PURPOSE:To decrease the floor area of equipment and to decrease the number of rolling mills by moving the molding machine directly coupled to the rolling mill back and forth along the progressing direction of a work and changing the roll gap of the molding machine in correspondence to the position and moving direction of the molding machine. CONSTITUTION:A blank 2 is continuously rolled by the rolling mill 3 directly coupled to a continuous casting machine, injection molding machine or extruder 1 and is rolled to a prescribed sectional shape by the molding machine 4. The molding machine 4 is movable back and forth in arrow directions 5, 6 along the progressing direction of the material 2. Rolling is executed while the gap (y) of non-driven roll sets 7, 7' of the molding machine 4 is changed according to a prescribed pattern in correspondence to said moving direction 5 or 6 and the moving position (x) of the molding machine 4. The loci drawn by revolving shafts 9, 9' of the molding rolls are A1, A1' and (y) decreases with an increase in (x). The roll gap (y) is then increased and the molding machine 4 is moved backward. The same point of the blank is thus rolled many times by one unit of the molding machine.
