Abstract
A coating device where the pressurized coating space formed between the doctor element and the material web and/or the counter roll carrying it is defined by a regulating plate on the inlet side relative to the material web. A guide device is so arranged in the coating space that coating mixture will circulate around it on all sides in one direction of rotation. The guide device generally leaves only relatively narrow flow channels open in the coating chamber so that harmful turbulent flows are extensively avoided which through pulsating air inclusions might lead to defects in the applied coating.
