Brush roll

Abstract

A brush roll comprising a roll shaft; first brush filling material comprising either of a single yarn of a filament having a diameter of 0.1-2.0 mm and a collective fiber comprising 3-56 filaments made into a bundle; and second brush filling material comprising 100-3,000 filaments having a diameter of 0.005-0.05 mm made into a bundle, the first brush filling material and the second brush filling material being so arranged around an outside surface of the roll shaft that they can be distributed in such a relation as to be mixed with each other.

What is claimed is:  
     
         1 . A brush roll comprising a roll shaft; first brush filling material comprising either of a single yarn of a monofilament having a diameter of 0.1-2.0 mm and a collective fiber comprising 3-56 filaments made into a bundle; and second brush filling material comprising 100-3,000 filaments having a diameter of 0.005-0.05 mm made into a bundle, the first brush filling material and the second brush filling material being so arranged around an outside surface of the roll shaft that they can be distributed in such a relation as to be mixed with each other.  
     
     
         2 . The brush roll according to  claim 1 , wherein different fibers from the single yarn or collective fiber of the first brush filling material and from the collective fiber of the second brush filling material are spirally wound around an outside surface of the single yarn or collective fiber of the first brush filling material and/or around an outside surface of the collective fiber of the second brush filling material, to cover outside surface(s) thereof, and then the different fibers thus wound are impregnated with resin and solidified.  
     
     
         3 . The brush roll according to  claim 1 , wherein different fibers from the single yarn or collective fibers of the first brush filling material and from the collective fiber of the second brush filling material are plaited around an outside surface of the single yarn or collective fiber of the first brush filling material and/or around an outside surface of the collective fiber of the second brush filling material in the form of a plaited cord and, then, the different fibers thus plaited are impregnated with resin and then solidified.  
     
     
         4 . The brush roll according to any one of  claims 1  to  3 , wherein the collective fiber of the first brush filling material and/or the collective fiber of the second brush filling material are in the form of a twisted yarn or rope.
