Abstract

To permit release of one bearing (21) from an opening (6) in one side wall (1) of a printing machine, so that a cover sleeve (12) can be applied over the cylinder (3), the cylinder (3) is retained in cantilever manner supported on the other bearing (22) by an auxiliary shaft (10) extending transversely to a shaft extension (5) from the cylinder, and secured, eccentrically, in side walls (9') of a gear box (9), customarily present on the machine. For axial adjustment of the shaft extension (5) of the cylinder, the auxiliary shaft is axially movable and positionable by a pair of positioning nuts (13, 14) threaded on one shaft end (16') of the auxiliary shaft (10) which, preferably, is formed with a positioning groove (11). The auxiliary shaft (10) by being eccentrically retained in the side walls (9') of the gear box, can be rotated to clear the shaft extension (5) of the cylinder, during operation of the printing machine, and, when rotated in engaged position, provide for precise axial positioning of the cylinder (3).
