FIELD: drawing production, namely, manufacture of rods and wire with rectangular cross section in roller drawing dies. SUBSTANCE: rectangular cross-section blank is deformed in two rollers with flat working surfaces. Leading end of blank is slandered at simultaneously lowering size of less side of blank cross section. At guiding blank is arranged in such a way that large sides of its cross section are arranged in parallel with axes of rollers.
