Title
(EN) METHOD AND MACHINE FOR MAKING A SUB-UNIT OF A SMOKING ARTICLE
(FR) PROCÉDÉ ET MACHINE DE FABRICATION D'UNE SOUS-UNITÉ D'UN ARTICLE À FUMER
Abstract
(EN) A method for making a sub-unit of a smoking article, comprising the steps of: preparing at least one rod-shaped segment (1) and a tubular body (2'a, 2''a, 2'''a, 2''''a), stably connected to each other and aligned along an axis of said sub-unit (100), the tubular body (2'a, 2''a, 2'''a, 2''''a) defining internally a containment chamber (4) and extending between a first end, connected to the segment (1), and a second end having an access opening (5) to the containment chamber (4); inserting a filler material into the containment chamber (4) of the tubular body (2'a, 2''a, 2'''a, 2''''a) through said access opening (5); closing at least partly said access opening (5) to prevent the escape of said filler material from the containment chamber (4); wherein said second end of the tubular body (2'a, 2''a, 2'''a, 2''''a) has a shape defining a succession of closing tabs (10) arranged one after another along a peripheral extension of said second end and alternated with corresponding recesses (20) and wherein said step of closing the access opening (5) comprises a step of folding said tabs (10) transversely to said axis to at least partly obstruct said access opening (5).
(FR) L'invention concerne un procédé de fabrication d'une sous-unité d'un article à fumer, le procédé comprenant les étapes consistant à : préparer au moins un segment en forme de tige (1) et un corps tubulaire (2'a, 2''a, 2'''a, 2''''a) reliés de manière stable l'un à l'autre et alignés le long d'un axe de ladite sous-unité (100), le corps tubulaire (2'a, 2''a, 2'''a, 2''''a) définissant intérieurement une chambre de confinement (4) et s'étendant entre une première extrémité reliée au segment (1), et une seconde extrémité ayant une ouverture d'accès (5) à la chambre de confinement (4) ; insérer un matériau de remplissage dans la chambre de confinement (4) du corps tubulaire (2'a, 2''a, 2'''a, 2''''a) par ladite ouverture d'accès (5) ; fermer au moins partiellement ladite ouverture d'accès (5) pour empêcher la fuite dudit matériau de remplissage de la chambre de confinement (4) ; ladite seconde extrémité du corps tubulaire (2'a, 2''a, 2'''a, 2''''a) ayant une forme définissant une succession de pattes de fermeture (10) disposées les unes après les autres le long d'une extension périphérique de ladite seconde extrémité et alternées avec des évidements correspondants (20) et ladite étape de fermeture de l'ouverture d'accès (5) comprenant une étape de pliage desdites pattes (10) transversalement audit axe pour obstruer au moins partiellement ladite ouverture d'accès (5).
