3, when the load signal is input to the load cell 8 provided in the rolling mill 2, when the load signal is input, the cylinder 7 is connected to the arm 6 via the control device (not shown). Has been sucked, the pinch roller 5 has risen and is separated from the rolled material 1. FIG. 1 shows this state. As shown in FIG. 2, when the rolled material 1 separates from the rolling mill 2 and slips off, the load signal of the load cell 6 turns off. At this time, the cylinder 7 pushes the arm 6 downward and the pinch roller 5 rolls the rolled material. 1, the rolled material 1 is held together with the looper 4 to apply rearward tension. In this state, the rolled material 1 is detected by detecting the load difference between the left and right of the rolled material 1 described in the case of the conventional example.
It is possible to prevent the meandering. FIG. 3 is a time chart showing the above-mentioned operation.
