Abstract
A buffing and polishing member has an uncompressed monolithic body of foam material having slits from an outside surface toward and less than a distance to a rotational axis of the body. The slits, on circumferential spaced planes, extend generally radially from the outside surface toward and less than a distance to the rotational axis to define a plurality of foam fingers and an unslit center portion. A fastening mechanism holds the center portion of the slit foam body in a compressed state along the rotational axis such that the uncompressed outer ends of the foam finger define a spherocylinder.
Claims9
A buffing and polishing member of compressible foam material mounted to be driven on a rotatable axis comprising:
- an uncompressed monolithic body of foam material having a slit from an outside surface toward and less than a distance to a rotational axis of the body, the slits on circumferential spaced planes extending generally radially from the outside surface toward and less than a distance to the rotational axis to define a plurality of foam fingers and an unslit center portion and the foam body, in an uncompressed state, includes a through bore having a first diameter portion and a second larger diameter portion, and a fastening mechanism is positioned in both the first and second bore diameter portions for holding the center portion of the slit foam body in a compressed state along the rotational axis such that the uncompressed outer ends of the foam finger define a spherocylinder.
