FIELD: process engineering.SUBSTANCE: invention relates to metal forming, particularly to continuous bending with drawing of metal strips under extension strains below elastic limit that mutually bend in plastic or elastoplastic range around, at least, four straightening rollers and are subjected to plastic extension. Note here that radii of bending at all four straightening rollers are adjusted separately and independently. Note also that straightening rollers are set separately with adjustment of the position.EFFECT: higher flatness, simplified design.29 cl, 4 dwg |
