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 zum Herstellen von Dokumenten mit Sicherheitsmarken der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a method for producing documents with security marks of the type mentioned in the preamble of claim 1.

Ein solches Verfahren eignet sich beispielsweise zur Herstellung von besonders fälschungssicheren Banknoten, bei denen auf blattförmigen Druckerzeugnissen einzelne optisch auffällige Sicherheitsmarken angebracht werden.Such a method is suitable, for example, for the production of particularly counterfeit-proof banknotes, in which individual optically striking security marks are applied to sheet-like printed products.

Ein Verfahren der im Oberbegriff des Anspruchs 1 genannten Art ist aus der Druckschrift "SPIE Vol. 1210 Optical Security and Anticounterfeiting Systems" (1990), S. 14 - 19 bekannt. Hier wird bei der Herstellung von Banknoten ein durch UV-Licht aktivierbarer Kleber auf die Banknote mit einem Druckverfahren aufgebracht und dann durch UV-Bestrahlung voraktiviert. Danach wird eine beschichtete Folie, deren Schicht die Sicherheitsmarken enthält, auf das Kleberbild gepreßt und so verklebt. Anschließend wird die Trägerfolie abgezogen. Die Schicht reißt am Rand der Klebestelle ab und das transferierte Bild weist somit eine mangelhafte Randschärfe auf. Dies ist ästhetisch unbefriedigend und kann außerdem in Banknoten-Prüfgeräten zu Erkennungsproblemen führen.A method of the type mentioned in the preamble of claim 1 is known from the publication "SPIE Vol. 1210 Optical Security and Anticounterfeiting Systems" (1990), pp. 14-19. Here, in the production of bank notes, an adhesive that can be activated by UV light is applied to the bank note using a printing process and then preactivated by UV radiation. Then a coated film, the layer of which contains the security marks, is pressed onto the adhesive image and thus glued. The carrier film is then removed. The layer tears off at the edge of the glue point and the transferred image thus has poor edge sharpness. This is aesthetically unsatisfactory and can also lead to detection problems in banknote checking devices.

Bekannt ist außerdem (EP-A-0 401 466) ein Schichtverbund, aus dem Marken gestanzt werden können, die auffällige, optisch variable Kompositionen aus Beugungsstrukturen aufweisen. Der Schichtverbund umfaßt eine Heißkleberschicht, so daß zum Aufkleben die Anwendung von Wärme erforderlich ist.Also known (EP-A-0 401 466) is a layer composite from which stamps can be punched which have striking, optically variable compositions of diffraction structures. The composite layer comprises a hot-melt adhesive layer, so that the application of heat is necessary for the adhesive bonding.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, mit dem Sicherheitsmarken auf Dokumente appliziert werden können, bei dem auf die Anwendung von Wärme beim Aufkleben verzichtet werden kann und bei dem die Randschärfe des transferierten Bildes der Sicherheitsmarke groß ist.The invention has for its object to provide a method with which security marks can be applied to documents, in which the application of heat when gluing can be dispensed with and in which the edge sharpness of the transferred image of the security mark is large.

Die genannte Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 und 2 gelöst. Eine vorteilhafte Ausgestaltung ist im Anspruch 3 angegeben. Eine Vorrichtung zum Ausstanzen von Sicherheitsmarken gemäß dem Kennzeichen der Ansprüche 1 bis 3 ist im Anspruch 5 genannt.According to the invention, the stated object is achieved by the features of claims 1 and 2 solved. An advantageous embodiment is specified in claim 3. A device for punching out security tags according to the characterizing part of claims 1 to 3 is mentioned in claim 5.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

a tool for punching and gluing.

In der Fig. 1 bedeutet 1 ein Beschichtungswerk, mit dem ein Folienband 2 einseitig mit einem Kleber 3 beschichtet wird. Der Kleber 3 ist ein Kaltkleber, der im Ausgangszustand flüssig, aber nicht klebrig ist und der erst durch Bestrahlung mit einer ultraviolettes Licht aussendenden ersten UV-Quelle 4 klebrig wird. Mit 5 ist ein mit einer Sicherheitsmarke zu versehendes Substrat bezeichnet. Dieses Substrat 5 kann in Form von Bogen oder in Rollenform vorliegen. Dabei handelt es sich beispielsweise um Großbogen, die eine Anzahl von bereits gedruckten, aber noch nicht zerschnittenen Banknoten enthalten.In FIG. 1, 1 means a coating unit with which a film strip 2 is coated on one side with an 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. 5 denotes a substrate to be provided with a security mark. This substrate 5 can be in the form of sheets or in roll form. 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. An UV source 4 then takes the place of the UV source 4.

