Abstract

In a method and a device for attaching a thin flexible printing plate on a plate cylinder of a web-fed rotary printing machine, an adhesive, e.g. a glue for detachable bondings, is applied between the rear side of the printing plate and the outer surface of the plate cylinder. The printing plate is then applied so as to be in register and placed without creasing on the plate cylinder. Due to the adhesive, the printing plate adheres firmly to the body of the plate cylinder or a non-detachable base provided on the plate cylinder and is mounted virtually securely against displacement, in particular against transverse forces.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Durchführung des Verfahrens zum Befestigen einer flexiblen, dünnen Druckplatte auf einem Plattenzylinder einer Rotationsdruckmaschine.The invention relates to a method and a device for carrying out the method for fastening a flexible, thin printing plate on a plate cylinder of a rotary printing press.

Insbesondere dünne Druckplatten weisen nur eine geringe Eigensteifigkeit auf, so daß sie auf dem Plattenzylinder durch auf sie einwirkende Kräfte verschiebbar, insbesondere seitlich verschiebbar sind.Thin printing plates in particular have only a low intrinsic stiffness, so that they can be displaced, in particular laterally, on the plate cylinder by forces acting on them.

Eine Verschiebung der Druckplatte, besonders auch eine seitliche Verschiebung, kann Registerfehler erzeugen und dadurch eine Qualitätsminderung hervorrufen. Im schlimmsten Fall kann die Folge eine Beschädigung der Druckplatte sein.A shift of the printing plate, especially a lateral shift, can cause register errors and thus cause a reduction in quality. In the worst case, the pressure plate can be damaged.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Durchführung des Verfahrens zum Befestigen einer flexiblen, dünnen Druckplatte auf einem Plattenzylinder einer Rotationtsdruckmaschine zu schaffen, das es ermöglicht, daß von der Druckplatte Querkräfte aufgenommen werden können und welches zuläßt, daß die Druckplatte schnell und zerstörungsfrei vom Plattenzylinder lösbar ist.The invention has for its object to provide a method and an apparatus for performing the method for fastening a flexible, thin printing plate on a plate cylinder of a rotary printing press, which enables transverse forces to be absorbed by the printing plate and which allows the printing plate can be detached from the plate cylinder quickly and non-destructively.

Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Teile der Ansprüche 1 und 7 bis 10 gelöst.The object is achieved by the characterizing Parts of claims 1 and 7 to 10 solved.

Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung haben eine ganze Reihe von Vorteilen. Selbst bei der Verwendung herkömmlicher Druckplattenklemmeinrichtungen liegt die flexible, dünne Druckplatte fest und unverschiebbar auf dem Plattenzylinder auf. Hierdurch entstehen nahezu verzerrungsfreie Abbildungen hoher Qualität auf dem Druckträger.The method and the device according to the invention have a number of advantages. Even when using conventional printing plate clamping devices, the flexible, thin printing plate rests firmly and immovably on the plate cylinder. This creates almost distortion-free images of high quality on the print carrier.

In vorteilhafter Weise ermöglicht das neue Verfahren die Einsparung konventioneller Druckplattenspanneinrichtungen und u. U. auch die Einsparung der Druckplattenklemmeinrichtung,so daß nur Einrichtungen zum registergerechten Aufbringen der Druckplatte erforderlich sind. Registereinrichtungen können einfachster Bauart sein, angefangen von sehr schmalen Registerschlitzen, in die ein Druckplattenanfang eingehängt wird, bis hin zu einfachen Markierungen auf der Plattenzylindermantelfläche, die mit der dünnen, flexiblen Druckplatte in Übereinstimmung gebracht werden.The new method advantageously makes it possible to save conventional printing plate clamping devices and u. U. also the saving of the printing plate clamping device, so that only devices for register-correct application of the printing plate are required. Register devices can be of the simplest type, starting from very narrow register slots, into which a printing plate start is hung, to simple markings on the surface of the plate cylinder, which are brought into line with the thin, flexible printing plate.

Derart einfach ausgeführte Plattenzylinder sind äußerst kostengünstig herstellbar und ermöglichen zugleich einen Druck mit sehr schmalen Rädern. Obgleich die dünnen, flexiblen Druckplatten verschiebfest auf dem Plattenzylinder haften, sind sie leicht zerstörungsfrei vom Plattenzylinder lösbar und somit wiederverwendbar.Plate cylinders of such a simple design can be produced very inexpensively and at the same time enable printing with very narrow wheels. Although the thin, flexible printing plates adhere to the plate cylinder so that they cannot move, they can be easily removed from the plate cylinder without destruction and are therefore reusable.

