Abstract

L'invention concerne un dispositif filtrant conique inséré dans une conduite à flux circulant d'amont en aval. Le dispositif filtrant comprend un élément filtrant (62) comportant des cannelures et un logement (54). Le filtre forme un joint d'étanchéité (59) entre le bord externe du filtre sur le côté aval et le logement. La face amont du filtre a une forme conique dans une première forme d'exécution et tronconique dans une seconde forme d'exécution, la forme du logement correspondant approximativement à la forme du filtre. Les éléments filtrants (62) sont formés en enroulant des couches de milieu filtrant pour obtenir une section transversale circulaire. Pour former les éléments, ceux-ci sont déplacés axialement à mesure que se fait l'enroulement ou ils sont placés sur une pièce de formage pendant que le produit d'étanchéité est encore mou.
