Abstract
Poly-V belt, particularly for driving accessories of an internal combustion engine, comprising a cord realized from a yarn composed of a plurality of filaments by means of a first twisting in which are formed at least two plied yarns each composed of at least one yarn and a second twisting in which the plied yarns are twisted together to form the cord; the first twisting and the second twisting are made in opposite directions, and the numbers of twists per meter of the two twisting steps are calculated so that in the finished cord the filaments form with the axis of the cord an angle smaller than 3.3°.
