Abstract: Method and device (10) to obtain in the hot state single finished round bars (12a-112a) from hot single multiple elements (11), wherein the device (10) cooperates with at least a penultimate finishing stand (25) and cooperates directly with rolls (26) of that finishing stand (25) and with generating profiles included in that stand (25) and comprises means to displace vertically and reciprocally the plane of positioning of each single bar (12a) forming the central part of the multiple element, and also comprises means to displace sideways on the plane of positioning at least the single outermost lateral bars (112a) of the multiple element (11) , and further comprises upstream guiding system means (20) and mating wheel means (21-121) which define separation passes (13) and contain at least one lateral edge with a lateral wedge-shaped bevel (15).

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.
