ABSTRACT:
A printing unit is provided including a frame and at least a first printing group having a first plate cylinder and a first blanket cylinder which is intended to co-operate with a pressing cylinder. The printing group further includes a mechanism by means of which the first blanket cylinder can be moved between at least one throw-on position, in which it is pressed against the first plate cylinder and against the pressing cylinder, and a throw-off position, in which it is spaced apart from the first plate cylinder and the pressing cylinder. The support mechanism includes at least one main connection rod which can be moved relative to the frame and which carries the blanket cylinder. The main connection rod can be moved in rotation relative to the frame about the centre axis of the first plate cylinder.
