摘要： In a sheet gripper for a sheet-processing machine, a swingable gripper arm has at one of its ends a gripper tip which can be pressed against an abutment and, at its other end, a spring section which is bent back towards the gripper tip in the manner of a bent leaf spring and connects the gripper arm to a gripper shaft. The gripper arm is of substantially inflexible construction. The bent-back spring section and the gripper tip lie on opposite sides of a plane which extends substantially perpendicular to the gripper arm and radially of the gripper shaft. The bent-back end of the spring section forms an attachment arm which rests, with a contact surface adapted to the curvature of the gripper shaft, on the side of the gripper shaft facing the gripper arm and is releasably attached to the gripper shaft by means of a screw.
