  • Patent number: 4874478
    Abstract: A method of forming an abrasive member comprises fixedly attaching a metal film to one surface of a flexible sheet, applying a mask of plating resistant material to the exposed surface of the metal film, said plating resistant material having a multitude of discrete openings therein, and electrodepositing metal through said discrete openings onto said metal film in the presence of particulate abrasive material so that the material adheres directly to said metal film and the abrasive becomes embedded in the metal desposits.

  • Patent number: 4826508
    Abstract: In the production of an abrasive member, an apertured mask, preferably formed of a resin such as polyvinyl chloride, is applied to one surface of a length of flexible, preferably electrically conducting fabric. A metal, such as nickel, is electrolytically deposited on the fabric through the apertures in the mask in the presence of abrasive particles. The fabric may be in the form of a conductive mesh, in which case it can be laminated onto a tough backing material. Alternatively, tough backing material, for example made of poly-aramid yarn, can be rendered conductive by coating it with vaporized metal, the metal deposits being formed directly in the coated backing fabric. This process simplifies manufacture and allows production on a continuous basis with greater throughput at lower cost.
