Abstract (en)
[origin: EP0050483A1] In the melt-spinning of filaments, molten polymer is extruded downwardly through circularly arranged holes of a spinneret to from a circular group of filaments. Quench gas and finish liquid are directed outwardly through the filament group. In order to reduce vibration of the filaments as they pass from the spinneret to a lower guide, the filaments are passed through an upper guide which deflects the filaments inwardly towards the longitudinal axis defined by the filament group.
