Definitions
- the dimensions of the duct system are given in detail together with the process parameters.
- the channel system ended at the drum circumference of a centrifuge in which the thread formed was deposited. The thread was then washed out for decoupling and any customary aftertreatments were then carried out in the centrifuge.

Claims (2)
- Procédé pour le formage de fils, de fils creux, de feuilles extrudées à plat ou en gaine et de produits similaires (tubes, plaques) réalisés à partir de matériaux formant des fils, constitués d'un système polycomposants liquide, homogène, isotrope ou anisotrope, à une ou plusieurs phases, le système poly-composants liquide étant injecté à travers un ou plusieurs orifices de buse dans un liquide éventuellement chauffé ou refroidi qui se trouve à une pression excessive ledit liquide étant mis en mouvement dans la direction de marche du fil dans un système de canaux composé de tronçons à section constante et/ou faiblement décroissante et la vitesse d'écoulement du liquide augmentant en conséquence, caractérisé par le fait que l'on règle la pression dans le liquide, en-dessous de la buse, à une valeur de 2,5 - 250 bars et qu'on l'abaisse le long du système de canaux jusqu'à la pression atmosphérique et par le fait que la vitesse du liquide à la sortie du système de canaux est réglée à une valeur inférieure à celle du système poly-composants.
- Procédé selon la revendication 1, caractérisé par le fait que l'on abaisse la vitesse d'écoulement du liquide à l'extrémité du système de canaux dans un diffuseur.
