ABSTRACT:
In a sheet-fed rotary printing press, a sheet gripper has a gripper finger and a gripper support, the gripper finger being swingable, in operating phase with the printing press, under the action of a gripper spring, into engagement with the gripper support and, against the action of the gripper spring, out of engagement with the gripper support, the gripper spring being supported at one end thereof against a counter-bearing on the gripper finger and, at the other end thereof, against a counter-bearing on a gripper housing, and includes a holding device separable from one another for fixing at least one of the counter-bearings, the holding device being in mutual agreement and being disposed on the counter-bearing as well as on a part of the printing press wherein the counter-bearing is mountable, the separable holding device being formed of an inner locking part and an outer locking part of a bayonet lock, at least one of the locking parts having projections and the other of the locking parts having holding surfaces for the projections, the projections and the holding surfaces being engageable with one another from behind by a movement of one of the locking parts against the action of the gripper spring and by a partial rotation of the one locking part.
