Abstract

The apparatus comprises a permanent or electromagnet whose fixed or adjustable poles or cores are in alignment with or concentric to a central pole. The magnetic fields permit the apparatus to be supported on the part to be straightened by manual or mechanical traction or pressure. In the event of thin workpieces, straightening is by attracting the concave part of the deformation with or without the employment of suitable stress. The inserted tips of the movable poles or cores of the electromagnet operating on a.c. or d.c. current ensure manual or automatic impulses on the metal surface in the manner of hammering.
