Claims
- 1. An apparatus for guiding and transferring a rapidly quenched metallic tape comprising a cylindrical transfer guide for introducing thereinto and guiding therein the rapidly quenched metallic tape produced by solidification through rapid quenching on a circumferential surface of a single cooling roll and peeled therefrom, said transfer guide being arranged on a normal line of the single cooling roll at a position where the metallic tape is peeled, said transfer guide having upper and lower edges adjacent said single cooling roll and defining clearances with respect to said single cooling roll, a pinch roll unit arranged at a terminal end of the transfer guide for catching the metallic tape, and a transfer trolley for transferring said pinch roll unit to a winder for the metallic tape, said transfer guide is arranged adjacent said single cooling roll, and the apparatus further comprises an air knife for peeling the metallic tape from the single cooling roll by air jetting, said air knife being arranged extending from a downstream side of a rotating direction of the single cooling roll toward said upper clearance between the single cooling roll and the transfer guide, and an adjusting plate on said transfer guide for adjusting the upper clearance between the single cooling roll and the transfer guide.
- 2. An apparatus as set forth in claim 1, wherein said apparatus further comprises a suction blower arranged downstream of said pinch roll unit for producing high speed air flow in the transfer guide, a tachometer for detecting rotating speeds of the single cooling roll, and a speed meter for detecting velocities of the high speed air flow in the transfer guide.
- 3. An apparatus as set forth in claim 1, wherein said transfer guide has a length between 10 cm-100 cm.
- 4. An apparatus as set forth in claim 1, wherein said apparatus further comprises a blower for guiding the metallic tape to the pinch roll unit by suction air produced by the blower, and a deflector roll provided on an entrance side of the transfer guide to form a pass line for the metallic tape, and there is provided a clearance between the deflector roll and a bottom plate of the transfer guide for causing air to flow into the clearance by suction air of the blower.
- 5. A method of guiding and transferring a rapidly quenched metallic tape which comprises the steps of, peeling 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, jetting air through an upper clearance between the cooling roll and a cylindrical transfer guide, controlling the size of said clearance to adjust the amount of the jetted air against the peeled tape to support and feed the tape to avoid contact with said cylindrical transfer guide, introducing the peeled metallic tape into said transfer guide arranged in a flying direction of the metallic tape to feed the metallic tape substantially without being in contact with the transfer guide, guiding said metallic tape by suction air to a pinch roll arranged at a terminal end of the transfer guide, said suction air being developed by means of a blower, in which high speed air flow directing from an entrance side to a delivery side of the transfer guide is caused by air suction on the delivery side of the transfer guide so that the velocity of the metallic tape fed in the transfer guide, to catch the metallic tape by a pinch roll unit along a pass line substantially formed by a deflector roll with an air floated provided on the entrance side of the transfer guide, and moving the pinch roll unit to a winder for winding the metallic tape.
- 6. A method as set forth in claim 5 including adjusting the flow rate of the high speed air flow by at least one of adjustments of an amount of the air suction on the delivery side of the transfer guide, and adjusting the amount of the air jetting for peeling the rapidly quenched metallic tape and adjusting the clearance between said cooling roll and the transfer guide.
- 7. A method of guiding and transferring a rapidly quenched metallic tape, comprising the steps of peeling a rapidly quenched metallic tape from a cooling roll, by directing an air stream through a clearance between an upper edge of a transfer guide and said cooling roll for deflecting said peeled metallic tape upwardly a predetermined amount to define a pass line extending midway through said transfer guide, adjusting the size of said clearance to control the amount of said air stream, directing said peeled metallic tape to a transfer guide by means of air flow, guiding said peeled metallic tape to a pinch roll by means of suction developed at the terminal end of said transfer guide, said suction being higher than the air flow at the entry to said transfer guide, said pinch roll being positioned along said pass line, deflecting said moving metallic tape toward said pinch roll, and moving said pinch roll toward a winder, and winding said metallic tape.
