Abstract

A rotating drum has a gripper bar mounted for cooperation therewith to convey sheets. The gripper bar is manually moved from a stationary first position spaced from the rotating drum to a second position to grip the sheet against the drum and rotate therewith. After moving through a predetermined angle, the eccentric mounting of the gripper bar causes the bar to move away from the drum and assume the stationary first position. [US3918707A]
