Abstract
A shaped structure and a fabric material are set in a belt mold such that the shaped structure and the fabric material are respectively positioned inside and outside with respect to each other. While each of compression layer-forming portions comprised of ridges of the shaped structure covered with the fabric material is fitted in an associated one of compression layer-shaping grooves of the belt mold, the shaped structure is pressed toward the belt mold and heated to be crosslinked, and integrated with the fabric material, thereby molding a cylindrical belt slab. The belt slab is cut into ring-shaped pieces having two or more of the compression layer-forming portions.
