Abstract
Procédé et laminoir pour obtenir des profilés à partir de rails de chemin de fer. Au plus tard dès la troisième passe on refoule l'âme du rail dans le sens de son axe principal en la soutenant entre deux galets latéraux, et on pratique en alternance avec la ou les passes de refoulement de l'âme des passes refoulant le patin et le champignon en cannelures roulantes. L'invention permet d'obtenir des profilés variés sans passer par une section intermédiaire classique.
