Abstract
A printing unit ( ) for a printing machine, having an image cylinder ( ), an image generating device ( ) for setting an image on the peripheral surface ( ) of the image cylinder ( ), and an image transfer cylinder ( ) which transfers the image from the image cylinder ( ) to a printing substrate ( ), the image transfer cylinder ( ) having a resilient cover ( ) which exhibits a deformation ( ′) in the force transmission areas ( ), and a transport belt ( ) that carries the printing substrates ( ) and is supported by a back-pressure cylinder ( ) driving the image transfer cylinder ( ) and the latter driving the image cylinder ( ), by friction. The printing unit has a continuous image cylinder speed (v ). This is achieved by the back-pressure cylinder ( ) being mounted such that it can be displaced with respect to the image transfer cylinder ( ) with a travel-dependent pressing force (F ) which is dimensioned such that the speed of the image cylinder ( ) remains constant with respect to changes in the effective radius (r) for driving the image transfer cylinder ( ).
