Title (EN) APPARATUS AND METHOD FOR FORMING FILTER RODS
(FR) APPAREIL ET PROCÉDÉ PERMETTANT DE FORMER DES TIGES DE FILTRE
Abstract:
(EN) The invention relates to an apparatus for forming filter rods for aerosol-generating articles. The apparatus comprises a first and a second source, the first source being provided to supply filter material in the form of a first tow, and the second source being provided to supply filter material in the form of a second tow. The apparatus further comprises a single driven delivery roller for advancing the first tow and the second tow and an extrusion tool for processing the first tow and the second tow. The delivery roller is arranged such that the first and second tows are advanced from the first and second source towards the extrusion tool by the delivery roller only. The extrusion tool is configured to process several sources of filter material simultaneously to create one filter rod. The invention also relates to a method for forming filter rods for aerosol-generating articles.
(FR) L'invention concerne un appareil pour former des tiges de filtre pour des articles générant un aérosol. L'appareil comprend une première et une seconde source, la première source étant conçue pour fournir un matériau de filtre sous la forme d'un premier câble, et la seconde source étant conçue pour fournir un matériau de filtre sous la forme d'un second câble. L'appareil comprend en outre un rouleau de distribution entraîné unique pour faire avancer le premier câble et le second câble et un outil d'extrusion pour traiter le premier câble et le second câble. Le rouleau de distribution est agencé de telle sorte que les premier et second câbles sont avancés depuis la première et la seconde source vers l'outil d'extrusion par le rouleau de distribution uniquement. L'outil d'extrusion est conçu pour traiter simultanément plusieurs sources de matériau de filtre afin de créer une tige de filtre. L'invention concerne également un procédé permettant de former des tiges de filtre pour des articles générant un aérosol.
