Definitions

  • the invention relates to a device for coating a strip-shaped carrier material, which is passed over a rotating coating roller with a coating nozzle, through the coating gap a layer on the carrier material can be applied and with a device for exerting negative pressure on the applied Layer, wherein a pressure chamber is present in the interior of the which leads a distribution channel to the outside.
  • Such a device is known from US-A-3,640,752, which describes a method and describes a device for coating a carrier material, in which gas through a slot tangentially to the substrate in the opposite direction the movement of the carrier material is guided.
  • the gas serves the air layer on the carrier material and those adhering to the surface of the carrier material Remove dust and pressure in a room below the job site to reduce the layer to be applied to the carrier material.
  • a special facility for generating a vacuum and a vacuum channel provided for this purpose are not known from this document.
  • LU-A-0 057 983 describes an apparatus for applying a layer on a Material web that is guided over support rollers.
  • the device consists of a Spreading shoe and an extrusion head. Between the petting shoe and the Back-up roller is a passage gap for the layer to be applied.
  • a Sealing device prevents air from being carried through the material web into the Brush zone and consists of either an elongated slot in the shoe on the inlet side into the passage gap tangentially against the inlet direction the web is set, formed, or from a weather strip, which on Is attached and in slight frictional contact with the material web stands.
  • the elongated slot mentioned above counteracts air under pressure guides the web of material, thereby preventing that of the web of material Enter entrained air layer in the gap between the coating and material web can. There are no facilities provided that a negative pressure in the area of could exert coating gap on the layer to be applied.
  • US-A 4,445,458 is an extrusion coating device for the application a coating solution on a strip material moving over a roller known with a trigger nozzle that has an inclined trigger surface, the angle between the withdrawal surface and the axis of the extrusion slot is an obtuse angle.
  • the extrusion coating device is with a vacuum box equipped with the greater belt speed of the strip material entrained air should reduce the contact of the meniscus of the coating solution to not destroy the tape.
  • the vacuum is with a not described in detail Vacuum pump generated outside the vacuum box. Form and the sealing of the vacuum box is not described in detail.

  • the vacuum space is countered by moving webs Normal pressure in the area of the coating roller and Band material through one or more narrow gaps or separated by adjacent seals.
  • the adjacent seals can be worn or worn Surface defects of the coating roller or the Guide tape material.
  • These high amounts of air entering change, depending according to the width and thickness of the strip material, so that the Vacuum or the gap seal each new must be set.
  • the air volumes are furthermore the cause of turbulence and Vibrations that affect the coating meniscus, i.e. the Application bead of the coating solution can.
  • the object of the invention is a coil coating system with a device to create a negative pressure so that it without the usual Vacuum box is equipped and a largely vibration and cross flow free Negative pressure generated.
  • This object is achieved in such a way that in operation a nozzle wall is attached to the inside of the device with a portion of the substrate forms a vacuum channel on the coating roller and that the distribution channel narrows and merges into a Laval nozzle that extends across the entire coating width of the carrier material and at their narrowest cross section with a Diffuser part of an outlet channel is connected, so that when in operation a gas stream with excess pressure in opposite direction to the running direction of the carrier material tangential to the Vacuum channel emerges from the outlet channel, a vacuum in the vacuum channel is produced.
