A driving belt provided with a carrier and a plurality of transverse elements assembled slidably thereon, the carrier comprising one or more band packages provided with a plurality of endless metal bands disposed radially around each other. …<??>The friction between the endless bands is decreased by providing at least one of said bands, at least at one side (2), with a surface profiling preferably with a roughing value between 0.30 and 0.75 mu m Ra (measured according to CLA method). …<??>By the application of such bands the efficiency of the driving belt increases. |
