    Abstract: A coating device for a material web, such as a paper or cardboard web, is provided. A doctor band, serving as a doctor element, is run over reversing rolls in the form of a loop and along a backing roll that supports the material web. A doctor band drive is provided by take-up drums that can be driven by a motor. The feed of the doctor band is very low, for instance, 2 to 10 cm/min. This provides sufficient time for performing a thorough cleaning of the doctor band. The band may be cleaned by means of nozzles, scrapers and the like.
