Plastic bristles for the washing brushes of automatic washing equipment

Abstract

The invention is directed towards plastic bristles for the washing brushes of automatic car washes which operate with moving brushes, where the bristles are hollow-profile bristles. The hollow-profile bristles preferably exhibit a diameter of from 0.5 to 5 mm and a round or oval cross section.

1 . Plastic bristles for the washing brushes of automatic car washes which operate with moving brushes, wherein the bristles are hollow-profile bristles.  
     
     
         2 . The plastic bristles as claimed in    claim 1   , wherein the hollow-profile bristles have a round or oval cross section.  
     
     
         3 . The plastic bristles as claimed in    claim 1    or    2   , wherein the hollow-profile bristles have in cross section a diameter in their longest direction of from 0.5 to 5 mm.  
     
     
         4 . The plastic bristles as claimed in one of the preceding claims, wherein the material of the hollow-profile bristles is selected from the group consisting of LDPE, polypropylene, polyamides, preferably PA-6, PA-66, PA-610 or PA-612, polyesters, preferably PBT.  
     
     
         5 . The plastic bristles as claimed in one of the preceding claims, wherein the alignment of the bristle equipment or the bristle set is selected transversely to a direction of rotation of the brushes.  
     
     
         6 . The plastic bristles as claimed in one of the preceding claims, wherein the bristles protrude at their end from a bristle strip or the bristles are gathered in the center into a striplike construction.
