| Abstract: |
A longitudinally extending pad of a rubbery, compressible, water-absorbent material is covered with a knit fabric to provide an abrasive surface. A scraper is formed integrally at one end of the pad by applying heat and pressure to the one end to compress and harden the one end. Thus, the scraper, which comprises an elongated extension of the pad, is thin edged and relatively rigid.
