FIELD: plastic working of metals. SUBSTANCE: method involves bending-in billet directed through a succession of passes by rolls, with cross shift of strip in first passes being restricted by roll rims. Portion of strip subjected to bending is in contact with upper roll. Rims of upper roll restrict shift of strip in terminating pass, with portion of strip subjected to bending being in contact with tool through rounded portion on lower roll. EFFECT: increased efficiency and high quality of bent bars by improved geometry of bars. 1 dwg
