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)

  1. 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.
  2. 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.
