Rotary bristle tool with preferentially oriented bristles

摘要

A rotary bristle tool having a backing with a plurality of bristles extending therefrom. The bristles have a cross section and preferential orientation to control deflection during rotation of the tool. One embodiment is well suited for refining the inside surface of two-way and three-way corners. The backing and bristles are preferably integrally molded. The rotary bristle tool is molded from a moldable polymer such a thermoset polymer, thermoplastic polymer, or thermoplastic elastomer. The rotary bristle tool can include an attachment member molded integrally with the backing. Also disclosed is a method of making a rotary bristle tool and a method of refining a workpiece surface with a rotary bristle tool.
