A method of guiding and transferring a rapidly quenched metallic tape includes steps of peeling the rapidly quenched metallic tape produced by solidification through rapid quenching on a circumferential surface of a single cooling roll rotating at a high speed, introducing the metallic tape into a cylindrical transfer guide to a pinch roll unit arranged at a terminal end of the transfer guide to catch the metallic tape by the pinch roll unit, and moving the pinch roll unit to a winder for the metal tape. The metallic tape is fed in the transfer guide substantially without being in contact with the transfer guide. An apparatus for guiding and transferring a rapidly quenched metallic tape includes a cylindrical transfer guide arranged on a normal line of a single cooling roll for introducing and guiding the metallic tape, a pinch roll unit arranged at a terminal end of the transfer guide for catching the metallic tape, and a transfer trolley for transferring the pinch roll unit to a winder for the metallic tape.

Apparatus for transferring rapidly quenched metallic tapes

An apparatus for transferring a rapidly quenched metallic tape, which is produced by solidification through rapid quenching on a circumferential surface of a single cooling roll rotating at a high speed, from the cooling roll into a winder, comprises a transfer means provided with a pinch roll unit for catching and feeding out the peeled metallic tape, a fan for breaking and discharging the metallic tape fed out from the pinch roll unit, and a dust device for recovering metallic pieces and powder generated in the breakage of the metallic tape by the fan.

A method and an apparatus for transporting a rapidly quenched ribbon from a cooling roll to a winding reel by a pinch roll are disclosed. The pinch roll comprises a brush roll and a solid roll for transporting the ribbon such as to maintain an adequate tension in the ribbon without any transversal displacement and breakdown of ribbon. The tension is controlled within a range of 2.about.8 kgf by adjusting at least one of an amount of pressing of the brush roll against the solid roll, a pressing force on the brush roll and a ratio between circumferential speeds of the pinch roll and the cooling roll.
