Abstract (en)
[origin: US4759290A] A device for controlling the opening of a plurality of sheet grippers in a sheet-fed rotary press wherein the grippers are arranged to form a row on a gripper shaft disposed on a rotating cylinder. The gripper shaft is centrally controlled between its ends by two cam control systems acting in parallel relationship on the ends of an actuating shaft, by turning of the latter, with a central adjusting means interconnecting the actuating shaft and the gripper shaft to provide a symmetrically divided torsional force adjustable to vary the opening width of the grippers according to the sheet thickness being processed.
