Abstract

Procédé et dispositif de filage en continu de polymères thermoplastiques en fusion. Dans le dispositif de filage en fusion selon la présente invention, toute la filtration est effectuée avant la pompe de distribution 26 alimentant la filière 44 en utilisant des filtres 22, 24 en alternance, comme cela est connu et un moyen destiné à créer une résistance à l'écoulement 46 relie la pompe de distribution à la filière. Application à un dispositif de filage en fusion pouvant fonctionner en continu, indéfiniment, sans interruption pour le changement de filtre.
