Definitions

  • the invention relates to a device for cleaning a sawtooth all-steel set to the preamble of claim 1.
  • Cleaning brushes are usually used for this purpose, those outside the actual working area of the drum, or the drum are arranged and one parallel to rotate around an axis of rotation of the drum extending axis of rotation.
  • the cleaning brush bristles run through during the cleaning process the set and remove impurities the clothing alleys. After leaving the service alleys the contaminants then usually with a suction device or the like. Removed from the cleaning brushes, so that with the cleaning brush bristles on the next pass through the sawtooth all-steel set no new impurities entered become.
