Abstract

In the process for manufacturing documents with security marks (7) using an adhesive (3) that can be activated by ultraviolet light or electron irradiation, a film web (2) bearing the security marks (7) is coated with an adhesive (3), which can be activated by UV light or electron irradiation, said adhesive (3) being subsequently activated by UV light or electron irradiation, and security marks (7) are punched out of the film web (2), said security marks being bonded to the substrate (5) immediately thereafter, still in the punching and bonding unit (6). A device is also disclosed for carrying out the process, in which one supporting surface of a matrix is coated with a release agent, in order to prevent the adhesion of the film strip (2), which is coated with adhesive (3), in the punching and bonding unit (6). <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Dokumenten, die ein Substrat und mindestens eine Sicherheitsmarke aufweisen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for producing documents which have a substrate and at least one security mark, according to the preamble of patent claim 1.

Ein derartiges Verfahren ist bereits bekannt (EP-A-401 466). Bei dem bekannten Verfahren wird zuerst aus einem Schichtenverbund ein Teil einer Sicherheitsmarke ausgestanzt. Nach dem Ausstanzen wird diejenige Seite dieses Sicherheitsmarkenteils mit einem Kleber versehen, an der die Verbindung mit dem Substrat, beispielsweise einer Papierbanknote, in einem spƤteren Aufklebevorgang stattfinden soll. Als Kleber dient ein mit WƤrme aktivierbarer HeiƟkleber. Die WƤrme wird durch den Schichtenverbund der Sicherheitsmarke hindurch auf das Klebermaterial Ć¼bertragen. Dabei hat sich gezeigt, daƟ die verhƤltnismƤƟig engen Temperaturtoleranzen nicht immer gut eingehalten werden kƶnnen, sondern sehr von der Dicke und dem Aufbau der Einzelschichten des Schichtenverbunds der Sicherheitsmarke abhƤngen. Vielfach entwickelt der Kleber noch keine genĆ¼gende Klebekraft oder es werden Strukturen der Sicherheitsmarke zerstƶrt, welche die Sicherheitsfunktion sicherstellen sollen. Das vorbekannte Verfahren ist daher hinsichtlich der ZuverlƤssigkeit des hergestellten Erzeugnisses noch mangelhaft.Such a method is already known (EP-A-401 466). In the known method, a part of a security tag is first punched out of a layered composite. After the punching out, that side of this security tag part is provided with an adhesive on which the connection to the substrate, for example a paper banknote, is to take place in a later adhesive process. A heat-activated hot-melt adhesive serves as the adhesive. The heat is transferred through the laminate of the security mark to the adhesive material. It has been shown that the relatively narrow temperature tolerances cannot always be adhered to very well, but depend very much on the thickness and the structure of the individual layers of the layered composite of the security mark. In many cases, the adhesive does not develop sufficient adhesive strength or structures of the security mark are destroyed, which should ensure the security function. The known method is therefore still deficient in the reliability of the manufactured product.

Dies wirkt sich vor allem bei fƤlschungssicheren Banknoten, also solchen Dokumenten aus, welche einen erheblichen Wert besitzen.This has an impact above all on counterfeit-proof banknotes, i.e. documents that have considerable value.

DarĆ¼ber hinaus ist es bekannt (SPIE Vol. 1210 Optical Security and Anticounterfeiting Systems, 1990, Seiten 14-19), einen durch UV-Licht aktivierbaren Kleber im Druckverfahren auf eine Banknote aufzubringen und anschlieƟend durch UV-Bestrahlung vorzuaktivieren. Danach wird eine beschichtete Folie, deren Schicht die Sicherheitsmarken enthƤlt, auf das Kleberbild gepreƟt und mit diesem verklebt. AnschlieƟend wird die Kleberfolie abgezogen. Die Schicht reiƟt am Rand der Klebestelle ab, so daƟ das transferierte Bild vielfach eine mangelhafte RandschƤrfe aufweist. Abgesehen davon, daƟ dies Ƥsthetisch unbefriedigend ist, kƶnnen sich in Banknoten-PrĆ¼fgerƤten auch Erkennungsprobleme ergeben.In addition, it is known (SPIE Vol. 1210 Optical Security and Anticounterfeiting Systems, 1990, pages 14-19) to apply an adhesive which can be activated by UV light to a banknote in the printing process and then to preactivate it by UV radiation. Then a coated film, the layer of which contains the security marks, is pressed onto the adhesive image and glued to it. The adhesive film is then removed. The layer tears off at the edge of the glue point, so that the transferred image often has poor edge sharpness. Apart from the fact that this is aesthetically unsatisfactory, recognition problems can also arise in banknote checking devices.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Gattung dahingehend zu verbessern, daƟ Sicherheitsmarken auf Dokumente derart applizierbar sind, daƟ die Gefahr unbrauchbarer mit Sicherheitsmarken versehener Dokumente vermindert wird. Hierdurch kann die HerstellungsproduktivitƤt verbessert werden.The invention has for its object to improve a method of the type mentioned in such a way that security marks can be applied to documents in such a way that the risk of unusable documents provided with security marks is reduced. This can improve manufacturing productivity.

