Sheet gripper on sheet-fed rotary printing presses A sheet gripper for sheet-fed rotary printing presses is described, said sheet gripper consisting of a gripper finger and a gripper support, with the gripper finger being adapted, in phase with the working of the printing press, to be swung, under the action of a gripper spring (10), into engagement and, against the action of said gripper spring, out of engagement with said gripper support, said gripper spring being supported at one end against a counter-bearing (12.) on the gripper housing (3) and at the other end against a counter-bearing on a counter-stop (3), with at least one of said counterbearings being located by holding means, said holding means being separable from one another. These separable holding means are designed in the manner of a bayonet lock and are adapted, by the movement of an inner locking part (12b) against the action of the gripper spring (10) with partial rotation of the inner locking part (12b), to be brought into engagement with one another.
