Definitions

  • curtain applicators are beginning to appear lately (curtain coater) in which the coating material of above the application surface of the web like a curtain and applied then applied.
  • the coating equipment relating to claim 1 of the present invention which is intended to achieve the above object, applies coating material to a web while the latter is being transported, and is characterized in that it is provided with a web which retreats at a certain angle of inclination moved down and onto which the coating material is applied, with a coating device which dispenses the coating material from above onto the web, forms a coating material curtain, which applies coating material to the web and forms a coating layer, and with a coating material scraping device, which is on the path of the web is disposed below the applicator, presses a stripping element from below in the direction of the application layer of the web running around a support roller and strips off the excess coating material from the application layer of the web.
  • the distance l 1 between the tip 8s of the air separation device 8 and the exit port of the high velocity airflow k is at 50-150 mm.
  • the coating material t on the web. 2 applies, the coating material t brings down, is prevents coating material t u.a. at the nozzle 3n of Curtain feeder 3 or in the vicinity of the discharge states what the Pollution makes cleaning and cleaning the equipment easy.
