ABSTRACT:
A knock-off unit for knocking off sheet material from the circumferential surface of an impression cylinder in a rotary printing machine operatable in recto and in recto/verso or perfector printing modes, includes a knock-off device mounted on a rectilinear guide and controllable by a gripper shaft for lifting a leading region of the sheet material off the circumferential surface of the impression cylinder. The knock-off device is coupled via a transmission mechanism to said gripper shaft and, during an outward movement, said knock-off device being extended beyond the circumferential surface of the impression cylinder, initially bridging an idle stroke; an impression cylinder in combination with the knock-off unit; and a printing unit having the knock-off unit.
