Title: Suction gripper for transferring the trailing edge of a sheet in a turning device of a sheet-fed rotary printing machine

Abstract: A suction gripper for transferring a trailing edge of a sheet guided on an upstream sheet-conveying cylinder to a downstream sheet-conveying cylinder of a turning device of a sheet-fed rotary printing machine includes a holding arm. The holding arm can be extended out of the circumferential surface of the downstream sheet-conveying cylinder, to which a suction head is movably fastened. The suction head is connected to the holding arm via a spring and its movement in a direction toward a circumferential surface of the upstream sheet conveying cylinder is limited by a stop.
