FIELD: metallurgy.
SUBSTANCE: invention relates to metal forming and can be used for drawing from non-round sheet workpiece from aluminum alloy article in the form of beverage jar, balloon or aerosol can. Metal strip is virtually divided into identical workpieces in the form of regular hexagons, the perimeter of each of which is calculated proceeding from a concentric circle with radius less than the radius of the circle inscribed into the corresponding hexagon. At that, adding at least four feston in zones of hexagon at angles of almost 35°, 145°, 215° and 325° with direction of rolling.
EFFECT: higher quality of elongated article due to anisotropy compensation.
