摘要

The printing cylinder support unit for a printing machine according to the invention comprises a support frame (27), supporting means mounted on the support frame, and one of a plurality of positioning elements (109). The supporting means comprise displacement means and at least three support elements (111,12,13) for each axial end of a printing cylinder (101), which support elements are designed each to interact with the positioning element at the location of a support point on the positioning element. The positioning element (109) can be connected to one of a plurality of printing cylinders (101), the positions of the support points being related to the diameter of the printing cylinder in question. The displacement means are designed to move at least two of the support elements (111,12,13) with respect to the support frame (27) so as to receive positioning elements with different support point positions. The positioning element can be connected to the support elements in a rotationally fixed manner and comprises axle support means for accommodating a rotation axle of one of the printing cylinders.