Die Erfindung ist im Anspruch 1 gekennzeichnet und in UnteransprĆ¼chen sind bevorzugte Ausbildungen derselben beansprucht.The invention is characterized in claim 1 and preferred embodiments thereof are claimed in subclaims.

GemƤƟ der Erfindung wird zuerst ein durch UV- oder Elektronenstrahlen aktivierbarer Kleber auf das Folienband aufgetragen, worauf die Kleberschicht mittels UV- oder Elektronenstrahlen aktiviert wird. Danach erfolgt das Ausstanzen der mit dem aktivierten Kleber versehenen Sicherheitsmarke aus dem Folienband. Die Sicherheitsmarke wird schlieƟlich auf das Substrat aufgedrĆ¼ckt, um dort festzukleben.According to the invention, an adhesive that can be activated by UV or electron beams is first applied to the film strip, and then the adhesive layer by means of UV or electron beams is activated. This is followed by punching out the security tag provided with the activated adhesive from the film strip. The security mark is finally pressed onto the substrate in order to stick there.

Gegebenenfalls wird das mit der Sicherheitsmarke bereits versehene Substrat zusƤtzlich mit UV- oder Elektronenstrahlen bestrahlt, wodurch die AushƤrtung des Klebers begĆ¼nstigt wird.If necessary, the substrate already provided with the security mark is additionally irradiated with UV or electron beams, which promotes the curing of the adhesive.

Nachfolgend wird ein AusfĆ¼hrungsbeispiel der Erfindung anhand der Zeichnung nƤher erlƤutert; dabei zeigen:

  • Figur 1 eine Vorrichtung zur DurchfĆ¼hrung des Verfahrens,
  • Figur 2 ein Folienband mit Sicherheitsmarken,
  • Figur 3 eine einzelne Sicherheitsmarke und
  • Figur 4 ein Werkzeug zum Stanzen und Aufkleben.
An exemplary embodiment of the invention is explained in more detail below with reference to the drawing; show:
  • FIG. 1 shows an apparatus for performing the method,
  • FIG. 2 a film strip with security marks,
  • Figure 3 is a single security mark and
  • Figure 4 shows a tool for punching and gluing.

GemƤƟ Figur 1 beschichtet ein Beschichtungswerk 1 ein Folienband 2 einseitig mit dem Kleber 3. Der Kleber 3 ist ein Kaltkleber, der im Ausgangszustand flĆ¼ssig, aber nicht klebrig ist und der erst durch Bestrahlung mit einer ultraviolettes Licht aussendenden ersten UV-Quelle 4 klebrig wird. Das mit einer Sicherheitsmarke zu versehende Substrat 5 kann in Form von Bogen oder in Rollenform vorliegen. Dabei handelt es sich beispielsweise um GroƟbogen, die eine Anzahl von bereits gedruckten, aber noch nicht zerschnittenen Banknoten enthalten.According to FIG. 1, a coating unit 1 coats the film 3 on one side with the adhesive 3. The adhesive 3 is a cold adhesive which is liquid but not sticky in the initial state and which only becomes sticky when irradiated with an ultraviolet light-emitting first UV source 4. The substrate 5 to be provided with a security mark can be in the form of a sheet or in the form of a roll. These are, for example, large sheets that contain a number of banknotes that have already been printed but not yet cut.

Der Kleber 3 kann auch ein Kleber sein, der durch Elektronenbestrahlung aktivierbar ist. An die Stelle der UV-Quelle 4 tritt dann eine Elektronenstrahl-Quelle.The adhesive 3 can also be an adhesive that can be activated by electron radiation. The UV source 4 is then replaced by an electron beam source.

