ABSTRACT:
A seating material for assisting in the seating of brushes on motors or the like to conform a surface of the brushes to the contour of a commutator comprises a flexible base material having upper and lower major surfaces, a layer of pressure sensitive adhesive on at least a portion of the lower major surface, and alternating strips of abrasive and pressure sensitive adhesive disposed on at least a portion of the upper major surface. The strips are generally parallel and disposed at an angle with respect to the leading edge of the brushes. The material is cut and secured to the commutator of a motor. The brushes are then placed in contact with the seating material and the commutator rotated in the direction of its normal operation. The carbon dust created collects in the alternating strips of adhesive thus reducing cleanup efforts.
