ABSTRACT A gripper mechanism for printing press folding machines or other sheet handling equipment comprises a rigid holder mounted on a pivot shaft and a resilient gripper finger, fixed to the holder, which pivots into engagement with an angled clamping surface. The geometry of the gripper finger relative to the holder is such that the rigid holder and resilient finger act as a linkage which, upon application of counterforce by the clamping surface, imparts a radial component of force to the gripper tip equal and opposite to the radial component of counterforce, thereby producing non- sliding engagement of a sheet of paper positioned between the clamping surface and said tip.
