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.
