Roll heading for handling metallic workpieces, has main part which forms an angle of incidence with holder as holder rotates, and supporting part which forms angle of incidence with holder to rework edge of workpiece

摘要

A turnable holder (6) is stored between a main part (7) and a supporting part (8) such that a workpiece is adjustably held with respect to the rotating axis (D) around which the holder turns. The main part forms an angle of incidence with respect to the edge of the workpiece during actual rotation. The supporting part forms an angle of incidence with the holder to rework the edge of the workpiece.
