Abstract
A semishell-shaped gripper apparatus for sheet-fed printing machines includes a gripper of low mass, which is fastened without play on the gripper shaft and minimizes the sliding of the gripper tip on the printing carrier. This is achieved by having the gripper finger surround the gripper shaft in such a way that separate effective engagement surfaces are formed. The effective engagement surfaces are disposed on the gripper shaft with frictional engagement and, in conjunction with the resultant force, form a triangle of forces. The gripper holder has a depression running parallel to the gripper shaft connecting to the lower edge of a web on the gripper finger in a releasably positive-locking manner. The gripper tip has a raised holding surface which has tapering radii on its periphery.
