Of the present invention, in that by using a take-up device having a plurality of take-up roll magnetically to the surface winding the amorphous alloy thin ribbon, and easy and also inexpensive, regardless of the volume chwiryang, either breaking of the thin ribbons, winding deviation, etc. by providing a stable take-up winding of the amorphous thin ribbon for realizing the switching of the roll the roll changer and method without problems, in the method of winding the amorphous sheet having a cast magnetic using a cooling roll using the two or more take-up rolls, when switching the take-up roll is brought into contact with an amorphous thin plate in the following winding roll, but also by cutting the amorphous thin plate being wound in a state in which the proximity of the following take-up roll on the cooling roll or the separation of the following take-up roll and a chill roll take-up roll and between the winding roll and then characterized in that for cutting the amorphous thin plate, the switching method of the amorphous sheet. Magnetic winding rolls, broken, amorphous thin cooling roll
