PURPOSE:To prevent a metallic band from turning aside in winding and rewinding the metallic band of a coil which is put on two rolls, by driving the roll placed on the downstream side in the advancing direction of the band, and stopping the driving of the roll placed in the upstream side. CONSTITUTION:A coil C of metallic band is put on cradle rolls R1 and R2, and a metallic band S is rewound. At this time, a motor M rotates in the A direction; the roll R2 is made idle by making the load on a cam clutch 2 OFF, and by making the load on a cam clutch 1 ON, a rotatively driving force of the motor M is transmitted to the roll R1 and the band S is rewound by the coil C. At the time when the band S is wound by the coil C, the motor M rotates in the B direction; the cradle roll R1 is made idle by making the load of the cam clutch 1 OFF, and by making the load of the clutch 2 ON the rotatively driving force of the motor M is transmitted to the roll R2 and the band S is wound by the coil C. |
