Abstract: A rotary buffing and finishing pad assembly includes a polymeric foam cushioning layer that has a graded compression load deflection which is interposed between a backing plate and a relatively thin performance layer that is removably attached to the foam cushioning layer. Alternate constructions for providing a graded cushioning effect are also disclosed.

Abstract: A surface finishing ball of compressible material, adapted to be driven on a rotational axis is made from a layered body of compressible material that is formed in multiple disk-like layers that are separated in planes generally perpendicular to the rotational axis. Layers are also slit on circumferentially spaced planes that extend generally radially from an outside surface to define a plurality of foam fingers. A clamping system is used to compress and hold a center portion of the layered body in a direction along the axis of rotation such that the uncompressed outer ends of the fingers define a generally spherical ball.

Abstract: 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 finger assume a generally spherical ball.
