Abstract: A resilient sheet gripper for a sheet-fed rotary printing press having a clamping member secured to a gripper shaft and a pivoting gripper finger resiliently connected to the clamping member by an adjustable compression spring is provided, including eccentric bushings mounted on the gripper shaft, the gripper finger being journaled thereon, so as to impart a positive gripper closing movement substantially perpendicular to a gripper support.