Die beim erfindungsgemäßen Verfahren verwendeten Druckplatten sind dünne, flexible Kunststoffdruckplatten (0,1 - 0,5 mm) z. B. aus Polyesther oder Metallfolien. Diese sowohl für den direkten und indirekten Hochdruck als auch Offset- / Flachdruck geeigneten Druckplatten werden auf ihrer Rückseite mit einer Schicht eines Klebers für lösbare Verbindungen versehen. Auf dem Markt sind zur Zeit z. B. folgende derartige Kleber erhältlich, Scotch 3M "Sprühkleber", Anchorit "Sprühkleber" oder Eggen " Montagekleber".The printing plates used in the method according to the invention are thin, flexible plastic printing plates (0.1-0.5 mm) z. B. from polyester or metal foils. This for both direct and indirect high pressure as well as offset / planographic printing plates are provided on the back with a layer of adhesive for detachable connections. There are currently z. B. the following such adhesives available, Scotch 3M "spray adhesive", Anchorit "spray adhesive" or harrows "assembly adhesive".

Selbstverständlich ist es auch möglich, den Kleber auf die Plattenzylindermantelfläche aufzubringen oder auf beide Flächen, also sowohl auf die Rückseite der Druckplatte als auch auf die Plattenzylindermantelfläche.
Erfahrungsgemäß ist jedoch der Kleberauftrag auf eine Seite ausreichend.
Of course, it is also possible to apply the adhesive to the plate cylinder jacket surface or to both surfaces, that is to say both to the back of the printing plate and to the plate cylinder jacket surface.
Experience has shown, however, that glue application on one side is sufficient.

Als nächstes wird die Druckplatte mit ihrer vorlaufenden Vorderkante an den Plattenzylinder angelegt und an Registermarken ausgerichtet. Danach wird die Druckplatte faltenfrei auf die Oberfläche des Plattenzylinders aufgelegt. Dies erfolgt durch Glattstreichen der Druckplatte mit der Hand oder einem anderen Mittel, z. B. auch durch den Anpreßdruck eines mit dem Plattenzylinder zusammenwirkenden anderen Zylinders (Gummizylinder, Gegendruckzylinder, Andrückrolle etc.).Next, the leading edge of the printing plate is placed against the plate cylinder and aligned with register marks. The printing plate is then placed wrinkle-free on the surface of the plate cylinder. This is done by smoothing the pressure plate by hand or another means, e.g. B. also by the contact pressure of another cylinder interacting with the plate cylinder (rubber cylinder, impression cylinder, pressure roller etc.).

Nach Durchführung des erfindungsgemäßen Verfahrens haftet die Druckplatte fest auf der Plattenzylindermantelfläche. Ein Reibwert (z. B. µ > 50) zwischen Druckplatte und Plattenzylindermantelfläche bewirkt eine formschlüssige Anhaftung der Druckplatte am Plattenzylinder und verhindert, daß sich die Druckplatte auf der Plattenzylindermantelfläche verschieben kann. In manchen Fällen kann die Plattenzylindermantelfläche mit einer flexiblen Unterlage unlösbar beklebt sein. Diese besteht meist aus einem feinporigem Schaumstoff (Microzellen). Unter den genannten Umständen wird die dünne, flexible Druckplatte dann mittels des Klebers auf der Unterlage lösbar befestigt. Zum Lösen der Druckplatte vom Plattenzylinder wird diese zunächst an ihrer Vorder- oder Hinterkante vom Zylinder abgehoben (z. B. per Hand) und wird dann von dem jeweiligen ersten Abhebepunkt ausgehend fortlaufend weiter abgehoben.After carrying out the method according to the invention, the printing plate adheres firmly to the surface of the plate cylinder. A coefficient of friction (eg µ> 50) between the pressure plate and the plate cylinder jacket surface causes the pressure plate to adhere positively to the plate cylinder and prevents the pressure plate from shifting on the plate cylinder jacket surface. In some In some cases, the surface of the plate cylinder can be permanently covered with a flexible underlay. This usually consists of a fine-pored foam (micro cells). Under the circumstances mentioned, the thin, flexible printing plate is then releasably attached to the base by means of the adhesive. To release the printing plate from the plate cylinder, it is first lifted from the cylinder at its front or rear edge (e.g. by hand) and is then raised continuously from the respective first lifting point.

Nach einer ersten erfindungsgemäßen Ausführung der Vorrichtung zum Befestigen der dünnen, flexiblen Druckplatte auf dem Plattenzylinder, weist der Plattenzylinder eine achsparallele, flache, V-förmige Grube auf. In den geneigten Seitenwänden sind Registerstifte vorgesehen, über welche ein Anfang der Druckplatte jeweils registerhaltig eingehängt wird. Ein Druckplattenende liegt unbefestigt auf der Plattenzylindermantelfläche auf. Die V-förmige Grube für die Aufnahme der Registereinrichtung ist für beide Drehrichtungen geeignet. Bei Änderung der Plattenzylinderdrehrichtung wird die Druckplatte gelöst und mit ihrem Druckanfang über die Registerstifte der jeweils anderen Seitenwand der V-förmigen Grube eingehängt.According to a first embodiment of the device according to the invention for fastening the thin, flexible printing plate on the plate cylinder, the plate cylinder has an axially parallel, flat, V-shaped pit. Register pins are provided in the inclined side walls, via which a beginning of the printing plate is hung in register. One end of the pressure plate lies unsecured on the surface of the plate cylinder. The V-shaped pit for receiving the register device is suitable for both directions of rotation. If the direction of rotation of the plate cylinder is changed, the pressure plate is released and its start of pressure is attached to the register pins on the other side wall of the V-shaped pit.

