ABSTRACT:
An apparatus for extruding molten polymeric material into a plurality of filaments. The apparatus includes a pack which has a distribution plate and a circular spinneret positioned below the distribution plate. A quenching head is carried within and below the circular spinneret and includes a plurality of concentric hubs carried on a cylindrical tubular main body. Each of the concentric hubs has an upwardly inclined wall adjacent an upper portion of the hub which defines an incline annular passage which extends upwardly towards the spinneret through which quenching air is fed from the cylindrical tubular body through the passages for cooling the filaments being produced by the spinneret.
