ABSTRACT:
Nail files and other abrasive articles have a structural base, such as a steel strip, coated with a slurry of a resin, such as an epoxide, and abrasive particles or grits, such as aluminum oxide, granules with sharp peaks and corners, of selected size and covered with one or more layers of electroplated metal, such as copper, nickel and chromium, forming a sheath surrounding the coated base and firmly anchoring the particles around the base. The electroplated metal has relative thick valley portions covering the bases of the particles but only has relatively thin films over the peaks of the particles. In use, the thin coatings over the peaks of the particles are broken off, exposing the tip ends of the abrasive particles for effective abrasion of surfaces, such as fingernails, rubbed thereover. The thermosetting resin material provides the initial positioning and preliminary anchoring of the abrasive particles on the base, but the sheath of electroplated metals overlying the resin coating provides the permanent anchor for the particles. The particle sizes of the abrasive granules can be controlled so that opposite faces of the file or different portions of the same face can have regulated fine or coarse abrading action.
