l86,470 CAN/RF ABRASIVE ARTICLE COMPRISING ABRASIVE AGGLOMERATES SUPPORTED IN A FIBROUS MATRIX An abrasive article comprising a plurality of separated abrasive agglomerates distributed within a matrix of undulated filaments is provided. The invention also provides a method of making an abrasive article comprising forming, within a lofty open web comprising undulated filaments bonded at points of mutual contact, a plurality of separated abrasive agglomerates to provide an abrasive agglomerate-impregnated web. Articles may be prepared of the agglomerated-impregnated web per se or by laminating layers of the web together preferably under pressure. Exemplary articles include abrasive wheels, discs, belts, sheets, blocks and the like. The abrasive articles of the invention may be used to provide an article with leveled surface finish which is ready for buffing to provide a mirror-like surface. Coated abrasive belts and set-up wheels have been previously employed with some disadvantage in such applications.
