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.

Abstract: A sheet material processing unit (20, 22, 24) comprises a transport system (32) for transporting sheets (12) or parts thereof from a respective input end (20i, 22i, 24i) to a respective output end (20o, 22o, 24o). A gripper unit (46) is releasably coupled to the transport system (32) and is configured for holding at least a part of one of the sheets (12). Additionally, at least one handover mechanism (47d, 47r) is provided being configured for decoupling the gripper unit (46) from the transport system (32) and providing the gripper unit (46) to a neighboring sheet material processing unit (20, 22, 24) and/or receiving a gripper unit (46) from a neighboring sheet material processing unit (20, 22, 24) and coupling the received gripper unit (46) to the corresponding transport system (32). Additionally, a sheet material processing machine (10) is presented which comprises at least two such sheet material processing units (20, 22, 24).
