Abstract
A sheet processing device has a moveable beam (36) that moves in the vertical direction, a gripper bar (30) for gripping a sheet that travels through the sheet processing device (10), and a gripper bar locking device (40) that can lock the gripper bar (30) in a precise position. The gripper bar locking device (40) has a locking lever (68) that is pivoting between a rest position and a locking position. The locking lever (68) is connected to a vertical linear guide coupled with the moveable beam (36) resulting in a precise, compact and simple system to lock the gripper bar.
