Abstract

Procédé de réalisation d'un filtre formé d'éléments filtrants délimitant entre eux une chambre remplie de matière fluante de filtrage. Le procédé consiste essentiellement à coller les éléments filtrants sur une bande d'enveloppement qui les entoure sur une grande partie, mais qui laisse subsister une fente par laquelle il est possible de déverser la matière fluante dans les chambres qui les séparent, cette fente étant ensuite obturée par un autre ruban. Application essentiellement à la fabrication de filtres à cigarettes dont la bande d'enveloppement est formée d'une matière transparente.
