Abstract

L'invention concerne un dispositif de filage à l'état fondu pour la fabrication de fils synthétiques pourvu d'une pluralité de positions de filage. Chacune des positions de filage comprend un système de filière, un système de refroidissement, un système de galettes et un système d'enroulement. Pour placer les fils dans les positions de filage, une commande automatique peut être amenée à chacune des positions de filage pour placer les fils. L'invention vise à obtenir un guidage fiable et un positionnement précis pour placer les fils. Le système de guidage est à cet effet formé par un convoyeur aérien, sur lequel la commande automatique est guidée. La commande automatique est maintenue de manière stationnaire dans les positions de filage respectivement par un moyen de blocage pouvant être commandé à l'intérieur du convoyeur aérien.
