Abstract
A printing group of a printing machine is comprised of a pair of cylinders each having a circumference that corresponds essentially to a length of a section of a side to be printed. The effective generated surface of at least one of the cylinders comprises, at the most, one break in the circumferential direction. The surface forms, in the longitudinal direction, a plurality of adjacently arranged breaks which, when viewed in the circumferential direction, are arranged in a staggered manner with respect to each other.
Claims48
A printing group of a printing press comprising:
- at least three cooperating cylinders defining said printing group each of said cylinders having spaced end faces;
- at least one lateral frame of said printing press, said at least one lateral frame being adapted to support at least one of said three cooperating cylinders;
- a lateral inner frame side of said at least one lateral frame, said lateral inner frame side facing adjacent ones of said end faces of said at least three cooperating cylinders;
- a journal on at least one of said end faces of said at least one of said three cooperating cylinders and located adjacent said lateral inner frame side;
- a bearing housing and including a radial bearing, said radial bearing being adapted to receive said journal;
- at least one linear guide device connected to said at least one lateral frame, said bearing housing being movably arranged in said linear guide device for linear movement of said at least one of said three cooperating cylinders, as a linearly movable cylinder, along a linear actuating path between a print-on position and a print-off position with respect to other ones of said at least three cooperating cylinders, said radial bearing being arranged in said bearing housing spaced laterally offset with respect to said lateral frame and said lateral inner frame side of said lateral frame facing said cylinders;
- and
- a drive motor for said linearly movable cylinder and supported by said linearly movable cylinder for movement with said linearly movable cylinder.
