Abstract: Formed on the doctor element, between a chamber mouth and the paper web respectively the backing roll supporting it, is an application space which relative to the doctor element, that is, on the entrance side of the paper web, is defined by a baffle plate and kept at a pressure which exceeds atmospheric pressure. Between the baffle plate, this application space 2 is subdivided toward the doctor element (coating blade) 1, creating between the end of the vane 2 and the coating blade 1 a gap whose width ranges between 4 mm and 10 mm. This makes it possible to produce a flawless coating application also in the case of very light basis application weights.
