  • suction air flow can be better directed thereby, so that Flow conditions can be generated more targeted, the desired Affect the substrate.
  • At least one, preferably two air guide elements on the upper and / or lower side of the printing substrate essentially in extend into the area of the transport path parallel to the substrate.
  • the plane of the spoiler elements must not necessarily parallel to Substrate lie. Deviations from such a parallel plane in the range of several degrees are quite tolerable, a stable guidance of Betigstoffrandes remains even then.
  • the substrate guide should therefore be designed so flexible that they both substrates with a maximum intended width, as well as a narrowest provided Lead substrate, or can stabilize their edges.
  • Air guide elements the suction air flow in areas of at least passed an edge of a narrowest to be expected substrate. This can be conveniently performed, or stabilized. In this way can be achieved a wide width flexibility of Betigstoff Unit.
  • the printing material guide it is provided that the air intake and the air guide elements follow the course of the transport path.
  • the printing material guide can then advantageously at different Transportpfadverierin for stabilization and guide the Beyakstoffr software worry.
  • the substrate guide is essentially always in the same plane as the transport path, even if the plane of the transport path is curving or rising other way changes.
  • the printing material guide can also be a helical one Transport path follow, as in DE 100 59 913 C2 for a turning device is presented.
  • substrates can be directed to other levels become.

  • a departure of Betikstoffrandes 5 of the flat, central position is determined by the continuous Saugluftströmung 9 prevents the top and bottom of the substrate 1.
  • a negative pressure can build up within the antechamber 12, air pumped out of this antechamber 12 by means of fans or pumping devices 13.
  • a plurality of pumping 13th be used to generate a corresponding negative pressure.
  • a desired curvature of a printing material edge 5 can be achieved by means of the invention Bedruckstoff arrangement be achieved. For this it is enough from the Suction air flow 9 on the top and / or bottom side of the printing material 1 to be controlled so that by relative pressure differences caused by different flow velocities caused a force on the substrate edge 5 acts, which bends him in the desired manner. For example, this can be the arrangement of the air passage holes 11 in the wall 10 corresponding locally be varied.
