FIELD: plastic working of metals, possibly rolling out outer surfaces of parts.
SUBSTANCE: apparatus includes housing, two double-arm levers with rolling out heads, strengthening rollers and mechanism for controlling rolling out effort. One of rolling out heads includes two strengthening rollers and it is secured to double-arm lever with possibility of rotation in axle; its rotation center is arranged diametrically opposite relative to rotation center of strengthening roller of rolling out head mounted in other double-arm lever.
EFFECT: elimination of efforts acting upon rest of lathe and upon part, improved quality of surface.
