Abstract
A melt spinning apparatus is disclosed which includes a spinning nozzle for extruding a plurality of filaments from a polymeric melt, and which includes a spinning tube positioned below the nozzle for receiving the filaments. The upper end portion of the spinning tube is perforated, and an air blowing chamber surrounds the perforated upper end portion of the tube for supplying cooling air, and so that the air passes through the perforations to cool the filaments. The interior of the perforated end portion of the spinning tube also mounts a plurality of annular rings which are disposed in an axially spaced apart relation along the length of the end portion, for guiding the cooling air so as to flow in a generally radial direction into contact with the extruded filaments.
