摘要： 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.

摘要： 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.

摘要： 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.

摘要： A surface sheet which is to constitute a surface layer and a core sheet which is to constitute a core layer are prepared. A plurality of ridges is formed on the core sheet, and the surface sheet is bonded such that the surface sheet covers the plurality of ridges, thereby forming compression layer-forming portions.
