ABSTRACT:
Apparatus for automatically straightening portions of a rod assembly having stubs extending outwardly from a yoke connected to the end of a rod and which is used in the electrolytic production of metals. A bent portion of the rod portion of the assembly is straightened by opposing anvils adapted for movement toward one another. As the anvils are closed together, a bent rod portion between them is straightened. The stubs which become toed-in during use are straightened by a stub straightening portion of the apparatus which is inserted between the stubs and actuated against the stubs with sufficient force to remove the toe-in. The apparatus is adapted to perform the straightening automatically on bent rod assemblies which are transported through the apparatus.
