PURPOSE:To easily regulate a width of a gripper end side plate vice at a plate cylinder in a direction of its axial center. CONSTITUTION:A gripper end side gripping mechanism B has a pair of stationary grippers 20 and a movable gripper 21 openably supported to the grippers 20 and capable of gripping a printing plate in cooperation with the grippers 20, wherein the grippers 20 are connected stretchably in an axial central direction of a plate cylinder 1 by a connecting member 30 having threaded parts engraved reversibly at ends, and an energizing member for energizing the mechanism in a shrinking direction is interposed between the end of the gripper 20 and an inner wall 2b of a groove 2. With this structure, when a width of the mechanism to an axial central direction of the cylinder 1 is regulated, the gripper 20 is moved by the member 30 to narrow a width of the mechanism B, and the end of the mechanism is pressure to be supported to the wall 2b of the groove 2 by the energizing member. |
