Sheet
processing machine (01) with a
transport system (1200) designed as a chain gripper
system (1200) and several units (100; 200; 300; 400; 500; 600; 650; 700; 800; 900), wherein the chain gripper
system (1200) comprises several chain gripper carriages (1201) which are arranged attached to a chain (1203), and wherein the several chain gripper carriages (1201) are arranged to be movable at least partially in a transport direction (T), and wherein the sheet
processing machine (01) comprises at least one register device (1207) for aligning at least one chain gripper
carriage (1201) with an associated unit (200; 300; 400; 500; 650) at least in the transport direction (T), and wherein the at least one register device (1207) comprises at least one register element (1208) and wherein the at least one register element (1208) is arranged in a register state cooperating with the at least one chain gripper
carriage (1201) and wherein the at least one register element(1208) is arranged in the registered state projecting into the intended transport path for the at least one chain gripper
carriage (1201), and wherein the at least one register device (1207) and the at least one chain gripper carriage (1201) are arranged to be
convertible from a registered state to an extended state, and wherein the at least one chain gripper carriage (1201) is arranged in the extended state offset from the registered position to an extended position at least in the transport direction (T), characterized in that the at least one register element (1208) in the registered state aligns the at least one chain gripper carriage (1201) to the respective associated unit (200; 300; 400; 500; 650) and fixes it in a
special position relative to an associated unit (200; 300; 400; 500; 650) at least opposite to the transport direction (T), and that the at least one register element (1208) in Exit state in the register position of the register stateis arranged.
