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.

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.
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.
