Abstract: A cured and inverted V-belt sleeve having a plurality of spaced circumferential V-grooves that bound oversized V-belt side portions of inverted V-belts is provided by fabricating a belt sleeve with a tensile member interpositioned between inner and outer uncured elastomeric layers, skiving circumferential strips of elastomeric material from the outer layer, and molding and curing the skived belt sleeve. Individual coverless or "raw edge" V-belts or V-belts banded together at their top surfaces are provided with an optional molded circumferential depression that forms an arch in the belt bottom surfaces and juxtaposed embedded reinforcements.

Abstract: A center cord line V-belt having a longitudinally extending load-carrying tensile section of cord interpositioned between first and second layers with substantially the same fabrication construction which includes at least two plies of bias fabric disposed in an elastomeric matrix of the first and second layers near the inner and outer circumferential surfaces of the V-belt.
