Abstract

L’invention concerne une membrane de filtre capable d’empêcher que les crêtes de plis adjacents les uns des autres ne s’assemblent les unes aux autres à un coût avantageux sans utiliser de séparateur, permettant une rigidité et une résistance accrues dans le sens des lignes de plis, et capable d’augmenter l’effet de décolmatage à contre-courant. La membrane de filtre (1) formée dans un pli comprend des parties pliées et empilées (10a) et (10b) s’étendant dans le sens orthogonal aux lignes de pliage (2a) et (2b) des plis. Les parties pliées et empilées (10a) et (10b) sont constituées en repliant la membrane de filtre (1) à travers les premières lignes de plis (11) et (11’) et les secondes lignes de plis (12) et (12’). La membrane de filtre (1) en trois parties est formée de parties internes (1a) et (1a’), de parties externes (1b) et (1b’), et de parties intermédiaires (1c) et (1c’) entre les premières et les secondes lignes de plis (11) et (11’) et (12) et (12’). Dans la membrane de filtre cylindrique (1), les parties pliées et empilées (10a) et (10b) sont formées près des parties intermédiaires entre la partie centrale verticale et ses extrémités supérieure et inférieure, et les poches externes (13) et (13’) correspondantes sont ouvertes aux extrémités supérieure et inférieure.
