  • curtain coating This technique is referred to in the art as curtain coating, wherein the order is carried out without excess of medium. This means that only as much medium is applied as ultimately to remain on the material web.
  • a device for weakening the entrained by the running surface air boundary layer is known.
  • both a suction device, elastic scrapers, brushes, a blowing device, an electrode assembly and an ultrasonic source are used alternately.
