In the stretch-straightening process the product to be straightened is subjected to a tensile force. This results in a tensile stress inside the workpiece, which superimposes on the existing internal stresses.
The tensile force is applied in sections and at a level of magnitude designed to produce plastic deformations in the material to be straightened.
