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.
