Abstract: A brush segment, a brush element, a brush assembly, and methods of making and using the same are disclosed. The brush segment includes a center portion with inner and outer edges. The center portion also includes first and second side edges. A plurality of bristles extends outwardly from the outer edge. The inner edge includes an interlock arrangement. The side edges have an attachment arrangement for attaching adjacent segments. The brush element includes a center portion and inner and outer edges. A plurality of bristles extends outwardly from the outer edge. The inner edge includes an interlock arrangement for restraining rotation of adjacent elements assembled into a brush assembly. Two or more brush elements are secured together to form a rotary brush assembly.

Abstract: A molded brush segment having a plurality of integrally molded bristles extending from a generally planar center portion. The brush segment is molded from a moldable polymer, such as a thermoplastic elastomer, and has a plurality of abrasive particles present in at least the bristles of the brush segment.
