Abstract
Removable print roll sleeves are changed on a printing press without removal of a respective print roll from the press frame by securing the position of the print roll on the drive side axle bearing while the outboard axle bearing for the roll is removed. A bracket on a support tree has a motorized strut which bears upon an extension of the print roll axle shaft from the drive side axle bearing. This support tree may be rotated 90.degree. about a vertical axis when not in use for minimum interruption and storage. On the outboard side of the print cylinder, the axle shaft bearing is mounted on a bearing carriage for disengagement from the axle shaft journal and withdrawn by a lead screw at a 45.degree. angle along a slide plate.
