  • the suction cup 12 has a plurality of axially parallel suction channels 15 to which the suction openings arranged on the circumference 13 directly connected radially outward are.
  • each axially parallel suction channel 15 can be one arranged in the drive shaft 8 of the knife roller 6 Connect vacuum main duct 16.
  • a suction air selector ring is used for this 17, which according to the exemplary embodiment is approximately in the Middle of the knife roller 6 (Fig. 2) e.g. with the help of a Screw 18 is fixed and the targeted supply of ensures individual suction channels 15 with negative pressure.
  • each of the Suction channels 15 in the suction cup 12 is assigned.
  • each of the suction channels 15 shown in FIG. 3 to the negative pressure prevailing in the negative pressure main channel 16 connect, still according to the embodiment a radial bore 21 from the negative pressure main channel 16 leads to the inner circumferential groove 19.
  • the location as well as shape and The shape of the inner circumferential groove 19 is finally chosen so that by adjusting the suction air selection ring 17 each suction channel 15 in the suction cup 12 can be reached.
  • connection opening 22 in each suction channel 15 and the radial bore 20 in the suction air selector ring 17 assigned.
  • the connection openings 22 of all Suction channels 15 that are not connected to the radial bore 20 of the suction air selector ring 17 are connected to atmospheric pressure, so that even in the suction channels 15 themselves and their Suction openings 13 There is atmospheric pressure.
  • the generation of the required negative pressure in the negative pressure main channel 16 in the drive shaft 8 takes place in basically known manner with the help of a suction air control head 25.
  • the drive shaft 8 extends with their negative pressure main channel 16 into the control head 25 and there carries a non-rotatably connected control disk 26.
  • Die Control disk 26 has a radially directed bore 27 and an axially directed one connected to the bore 27 Window 28 open. In a position facing the window 28 there is also a window 29 in the control head 25, to which the suction line 14 is connected.
  • the front and the window 29 facing the control disk 26 extends with the window 28 in a coordinated manner arcuate in such a way that in the negative pressure main channel 16 and correspondingly, a negative pressure in one of the suction channels 15 there is a blank over the relevant suction channel 15 3 from the takeover of the guide roller 9 to Delivery to the deflection roller 10 by suction air from the knife roller 6 is held and transported. 1 is this is the case over a little more than 180 °, the axis of the Knife roller 6 lies lower than the axis of the further transport Deflection roller 10. The axis of the other deflection roller 9 is again somewhat higher than that of the deflection roller 10th
