Abstract

The bearings of a printing roller of a printing machine, preferably of a flexoprinting machine, with at least one counter-pressure cylinder and with at least one printing roller, which on one end is taper bore mounted in the frame, are conveyable in guideways relative to the counter-pressure cylinder. A bearing is provided for underpropping the shaft extension of the free end of the printing roller. In order to be able to slide the enveloping sleeve off and/or the adapter sleeve off of the printing roller in a simple manner, two shafts are mounted to be longitudinally displaceable and rotatable in the bearing block in which the printing roller is taper bore mounted, parallel to the center line of the printing roller, said shafts carrying on their inner ends, which are oriented toward the printing roller, radial arms with end face thrust pieces. The shafts are rotatably mounted on their outer ends in a carrier bracket and are provided with a rotary drive. The carrier bracket is provided with a drive that makes it conveyable relative to the bearing block.
