ABSTRACT:
An abrasive composition prepared by kneading abrasive grains and a binder together, with addition of a filler when desired, is molded into a block, which is heated by a high-frequency wave heater and then passed between multiple pairs of rolls and thereby rolled into a sheet. Circular pieces are blanked out from the rolled sheet and subsequently baked to continuously produce resinoid wheels.
