Abstract (en)
[origin: EP0369441A2] A device for applying a thin layer of a coating material (2) onto a web (4) running over a counterpressure roller (3) by means of a slot nozzle device (1) has a vertical nozzle box (5) with an upper nozzle slot (7) between an incoming (8) and an outgoing nozzle lip (9), and a laterally built on reservoir (6) for coating material (2). In order to keep the layer thickness the same and without coating defects and marginal thick spots as a function of the rate of operation and thickness fluctuations in the web (2), the reservoir (6) is attached to the nozzle box (5) in such a way that the liquid level of the coating material (2) in the reservoir (6) and in the nozzle box (5) is essentially the same. Furthermore, it is expedient to provide in the nozzle box (5) on the path of the coating material a driven bulk transport roller (10) mounted eccentrically in a roller chamber (11). <IMAGE>
