Abstract

L'invention concerne un procédé pour produire des profilés creux présentant, sur leur longueur, des sections transversales différentes. Ces profilés sont formés dans une matrice à partir d'une seule pièce de tôle plate découpée (5, 6, 7). Selon l'invention, un arrondissage convexe ou concave réalisé au niveau des arêtes de coupe longitudinales (8a, 8b, 9a, 9b) provoque un excédent ou un déficit de matière dans les zones de jonction, ce qui permet d'éviter, lors du formage, l'apparition d'épaississements ou d'amincissements de matière dans les zones de jonction (8, 9).
