Abstract
A method to roll multiple sections starting from a single round section, comprising the steps of: (a) passing the single round section between the rolls of a rolling mill to obtain a single bar including two substantially elliptical, united, twin sections, the major axes of the elliptical sections being inclined by an angle ranging between 5.degree. and 30.degree. in relation to an axis normal to the axes of the rolling rolls; and (b) passing the single bar including two substantially elliptical, united, twin sections between the rolls of a rolling mill to obtain twin-strand round sections.
