Abstract:
A production method of a raw edge V-belt uses a belt mold having a plurality of compressed rubber layer-shape grooves arranged adjacent to one another. A shaped structure having a plurality of compressed rubber layer-forming portions on an outer peripheral surface is crosslinked to form a belt slab, while the compressed rubber layer-forming portions fitted in the respective compressed rubber layer-shape grooves of the belt mold. The belt slab is cut into ring-shaped pieces such that one ring-shaped piece corresponds to one compressed rubber layer-forming portion.

Claim (Index 16):
A production method of a raw edge V-belt having a compressed rubber layer which forms an inner peripheral side, in a thickness direction, of the raw edge V-belt, the compressed rubber layer including a surface rubber layer constituting a surface portion of the compressed rubber layer and a core rubber layer constituting an inner portion of the compressed rubber layer, the method comprising:\n a step of forming a rubber sheet made of a first uncrosslinked rubber composition and having a plurality of ridges extending parallel to one another and arranged adjacent to one another, each of the plurality of ridges to be the core rubber layer; a step of forming compressed rubber layer-forming portions, each of which is to be the compressed rubber layer, by covering the plurality of ridges of the rubber sheet formed in the step of forming the rubber sheet with a second uncrosslinked rubber composition, which is to be the surface rubber layer; a step of forming a cylindrical object from an object formed to have the compressed rubber layer-forming portions in the step of forming the compressed rubber layer-forming portions by covering the plurality of ridges of the rubber sheet with the second uncrosslinked rubber composition, the cylindrical object having the compressed rubber layer-forming portions on its outer peripheral surface, the compressed rubber layer-forming portions extending in a circumferential direction and arranged adjacent to one another in an axial direction; a step of molding a cylindrical belt slab, using a belt mold having a plurality of compressed rubber layer-shape grooves arranged adjacent to one another in a groove width direction, by heating and pressing, toward the belt mold, and thereby crosslinking the cylindrical object, formed in the step of forming the cylindrical object, while having each of the compressed rubber layer-forming portions fitted in an associated one of the compressed rubber layer-shape grooves of the belt mold; and a step of cutting the belt slab, molded in the step of molding the belt slab, into ring-shaped pieces such that one ring-shaped piece corresponds to one compressed rubber layer-forming portion.
