Abstract

L'invention concerne un procédé de production d'un rail comprenant un champignon du rail, un patin du rail et une âme du rail qui raccorde le champignon du rail au patin du rail, caractérisé en ce que le champignon du rail (2) et/ou le patin du rail (3) et/ou une âme unique du rail (1) ou une âme unique du rail (1) qui raccorde le champignon du rail (2) au patin du rail (3) est enroulé(e) de sorte que dans le plan transversal du rail, on obtienne une longueur de l'âme unique du rail (1) supérieure à la distance entre la surface (14) du champignon du rail (2) et la surface (15) du patin du rail (3) qui se font face, de préférence supérieure à la distance minimale entre la surface (14) du champignon du rail (2) et la surface (15) du patin du rail (3) qui se font face.
