Abstract

The tube is deformed at multiple locations distributed over the periphery between rolls rotating at the same peripheral speed and the mandrel, the rolls engaging the workpiece at such a small distance from each other that the free workpiece zones between successive rolls form non-deforming support areas which enclose the flow zones between the rolls and the mandrel in the peripheral direction.
