A toothed timing belt is produced from a belt blank utilizing an apparatus having a belt blank fixturing device for supporting the belt blank for selective indexable rotation about a first axis and a toothed grinding wheel rotatable about a second transverse axis and supported for movement across the width of the belt blank in a direction parallel to the first axis for cutting a series of circumferentially spaced transverse teeth into the belt blank. The belt blank is indexed with each pass of the grinding wheel until the entire belt has been provided with teeth. The toothed belt blank may then be severed about its periphery to provide a plurality of discrete timing belt members.
