Definitions

  • the invention relates to a device for guiding sheets in a sheet processing Machine with a feed table and provided at the front edge of the feed table Front and cover marks existing feed marks and arranged in the feed table, Blowing air in the direction of sheet travel leading between the feed table and the underside of the sheet Nozzles.
  • Such a device is known from DE 11 86 473, in which in the space between the Side pull marks and the contact marks from recesses between a cover strip and the feed table blowing air is directed in the direction of sheet travel.
  • Such a device is known from DE-G'M 82 25 956, in which for Generation of a blown air flow in the sheet transport plane nozzles are provided with at least two separate, differently inclined to the transport level Nozzle channels are provided.
  • the volume flow of the blowing jet should thus increase and decrease disadvantageous adhesion of the sheets to the feed table can be prevented.
  • the object of the invention is to provide a device which enables trouble-free Realize sheet transport in the area of the feed table.
  • the solution according to the invention ensures with simple means that, on the one hand the sheets for processing against the feed table and their leading edge under the cover marks are guided against the front marks, on the other hand it is avoided that the sheets stick to the feed table or the sheet run also disadvantageously influenced by flutter.
  • Figure 1 is a section of a feed table 4 with a distance from each other and over the Width of the feed table 4 arranged flow channels 9 shown.
  • the flow channels 9 run inclined to the sheet running direction 10, the flow channels 9 are directed obliquely outwards.
  • a blow nozzle 1 is assigned to each flow channel 9, by means of one or more pressure chambers arranged distributed over the width of the feed table 5 can be supplied with blown air.
  • the pressure chambers 5 and the blowing nozzles 1 are included a cover plate 7 covered, which forms a plane with the surface of the feed table 4.
  • Suction hole 6 provided in connection with the atmospheric pressure stands.
