ABSTRACT:
The invention relates to an apparatus for applying, by means of a slotted nozzle device formed between a stationary incoming nozzle lip and a trailing nozzle lip, a thin layer of coating material to a porous material web that passes over a counterpressure roll, wherein a doctor bar with an essentially circular cross-sectional shape is disposed on the trailing nozzle lip; this doctor bar has on its periphery at least one flattened section that runs across the entire longitudinal extension of the doctor bar and is rotatably supported within a doctor support so that the flattened section is adjustable at a setting angle relative to the counterpressure roll.
