 having a peripheral edge 108.

[0044] The substrate 110 may be, for example, an identity card, a data card of a passport or a banknote or a precursor of such products.

[0045] Personal and / or document-specific information 202, such as the cardholder's age, height, and place of birth, may be present on the security product 100. Furthermore, the security product 100 may have visible and / or invisible security features 204, such as engravings, surface embossing, micro-lettering, or even microchips.

[0046] The security product 100 has a security thread 106, which comprises a first thread end 102 and a second thread end 104. The security thread 106 is arranged on or in the substrate 110.

[0047] In the embodiment shown, the substrate 110 has a rectangular shape. However, it is also conceivable that the substrate 110 has a different shape, such as a circular shape, a triangular shape, or a polygonal shape.

[0048] Due to the rectangular shape of the substrate 110, four sides 200a, 200b, 200c and 200d result.

[0049] In the illustrated embodiment, the security thread 106 runs in a straight line. However, it is also conceivable for the security thread 106 to have a different path, such as a curved, bent, or angular path.

[0050] In the embodiment shown, the security thread 106 has the length L, which extends from the first thread end 102 to the second thread end 104.

[0051] The security thread 106 is arranged such that the first thread end 102 and the second thread end 104 are at a distance from the circumferential edge 108 that is different from zero. Alternatively, it is also conceivable that the first thread end 102 or the second thread end 104 lie on the circumferential edge and only the respective other thread end 102, 104 is arranged at a distance from the circumferential edge 108 that is different from zero.

[0052] In Fig. 1 the distances A and D from the thread ends 102, 104 to the circumferential edge 108 and the distances B and C from the security thread 106 to the sides 200a and 200c are highlighted as examples.

[0053] In the embodiment of the Fig. 1 the security thread 106 runs parallel to the sides 200a and 200c of the substrate 110; thus parallel to the two long edges running parallel to each other.

[0054] It is also conceivable that the security thread 106 runs parallel to the sides 200b and 200d of the substrate 110; thus parallel to the two short edges running parallel to each other, which are shorter than the long edges.

[0055] The distance A from the second thread end 104 to the circumferential edge 108 and the length L of the security thread 106 form readable security features which are in particular adapted to a reference information also present on the security product 100.

[0056] Additionally or alternatively, the distances B, C of the security thread 106 to the circumferential edge 108 and / or the distance D from the first thread end 102 to the circumferential edge 108 can form readable security features.

[0057] These security features can be read and checked using a scanner, a camera, or by inspection personnel, for example. This can be used not only to verify the authenticity of security products but also to monitor flawless manufacturing.

[0058] Thus, the distance of a thread end 102, 104 from the circumferential edge 108 and / or the length L of the security thread 106 can correspond to a reference information item relating to a security feature 204 also contained on the substrate 110 and / or to person-specific and / or document-specific information 202 also present on the substrate 110.

[0059] For example, the distance A can correspond to the number of letters of the cardholder's place of birth in millimeters (mm).

[0060] Furthermore, the length L of the security thread 106 and a distance A of a thread end 102, 104 to the circumferential edge 108 can be selected to be person- and / or document-specific.

[0061] For example, the length L of the security thread 106 on a driver's license can be 3 centimeters (cm) and on an ID card 5 cm.

[0062] In an alternative embodiment, the security thread 106 extends at an angle W different from zero degrees and from an integer multiple of ninety degrees to one of the sides 200a, 200b, 200c, 200d of the substrate 110.

[0063] This is in Fig. 1 indicated by the dashed line 206. The angle W can be a readable security feature that is selected specifically for a person and / or document and corresponds to a reference information that may also be present on the substrate 110.

[0064] Figur 2 shows a second embodiment of the security product 100. The second embodiment of the security product 100 is essentially the same as the first embodiment, so only the differences will be discussed below. Identical and functionally equivalent parts are provided with the same reference numerals.

[0065] On the substrate 110 in the embodiment according to Figur 2 a second security thread 106b is arranged, which has a first thread end 102b and a second thread end 104b.

[0066] Of course, it is also conceivable that more than two security threads 106 are arranged on the substrate 110.

[0067] The second security thread 106b extends at an angle W different from zero degrees and from an integer multiple of ninety degrees to the side 200c of the substrate 110.

[0068] Of course, a different arrangement of the second security thread 106b is also possible. The security thread 106b can, for example, be arranged according to the described configurations of the security thread 106 from the first embodiment.

[0069] The distance E between the first security thread 106 and the second security thread 106b, or the first thread end 102b of the second security thread 106b, forms a further readable security feature. It is also conceivable, for example, to use the distance G as a security feature.

[0070] All distances, the length of the safety threads 106, 106b and the angle W can be varied as desired.

[0071] Thus, the arrangement of one or more security threads 106 with two thread ends 102, 104 enables the formation of numerous additional security features, whereby the security against counterfeiting can be enormously increased in a simple manner.

[0072] Fig. 3 1 also shows a device 101 for producing security products with a first roll holder 120 and a second roll holder 122. A first roll 112 with a carrier film 114, on which a web of security threads 106a is supported, is received on the first roll holder 120. A second roll 116 with a substrate web 118 is received on the second roll holder 122.

[0073] The Fig. 3 The embodiment of the device 101 shown has a third roller holder 152, on which a third roller 154 with a second substrate web 138 is received, and a fourth roller holder 156, on which a fourth roller 158 with a third substrate web 136 is received. In addition, the Fig. 3 shown embodiment of the device 101 a fifth roll holder 160 on which the processed carrier film 114 is or will be wound.