Es ist selbstverständlich auch möglich zur Durchführung des erfindungsgemäßen Verfahrens konventionelle Druckplattenklemmeinrichtungen zu benutzen.It is of course also possible to use conventional printing plate clamping devices to carry out the method according to the invention.

In einer weiteren erfindungsgemäßen Ausführung ist zur Registerung der Druckplatte ein zylinderlanger, achsparalleler Schlitz vorgesehen, in den ein registerhaltig abgekanteter Druckplattenanfang eingehängt wird. Je nach Ausführungsform wird auch das abgekantete Druckplattenende in den Schlitz eingehängt oder bleibt unabgekantet auf der Plattenzylindermantelfläche durch die Haftkraft des Klebers liegen. Diese Ausführung ist ebenfalls für eine Drehrichtungsumkehr des Platenzylinders geeignet.
Bei hohen Fliehkräften wird für die v-förmige Grube und den Schlitz ein Einsatzstück vorgesehen, welches auch gleichzeitig die Grube bzw. den Schlitz verschließt.
In a further embodiment according to the invention, a cylinder-long, Axially parallel slot is provided, in which a pressure plate beginning which is bent in register is hung. Depending on the embodiment, the bent printing plate end is also hooked into the slot or remains un-folded on the surface of the plate cylinder due to the adhesive force of the adhesive. This version is also suitable for reversing the direction of rotation of the plate cylinder.
In the case of high centrifugal forces, an insert is provided for the v-shaped pit and the slot, which also closes the pit or slot at the same time.

Bei einer dritten Ausführung kann auf eine Vertiefung im Plattenzylinder vollkommen verzichtet werden. Der Plattenzylinder weist nunmehr eine ringsherum geschlossene Mantelfläche auf. Die dünne, flexible Druckplatte liegt nun nur noch mittels der Haftkraft des Klebers für lösbare Verbindungen auf der Plattenzylindermantelfläche auf. Dieser weist allerdings Markierungen auf, die zum registergerechten Aufbringen der Druckplatte erforderlich sind. Die Registermarken werden nur noch in Deckung gebracht mit entsprechenden Markierungen auf der Druckplatte. Bei durchsichtigen Kunststoffplatten können diese Registermarkierungen z. B. auf die Druckplatte aufgemalt oder -gedruckt sein.
Bei Metallfolien können die Registermarken z. B. ausgestanzt sein, so daß sie mit den entsprechenden Registermarken auf dem Plattenzylinder in Deckung bringbar sind.
In a third embodiment, there is no need for a depression in the plate cylinder. The plate cylinder now has an all-round closed surface. The thin, flexible pressure plate now only lies on the surface of the plate cylinder by the adhesive force of the adhesive for detachable connections. However, this has markings that are required for the correct application of the printing plate. The register marks are only brought into line with corresponding markings on the printing plate. In the case of transparent plastic plates, these register markings can, for. B. painted or printed on the printing plate.
In the case of metal foils, the register marks can e.g. B. be punched out so that they can be brought into register with the corresponding register marks on the plate cylinder.

Die Erfindung ist nicht allein auf dünne, flexible Druckplatten anwendbar, sondern darüberhinaus auf alle anderen möglichen lösbaren Verbindungen zwischen Zylindern und deren Aufzügen.
Das Prinzip der Erfindung besteht also darin, daß zwischen der Trägerfläche eines Zylinders und einer Rückseite einer dünnen, flexiblen Druckplatte oder eines anderen dünnen, flexiblen Aufzuges ein Haftmittel aufgebracht wird, welches eine lösbare Verbindung beider Körper herstellt. Im Fall, daß der Zylinder eine Beschichtung oder eine andere nicht lösbare Unterlage aufweist, wird die lösbare Verbindung der Druckplatte bzw. der Unterlage mit der Zylinderbeschichtung bzw. der darauf nicht lösbar angebrachten Unterlage hergestellt. Das Haftmittel ist nicht allein auf die angegebenen Kleber beschränkt. Es ist darüberhinaus auch denkbar die Haftung z. B. mittels elektrostatischer Aufladung zu erzeugen.
The invention is not only applicable to thin, flexible printing plates, but also to all of them other possible detachable connections between cylinders and their elevators.
The principle of the invention is therefore that an adhesive is applied between the support surface of a cylinder and the back of a thin, flexible printing plate or other thin, flexible elevator, which creates a releasable connection between the two bodies. In the event that the cylinder has a coating or another non-releasable base, the releasable connection of the pressure plate or the base with the cylinder coating or the non-releasably attached base is made. The adhesive is not limited to the specified glue alone. It is also conceivable liability z. B. by means of electrostatic charging.
