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.

Claim (Index 1):
A method for producing a V-ribbed belt including a compression layer which forms an inner peripheral portion of the V-ribbed belt in a thickness direction of the V-ribbed belt, and which has a plurality of V-shaped ribs extending in a longitudinal direction of the V-ribbed belt and arranged in a width direction of the V-ribbed belt, the plurality of V-shaped ribs having a friction drive surface covered with a covering fabric, the method comprising:\n forming a shaped structure having a cylindrical shape, being made of an uncrosslinked rubber composition, and including, on an outer peripheral surface thereof, a plurality of ridges extending in a circumferential direction and arranged adjacent to one another in an axial direction of the shaped structure; after formation of the ridges, forming compression layer-forming portions, which are to constitute the V-shaped ribs, by covering the previously formed ridges with a fabric material, which is to constitute the covering fabric; molding a cylindrical belt slab by using a belt mold including a plurality of compression layer-shaping grooves arranged in a groove width direction, and by crosslinking the shaped structure, which has been formed in the forming the shaped structure, through heating and pressing the shaped structure toward the belt mold, while each of the compression layer-forming portions, which have been formed in the forming the compression layer-forming portions, is fitted in an associated one of the compression layer-shaping grooves of the belt mold, the crosslinking involving integration of the shaped structure with the fabric material; and cutting the belt slab into ring-shaped pieces each including two or more of the plurality of compression layer-forming portions that are to constitute the plurality of V-shaped ribs.
