Abstract:
Provided is a method for producing a V-ribbed belt having a plurality of V-shaped ribs extending in a longitudinal direction and arranged in a width direction. The method includes: setting a shaped structure having a plurality of ridges arranged adjacent to one another in a belt mold including a plurality of compressed rubber layer-shaping grooves arranged adjacent to one another on an inner peripheral surface of the mold; molding a belt slab by crosslinking the shaped structure set in the mold, while compressed rubber layer-forming portions face radially outward and are fitted in the compressed rubber layer-shaping grooves, the compressed rubber layer-forming portions comprised of a surface rubber layer and a core rubber layer which are to constitute surface and inner portions, respectively; and cutting the belt slab into ring-shaped pieces having two or more of the compressed rubber layer-forming portions.

Claim (Index 17):
A method for producing a V-ribbed belt including a compressed rubber 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 surface rubber layer, 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 compressed rubber layer-forming portions, which are to constitute the V-shaped ribs, by covering each of the ridges with the surface rubber sheet, which is to constitute the surface rubber layer; molding a cylindrical belt slab by using a belt mold including a plurality of compressed rubber 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 compressed rubber layer-forming portions, which have been formed in the forming the compressed rubber layer-forming portions, is fitted in an associated one of the compressed rubber layer-shaping grooves of the belt mold, the crosslinking involving integration of the shaped structure with the surface rubber sheet; and cutting the belt slab into ring-shaped pieces each including two or more of the plurality of compressed rubber layer-forming portions that are to constitute the plurality of V-shaped ribs.
