Radial brush for grinding and polishing purposes

Abstract

Disclosed is a disk-shaped radial brush for grinding or polishing, including a plate-shaped central body having two side faces and a substantially central opening, and having a plurality of bristles radially extending away from the central body. In order to achieve an assembly of these radial brushes into brush rollers, it is proposed to provide the central body with protrusions on at least one of the side faces and with corresponding receiving members on the other side face. This allows utilizing corresponding radial brushes in brush rollers without slippage of individual radial brushes or without compressing them too much in order to avoid said slippage and thereby deforming them.

1 . A disk-shaped radial brush for grinding or polishing purposes, comprising a plate-shaped central body having two side faces and a substantially central opening, and comprising a plurality of bristles radially extending away from the central body, wherein the central body is provided with protrusions on at least one of the side faces and with corresponding receiving members on the other side face. 
     
     
         2 . The radial brush according to  claim 1 , wherein the protrusions on the one side face and the receiving members on the other side face are circumferentially offset with respect to each other. 
     
     
         3 . The radial brush according to  claim 1 , wherein the protrusions and the receiving members are designed in a substantially elongated shape. 
     
     
         4 . The radial brush according to  claim 3 , wherein the protrusions and the receiving members extend in a substantially radial direction. 
     
     
         5 . The radial brush according to  claim 1 , wherein the protrusions and the receiving members are disposed outside of an annular region surrounding the central opening. 
     
     
         6 . The radial brush according to  claim 1 , wherein the protrusions are combined into groups on the one side face.
