ABSTRACT:
A brush assembly adapted to be rotated about an axis has a brush having a flexible, annular and generally cylindrical collar generally centered on the axis and having a predetermined and generally uniform radial thickness, a predetermined inside diameter, and a predetermined axial length, and a plurality of arrays of radially projecting bristles angularly equispaced about the collar and defining a plurality of axially throughgoing and angularly equispaced bristle-free zones. A holder for the brush has a core body having a plurality of surface portions radially equispaced from and angularly equispaced about the axis and lying substantially on a cylinder centered on the axis and having a predetermined outside diameter substantially smaller than the inside diameter of the collar, inner and outer end flanges axially flanking the core body and spaced axially apart by a predetermined axial distance longer than the axial length of the collar so that the collar is received with axial play between the flanges, and respective retaining tongues extending axially from one of the flanges toward the other flange in the bristle-free zones of the brush. The tongues have inner surfaces spaced radially outward from the cylinder of the core body by a radial spacing substantially greater than the radial thickness of the collar so that the collar is received with radial play between the surface portions and the tongues.
