Abstract

A buffing pad assembly is provided for buffing, polishing or otherwise finishing a painted surface. The buffing pad assembly includes a rigid backing mount, a back-up pad affixed to the backing mount, and a buffing pad removably attached to the back-up pad by way of fastening material provided on the back-up pad and the buffing pad. The buffing pad has a number of channels extending completely through the pad to facilitate dissipation of heat generated by friction during use of the buffing pad. The back-up pad and the fastening material are designed to accommodate the heat dissipation channels in the buffing pad so that the channels are substantially unobstructed. Additionally, a centering system is provided on the buffing pad assembly to facilitate alignment of the buffing pad during use.

Independent Claims | See all claims (22)

  1. 1. A buffing pad assembly adapted for use with a buffing machine, the buffing pad assembly comprising: a backing mount adapted to secure the buffing pad assembly to the buffing machine; a back-up pad, having an upper and lower surface, secured at its upper surface to the backing mount; a buffing pad, having a front buffing surface and a rear mounting surface surrounded by a raised annular centering lip, wherein the buffing pad is removably attached at its rear mounting surface to the lower surface of the back-up pad; and means for dissipating heat generated at the front buffing surface of the buffing pad during use of the buffing pad assembly, wherein the means for dissipating heat comprises a plurality of apertures extending through the buffing pad from the front buffing surface to the rear mounting surface, and wherein an upper end of the plurality of apertures is substantially unobstructed.
  2. 4. A buffing pad assembly adapted for use with a buffing machine, the buffing pad assembly comprising: a backing mount adapted to secure the buffing pad assembly to the buffing machine; a back-up pad, having an upper and lower surface, secured at its upper surface to the backing mount; a buffing pad, having a front buffing surface and a rear mounting surface surrounded by a raised annular centering lip, wherein the buffing pad is removably attached at its rear mounting surface to the lower surface of the back-up pad; and means for dissipating heat generated at the front buffing surface of the buffing pad during use of the buffing pad assembly, wherein the means for dissipating heat comprises a plurality of apertures extending through the buffing pad from the front buffing surface to the rear mounting surface, and wherein the back-up pad has a configuration with sections of the back-up pad having gaps to accommodate the plurality of apertures in the buffing pad.
  3. 10. A buffing pad assembly adapted for use with a buffing machine, the buffing pad assembly comprising: a backing mount adapted to secure the buffing pad assembly to the buffing machine; a back-up pad with a non-circular configuration having an upper and lower surface, said back tip pad being secured at its upper surface to the backing mount; a buffing pad, having a front buffing surface and a rear mounting surface removably attached at its rear mounting surface to the lower surface of the back-up pad said buffing pad including an axially aligned centering aperture extending from the front buffing surface to the rear mounting surface, and wherein said buffing pad has on its rear surface a layer of fastening material with a configuration adapted to accommodate apertures in the buffing pad itself, and wherein the layer of fastening material on the rear mounting surface of the buffing pad includes an axially aligned centering aperture, and means for dissipating heat generated at the front buffing surface of the buffing pad during use of the buffing pad assembly.
  4. 17. A buffing pad assembly adapted for use with a buffing machine, the buffing pad assembly comprising: a backing mount adapted to secure the buffing pad assembly to the buffing machine; a back-up pad, having an upper and lower surface, secured at its upper surface to the backing mount; a buffing pad, having a front buffing surface and a rear mounting surface surrounded by a raised annular centering lip, wherein the buffing pad is removably attached at its rear mounting surface to the lower surface of the back-up pad, and wherein the back-up pad has a non-circular configuration; means for dissipating heat generated at the front buffing surface of the buffing pad during use of the buffing pad assembly; a layer of fastening material on the rear mounting surface of the buffing pad, and a layer of fastening material on the lower surface of the back-up pad, wherein the layer of fastening material on the lower surface of the back-up pad has a non-circular configuration, and wherein the buffing pad assembly further comprises means for automatically aligning the layers of fastening material with one another.
  5. 20. A buffing pad assembly adapted for use with a buffing machine, the buffing pad assembly comprising: a backing mount adapted to secure the buffing pad assembly to the buffing machine; a back-up pad having an upper and lower surface, secured at its upper surface to the backing mount; a buffing pad, having a front buffing surface and a rear mounting surface surrounded by a raised annular centering lip, said buffing pad removably attached at its rear mounting surface to the lower surface of the back-up pad; a plurality of apertures extending through the buffing pad from the front buffing surface to the rear mounting surface; a layer of fastening material on the rear mounting surface of the buffing pad engageable with a layer of fastening material on the lower surface of the back-up pad; and a centering post projecting from and mounted on a top surface of the layer of fastening material on the rear mounting surface of the buffing pad, and a corresponding socket defined in the back-up pad.
