Abstract
Abstract An abrasive member comprises a metal film (2) attached to one surface of a flexible sheet (1), a mask (13) of plating resistant material on the exposed surface of the metal film, the plating resistant material having a multitude of discrete openings (14) therein, and metal (3) electrodeposited through the discrete openings onto the metal film in the presence of particulate abrasive material so that the material adheres directly to the metal film and the abrasive (4) is embedded in the metal deposits.
