Abstract

Sheet transfer cylinder assembly of a sheet-fed rotary printing machine including a sheet transfer cylinder and a device for correcting register of overprints on a sheet by deforming the leading edge of the sheet which includes a gripper fly supported on a shaft and swingably mounted on the sheet transfer cylinder, and a bending device carried by the sheet transfer cylinder in a middle region thereof, the bending device being cooperatively associated with the gripper fly and being actuatable by swinging movement of the gripper fly for flexing the shaft of the gripper fly and deforming the leading edge of the sheet in a direction tangential to the circumference of the cylinder.
