VERFAHREN UND VORRICHTUNG ZUR AUSBILDUNG EINES ASYMMETRISCHEN KOERPERS MITTELS EINES WALZVORGANGS

摘要

A pair of dies are provided of which die faces are formed with depressions sequentially brought into engagement with a particular portion of a workpiece as the workpiece rolls between the die faces. By compressing the workpiece while driving the same to roll between the die faces, an excess metal of the workpiece is caused to flow into the depressions sequentially for thereby forming an asymmetrical part of the article.