Das Folienband 2 ist ein Sicherheitsmarken enthaltendes Band, das spƤter noch beschrieben wird.The film tape 2 is a tape containing security marks, which will be described later.

Das einseitig mit Kleber 3 beschichtete Folienband 2 und das Substrat 5 werden einem Stanz- und Klebewerk 6 zugefĆ¼hrt, wobei die mit dem Kleber 3 beschichte Seite des Folienbands 2 dem Substrat 5 zugekehrt ist. Im Stanz- und Klebewerk 6 werden aus dem Folienband 2 Sicherheitsmarken 7 ausgestanzt und auf das Substrat 5 geklebt.The film strip 2 coated on one side with adhesive 3 and the substrate 5 are fed to a stamping and gluing unit 6, the side of the film strip 2 coated with the adhesive 3 facing the substrate 5. In the punching and gluing plant 6, security marks 7 are punched out of the film strip and glued to the substrate 5.

Das Folienband 2, aus dem nun die Sicherheitsmarken 7 bereits ausgestanzt sind, wird auf einer Haspel 8 aufgerollt. Das mit den Sicherheitsmarken 7 versehene Substrat 5 wird einer nicht dargestellten Schneideinrichtung zugefĆ¼hrt, in der das bogenfƶrmige oder endlose Substrat 5 in die einzelnen Dokumente aufgeteilt wird. Vorteilhaft kann das mit den Sicherheitsmarken 7 versehene Substrat 5 zuvor noch der Bestrahlung durch eine zweite UV-Quelle 9 ausgesetzt werden. Das hat den Vorteil, daƟ der Kleber 3 vollstƤndig aushƤrtet, so daƟ danach eine besonders innige und dauerhafte Verbindung zwischen den Sicherheitsmarken 7 und dem Substrat 5 besteht. Im Falle der Verwendung eines durch Elektronenbestrahlung aktivierbaren Klebers 3 tritt an die Stelle der zweiten UV-Quelle 9 eine zweite Elektronenstrahlquelle.The film strip 2, from which the security marks 7 have already been punched out, is rolled up on a reel 8. The substrate 5 provided with the security marks 7 is fed to a cutting device, not shown, in which the arcuate or endless substrate 5 is divided into the individual documents. Advantageously, the substrate 5 provided with the security marks 7 can previously be exposed to the radiation from a second UV source 9. This has the advantage that the adhesive 3 hardens completely, so that there is then a particularly intimate and permanent connection between the security marks 7 and the substrate 5. If an adhesive 3 that can be activated by electron radiation is used, a second electron beam source replaces the second UV source 9.

In der Fig. 2 ist ein Beispiel fĆ¼r das Folienband 2 dargestellt. Es besteht aus einer transparenten TrƤgerschicht 11, auf der in der angegebenen Reihenfolge eine Zwischenschicht 12, eine erste Lackschicht 13, eine Reflexionsschicht 14 und eine zweite Lackschicht 15 aufgebracht sind. Dieser Aufbau ist aus EP-A-0 401 466 bekannt. Sie enthƤlt eingeprƤgte Beugungstrukturen 16, die sich im Folienband 2 mehrfach wiederholen.An example of the film strip 2 is shown in FIG. 2. It consists of a transparent carrier layer 11, on which an intermediate layer 12, a first lacquer layer 13, a reflection layer 14 and a second lacquer layer 15 are applied in the order given. This structure is known from EP-A-0 401 466. It contains embossed diffraction structures 16 which are repeated several times in the foil strip 2.

Die Fig. 3 zeigt eine einzelne Sicherheitsmarke 7 mit einer Schicht aus dem Kleber 3, die aus dem Folienband 2 ausgestanzt ist. Die Bezugszahlen entsprechen denen der Fig. 2.3 shows a single security mark 7 with a layer of adhesive 3 which is punched out of the film strip 2. The reference numbers correspond to those in FIG. 2.

