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.
A polishing buff comprising: (A) a fabric layer defining a central aperture and having first and second sides; (B) tufted material stitched into said fabric layer and extending outwardly from said first side thereof only; (C) a layer of flexible adhesive completely covering said second side of said fabric and the stitches of said tufted material; (D) the entire peripheral portion of said fabric and the tufted material thereon being permanently curved, said adhesive layer constituting the sole means for maintaining said curved configuration of said peripheral portion; (E) a metallic washer having a central aperture defining a screw thread; (F) a backing layer having a central aperture; (G) said washer being sandwiched between said fabric and said backing layer with said central aperture aligned; (H) said washer and said backing layer being secured to said fabric layer only by said adhesive; and (I) said backing layer having an outer edge displaced inwardly from the outer edge of said fabric whereby said backing layer does not extend onto said curved peripheral portion.
