Title (EN) APPARATUS AND ASSOCIATED METHOD FOR FORMING A FILTER COMPONENT OF A SMOKING ARTICLE
(FR) APPAREIL ET PROCÉDÉ ASSOCIÉ POUR FORMER UN COMPOSANT DE FILTRE D'UN ARTICLE À FUMER
Abstract:
(EN) Apparatuses, systems, and methods employing ultrasonic bonding 241 to form filter elements for smoking articles are provided. Ultrasonic bonding can be employed to bond the fibers of filter material defining bloomed tow. Use of a plasticizer may not be necessary. Further, filter materials such as polylactic acid, which may not be bonded via a plasticizer, may be employed. However, triacetin or other additional components may be employed to provide the filter element with a desirable sensory attribute in some embodiments. Ultrasonic bonding may be conducted by an ultrasonic bonder that includes an anvil defining a pattern thereon that is selected to define a desired degree of bonding, and thereby a resulting desired firmness and/or pressure drop associated with the filter element.
(FR) L'invention concerne des appareils, systèmes et procédés utilisant le liage par ultrasons pour former des éléments filtres pour articles à fumer. Le liage par ultrasons peut être utilisé pour lier les fibres du matériau de filtre définissant la mèche traitée. L'utilisation d'un plastifiant peut ne pas être nécessaire. En outre, des matériaux de filtre tels que l'acide polylactique, qui peuvent ne pas être liés par le biais d'un plastifiant, peuvent être utilisés. Cependant, la triacétine ou d'autres composants supplémentaires peuvent être utilisés pour conférer à l'élément filtre un attribut sensoriel souhaitable dans certains modes de réalisation. Le liage par ultrasons peut être réalisé grâce à un agent de liaison par ultrasons qui comprend une enclume définissant un motif sur celui-ci qui est choisi pour définir un degré souhaité de liage et ainsi une solidité et/ou chute de pression souhaitées résultantes associées à l'élément filtre.
