Abstract
A plate lockup apparatus for a printing press includes a leading-side lockup device, a trailing-side lockup device, and a cam mechanism. The trailing-side lockup device is located in the gap of the plate cylinder and grips a trailing edge of the plate, the trailing-side lockup device having a lockup table and a gripper plate, each having a plate gripper surface extending in a radial direction of the plate cylinder. The lockup table and the gripper plate are connected to each other at non-gripping ends thereof through a shaft. The cam mechanism has a cam, a cam surface of which is in contact with the lockup table. The cam mechanism is operated such that at a start of pivotal movement of the cam, the plate gripper surfaces of the lockup table and the gripper plate are closed to grip the plate, and at an end of pivotal movement of the cam, the lockup table and the gripper plate are moved together in a circumferential direction of the plate cylinder to tighten the gripped plate.
