ABSTRACT:
An endless conveyor belt is washed by a cleaning roller engaging the bottom run of the empty belt. The cleaning roller is sprayed by nozzles set counter to the direction of rotation of the cleaning roller. The surface of the cleaning roller is preferably covered with a felt-like material. Excess cleaning fluid is squeezed out by a pressure roller. A scraper, downstream of the cleaning roller, carries residual dirt or cleaning fluid remaining on the conveyor belt into the housing of the washing apparatus.
