ABSTRACT:
An apparatus for applying a thin layer of a coating material (2) to a web of material (4) passing over a counter-pressure roller (3), with a slot nozzle device (1) includes a vertical nozzle box (5) with an upper nozzle slot (7) between inlet (8) and outlet (9) nozzle lips and a laterally mounted storage tank (6) for coating material (2). In order to keep the layer thickness the same and without coating flaws and thickened edges according to the operating speed and fluctuations in thickness of the web of material (4), the storage tank (6) is mounted on the nozzle box (5) in such a way that the liquid level of the coating material (2) in the storage tank (6) and in the nozzle box (5) is essentially the same. Furthermore, appropriately in the nozzle box (5) is provided a driven continuous conveyor roller (10) mounted eccentrically in a roller chamber (11) in the path of the coating material ( 2).
