Abstract: PROBLEM TO BE SOLVED: To avoid coil telescoping and to improve productivity by detracting the meandering quantity of the strip metal on the outlet side of a magnet conveyor and making the magnet conveyor move in the direction perpendicular to a transfer line according to the meandering quantity. SOLUTION: After cutting by a shear 8, the tip province of the strip S becomes a nontension state, when the strip S is transferred onto the magnet conveyor 1 while it is shifted from the transfer line, the tip of the strip metal S is attracted onto a belt 1a by an electromagnet 1c. When the strip metal S reaches the outlet side of the conveyor, the measuring quantity (shift quantity) of the strip metal S is detected by an image sensor 3. According to the detection, a common base 4 is moved along a rail 6 until the center of the strip metal S and that of the transfer line coincide. In the same way, after the revolute of the coil is cut by a shear, even when the coil reaches the conveyor while it meanders, meandering is straightened by the method.
