FIELD: plastic metal working; possibly, production of long shaped articles of minor curvature. SUBSTANCE: device containing two pairs of feed rollers is provided with rotary ramp mounted for rotation about vertical axis with bending bevel cams located on the axis and made in the form of inclined cylinders, which are installed for synchronous rotation about vertical axes running through centers of lower bases of cylinders; in so doing one of the bending bevel cams is placed for reciprocating rotary motion towards another cam. EFFECT: production of shaped articles of single as well as reversed curvature with variable bevel over length of shape. 3 cl, 4 dwg
