ABSTRACT:
A method and apparatus for quenching synthetic filaments such as synthetic yarn filaments as they exit a plurality of openings in an extrusion die in a downward direction and in an annular pattern. A quenching head is provided with quenching gas from a source, and the quenching head includes first and second nozzles which are disposed adjacent and beneath the extrusion die and within the annular pattern of filaments, and each of the nozzles is formed to cause the quenching gas to pass therefrom generally radially toward the annular pattern of filaments and at a predetermined angle directed upwardly with respect to a horizontal plane through the nozzle to provide a more uniform quenching of all of the filaments in the annular pattern.
