Patent ID: 8235091

Claim:
An amorphous ribbon switching system in a take-up device, said take-up device comprising two or more take-up rolls having magnetized surfaces for taking up a magnetic amorphous ribbon cast on a cooling roll, wherein at any given time a current take-up roll of said two or more take-up rolls is taking up amorphous ribbon and a next take-up roll of said two or more take-up rolls is not taking-up amorphous ribbons, said amorphous ribbon switching system comprising: a cutting mechanism adapted to bring said next take-up roll into contact with the amorphous ribbon at a location between said current take-up roll and said cooling roll and then cut the amorphous ribbon; and a guide device comprising a guide roll and a guide plate disposed in proximity to the next take-up roll, wherein the guide roll is adapted to press a cut tip of the cut amorphous ribbon against the magnetized surface of said next take-up roll in a circumferential direction to prevent a folded back part of the cut tip from bulging out, and the guide plate is adapted to press the amorphous ribbon against the next take-up roll to guide the pressed amorphous ribbon to an engagement part of the amorphous ribbon.