[0074] Furthermore, Fig. 3 indicated that it is possible to provide or arrange further roller holders with additional rollers and tracks.

[0075] The roller receptacles 120, 122, 152, 156 are arranged such that the first and second roller receptacles 120, 122, viewed vertically, are located between the third and fourth roller receptacles 152, 156.

[0076] The device 101 comprises a detachment device 124, which has a detachment edge 126. The detachment edge 126 can be formed, for example, as a plate with an acute angle, as shown in Fig. 3 can be seen.

[0077] In addition, the device 101 has a cutting device 130 comprising a cutting edge 128. To enable a clean cut, the cutting edge 128 can be formed, for example, as a fine wire with a sharp edge.

[0078] Furthermore, the device 101 comprises an attachment device 132 having a handling device 134. The handling device 134 can be configured, for example, as a gripper or as a suction plate.

[0079] The device 101 further comprises a lamination unit 148. This can be configured, for example, as a heatable press.

[0080] In addition, the device 110 includes a separating device 150, which can be designed, for example, as a punching machine.

[0081] In addition, the device 101 shown has a control unit 146 and an optical detection device 144.

[0082] The optical detection device 144 is arranged such that it captures an image of the substrate web 118 and / or an image of the carrier film 114 with the web of security threads 106a and / or an image of the cutting edge 126. It can be configured, for example, as one or more cameras.

[0083] The control unit 146 is designed to control the entire device 101 and to communicate with and control the optical detection unit 144, the cutting device 130, the application device 132, the detachment device 124, the lamination unit 148 and the separation device 150.

[0084] The control unit 146 is also designed to control the flow rate of the individual lanes. It can be configured, for example, as a central computer.

[0085] In the following, the function of the device 101 is explained using the Fig. 3 illustrated embodiment and a method for producing a security product 100 with security thread 106 is explained.

[0086] In a first step, the carrier film 114, on which a web of security threads 106a is supported, is guided to the detachment edge 126 of the detachment device 124, which is designed to detach the web of security threads 106a from the carrier film 114. At the detachment edge 126, the web of security threads 106a is then detached from the carrier film 114.

[0087] The remaining (empty) carrier film 114 is guided to the fifth roll holder 160 and wound up there.

[0088] The detached web of security threads 106a is then guided to the cutting edge 128 of the cutting device 130 and separated in a second step. The cutting edge 128 is designed to separate the web of security threads 106a and cuts the web of security threads 106a in such a way that a separated security thread 106 is produced with a first and a second thread end 102, 104.

[0089] The cutting device 130 is controlled by the control unit 146 in such a way that the security thread 106 is severed in such a way that it is shorter than the separated substrate 110 to be produced later.

[0090] To sever the web of security threads 106a, the cutting edge 128 is moved from a rest position to a working position. After separating the web of security threads 106a, the cutting edge 128 is moved back to the rest position.

[0091] In the rest position, the cutting edge 128 is in the illustrated embodiment of the Fig. 3 below the path of safety threads 106a. In the working position, the cutting edge 128 is located above the path of safety threads 106a, so that the cutting edge 128 cuts through the path of safety threads 106a on the way from the rest position to the working position.

[0092] In a next step, the isolated security thread 106 is applied to the substrate web 118.

[0093] The handling device 134 picks up the separated security thread 106 and arranges it in a correct predefined position on the substrate web 118.

[0094] For this purpose, the control unit 146 controls the handling device 134 such that the security thread 106 is arranged such that the first thread end 102 and / or the second thread end 104 is arranged at a distance different from zero from a circumferential edge 108, which is still to be produced, of a substrate 110 separated from the substrate web 118.

[0095] Furthermore, the application of the security thread 106 is monitored by the optical detection device 144.

[0096] In the example shown, the Fig. 3 For this purpose, position markings 142 are applied to the substrate web 118 for the correct positioning of the security thread 106. In this way, a predefined position can be easily detected by the optical detection device 144. The position markings 142 can be designed, for example, as printed marks. However, it is also conceivable that correct positioning can take place without the position markings 142, albeit with increased control-technical complexity.

[0097] In the next step, the substrate web 118 with the isolated security threads 106 is guided between at least two further substrate webs 136, 138, so that a substrate web stack 140 is produced.

[0098] For this purpose, the substrate webs 118, 136, 138 are deflected by means of deflection rollers 162. As in Fig. 3As shown, additional substrate webs can be used. It is advantageous if at least a second substrate web 138 is guided over the substrate web 118 with the individual security threads 106. It has also proven advantageous if a third substrate web 136 is guided under the substrate web 118. In this way, at least one layer of protection is formed for the security thread 106, thereby increasing the security against counterfeiting.

[0099] In a next step, the substrate web stack 140 is laminated by the lamination unit 148 using pressure and / or heat to form a laminate.

[0100] In a next step, the substrate 110 is cut or punched out of this laminated substrate web stack 140; thus, it is separated.

[0101] In this case, the separating device 150 cuts the laminated substrate web stack in such a way that a separated substrate 110 with a circumferential edge 108 is produced, wherein the first thread end 102 and / or the second thread end 104 are arranged at a distance from the circumferential edge 108 that is different from zero.

[0102] Before cutting in the separating device 150, a pre-separation into substrate sheets or strips can take place, so that, for example, in the separating device 150, a plurality of substrates 110 are separated from a pre-separated substrate sheet. List of reference symbols
