摘要：
A cold rolling method and apparatus for forming an annular workpiece (10) with an outer surface (11) having a given contour and an inner surface (12) having a given contour, starting from an annular blank. A rotatable forming mandrel (21) has a working surface (21a) with a contour corresponding to that of inner surface (12) to be formed. A forming die (51) has a cavity (52) with an inner working surface (53) in form of a surface of revolution corresponding to the outer surface (11) to be formed.
