摘要： PURPOSE: To certainly clamp a plate at the part on the side opposite to the gripper end thereof and to reduce the cost of a stop device while enhancing registering accuracy. CONSTITUTION: Even when the stop position of the gap 14 of a plate cylinder 10 is slightly shifted, the part on the side of the gripper end of a plate is certainly pushed in the gap 14 of the plate cylinder 10 by a plate press device 21. The plate press device 21 is also shaken by the shaking device of a plate press roller 6 and the part on the side opposite to the gripper end of the plate is moved in the axial direction of the plate cylinder 10 and the rigister pin of the plate cylinder 10 is fitted in the notch groove on the side of the gripper end of the plate. Since the plate press device 21 is detachable with respect to the gap 14 of the plate cylinder 10, the plate press device 21 is moved to a detaching position when the plate is wound around the plate cylinder by the plate press roller 6 and moved to an attaching position when the part on the side opposite to the gripper end of the plate is inserted in the gap 14 of the plate cylinder 10 to enable the mounting of the plate on the plate cylinder 10.
