Abstract
A molded brush having a backing with a plurality of bristles extending therefrom. The backing and bristles are preferably integrally molded. The brush is molded from a moldable polymer such a thermoset polymer, thermoplastic polymer, or thermoplastic elastomer. The molded brush can include an attaching means molded integrally with the backing. Also disclosed is a method of making a molded brush and a method of refining a workpiece surface with a molded brush.
Claims61
An integrally molded brush comprising:
- a flexible base having a first side and a second side, wherein said base is circular and generally planar;
- a plurality of bristles extending from said first side of said base, wherein said bristles have an aspect ratio of at least 2, wherein said bristles are generally normal to said base, and wherein said bristles are integrally molded with said base;
- and
- a threaded stud provided on the center of said base, said threaded stud being integrally molded with said base and extending from said second side of said base, wherein said threaded stud has a longitudinal axis extending normal to said base;
- wherein said molded brush comprises a moldable polymeric material substantially free of abrasive particles.
