Одним из путей увеличения производства арматуры на действующих станах в кратчайший срок без серьезных капитальных вложений является использование технологии прокатки  –  разделения. Приведены условия осуществимости успешной реализации процесса прокатки – разделения. Получены новые зависимости для определения продольной силы, обеспеченной резервом сил трения при формировании сочлененного профиля, которые учитывают форму профиля и условия формоизменения.</p></abstract><trans-abstract xml:lang="en"><p>The emerging growth of industrial and civil construction in Russia and introduction of new technologies have caused the need to increase the production of construction rolled products and, especially, rebar. One of the ways to increase rebar production at existing mills in the shortest possible time without serious capital investments is the use of rolling – separation technology. For successful implementation of this technology, the conditions for the feasibility of this process are given in this report. New dependences were obtained for determining the longitudinal force provided by the reserve of friction forces during formation of an articulated profile taking into account the profile shape and the conditions of shape change.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прокатка – разделение</kwd><kwd>условия осуществимости</kwd><kwd>сочлененный профиль</kwd><kwd>продольная сила</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rolling – separation</kwd><kwd>feasibility conditions</kwd><kwd>articulated profile</kwd><kwd>longitudinal force</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Brown V.L, Bartholomew C.L.
