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.

Claims

1. 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 a fastening mechanism 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.

2. The buffing and polishing member of claim 1, wherein the foam body further comprising, in an uncompressed state, a through bore having a first diameter portion and a second larger diameter portion.

3. The buffing and polishing member of claim 1, wherein the fastening mechanism further comprising a stem with a head portion, having a diameter larger than the diameter of the bore second diameter portion, and a snap fastener.

4. The buffing and polishing member of claim 1, wherein the snap fastener includes a male snap and a female snap interlocking with one another.

5. The buffing and polishing member of claim 1, wherein the stem includes a spindle projecting from the head portion.

6. The buffing and polishing member of claim 1, wherein a flange radially projects from the stem.

7. The buffing and polishing member of claim 6, wherein a washer, with a diameter larger than the flange, is secured onto the spindle.
