Abstract:

A buffing pad wherein a layer of fabric has tufting material stitched therein and extending outwardly from one side thereof. A layer of adhesive which is flexible after it has set is applied to the surface of the fabric opposite that from which the tufting material extends. A metallic washer having a centrally formed screw thread therein is sandwiched between the adhesive material and a backing layer. The backing layer has an outer edge which is displaced inwardly from the outer edge of the fabric layer by a substantial amount. The outer peripheral portion of the fabric layer along with the adhesive material which extends to the outer edge thereof is curved upwardly and the curved portion is maintained solely by the adhesive material. The curved portion is formed by utilizing a mold form having the desired configuration which is brought into contact with the adhesive prior to its setting and by applying appropriate pressure to the mold form and the coated fabric and maintaining the pressure until the adhesive has set.