Das erfindungsgemƤƟe Verfahren zum Herstellen von Dokumenten mit Sicherheitsmarken 7 unter Verwendung eines durch ultraviolettes Licht oder durch Elektronenbestrahlung aktivierbaren Klebers 3 besteht darin, daƟ das die Sicherheitsmarken 7 beinhaltende Folienband 2 mit einem durch ultraviolettes Licht oder durch Elektronenbestrahlung aktivierbaren Kleber 3 beschichtet wird, wobei anschlieƟend der Kleber 3 durch ultraviolettes Licht oder Elektronenbestrahlung aktiviert wird, und daƟ aus dem Folienband 2 Sicherheitsmarken 7 ausgestanzt werden, die unmittelbar danach noch im Stanz- und Klebewerk 6 auf das Substrat 5 geklebt werden.The method according to the invention for producing documents with security tags 7 using an adhesive 3 that can be activated by ultraviolet light or by electron radiation consists in coating the film strip 2 containing the security tags 7 with an adhesive 3 that can be activated by ultraviolet light or by electron radiation, the subsequently Adhesive 3 is activated by ultraviolet light or electron radiation, and that 2 security marks 7 are punched out of the film strip, which are then immediately adhered to the substrate 5 in the punching and gluing unit 6.

Die Verwendung eines durch ultraviolettes Licht oder Elektronenbestrahlung aktivierbaren Klebers 3 anstelle eines HeiƟklebers hat den Vorteil, daƟ die Vorrichtung zum Stanzen und Aufkleben von Sicherheitsmarken sehr einfach ist, weil auf eine Heizeinrichtung verzichtet werden kann.The use of an adhesive 3 which can be activated by ultraviolet light or electron radiation instead of a hot adhesive has the advantage that the device for punching and sticking security tags is very simple because a heating device can be dispensed with.

Nachfolgend wird eine solche einfache Vorrichtung beschrieben.Such a simple device is described below.

Die Fig. 4 zeigt Einzelheiten des Stanz- und Klebewerks 6 in offener Stellung. An einer Stempelplatte 21 ist ein Stempel 22 befestigt. Eine Schnittwerkzeug-FĆ¼hrung 23 wird von FĆ¼hrungsstiften 24 gefĆ¼hrt und mittels Federn 25 gegen die Stempelplatte 21 abgestĆ¼tzt. An der Schnittwerkzeug-FĆ¼hrung 23 ist eine Matrize 26 befestigt. Die Schnittwerkzeug-FĆ¼hrung 23 und die Matrize 26 bilden zusammen ein Schnittwerkzeug 27. Auf einer Gegendruckplatte 28 liegt das Substrat 5. Zwischen dem Stempel 22 und der Matrize 26 wird das Folienband 2 hindurchgefĆ¼hrt.4 shows details of the punching and gluing unit 6 in the open position. A stamp 22 is attached to a stamp plate 21. A cutting tool guide 23 is guided by guide pins 24 and supported against the stamp plate 21 by means of springs 25. A die 26 is attached to the cutting tool guide 23. The cutting tool guide 23 and the die 26 together form a cutting tool 27. The substrate 5 lies on a counterpressure plate 28. The foil strip 2 is passed between the punch 22 and the die 26.

Das Folienband 2 und das Substrat 5 weisen nicht dargestellte Registermarken auf, die mittels ebenfalls nicht dargestellter Registermarkenleser erkannt werden und die genaue gegenseitige Positionierung von Folienband 2 und Substrat 5 in der Ć¼blichen Weise erlauben.The film strip 2 and the substrate 5 have register marks (not shown) which are recognized by means of register mark readers (also not shown) and the exact mutual positioning of the film strip 2 and substrate 5 in the usual manner Allow wise.

