Abstract
In a take-up apparatus for an amorphous metal ribbon a first tubular guide provides a passage for the ribbon from a ribbon manufacturing apparatus. A storage chamber is connected to the first tubular guide and a take-up drum is connected to the storage chamber through a second telescopic tubular guide. A gas suction device is connected to the take-up drum through a third tubular guide. The take-up apparatus is arranged in tandem with the ribbon manufacturing apparatus which comprises a crucible equipped at its lower end with a nozzle and accommodating a molten metal therewithin and a rapidly rotating quench roll disposed below the nozzle. The ribbon is manufactured by rapidly quenching the molten metal ejected from the nozzle on the quench roll and removing the ribbon at a high speed in a direction tangent to the quench roll. The ribbon is then sucked into the first tubular guide together with an air flow provided by the gas suction device.
