Abstract
Prevention of damages on the printing surface of plastic gravure plate is the object. Radius of the plate cylinder 14, impression cylinder 11, and transfer drum 2 located between units are identical. The plate cylinders 14, 24 and the impression cylinders 11, 21 are arranged so that the lines L1 and L2 are parallel to each other. The grippers 12, 22 are arranged so that the gripper 22 of the impression cylinder 21 is at the point P.sub.21 when the gripper 12 of the impression cylinder 11 is at the point P.sub.11. Thus, a paper sheet transferred from the impression cylinder 11 to the transfer drum 2 at the nearest point P.sub.1 is transferred by the rotation of the transfer drum 2 at the nearest point P.sub.2 by the rotation of the transfer drum 2. Since the phases of the plate cylinders 14 and 24 are in agreement, the doctor blade is stopped at the same relative location for all the units.
