Abstract
A method and apparatus is provided for producing raw edge belts. Plural square-cut ring-shaped belts are suspended across a main spindle roller and a tension roller, and while the belts are made to run circularly, the belts are ground into V-section belts to produce raw edge belts. The ring-shaped belts are roughly ground on the main spindle roller section into belts of an almost V-form section by a rough grindstone having V-forms in its peripheral. The roughly-ground ring-shaped belts are thereafter subjected to finish polishing with a finish grindstone.
