Abstract

The cylinder has a cylinder base body made of fiber-reinforced plastic e.g. epoxy resin and polyurethane. The cylinder base body is coated with a wear-protection layer in an area of a lateral surface and an area of a clamping channel, by thermal spraying, chemical separation, galvanic separation or physical vapor deposition coating. The fibers of the fiber-reinforced plastic are carbon fibers, glass fibers or aramide fibers. The wear-protection layer comprises nickel and chrome.

Description

Die Erfindung betrifft einen Druckmaschinenzylinder nach dem Oberbegriff des Anspruchs 1.The The invention relates to a printing press cylinder according to the preamble of claim 1.

Druckwerke von Druckmaschinen, so z. B. von Rollendruckmaschinen, verfügen neben einem Formzylinder, welcher der Aufnahme mindestens einer Druckform dient, weiterhin über einen Übertragungszylinder, welcher der Aufnahme einer Übertragungsform dient. Formzylinder werden auch als Plattenzylinder und Übertragungszylinder auch als Gummizylinder bezeichnet.printing units of printing machines, such. B. of web presses, have next to a forme cylinder which receives at least one printing form serves, continues over a transfer cylinder, which is the recording of a transmission form serves. Form cylinders are also called plate cylinders and transfer cylinders Also referred to as rubber cylinder.

Bei Rollendruckmaschinen ist ein zunehmender Trend dahingehend zu erkennen, dass immer breitere Papierbahnen mit einer immer höheren Anzahl von nebeneinander positionierten Druckseiten bedruckt werden sollen. So sind bereits aus der Praxis Druckwerke bekannt, deren Druckmaschinenzylinder derart ausgelegt sind, dass sechs Druckseiten nebeneinander sowie eine oder zwei Druckseiten hintereinander je Umdrehung der Druckmaschinenzylinder auf einen Bedruckstoff gedruckt werden können. Druckmaschinenzylinder mit einer derart großen axialen Breite neigen zu einer Durchbiegung sowie zur Ausbildung lokaler Temperaturerhöhungen. Dies kann die Druckqualität negativ beeinflussen.at Web presses is an increasing trend to recognize that ever wider paper webs with an ever-increasing number to be printed by juxtaposed printed pages. So are already known from practice printing units whose printing press cylinder are designed so that six printed pages next to each other as well one or two pages in a row per revolution of the press cylinder can be printed on a substrate. Printing press cylinder with such a large axial Width tend to bend as well as to train local Temperature increases. This can be the print quality influence negatively.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen neuartigen Druckmaschinenzylinder zu schaffen.Of these, The present invention is based on the object, to create a novel printing press cylinder.

Diese Aufgabe wird durch einen Druckmaschinenzylinder gemäß Anspruch 1 gelöst. Der erfindungsgemäße Druckmaschinenzylinder weist einen Zylindergrundkörper aus faserverstärktem Kunststoff auf.These Task is by a printing press cylinder according to claim 1 solved. The printing press cylinder according to the invention has a cylinder main body made of fiber-reinforced Plastic on.

Mit der hier vorliegenden Erfindung wird erstmals vorgeschlagen, den Zylindergrundkörper eines Druckmaschinenzylinders aus faserverstärktem Kunststoff herzustellen. Hierdurch kann das Gewicht von Druckmaschinenzylindern deutlich reduziert werden, so dass selbst bei Druckmaschinenzylindern mit einer großen axialen Breite nicht die Gefahr einer unzulässigen Durchbiegung des Druckmaschinenzylinders sowie einer unzulässigen lokalen Temperaturerhöhung besteht. Ein weiterer Vorteil der Erfindung besteht darin, dass Zylindergrundkörper aus faserverstärktem Kunststoff weniger anfällig gegenüber einem Verschleiß durch Korrosion sind.With the present invention is proposed for the first time, the Cylinder body manufacture a printing press cylinder made of fiber-reinforced plastic. As a result, the weight of printing press cylinders clearly be reduced so that even with printing press cylinders with a huge axial width is not the risk of undue deflection of the printing press cylinder as well as an inadmissible local temperature increase consists. Another advantage of the invention is that Cylinder body made of fiber-reinforced Plastic less vulnerable across from due to wear Corrosion are.

Nach einer vorteilhaften Weiterbildung der Erfindung ist der Zylindergrundkörper aus faserverstärktem Kunststoff im Bereich einer Mantelfläche und/oder im Bereich eines Spannkanals mit einer Verschleißschutzschicht beschichtet.To an advantageous embodiment of the invention, the cylinder body is made fiber reinforced Plastic in the region of a lateral surface and / or in the region of a Clamping channel with a wear protection layer coated.

Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung.preferred Further developments of the invention will become apparent from the dependent claims and the following description.

Die hier vorliegende Erfindung betrifft einen Druckmaschinenzylinder einer Druckmaschine, insbesondere einer Rollendruckmaschine. Bei dem Druckmaschinenzylinder kann es sich um einen Formzylinder, Übertragungszylinder oder auch um einen Satellitenzylinder handeln. Im Satellitendruckprinzip ist ein gemeinsamer Gegendruckzylinder vorgesehen, dem mehrere Druckwerke satellitenartig zugeordnet sind. Dieser sogenannte Satellitenzylinder stellt damit gewissermaßen die „Sonne" des Satellitensystems dar.The The present invention relates to a printing press cylinder a printing machine, in particular a web-fed printing press. at the printing press cylinder can be a form cylinder, transfer cylinder or act around a satellite cylinder. In the satellite pressure principle a common impression cylinder is provided, the several printing units associated satellite. This so-called satellite cylinder puts it in a way the "sun" of the satellite system represents.

Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, dass ein Zylindergrundkörper des Drückmaschinenzylinders aus faserverstärktem Kunststoff gebildet ist.
