Abstract

L'invention concerne un procédé et un dispositif de fabrication de fils multifilaments fins à partir d'une masse fondue de polymère. Une pluralité de filaments sont extrudés, refroidis et réunis en faisceaux formant chacun un fil respectif. Les fils sont étirés par plusieurs galettes et enroulés en bobines. L'objet de l'invention est d'obtenir un guidage stable des fils, y compris lorsque les fils présentent un titre très fin. À cet effet, selon l'invention, les fils sont réunis en plusieurs faisceaux de fils avant d'être étirés. Les faisceaux de fils sont guidés parallèlement les uns aux autres sur les galettes et étirés, et, une fois étirés, à nouveau séparés en fils individuels. À cet effet, un guide-fil de faisceau est situé du côté de sortie d'un dispositif d'étirage.
