This supporting and drive means (11) has the geometry of a belt consisting of a belt body (12) or sheathing (12) which encloses the tensile carriers (1). The running surface (16) of the belt can be flat and parallel to the belt back (13) or have trapezium- shaped or semicircular ribs (14) and grooves (15), wherein the profile of a drive pulley or of a deflecting pulley is approximately complementary to the running surface of the belt. One or more tensile carriers (1) are provided for each rib (14), wherein the tensile carriers (1) are laid or stranded alternately in Z direction and S direction.
