  • the invention is based on the object to provide a device of the type mentioned, which allows a more uniform exposure to pneumatic forces on the sheet material and improved bowing.
  • a first advantage is due to the fact that the sheet material is always guided in the ideal guide plane by means of a rotatable sheet support device in the region of a pneumatic force acting on a first side, in particular resulting from a blown air dryer device.
  • scratches or Abschmier bine on the second side of the sheet material are avoidable.
  • Such disadvantages are avoidable.
  • the pneumatic force can be carried out in the hot air blown air drying on the first page of the sheet material uniformly on the sheet material, since the sheet material is always guided by the sheet support on the ideal management level and a contact of the second side an adjacent, preferably an air cushion forming sheet guiding device is avoided.
  • the blown air dryer device can advantageously be combined with a further dryer device, for example an infrared (IR) dryer device.
  • IR infrared
  • a third advantage results from the fact that the bowing is improved by a stable, flutter-free sheet run overall.
  • the sheet material is pressed against the sheet support means and simultaneously biases and sweeps the resulting from the hot air flow component of force on the blown dryer by means of sheet holding means along transported sheet material in the direction of the rear sheet edge.
  • the rotatably driven sheet support means for machine speed of the sheet conveying system has a synchronous peripheral speed.
  • the relative speed between the respective, transported in the conveying direction with machine speed sheet material and the peripheral speed of the sheet support device is approximately zero.
  • friction moments are noticeably eliminated and lubrication effects noticeably avoided.
  • a sheet-fed rotary printing machine with printing / coating works is downstream of a boom 1 in the conveying direction 8 of the sheet material.

  • the sheet conveying system 2 is designed, for example, as a chain conveyor with a sheet guiding device 7 assigned at a distance.
  • the sheet guide 7 is preferably coupled to a pneumatic system, so that preferably a floating on an air cushion sheet guide can be realized.