Der Kleber 3 kann auch ein Kleber sein, der eine Voraktivierung durch die UV-Quelle 4 oder die Elektronenstrahl-Quelle nicht benötigt. Solche Kleber sind im kalten Zustand zwar klebrig, haben jedoch im kalten Zustand eine zum Auftragen auf das Folienband 2 nicht geeignete Viskosität. Deshalb werden sie im heißen Zustand aufgetragen. Das Beschichtungswerk 1 enthält in diesem Fall eine Heizeinrichtung. Bei Verwendung des hier genannten Klebers 3 kann die Voraktivierung durch die UV-Quelle 4 bzw. die Elektronenstrahlquelle entfallen.The adhesive 3 can also be an adhesive that does not require preactivation by the UV source 4 or the electron beam source. Such adhesives are sticky in the cold state, but in the cold state they have an unsuitable viscosity for application to the film strip 2. That's why they are applied when hot. In this case, the coating unit 1 contains a heating device. When using the adhesive 3 mentioned here, the preactivation by the UV source 4 or the electron beam source can be omitted.

Das Folienband 2 ist ein Sicherheitsmarken enthaltendes Band, das später 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 zugeführt, 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 unit 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 zugeführt, in der das bogenförmige 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, daß der Kleber 3 vollständig aushärtet, so daß 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 cures 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 für das Folienband 2 dargestellt. Es besteht aus einer transparenten Trägerschicht 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 enthält eingeprägte 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 erfindungsgemäße Verfahren zum Herstellen von Dokumenten mit Sicherheitsmarken 7 unter Verwendung eines durch ultraviolettes Licht oder durch Elektronenbestrahlung aktivierbaren Klebers 3 besteht darin, daß das die Sicherheitsmarken 7 beinhaltende Folienband 2 mit einem durch ultraviolettes Licht oder durch Elektronenbestrahlung aktivierbaren Kleber 3 beschichtet wird, wobei anschließend der Kleber 3 durch ultraviolettes Licht oder Elektronenbestrahlung aktiviert wird, und daß 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 adhesive work 6.

Die Verwendung eines durch ultraviolettes Licht oder Elektronenbestrahlung aktivierbaren Klebers 3 anstelle eines Heißklebers hat den Vorteil, daß die Vorrichtung zum Stanzen und Aufkleben von Sicherheitsmarken sehr einfach sein kann, weil auf eine Heizeinrichtung verzichtet werden kann. Nachfolgend wird eine solche einfache Vorrichtung beschrieben.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 can be very simple because a heating device can be dispensed with. 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-Führung 23 wird von Führungsstiften 24 geführt und mittels Federn 25 gegen die Stempelplatte 21 abgestützt. An der Schnittwerkzeug-Führung 23 ist eine Matrize 26 befestigt. Die Schnittwerkzeug-Führung 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 hindurchgeführt.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 by means of springs 25 against the stamp plate 21. 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 counter-pressure 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 üblichen 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 zunächst das Substrat 5 zwischen der Gegendruckplatte 28 und einer Auflagefläche 29 der Matrize 26 festgeklemmt. Bei weiterer Bewegung der Stempelplatte 21 bewegt sich der Stempel 22 relativ zum Schnittwerkzeug 27 und dabei drückt eine Stirnfläche 30 des Stempels 22 das Folienband 2 gegen eine Abstützfläche 31 der Matrize 26. Anschließend taucht der Stempel 22 in eine Öffnung 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 Stirnfläche 30 des Stempels 22 befindet. Der Stempel 22 bewegt sich nun weiter auf die Gegendruckplatte 28 zu, bis die Stirnfläche 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. Anschließend 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 plunges 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 counterpressure 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 onto 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 daß anschließend der nächste 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 Abstützfläche 31 der Matrize 26 zu verhindern, ist es vorteilhaft, wenn die Abstützfläche 31 mit einem Antihaftmittel beschichtet ist. Sie kann teflonisiert oder silikonisiert sein. Beim Stanzen stützt sich das Folienband 2 mit seiner mit dem Kleber 3 beschichteten Seite auf dieser Abstützfläche 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 gemäß der Fig. 1 enthält vorteilhaft mehrere der in Fig. 4 dargestellten Werkzeuge, so daß in einem Arbeitsgang mehrere Sicherheitsmarken 7 auf das Substrat 5 geklebt werden können.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.

Es ist auch möglich, anstelle eines durch ultraviolettes Licht oder Elektronenbestrahlung aktivierbaren Klebers 3 einen gewöhnlichen Kaltkleber zu verwenden.It is also possible to use an ordinary cold adhesive instead of an adhesive 3 which can be activated by ultraviolet light or electron radiation.
