ABSTRACT:
This invention is concerned with a superior rotary brush wherein an elongated brush member is coiled in a helical fashion around a central shaft or cylinder which incorporates a plurality of projections on its outer periphery. The elongated brush member is bent around the projections of said shaft or cylinder in such a fashion that its inner periphery is non-arcuate. The inner periphery of said elongated brush member forms a plurality of cords which generally circumscribe the central shaft or cylinder. In use the inner periphery of the elongated brush member engages the projections as are contained on the central shaft or cylinder in such a manner that movement of the elongated brush member in relation to central shaft or cylinder is prevented.
The subject invention is particularly advantageous in that the forces which result from the engagement of the brush filament of the elongated brush member with a work piece are transmitted directly to the elongated shaft or cylinder and not to the fasteners whereby said elongated brush member is attached to said elongated shaft or cylinder.
