Abstract (en)
Process and apparatus for melt spinning filaments, the process comprising extruding molten polymer downwardly through a fibre pack (12) and a spinneret (14) and quenching the filaments (16) with a gas, in which the quenching gas for cooling the filaments (16) is supplied through a conduit (24) extending through the pack (12) and the spinneret (14). In a preferred process, a finish substance is applied to the quenched filaments, such finish substance having been supplied through a conduit (40) located within the conduit (24).
