Abstract:
1. A composite driving belt, comprising: a carrier; and a plurality of transverse elements assembled freely slidable on the carrier, the carrier comprising an innermost endless band, each element being provided with a radially outward directed carrier contact plane for contacting a radial inner contact plane of the innermost endless band while in operation, a carrier contacting face of each transverse element and an inner contact face ( the roughness of the carrier inner contact face ( Ra′=SQRT (Ras Ras being the average roughness parameter of the carrier contacting face of each transverse element expressed in terms of the Ra surface roughness ISO-standard, and Rar being the average roughness of the carrier inner contact face of the innermost endless band expressed in terms of the Ra surface roughness ISO-standard.
