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.
Claims53
A printing group of a printing press comprising:
- at least one lateral frame:
- a first forme cylinder in said printing group;
- a first transfer cylinder cooperating with said first forme cylinder;
- a second forme cylinder in said printing group;
- a second transfer cylinder cooperating with said second forme cylinder, said first and second transfer cylinders forming a printing position when said cylinders are in a print-on position;
- each of said cylinders having an axis of rotation, said axes of rotation being located in a common plane in said print-on position;
- means supporting said first and second transfer cylinders for movement into and out of said print-on position, said common plane of said axes of rotation extending at an angle of 75° to 85° with respect to a plane of a web passing through said printing group;
- and
- at least one linear guide connected to said at least one lateral frame of said printing press, said at least one linear guide supporting at least one of said first and second transfer cylinders, said at least one linear guide being arranged on a lateral side of said at least one lateral frame facing each of said cylinders.
A printing group of a printing press comprising:
- at least one lateral frame in said printing press;
- at least three cylinders in said printing group and cooperating to define a printing position;
- means supporting at least one of said at least three cylinders for movement along a linear actuating path between a print-on position and a print-off position;
- a bearing housing supporting an end faces of said at least one cylinder supported for movement;
- and
- at least one linear guide connected to said lateral frame of said printing press, said at least one linear guide supporting said bearing housing, said at least one linear guide being arranged on a lateral side of said lateral frame facing said at least three cylinders.
A printing group of a printing press comprising:
- at least one lateral frame of said printing press;
- at least three cylinders in said printing group and cooperating to define a printing position;
- means supporting at least one of said at least three cylinders for movement along a linear actuating path between a print-on position and a print-off position;
- a bearing housing supporting an end face of said at least one cylinder supported for movement;
- at least two linear guides connected to said lateral frame of said printing press, said at least two linear guides supporting said bearing housing, said at least two linear guides being arranged spaced apart from each other and extending from a lateral side of said lateral frame facing said cylinders;
- and
- a bearing housing part and a fixed frame part in each said linear guide, said bearing housing part and said fixed frame part engaging each other.
A printing group of a printing press comprising:
- at least one lateral frame in said printing press;
- at least three cylinders in said printing group and cooperating to define a printing position;
- means supporting at least one of said at least three cylinders for movement along a linear actuating path between a print-on position and a print-off position;
- a bearing housing supporting an end face of said at least one cylinder supported for movement;
- an insert in said at least one lateral frame;
- and
- at least one linear guide connected to said insert in said lateral frame of said printing press, said at least one linear guide supporting said bearing housing, said at least one linear guide being arranged on a lateral side of said insert facing said at least three cylinders.
