摘要： The invention concerns a method for manufacturing metal rings (41) for a drive belt (3) comprising a laminated set (31 ) of such metal rings (41), wherein the rings (41 ) are formed by cutting (IV) these from a tube (22) and wherein the cut rings (41 ) are rolled (V) to reduce their thickness, while increasing their length. According to the invention, the process step of cutting (IV) the rings (41) from the tube (22) is arranged to vary the width of a ring (41) cut from the tube (22) in relation to, in particular, a wall thickness of the tube (22) before cutting (IV).

摘要： The invention concerns a method for manufacturing a metal ring (41) for a ring set of a drive belt for a continuously variable transmission, wherein the metal rings (41) are individually extended in their circumference direction, while their thickness is being reduced, in a rolling process step. After rolling, the metal rings (41) are processed further and a number of thus processed metal rings (41) are mutually nested to form the ring set. According to the invention, after the said number of metal rings (41) have been rolled, but before these are nested to form the ring set, some of the metal rings (41; 41b) are either turned inside out or are rotated about their radial direction for a half rotation in a novel, additional process step (APS) and some of the metal rings (41; 41a) are not.

摘要： The invention relates to a drive belt (3) including an endless carrier (31) and a plurality of transverse members (32) of varying thickness, i.e. of varying dimension measured in the circumference direction "L" of the belt (3), which transverse members (32) are provided with a rocking edge (18) in the form an axially and radially extending section of a respective main body surface (38; 39) of the transverse member (32) that is convexly curved in radial direction. According to the invention, the design of such drive belt (3) can be improved, at least in terms of durability, by shaping the rocking edge (18) of the thinner transverse members (32) of such drive belt (3) according a larger radius of curvature in comparison with the radius of curvature of the rocking edge (18) of thicker transverse members (32) thereof.
