BUFFING BALL MADE OF FOAM MATERIAL

摘要

A buffing and polishing ball made of a compressible polymeric foam material is formed by slitting a body of foam material in a substantially uncompressed state (1) from an outside surface of the body in a direction generally perpendicular to the rotational axis and (2) on circumferentially spaced planes that extend generally radially from the outside surface of the body to define a plurality of foam fingers. A fastening system is used to compress and hold a center portion of the foam body in a direction along the rotational axis such that the uncompressed outer ends of the fingers assume a generally spherical ball.
