Abstract

Filière résistant à la corrosion, utilisable notamment pour filer des filaments de poly (p-phénylène téréphtalamide) à partir d'une solution acide. Une couche de 0,6 à 1 mm de tantale pur du commerce 14 est liée par explosion à une plaque d'alliage de tantale ou d'acier inoxydable 12 traversée par un alésage 16 qui se termine dans la couche 14 par un fond conique 26 prolongé par le capillaire de filière 28. Application à l'industrie textile.
