Abstract (en)
[origin: DE19854481A1] A deformable distance ring (14) is placed on the forming mandrel (2). As the first workpiece (26) is being formed, an edge zone of this workpiece is pressed against the distance ring. The distance ring - which has been plastically deformed and strain-hardened - is left on the mandrel to assist forming of the subsequent workpieces.
