PURPOSE:To reduce variance in the temp. distribution and quality of a finish rolled sheet bar and to obtain homogeneous products by automatically folding a stock rolled by a hot rough rolling mill into two and finish rolling the two-ply sheet bar. CONSTITUTION:A press roller 6 and the upper roll 4b of pinch rolls are moved up to wait. The top end of a sheet bar 2 on a delay table 3 is guided to the position of the upper roll 4b and the roll 4b is screw downed to fold the sheet bar 2 into two fold condition through the lower roll 4a of the pinch rolls and a rolling-over table 7. The pinch rolls 4a and 4b are reversely rotated to be synchronized with the table 3 to push out the two-fold sheet bar 2 to a finishing mill 17 side. The press roller 6 laps the two-fold sheet bar 2 into a two-ply condition. Then, the table 3, pinch rolls 4a, 4b, and roller 6 carry the two-ply sheet bar 2 and a press 9 presses the folded part flat and the bar 2 is carried to the mill 17 and is finish rolled.
