Abstract

Die Erfindung betrifft eine Druckeinheit (10) einer Rollendruckmaschine, mit mindestens einem Druckwerk (11, 12, 13, 14), wobei das oder jedes Druckwerk einen Formzylinder (15), einen Übertragungszylinder (16), ein Farbwerk sowie gegebenenfalls ein Feuchtwerk umfasst, wobei der Übertragungszylinder (16) des oder jedes Druckwerks auf einem demselben zugeordneten Satellitenzylinder (17) unter Ausbildung eines Druckspalts abrollt, wobei der oder jeder Satellitenzylinder (17) von ausschließlich einem auf demselben abrollenden Übertragungszylinder aus angetrieben ist, und wobei der Übertragungszylinder (16) des oder jedes Druckwerks translatorisch zwischen einer Druck-An-Position und einer Druck-Ab-Position verlagerbar ist, und mit einer Kompensationseinrichtung (19), mit Hilfe derer eine bei Verlagerung eines Übertragungszylinders (17) zwischen der Druck-An-Position und der Druck-Ab-Position bedingte Gefahr der Ausbildung von Rissen in einer Bedruckstoffbahn minimierbar ist. Erfindungsgemäß steuert die Kompensationseinrichtung (19) auf Grundlage mindestens eines vorab ermittelten Korrekturwerts einen Antrieb (18) zumindest des Übertragungszylinders (16), der bei seiner Verlagerung zwischen der Druck-An-Position und der Druck-Ab-Position eine Verdrehung des von demselben angetriebenen Satellitenzylinders (17) bewirkt, derart, dass der Antrieb (18) die durch die Verlagerung des Übertragungszylinders (16) bedingte Verdrehung des Satellitenzylinders (17) kompensiert.

The invention relates to a printing unit (10) of a web-fed printing press, comprising at least one printing unit (11, 12, 13, 14), wherein the or each printing unit comprises a forme cylinder (15), a transfer cylinder (16), an inking unit and optionally a dampening unit, wherein the transfer cylinder (16) of the or each printing unit unrolls on a satellite cylinder (17) associated therewith to form a printing nip, the or each satellite cylinder (17) being driven by only one transfer cylinder rolling on the same, and the transfer cylinder (16) the or each printing unit is translationally displaceable between a print-on position and a print-off position, and with a compensation device (19), by means of which one upon displacement of a transfer cylinder (17) between the print-on position and the Pressure-off position conditional risk of the formation of cracks in a printing material is minimized. According to the invention, the compensating device (19) controls, based on at least one previously determined correction value, a drive (18) at least of the transfer cylinder (16) which, when displaced between the pressure-on position and the pressure-off position, rotates the same driven by the same Satellite cylinder (17) causes such that the drive (18) compensates for the rotation of the satellite cylinder (17) due to the displacement of the transfer cylinder (16).
