摘要： A replaceable buffing pad assembly including a hard surfaced, nonresilient, central support disc having first and second surfaces and defining a central opening therethrough. Drive means is disposed at the central opening for receiving a power tool to rotate the buffing pad. First and second layers of buffing material are secured on said first and second surfaces respectively. The layers of buffing material extend from the central opening on the support disc for a distance greater than the outer periphery of the support disc. The outer edges of the buffing material are secured to each other to form a continuous surface of buffing material.

摘要： 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.
摘要翻译：一种抛光垫，其中一层织物在其中缝合有簇绒材料并从其一侧向外延伸。一层粘合剂在被固定之后是柔性的，被施加到与簇绒材料延伸的织物相对的表面上。在其中具有中心形成的螺纹的金属垫圈夹在粘合剂材料和背衬层之间。背衬层具有从织物层的外边缘向内移位大量的外边缘。织物层的外周部分与延伸到其外边缘的粘合剂材料一起向上弯曲，并且弯曲部分仅由粘合剂材料保持。弯曲部分通过利用具有所需构造的模具形成，该模具形状在其固化之前与粘合剂接触并且通过对模具形式和涂覆的织物施加适当的压力并保持压力直到粘合剂固化。
