FIELD: plastic metal working. ^ SUBSTANCE: according to propose invention, at continuous longitudinal feeding of wire, cross rolling is done by pair of rollers clearance between which is made narrowing in direction of wire feeding. Each roller of pair is set into rotation in one direction, while pair of rollers is turned relative to axis of wire in opposite direction. In process of wire feeding it is expedient to twist the wire relative to its axis. Invention provides deformation limited only by plasticity properties of wire material. Proposed method makes it possible to produce fine and superfine wire. ^ EFFECT: increased deformation of wire at one pass on one device. ^ 2 cl, 2 ex, 7 dwg |
