Shown are two mirror-images of each other standing cascades extending over the working plane Zu Kunststoffun g srohren 15. It is also possible to provide the support member with only a single cascade-like feed.
  • This inflow system has a membrane 90 in the upper region, which has a pressure chamber 9 which is under controllable and controllable pressure, the membrane 90 being able to bulge freely into the interior 16 of the carrier part 1 over the entire length of the device.
  • This interior 16 lies in the middle and is designed as a slotted slot that rises and falls.
  • This area of the cascade guide and also the application slot area are delimited by side walls so that a closed system is created.
  • the pressure medium is supplied via a line 17 with connected control or regulating means.
  • control means are indicated at 18 in the drawing, the control means at 19. It is thus possible to influence the internal pressure in the interior 16 and thus also the outflow pressure of the application medium on the product 5 or the web.
  • the pressure medium can be supplied to the pressure chambers 4 in the elastic pressure range through the lines 40, because control means and control means can be provided again.
  • the spring elements 3 are essential with possibly arranged, in addition to the load-bearing spring elements, stabilizing springs, which can be referred to as compression springs.
  • the through slot for the supply of the medium to the application area is provided with a crumple zone sealing the slot between the carrier part and the doctor part.
  • this crumple zone is formed by a rubber-elastic seal, preferably placed in a U-shape.
