Abstract (en)
[origin: EP0402589A2] In the coating apparatus for paper or cardboard, a doctoring steel belt 3 which serves as a doctoring element is guided in the form of a loop over deflection rollers 8 along a corresponding roller 1 which guides the web material. The doctoring belt is driven by means of winding drums 6 and 7 which can be driven by a motor. The feed rate of the doctoring bolt is very small, for example 2 to 10 cm/min. <??>As a result, there is time to carry out a thorough cleaning process of the doctoring belt, for example by means of spray nozzles, scrapers and the like. <IMAGE>
