Abstract
A cleaning system for cleaning a coating agent feed system and nozzles used for coating a fiber. The coating agent feed system comprises a feed channel for feeding coating agent from a coating agent tank into a coating agent chamber situated in a nozzle unit, between two nozzles, and a fiber inlet channel for guiding the fiber to be coated through a first nozzle into the coating agent chamber and a fiber outlet channel for guiding the fiber through a second nozzle out of the coating agent chamber. For an intensified cleaning function, the cleaning system comprises a second feed channel for steeping agent, positioned in the nozzle unit. The feed channel opens into the coating agent chamber. A change valve is arranged between an outlet end of the coating agent feed channel at the coating agent chamber and an outlet end of the second feed channel at the coating agent chamber, the change valve being arranged to close the second feed channel in one position and the coating agent feed channel in the other position.
