Abstract

In an impact rolling apparatus the axes of roller heads are arranged substantially perpendicularly relative to the longitudinal axis of the workpiece. Accordingly, a displacing of the material at the workpiece proceeds predominantly tangentially perpendicularly to the longitudinal axis of the workpiece, caused by the impact effect of the impact rollers mounted at the roller heads. By this arrangement of the roller heads impact rolling operations can be performed close to a shoulder of the workpiece and marked steps thus maintaining the advantages over the known impact rolling method at which the displacement of the material proceeds predominantly in the direction of the longitudinal axis of the workpiece.
