ABSTRACT:
A worn, one-piece rail heated to a plastic state is initially deformed by a multi-stage rolling action to a slab constituted by flattened base and head extensions of an undeformed web portion of the rail. The slab is then edged in stages to effect thicknening of its intermediate portion and formation of a billet without any lapping, seaming or folding.
