A raw-edged V-belt which is of the type embodying at least a top cover layer, reinforcement insert means, and a substantially trapezoidal-shaped core formed of an elastomer. According to important aspects of the invention, the top cover layer is formed of a fiber fleece or a wide-meshed fabric completely impregnated with an elastomer. If desired, the raw-edged V-belt construction of the invention may further be equipped with a bottom cover layer. The invention further contemplates that one or both cover layers of the V-belt consist of an elastomer of low modulus of elasticity, but higher breaking elongation, than the elastomer of the core.
