Abstract
A device for processing a surface of a work piece. A motor is configured to produce a rotary force. A driving pulley is operatively coupled to the motor such that the rotary force produced by the motor causes rotation of the driving pulley. A belt is operatively coupled to the driving pulley such that rotation of the driving pulley causes rotation of the belt. A second pulley is also operatively coupled to the belt such that rotation of the belt causes rotation of the second pulley. Bristles are coupled to the belt and extend away from the belt. The rotary force produced by the motor causes the plurality of bristles to move relative to the motor. The surface of the work piece is processed when the bristles contacts the surface while the bristles are moving.
