Abstract

Pour réaliser l'élément, on part d'une couche fibreuse, on la conforme en corps tubulaire carré ou rectangulaire, puis on replie intérieurement sur eux-mêmes deux côtés opposés 2 à partir du milieu de leurs bords libres, de sorte que ces bords et ceux des deux côtés 4 viennent en contact suivant une arête unique 5 qu'on ferme de façon étanche par soudure. L'élément peut se monter dans un cadre 12. En variante 12 peut renfermer plusieurs éléments carrés ou rectangulaires. 12 peut être en deux pièces. Les bords de l'élément peuvent être relevés pour former jonctions ou brides, etc. Réalisation de filtres à éléments de faible coût.
