Title (EN) APPARATUS AND ASSOCIATED METHOD FOR FORMING A FILTER COMPONENT OF A SMOKING ARTICLE AND SMOKING ARTICLES MADE THEREFROM
(FR) APPAREIL ET PROCÉDÉ ASSOCIÉ POUR FORMER UN COMPOSANT DE FILTRE D’UN ARTICLE À FUMER ET ARTICLES À FUMER QUI EN SONT CONSTITUÉS
Abstract: front page image
(EN)An apparatus and associated method for forming a filter rod member of a smoking article, such as a cigarette, is provided. The apparatus comprises a rod-forming unit configured to form a continuous supply of a filter material into a continuous cylindrical rod member. An insertion unit is configured to insert an adsorbent material carried by a carrier material into the rod member. The method comprises forming a continuous supply of a filter material into a continuous cylindrical rod member, and inserting an adsorbent material carried by a carrier material into the rod member such that the adsorbent material is disposed within the rod member. Also provided are cigarette filters including at least one filter segment (32) having one or more composite fiber structures (60) or degradable fibers imbedded therein, the composite fiber structure including a carrier fiber and an adsorbent fiber, the adsorbent fiber including an adsorbent material.
(FR)L’invention concerne un appareil et un procédé associé pour former un élément tige de filtre d’un article à fumer, tel qu’une cigarette. L’appareil comporte une unité formant tige configurée pour former une alimentation continue d’un matériau de filtre dans un élément tige cylindrique continu. Une unité d’insertion est configurée pour insérer un matériau adsorbant porté par un matériau porteur dans l’élément tige. Le procédé consiste à former l’alimentation continue d’un matériau de filtre dans un élément tige cylindrique continu, et à insérer un matériau adsorbant porté par un matériau porteur dans l’élément tige de telle sorte que le matériau adsorbant est disposé dans l’élément tige. L’invention concerne également des filtres de cigarette qui comprennent au moins un segment de filtre ayant une ou plusieurs structures de fibre composite ou de fibres dégradables incorporées dedans, la structure de fibre composite comprenant une fibre porteuse et une fibre adsorbante, la fibre adsorbante comprenant un matériau adsorbant.
