FIELD: material bending. SUBSTANCE: shaping of large-size facing is realized by two transitions. At first transition constant double curvature of facing is provided by action of bending loads in roll-type machine. At second transition facing is finally shaped for providing its variable double curvature by means of tension loads in stretching press. EFFECT: enhanced quality of facing due to their high accuracy without weakened portions and roughness of surface.