Wird die Stempelplatte 21 gegen die Gegendruckplatte 28 bewegt, so wird zunƤchst das Substrat 5 zwischen der Gegendruckplatte 28 und einer AuflageflƤche 29 der Matrize 26 festgeklemmt. Bei weiterer Bewegung der Stempelplatte 21 bewegt sich der Stempel 22 relativ zum Schnittwerkzeug 27 und dabei drĆ¼ckt eine StirnflƤche 30 des Stempels 22 das Folienband 2 gegen eine AbstĆ¼tzflƤche 31 der Matrize 26. AnschlieƟend taucht der Stempel 22 in eine Ɩffnung 32 der Matrize 26 ein, wobei im Moment des Eintauchens das Folienband 2 geschnitten wird. Dabei wird, was aus der Fig. 4 selbst nicht erkennbar ist, eine Sicherheitsmarke 7 aus dem Folienband 2 ausgeschnitten, die sich dann an der StirnflƤche 30 des Stempels 22 befindet. Der Stempel 22 bewegt sich nun weiter auf die Gegendruckplatte 28 zu, bis die StirnflƤche 30 des Stempels 22 mit der Sicherheitsmarke 7 auf das Substrat 5 aufsetzt. Im Moment des Aufsetzens wird die Sicherheitsmarke 7 auf das Substrat 5 geklebt. AnschlieƟend bewegen sich Schnittwerkzeug 27 und Stempel 22 wieder von der Gegendruckplatte 28 weg.If the stamp plate 21 is moved against the counter-pressure plate 28, the substrate 5 is first clamped between the counter-pressure plate 28 and a support surface 29 of the die 26. When the stamp plate 21 moves further, the stamp 22 moves relative to the cutting tool 27 and an end face 30 of the stamp 22 presses the film strip 2 against a support surface 31 of the die 26. The punch 22 then dips into an opening 32 of the die 26, whereby the film strip 2 is cut at the moment of immersion. 4, a security mark 7 is cut out of the film strip 2, which is then located on the end face 30 of the stamp 22. The stamp 22 now moves further towards the counter-pressure plate 28 until the end face 30 of the stamp 22 with the security mark 7 is placed on the substrate 5. At the moment of placement, the security mark 7 is glued to the substrate 5. The cutting tool 27 and the punch 22 then move away from the counterpressure plate 28 again.

Danach werden Folienband 2 und Substrat 5 durch nicht gezeigte Vorrichtungen weiterbewegt, so daƟ anschlieƟend der nƤchste Schneid- und Klebvorgang stattfinden kann.Thereafter, the film strip 2 and substrate 5 are moved on by means not shown, so that the next cutting and gluing process can then take place.

Um das Ankleben des mit dem Kleber 3 beschichteten Folienbands 2 auf der AbstĆ¼tzflƤche 31 der Matrize 26 zu verhindern, ist es vorteilhaft, wenn die AbstĆ¼tzflƤche 31 mit einem Antihaftmittel beschichtet ist. Sie kann teflonisiert oder silikonisiert sein. Beim Stanzen stĆ¼tzt sich das Folienband 2 mit seiner mit dem Kleber 3 beschichteten Seite auf dieser AbstĆ¼tzflƤche 31 ab.In order to prevent the film tape 2 coated with the adhesive 3 from sticking to the support surface 31 of the die 26, it is advantageous if the support surface 31 is coated with an anti-adhesive. It can be teflon-coated or siliconized. During punching, the film strip 2 is supported with its side coated with the adhesive 3 on this support surface 31.

Ein Stanz- und Klebewerk 6 gemƤƟ der Fig. 1 enthƤlt vorteilhaft mehrere der in Fig. 4 dargestellten Werkzeuge, so daƟ in einem Arbeitsgang mehrere Sicherheitsmarken 7 auf das Substrat 5 geklebt werden kƶnnen.A punching and gluing unit 6 according to FIG. 1 advantageously contains several of the tools shown in FIG. 4, so that several security marks 7 can be glued to the substrate 5 in one operation.

Das Folienband 2 kann auch als durchgehender Streifen auf das Substrat 5 geklebt werden. In diesem Fall kann auf das Stanzen ganz verzichtet werden.The film strip 2 can also be a continuous strip on the Substrate 5 are glued. In this case, punching can be dispensed with entirely.

Claims (3)

  1. A process for the production of documents which have a substrate (5) and at least one security mark (7) in which the security mark (7) is stamped or cut out of a foil strip (2) of a layer composite, provided with an adhesive (3) and stuck on to the substrate (5) at the side provided with the adhesive (3), characterised in that firstly an adhesive (3) which can be activated by UV- or electron beams is applied to the foil strip (2), thereafter the layer of the adhesive (3) is activated by direct irradiation with UV- or electron beams, then the security mark (7) which is provided with the activated adhesive (3) is stamped out of the foil strip (2) and pressed on to the substrate (5) and possibly the substrate (5) which is provided with the security mark (7) is again irradiated with UV- or electron beams for possibly hardening the adhesive (3).
  2. A process according to claim 1 characterised in that in the operation of stamping out the security marks (7) the foil strip (2) is supported with its side that is coated with the adhesive (3) on a die (26) which is coated with an anti-adhesion agent.
  3. Use of the process according to claim 1 or claim 2 for the production of documents in which the security marks have diffraction structures which are repeated in the foil strip (2).
