Abstract
Several extruded filaments are withdrawn from the extrusion nozzles by a super-sonic air flow and are fed through a guide tube, which abruptly increases in diameter at mid-section, towards a divergent outlet nozzle from which they are deposited on a conveyor in the form of a web. The air velocity which is always greater than the filament specif. reduces abruptly to subsonic flow during its passage through the guide tube, which pref. comprises a small diameter tube engaged within a larger tube the diameter ratios of the tubes being pref. between 0.5-0.8. Air may be vented from the guide tube via a lateral aperture upstream of the nozzle. The appts. can run at high speeds and the necessity of electrostatically charging the filaments to achieve intermingling is eliminated.
