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 21):
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 setting a shaped structure and a fabric material which is to constitute the covering fabric in a belt mold such that the shaped structure and the fabric material are respectively positioned inside and outside with respect to each other, the 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, the belt mold including a plurality of compression layer-shaping grooves arranged in a groove width direction; molding a cylindrical belt slab by crosslinking the shaped structure set in the belt mold through heating and pressing the shaped structure toward the belt mold, while each of compression layer-forming portions is fitted in an associated one of the compression layer-shaping grooves of the belt mold, the compression layer-forming portions being comprised of the plurality of ridges, of the shaped structure, each covered with the fabric material and together forming the compression layer, 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, wherein the belt mold has a cylindrical shape including, on an inner peripheral surface thereof, the plurality of compression layer-shaping grooves extending in a circumferential direction and arranged adjacent to one another in an axial direction of the belt mold, the shaped structure is placed in the belt mold, the shaped structure is pressed toward the belt mold by expanding an expansion sleeve disposed inward of the shaped structure and by causing the expansion sleeve to press the shaped structure from inside, a tensile member is provided between the shaped structure and the expansion sleeve, the tensile member being comprised of an uncrosslinked rubber composition formed into a cylindrical shape and having a cord embedded therein and forming a helical pattern with pitches in an axial direction of the tensile member, the tensile member is provided on the expansion sleeve before the expansion sleeve is expanded, and a gap is provided between the tensile member and the expansion sleeve before the expansion sleeve is expanded.
