Abstract

L'invention concerne un procédé et un dispositif pour le filage par fusion et le refroidissement d'une pluralité de monofilaments qui sont extrudés par une pluralité d'ouvertures d'une filière et guidés dans un bain de refroidissement. Pour l'étirage, les monofilaments sont déviés à l'intérieur du bain de refroidissement. Pour éviter un collage et un étirage en biais, les monofilaments sont divisés selon l'invention après l'extrusion en plusieurs groupes de filaments constitués de plusieurs monofilaments et les groupes de filaments sont déviés indépendamment les uns des autres à l'intérieur du bain de refroidissement dans plusieurs positions de déviation par des gaines de déviation respectivement séparées.
