Abstract

A sheet gripper for a rotary press is provided having a hooked gripper finger pivotably connected at its lower end to a clamping element, and a roller disposed upon the gripper finger is biased against the guiding surfaces of a finger support element to ensure smooth changes from open and closed gripper finger positions, substantially without any vibrational motion or displacement resulting in the plane of sheet motion. Preferably, a compression spring is mounted in the clamping element to bias the roller against the gripper support element, the element having a rectilinear guide surface disposed substantially perpendicularly to a retaining surface, and a cam surface which extends upwardly and inclined outwardly from the rectilinear guide surface. Upon oscillation of the gripper shaft, the roller is guided along the rectilinear guide surface and cam surface, thereby defining accurate gripper finger motion.
