Abstract: A traction member for use with driving pulleys, consisting of one or more load-bearing elements and a plastics part which is arranged between the load-bearing elements and a force-transmission surface of the traction member. The overall friction value results from the fact that the force-transmission surface, which comes into contact with the driving pulley, has at least two regions, and that these regions are formed from different materials A and B having different coefficients of friction. The regions are in the form of strips in the longitudinal direction of the traction member. The carrier material A is softer and has a higher coefficient of friction and the further materials B1, B2, B3 etc. are each harder and each have a lower coefficient of friction. Preferably, the materials A, B1, B2, B3 etc. are applied in one work step by extrusion.
