Abstract

L'invention concerne un procédé de fabrication d'un filtre à air composé d'éléments constitutifs, tel qu'un bouchon supérieur et un bouchon inférieur de filtre à air sous forme d'anneau ou de quadrilatère, des plaques interne et externe perforées, etc., utilisant comme matériaux principaux de la fibre et de la pulpe de coton écologiques. Selon l'invention, les bouchons supérieur et inférieur et les éléments perforés interne et externe sont formés à partir de carton à base de fibre et de pulpe de coton. Le carton utilisé pour les bouchons est découpé selon une forme spécifique en fonction des dimensions requises, trempé dans de l'eau durant 30 à 120 secondes, puis pressé sur un moule correspondant. Le carton utilisé pour les éléments perforés est placé sur une presse comprenant un moule de perforation, perforé à l'aide de ladite presse, puis découpé pour obtenir des dimensions correspondant à des règlements relatifs aux dimensions requises des éléments perforés interne et externe. Le carton découpé pour les éléments perforés est ensuite collé. Un papier filtre et introduit entre l'élément perforé interne et l'élément perforé externe. Les deux extrémités des éléments perforés interne et externe sont couplées aux bouchons supérieur et inférieur avec de la colle. Ces bouchons collés et les éléments perforés sont séchés dans un four sécheur.
