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.

Straightening jaws for a straightening device for straightening wire, comprising:
- a chuck comprising a first end and a second end, wherein said first end comprises a straightening groove having an intake element and an exit element and a cylindrical opening between the intake element and the exit element that runs perpendicular to the first end;
- and
- a straightening insert inserted into said opening and said straightening insert is held positively on all sides in said chuck with play, wherein said straightening insert has an end with a saddle-shaped straightening indentation that connects said intake element with said exit element.
A straightening insert for use in a straightening jaw comprising:
- a cylindrical form having a first end;
- a saddle-shaped straightening indentation on said first end;
- and
- a locking device for preventing relative rotation with respect to a chuck, wherein said straightening inset has a non-circular, nearly constant cross-section.
Straightening jaws for a straightening device for straightening wire, comprising:
- a chuck comprising a first end and a second end, wherein said first end comprises a straightening groove having an intake element and an exit element and a prismatic opening between the intake element and the exit element that runs perpendicular to the first end;
- and
- a straightening insert inserted into said opening, wherein said straightening insert has an end with a saddle-shaped straightening indentation that connects said intake element with said exit element, wherein said straightening insert is held positively on all sides in said chuck with play.
A straightening insert for use in a straightening jaw comprising:
- a prismatic form having a first end;
- a saddle-shaped straightening indentation on said first end;
- and
- a locking device for preventing relative rotation with respect to a chuck.
A straightening device for straightening a wire, comprising:
- a straightening body having a straightening channel wherein said wire is inserted therein and wherein said channel is defined by a straightening jaw;
- said straightening jaw comprises a chuck, wherein said chuck comprises a first end and a second end, wherein said firs tend comprises a straightening groove having an intake element and an exit element and a prismatic opening between the intake element and the exit element that runs perpendicular to the first end;
- and
- a straightening insert inserted into said opening so that said straightening insert is held in said chuck with play, wherein said straightening insert has an end with a saddle-shaped straightening indentation that connects said intake element with said exit element.
A straightening device for straightening a wire, comprising:
- a straightening body having a straightening channel wherein said wire is inserted therein and wherein said channel is defined by a straightening jaw having a chuck;
- said straightening jaw comprises a straightening insert, wherein said straightening insert comprising a prismatic from having a first end, a saddle-shaped straightening indentation on said first end, and a locking device, independent of said chuck, for preventing relative rotation with respect to said chuck.
