Abstract
An apparatus for producing a synthetic filament yarn including a spinneret and cooling shaft. A plurality of air deflecting members in the form of coaxial tubes or flat plates are mounted within the cooling shaft so that the upper edge of each tube or plate lies closely adjacent the periphery of the bundle of extruded filaments, and the lower edge of each tube or plate is at a distance from the filaments greater than that of the upper edge. The deflecting members thus serve to shield the filaments from air turbulence and also to remove from the filaments a significant portion of the heated air which is entrained with the advancing filaments.
