Abstract

The straightening jaw comprises a cubical chuck with a plane face end. The face end has an intake element and an exit element of a straightening groove. Between them is an opening arranged perpendicular to the face end. A straightening insert made of hard metal is inserted into the opening loosely but insured against twisting. On the face end, the straightening insert has a of saddle-shaped straightening indentation that connects the intake and exit elements. Because of this structure, long service lives of the straightening jaw and shorter down times of the straightening device causing low production costs are achieved.
