Abstract
Description
Die Erfindung betrifft einen Druckmaschinenzylinder nach dem Oberbegriff des Anspruchs 1.The invention relates to a printing machine cylinder according to the preamble of claim 1.
Druckwerke von Druckmaschinen 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. Mit den Übertragungszylindern wirken Gegendruckzylinder zusammen, wobei ein solcher Gegendruckzylinder bei einer Druckeinheit einer Rollendruckmaschine, die mehrere Druckwerke umfasst, entweder als Satellitenzylinder oder als Übertragungszylinder eines benachbarten Druckwerks ausgebildet sein kann. Neben Formzylindern, Überiragungszylindern und Gegendruckzylindern sind in einer Druckmaschine weitere Zylinder bzw. Walzen verbaut, so zum Beispiel Farbwerkwalzen, Feuchtwerkwalzen und bei Rollendruckmaschinen Bahnleitwalzen. Wenn nachfolgend der Begriff Druckmaschinenzylinder verwendet wird, sollen hierunter sowohl Zylinder als auch Walzen verstanden werden.Printing units of printing presses have, in addition to a forme cylinder, which serves to receive at least one printing form, furthermore via a transfer cylinder, which serves to receive a transfer form. Form cylinders are also referred to as a plate cylinder and transfer cylinder as a rubber cylinder. Counter-pressure cylinders cooperate with the transfer cylinders, such a counter-pressure cylinder, in the case of a printing unit of a web-fed printing press comprising a plurality of printing units, being designed either as a satellite cylinder or as a transfer cylinder of an adjacent printing unit. In addition to form cylinders, Überiragungszylindern and counter-pressure cylinders other cylinders or rollers are installed in a printing press, such as inking rollers, dampening rollers and web presses web guiding rollers. If the term printing press cylinder is used below, this is to be understood as meaning both cylinders and rolls.
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 Druckmaschinen bekannt, deren Druckmaschinenzylinder derart ausgelegt sind, dass sechs Druckseiten nebeneinander 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.In web presses, an increasing trend is to be seen in that increasingly wider webs are to be printed with an ever-increasing number of print pages positioned side by side. Thus, printing presses are already known from practice, the printing press cylinders are designed so that six pages can be printed side by side on a substrate. Printing press cylinders with such a large axial width are prone to deflection and to the formation of local temperature increases. This can negatively affect the print quality.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen neuartigen Druckmaschinenzylinder zu schaffen. Diese Aufgabe wird durch einen Druckmaschinenzylinder gemäß Anspruch 1 gelöst. Erfindungsgemäß ist der Zylindergrundkörper aus phenolharzgetränkten Textilfasern oder aus Hartpappe gebildet.On this basis, the present invention has the object to provide a novel printing press cylinder. This object is achieved by a printing machine cylinder according to claim 1. According to the invention, the cylinder base body is formed from phenolic-impregnated textile fibers or from hardboard.
Im Sinne der hier vorliegenden Erfindung wird ein Druckmaschinenzylinder vorgeschlagen, dessen Zylindergrundkörper aus phenolharzgetränkten Textilfasern oder aus Hartpappe gebildet ist. Phenolharzgetränkte Textilfasern sowie Hartpappe verleihen dem Druckmaschinenzylinder eine hohe Formstabilität, gewährleisten jedoch eine deutliche Gewichtsreduzierung, so dass die Gefahr einer Durchbiegung des Druckmaschinenzylinders deutlich verringert wird. Hierdurch wird auch die Gefahr der Ausbildung lokaler Temperaturerhöhungen verringert. Ein Zylindergrundkörper aus phenolharzgetränkten Textilfasern oder aus Hartpappe ist weitestgehend korrosionsbeständig. Auf spezielle Korrosionsbeschichtungen kann daher verzichtet werden, Ein weiterer Vorteil eines Zylindergrundkörpers aus phenolharzgetränkten Textilfasern oder Hartpappe besteht darin, dass dieser im Vergleich zu einem Zylindergrundkörper, der aus glasfaserverstärktem Kunststoff oder kohlefaserverstärktem Kunststoff gebildet ist, deutlich kostengünstiger ist.For the purposes of the present invention, a printing press cylinder is proposed, the cylinder base body is formed of phenol resin impregnated textile fibers or hardboard. Phenol resin impregnated textile fibers and hardboard give the printing press cylinder a high dimensional stability, but ensure a significant reduction in weight, so that the risk of deflection of the printing press cylinder is significantly reduced. This also reduces the risk of the formation of local temperature increases. A cylinder base made of phenol resin impregnated textile fibers or hardboard is largely resistant to corrosion. It is therefore possible to dispense with special corrosion coatings. Another advantage of a cylinder base made of textile fibers or cardboard impregnated with phenolic resin is that it is considerably less expensive than a cylinder base body formed from glass fiber reinforced plastic or carbon fiber reinforced plastic.
Nach einer vorteilhaften Weiterbildung der Erfindung ist zwischen dem Zylindergrundkörper aus phenolharzgetränkten Textilfasern oder aus Hartpappe und der Funktionsschicht eine Schutzschicht angeordnet.According to an advantageous embodiment of the invention, a protective layer is disposed between the cylinder base made of phenol resin impregnated textile fibers or hard cardboard and the functional layer.
