Abstract:
A production method of a V-belt uses a belt mold having a plurality of compression layer-shape grooves arranged adjacent to one another in a groove width direction. A shaped structure having a plurality of ridges on an outer peripheral surface is crosslinked and combined with a fabric material to form a belt slab, while the compression layer-forming portions, which are the ridges covered with the fabric material, being fitted in the respective compression 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 compression layer-forming portion.

Claim (Index 16):
A production method of a V-belt having a compression layer which forms an inner peripheral side, in a thickness direction, of the V-belt, and which has, on both sides thereof, friction transmission surfaces covered with a covering fabric, the method comprising:\n a step of forming a rubber sheet made of an uncrosslinked rubber composition having a plurality of ridges extending parallel to one another and arranged adjacent to one another; a step of forming compression layer-forming portions, each of the compression layer-forming portions to be the compression layer, by covering the plurality of ridges of the rubber sheet, formed in the step of forming the rubber sheet, with a fabric material which is to be the covering fabric; a step of forming a cylindrical object from an object formed to have the compression layer-forming portions in the step of forming the compression layer-forming portions by covering the plurality of ridges of the rubber sheet with the fabric material, the cylindrical object having the compression layer-forming portions on its outer peripheral surface, the compression 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 compression layer-shape grooves arranged adjacent to one another in a groove width direction, by heating and pressing, toward the belt mold, the cylindrical object formed in the step of forming the cylindrical object, and thereby crosslinking the uncrosslinked rubber composition and integrating the uncrosslinked rubber composition and the fabric material, while having each of the compression layer-forming portions fitted in an associated one of the compression 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 compression layer-forming portion.
