Abstract

L'invention concerne un procédé et une installation de filage par fusion et de découpage d'un câble de filaments pour produire des fibres discontinues. Selon l'invention, une pluralité de filaments sont filés au moyen d'un dispositif de filage et assemblés pour former un câble de filaments. Après plusieurs traitements dans plusieurs dispositifs de traitement, ce câble de filaments est découpé lors d'un processus continu après l'opération de filage pour former des fibres discontinues. Dans un des dispositifs de traitement, le câble de filaments est guidé et étiré par l'intermédiaire de plusieurs cylindres d'étirage, ledit câble de filaments étant traité avec un fluide sur une ligne de traitement formée entre des cylindres d'étirage. Pour réduire en particulier le problème de l'irrégularité des propriétés physiques des fibres lors d'un processus en une étape, le câble de filaments est traité à la vapeur. A cet effet, le câble de filaments est guidé sur une ligne de traitement entre des cylindres d'étirage à travers une chambre à vapeur dans laquelle débouche une buse qui introduit la vapeur en surpression dans la chambre à vapeur.
