Abstract

On forme des éléments filtrants tubulaires en alimentant d'abord une suspension épaisse de fibres dans un espace de moulage tubulaire 42 compris entre un noyau vertical 43 et un treillis cylindrique à fines mailles 44, de l'air sous pression est alimenté à cette suspension de manière que le liquide s'égoutte à travers le treillis 44 et à travers un treillis 46 prévu à la base de l'espace 42, tandis qu'une masse de microfibres s'accumule dans l'espace 42 pour être enlevée hors de celui-ci en vue d'une liaison par une résine synthétique. Application particulièrement intéressante dans la purification de l'air comprimée, l'aération, la filtration sous vide, la filtration de liquides, la stérilisation de l'air, etc.
