FIELD: metallurgy, production of band type rolling products. SUBSTANCE: in process of band cold rolling surface of one of finish stand operational rolls is made in the form of girdling ring grooves and rest part of roll surface is cut by split shots, that allows to produce on surface of rolled band bulges of definite form of their cross-section and dimensions: width, height and step between bulges. Surface of second operational roll is cut only by split shots. After recrystallized annealing of the way produced band it is stretched with tension by rolling mill stand stretching stations by 50 - 80 % of band material tensile strength limit and bulges on band are rolled flat in preliminary stretched band compensating for tension in places of rolled in band bulges. EFFECT: improved process. 2 dwg
