Abstract

This new plate (1) is used on the cylinder of a rotary printing machine. On the side (7) facing the cylinder there is a novel, electrically-insulating layer (8). Preferably this layer is a polyfluoroethylenepropylene- (FEP) based plastic, or ceramic. The plate is a printing plate. The plate may be constructed as a carrier for an offset-printing, rubber cover.

Description

Die Erfindung betrifft eine Platte für einen Zylinder einer Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a plate for one Cylinder of a rotary printing press according to the Preamble of claim 1.

Aus der DE 43 15 311 A1 ist eine Druckplatte bekannt, deren Unterseite mit einem Gleitwerkstoff beschichtet ist.A printing plate is known from DE 43 15 311 A1, the underside of which is coated with a sliding material is.

Die DE 26 49 011 A1 beschreibt eine Druckplatte auf deren Rückseite eine Schicht aufgetragen ist, die gegenüber einem Material einer Oberfläche eines Zylinders nach der elektrochemischen Spannungsreihe der Metalle unedler ist.DE 26 49 011 A1 describes a printing plate the back of which is applied a layer that against a material of a surface of a Cylinders according to the electrochemical voltage series of the Metals is less noble.

Nachteilig ist hierbei, daß die Schicht auf der Rückseite der Druckplatte durch Reinigungsmittel zerstört wird.The disadvantage here is that the layer on the Back of the printing plate with detergent gets destroyed.

Der Erfindung liegt die Aufgabe zugrunde, eine Platte aus metallischem Werkstoff für einen Zylinder einer Rotationsdruckmaschine zu schaffen.The invention has for its object a plate made of metallic material for a cylinder one To create rotary printing press.

Diese Aufgabe wird erfindungsgemäß durch eine Platte mit den Merkmalen des kennzeichnenden Teiles des Anspruches 1 gelöst. This object is achieved by a plate with the characteristics of the characteristic part of the Claim 1 solved.  

In vorteilhafter Weise wird durch die erfindungsgemäße Platte eine Entstehung eines elektrochemischen Elementes zwischen Zylinder und darauf befestigter, elektrisch Isolierter Platte unter Einwirkung eines Elektrolytes vermieden. Dadurch wird Korrosion sowohl der Platte als auch des Zylinders verhindert. Der Elektrolyt kann bei einer Rotationsdruckmaschine aus Reinigungsmittel, Feuchtmittel oder Druckfarbe bestehen, der zwischen Platte und Zylinder penetriert.Advantageously, the inventive Plate an emergence of an electrochemical element between cylinder and attached, electrical Insulated plate under the influence of an electrolyte avoided. This will prevent both plate and corrosion also prevented the cylinder. The electrolyte can a rotary printing press made of detergent, Fountain solution or ink exist between Plate and cylinder penetrated.

Auf Folien zwischen Platte und Zylinder kann verzichtet werden. Dies vereinfacht die Handhabung beim Auflegen von Platten und die Sicherheit während des Betriebes, da keine Folien verrutschen können. Die Isolationsschicht der Platte ist wesentlich dünner als die bisher üblichen Folien, wodurch eine größere Formgenauigkeit der auf dem Zylinder montierten Platte und eine bessere Wärmeableitung über den Zylinder erreicht wird. Dadurch wird die Druckqualität erhöht.There is no need for foils between the plate and the cylinder will. This simplifies handling when hanging up of panels and safety during operation because no foils can slip. The insulation layer the plate is much thinner than usual Foils, which ensures greater dimensional accuracy of the on the Cylinder-mounted plate and better Heat dissipation is achieved via the cylinder. Thereby the print quality is increased.

Die erfindungsgemäße Platte ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The plate according to the invention is in the drawing shown and is described in more detail below.

Eine biegbare Platte 1 ist als Druckplatte oder als Trägerplatte für ein Gummituch 2 vorgesehen. Die Platte 2 besteht aus einem Metall, vorzugsweise Stahl oder Aluminium bzw. derer Legierungen. In einem in der Zeichnung dargestellten Ausführungsbeispiel ist die Platte 2 mit abgekanteten Enden 3, 4, die zur Aufnahme der Platte 2 auf einen Zylinder, z. B. Gummizylinder, einer Rotationsdruckmaschine dienen, versehen. Der Zylinder besteht ebenfalls aus Metall und kann beispielsweise mit einer aus Chrom oder Nickel bestehenden Schutzschicht beschichtet sein. Eine nach außen weisende Fläche 6 der Platte 1 ist mit einem Gummituch 2 beschichtet. Dieses Gummituch 2 kann beispielsweise auf die Platte 1 aufgeklebt oder aufvulkanisiert sein. Eine nach innen weisende, auf einer Mantelfläche des Zylinders aufliegenden Fläche 7 der Platte 1 ist mit einer dünnen Schicht 8 mit einer Dicke von ca. 0,01 mm bis 0,1 mm beschichtet. Diese Schicht 8 besteht aus einem nicht leitenden, d. h. elektrisch isolierenden Material und kann aufgespritzt, aufgestrichen oder elektrostatisch aufgebracht sein und mittels thermischer Verfahren fixiert sein. Als Material für eine derartige Beschichtung eignet sich beispielsweise ein Kunststoff auf Basis von Polyfluorethylenpropylen, Kautschuk oder Keramik.A bendable plate 1 is provided as a pressure plate or as a carrier plate for a rubber blanket 2 . The plate 2 consists of a metal, preferably steel or aluminum or their alloys. In one embodiment shown in the drawing, the plate 2 with beveled ends 3 , 4 , which for receiving the plate 2 on a cylinder, for. B. blanket cylinders, a rotary printing press are provided. The cylinder is also made of metal and can be coated, for example, with a protective layer made of chrome or nickel. An outwardly facing surface 6 of the plate 1 is coated with a rubber blanket 2 . This rubber blanket 2 can, for example, be glued or vulcanized onto the plate 1 . An inward-facing surface 7 of the plate 1 resting on a lateral surface of the cylinder is coated with a thin layer 8 with a thickness of approximately 0.01 mm to 0.1 mm. This layer 8 consists of a non-conductive, ie electrically insulating material and can be sprayed on, brushed on or applied electrostatically and fixed by means of thermal processes. A suitable material for such a coating is, for example, a plastic based on polyfluoroethylene propylene, rubber or ceramic.

Somit ist die auf dem Zylinder befestigte Platte 1 elektrisch isoliert zum Zylinder angeordnet.Thus, the plate 1 attached to the cylinder is arranged electrically insulated from the cylinder.
