FIELD: metal forming.
SUBSTANCE: invention relates to metal forming, particularly, to straightening of metal flat product by bending pressing or combination of straightening with bending pressing. Performing bending pressing or combined straightening in bending device containing multiple interacting correct rolls. At that, each of at least two interacting regular rolls comprises at least three rollers, which are located next to each other in axial direction and are made with possibility of their separate adjustment.
EFFECT: separate adjustment of rollers allows to improve quality of metal product due to elimination of flatness error.
