  • a cylindrical abrasive brush comprising a roller body having a roller core in the form of a shaft and a roller sleeve in the form of a tube surrounding the shaft. End caps are mounted on the front side of the tube and support the shaft, which protrudes axially beyond the end caps.
  • a first fabric strip is wound helically.
  • a second fabric strip is wound helically on the wound-up first fabric strip, which carries bristles on its outer side.
  • the adhesive ensures that the second fabric strip adheres well to the first fabric strip.
  • the adhesive gives the composite structure strength.
  • the cleaning roller is configured as a shampooing or application roller and comprises a cylindrical roller body with bearing elements. On the lateral surface of the roller body two strips of absorbent elastic material are wound helically. The strips are glued or welded to the outer surface of the roll body and gaps between the longitudinal sides of the strips provided in which bristle bundles are arranged. The bristle bundles are inserted radially aligned in the roller body and also extend helically over the circumference of the roller body.
  • Object of the present invention is to develop a cleaning roller of the type mentioned in such a way that it has a structurally simpler structure and can be manufactured with lower production costs for different floor cleaning machines, with the use of cleaning roller, the risk of damage to the floor surface to be cleaned is low.
