  • the transport units or the buffers one after the other arranged are the transport units or the buffers one after the other arranged, the newly formed scale flow in the first Transport unit 302 after reaching a predetermined Number of sheets and if the second transport unit is emptied completely in one intermediate cycle the first transport unit to the second transport unit is handed over.
  • the switching device 604 activated so that while the leaves now in the second level in the manner described above and Run in, the first level is emptied clocked.
  • the advantages of the present invention are that very high sheet outputs can be achieved because it is continuous Sheets can be picked up without Change of group should be respected. Another advantage is that the forerunners and followers can be operated independently, i.e., the The cutting machine and the collecting station brake, for example not mutually exclusive. By scaling the Leaves become a slight separation or group formation allows.
