During winding, particularly at the beginning of casting, the ribbon 6 may be broken due to a defective portion of the ribbon 6 or the like. When broken, the ribbon 6 on the circumferential surface of the cooling roll 11
Is not peeled off, and reaches the casting nozzle 6 and damages the equipment. Therefore, a gas nozzle 13 is provided as shown in FIG. 1, and the strip 6 after being broken is peeled off from the circumferential surface of the cooling roll 11 and removed. Casting is stopped by the dish stopper 10.

る。In order to transfer the tip of the ribbon 6 from the circumferential surface of the cooling roll 11 to the winding roll 12, a permanent magnet, which is separated by a gas nozzle and adhered to the circumferential surface of the winding roll 12, is used. An adsorption method of adsorbing to a take-up roll 12 made of, for example, is employed. The latter is the case where the ribbon 6 is a magnetic material. When the ribbon 6 breaks during the winding as described above, the winding method cannot be performed after the winding of the winding roll 12 exceeds one winding by the bonding method. In the suction method, it is impossible to wind up after being wound to a thickness beyond magnetic force.
