Modular roller for industrial rotary cylindrical brushes, particularly for outdoor use

Abstract

A modular roller for industrial rotary cylindrical brushes, particularly for outdoor use, of the type constituted by a central support in which a plurality of tufts of bristles are fixed, the support being constituted by a cylindrical ring whose faces are cut along two mutually parallel planes that are inclined with respect to planes that are perpendicular to the direction of the axis of the cylindrical ring, the tufts of bristles that are distributed along the ring lying on planes that are substantially radial with respect to the ring and parallel to the inclined planes of the faces.

What is claimed is:  
     
         1 . A modular roller for industrial rotary cylindrical brushes, particularly for outdoor use, of the type constituted by a central support in which a plurality of tufts of bristles are fixed, said support comprising a cylindrical ring whose faces are cut along two mutually parallel planes that are inclined with respect to planes that are perpendicular to the direction of the axis of the cylindrical ring, and wherein the tufts of bristles that are distributed along the ring lie on planes that are substantially radial with respect to the ring and parallel to the inclined planes of said faces.  
     
     
         2 . The roller according to  claim 1 , wherein said planes on which the faces of the ring lie have an inclination of zero to thirty degrees with respect to planes that are perpendicular to the axis of the ring.  
     
     
         3 . The roller according to  claim 1 , wherein the tufts of bristles are made of a material such as polypropylene and/or nylon and/or polyester and/or metal.  
     
     
         4 . The roller according to  claim 1 , wherein said tufts of bristles are made of different materials.  
     
     
         5 . The roller according to  claim 1 , wherein in order to rotationally rigidly couple a pack of rollers to the driving shaft, at the beginning and at the end of the pack there are end heads, constituted by tubular bodies in which one face is inclined for resting against the outer rollers of the pack and the opposite face is flat and provided with means for locking rotation and longitudinal sliding with respect to the shaft.  
     
     
         6 . The roller according to  claim 5 , wherein said means for rotationally coupling said heads are constituted by screws screwed into corresponding radial holes of the heads.
