Abstract

The control device for a suction gripper on a guiding cylinder of a sheet fed rotary press comprises a tumbler shaft mounted on the sheet guiding cylinder and a suction unit swingable about a pivot point which is supported for movement about the tumbler shaft. The suction unit is either positively driven by a cam drive or self-adjustable by means of a tension spring between the unit and the tumbler shaft.
