Abstract (en)
[origin: US5732628A] A sheet-conveying drum for use between units in a printing machine is provided with a plurality of gripper bridges arranged substantially circumferentially symmetrically on the drum surface. The gripper bridges hold the paper on the drum and include gripper impact strips that are adjustable substantially radially relative to the drum in order to accommodate printing materials of different thickness. Each gripper impact strip is adjusted by means of a positioning device that is arranged on the drum radially inward of the gripper impact strip and mounted so that it can move axially relative to the drum and cam the gripper impact strip radially. The axial movement of the positioning devices is brought about by two actuating devices which are mounted opposite each other on the side frames of the printing machine. The actuating devices are preferably pneumatic cylinders and are adapted so that when they are extended they periodically engage adapters on the free ends of the positioning devices as the drum rotates. When the extended actuating device engages the adaptor the actuating device cams the positioning devices in the axial direction thereby causing the gripper impact strips to move in the radial direction.
