ABSTRACT Method of overlapping the edging passes of universally rolled shapes such as rails, beams and channels, as well as devices, rolls, stands and rolling mills to apply the method. An improved rolling mill for rolling rails from rail blanks includes an edger stand. The rolls of this stand are grooved and set to provide specific overlapped edging grooves having in common in an overlapped relation- ship a part of their bridging non-active shallow portions, the pass-line of at least one overlapped edging groove being transversely offset with respect to the single universal pass-line of at least a universal stand of the same universal-edger group as the edger stand. The rail blanks that are delivered along the single pass-line of at least a universal stand are deviated laterally towards an offset pass-line of an overlapped edging groove. The deviated rail blanks are taken over and guided into the offset pass-line of an overlapped edging groove. The rail blanks that are delivered along the offset pass-line of an overlapped edging groove are deviated towards the next single pass-line of a next-to-roll stand.
