Abstract:
1. A printing unit of an offset rotary printing press comprising: a first printing group in the printing unit and having a plurality of first printing group components including at least a first frame cylinder, a first transfer cylinder and a first ink unit, said first printing group components having first printing group component axes of rotation extending in a first direction; a first printing group frame supporting said first printing group in the printing unit; a second printing group in the printing unit and having a plurality of second printing group components including at least a second forme cylinder, a second transfer cylinder and a second ink unit, said second printing group components having second printing group component axes of rotation extending in a second direction parallel to said first direction; a second printing group frame supporting said second printing group in the printing unit; means supporting at least said first printing group, in said first printing group frame, and said second printing group, in said second printing group frame, for cooperation with each other to act with each other as at least a first printing group pair, said at least a first printing group pair being part of the printing unit which is configured as a bridge printing unit in bridge construction, said first and second transfer cylinders of said first and second printing groups being oriented toward each other and cooperating to print a web passing between said first and second transfer cylinders while said first and second printing groups are cooperating with each other to form said bridge printing unit; and a support element supporting said at least first printing group frame and said second printing group frame of said bridge unit in the printing unit for movement of at least one of said first printing group frame and said second printing group frame in the printing unit with respect to the other one of said at least first printing group frame and said second printing group frame in said bridge unit in the printing unit formed by the cooperation of said first printing group and said second printing group in a direction parallel to said first and second printing group axes of rotation of said cylinders to separate said first and said second printing groups, which cooperate to form the printing unit, laterally with respect to each other in said direction parallel to said first and second printing group axes of rotation to separate said printing groups of the printing unit apart from each other to provide access to said components of both of said first and second printing groups in response to said lateral movement of said one of said first printing group frame and said second printing group frame in the printing unit.
