Abstract

In the coating device, a covering body (1) is provided at the mouth (11) emerging from the chamber for the coating compound (10), between said mouth and the counter-roller or material web, said covering body forming, at its surface facing the mouth (11), an outlet channel (7) which leads away from the space (9) through which flows the coating compound at the coating blade (4). This outlet channel has a throttling action. Furthermore, the covering body (1) forms, with respect to the coating blade (4), a second throttling channel (8) located relatively close to the coating edge of the coating blade (4). The covering body (1) preferably ends at the outlet end of the second throttling channel (8) in a tip (16) arranged relatively close to the counter-roller or material web. Advantageously, the outlet channel (7) can be formed between a base body (5) and the covering body (1), the base body (5) ending at a distance from the coating blade (4) at most 10 mm greater than the clear width (e) of the second throttling channel (8). <IMAGE>
