  • the belt table 1 has the suction belts 2 and in inside a suction box 14 for generating a negative pressure on the suction belts 2.
  • the suction belts 2 are by means of a belt roller 10 on the drive axis 8 of one separate drive, not shown here, directly or from one derived from the sheet processing machine Drive off driven.
  • the Belt roller 10 is coupled to the gear arrangement 9.
  • the System suction belts 4 are by means of a drive roller 11 the drive shaft 7 and driven by a further roller 12 out, which are arranged relatively far to the front marks 6 is. Furthermore, in the area of leadership System suction tapes 4 a tensioning device for the system suction tapes 4 may be provided.
  • the system suction tapes 4 run in Area of the level of the system table 3 via a suction box 13 between the drive roller 11 and the roller 12. By the Suction box 13 can have a vacuum at the suction openings provided suction lines 4 are generated.
  • the drive roller 11 is also like the belt roller 10 of the Belt table 1 with the gear arrangement 9 already mentioned coupled.
  • the transmission arrangement 9 is schematically in one possible embodiment shown.
  • the suction belts 2 of the belt table 1 driving, coupled drive axis 8 becomes a gear connection 17 to that with the belt roller 11, which is the system suction belts 4 of the system table 3 drives, coupled drive axis 7 led.
  • This gear connection 17 ensures that the speed of the suction belts 2 on the speed the system suction tapes 4 is transmitted.
  • the drive of the suction belts 2 in preferred Way in synchronization with the machine cycle of the sheet processing Machine between a maximum and a minimum speed accelerated and decelerated is provided.
