Abstract
A buffing/polishing pad that is designed so that the buffing or polishing compound or dressing does not saturate or load up in the central portion of the pad. A frustro-conical cut out at the center of the pad biases buffing material towards movement from the center of the pad toward an outer peripheral edge.
Claims8
A buffing pad for use on a rotary powered buffer apparatus comprising:
- a resilient buffing pad body including a working face and a backing portion, said working face having an outer periphery and a central portion;
- and
- an outward slanted surface provided at said central portion of the pad for facilitating outward dispersion of buffing compound onto a friction area of the pad;
- wherein said outward slanted surface comprises a hollowed out frustro-conical shape through the center of the pad with the wider part of the conical frustum at the working face of the pad and the narrower portion at the rear or mounting surface of the pad, which prevents build up and saturation of compound at the center of the pad by utilizing centrifugal force to spread buffing compounds outward from the center;
- wherein said hollowed out frusto-conical shape extends through said resilient buffing pad body from said backing portion to said working face.

A buffing pad for use on a rotary powered buffing apparatus comprising:
- a resilient buffing pad body including a working face and a backing portion, said working face having an outer periphery and a central portion;
- and
- a frustro-conical surface formed at said central portion with the wider portion of the conical frustum at the working face of the pad, whereby build-up of material at the center of said pad is prevented by said frustro-conical surface biasing any buffing material in the center toward movement onto the friction area of the pad;
- wherein said frusto-conical surface extends through said resilient buffing pad body from said backing portion to said working face.
