Mounting for printing cylinder in rotary printer, with bearing bush

摘要

The bearing bush (3) of the printing cylinder is held during operation by a jaw chuck. The jaws (4,5) with circular-curved clamping surfaces (6,7) are splayed apart for the sleeve to slide axially onto the cylinder body. The bearing bush has a locking bolt (9) axially movable in a radial guide hole (8). The bolt has a radial through-hole through which passes a sprung steel wire (12) whose two ends protrude at both ends. The bearing bush is movable in relation to a cylinder pin (1) positioned by a printing cylinder drive.
