Abstract
A material, such as metal, is passed along a rolling mill train to produce a profiled support or rail. At certain stages the passage of the material is reversed so that the material passes through certain rolling stands more than once. The train comprises the following stands: a reversing pre-rolling stand; an edging stand; and a reversing universal rolling stand. After a return passage through the reversing universal rolling stand, the caliber rolls of the edging stand are reduced and the material passes again twice through the edging stand and the reversing universal rolling stand.
