1. A plate-link chain for a conical disk transmission having a steplessly adjustable transmission ratio, said chain comprising: a plurality of interconnected chain links to define a multiple-link chain, individual chain links of which are formed from plate link sets that are connected as pairs by rocker members that are inserted into openings in the plate links and that have rocker faces that are supported against each other for relative rolling movement, wherein the plate-link openings have a different plate-link opening inner width based upon the position of a link in the direction of the chain width, wherein the plate-link openings initially have equal plate-link opening inner widths and are produced by a stamping process, and wherein the stamped plate links are stretched to provide plate links having different opening inner widths and are assembled together with respective rocker members to provide the chain links. |
