FIELD: plastic metal working. SUBSTANCE: bars with local thickening of aluminium alloys with plating layer is produced from sheet blank by rolling in rollers for several passes, in course of which thickenings are formed for angle zones during the first pass, bending in profile, and forming thickenings on edges of blank with upsetting from end faces. Thickenings on edges are formed simultaneously with thickenings for angle zones during one process pass by upsetting and reduction in thickness of blank in roller inclined pass. In this case, angle of inclination of blank to vertical axis plane is selected from relation given in invention description. EFFECT: higher efficiency. 4 dwg
