Abstract
An apparatus by which layer thickenings formed transversely to the direction of movement of a coated web are removed after the continuously moving web has been coated with liquids or dispersions, for example a web of photographic film or paper or magnetic recording carrier, are described. A deflecting roller (4) over which the web travels with its coated side facing the roller is situated downstream of the coating and drying devices. When a layer thickening approaches, a cleaning roller (2) covered with a fleece is swung into contact with the web, whereupon the web travels only over the cleaning roller.
