Abstract
A plurality of annular clutch disks () is manufactured by blanking or die-cutting a flat sheet metal strip () during which the flat sheet metal strip () is advanced relative to a blanking or cutting tool along a feed direction between individual blanking or cutting processes with the blanking or cutting tool in order to form the annular clutch disks () from the flat sheet metal strip (). Each of the annular clutch disks () is asymmetric with respect to a center point of a respective ring and includes an axis of symmetry () which is not orthogonal to the feed direction of the flat sheet metal strip. Each of the annular clutch disks () is axially symmetric at least to such an extent that each of the annular clutch disks () is installable in a multi-disk clutch () in precisely one first installation position (A) and in one second installation position (B). The second installation position results from the first installation position via turning over about the axis of symmetry ().
