Abstract

La présente invention concerne un procédé et un dispositif de fabrication de paquets (de cigarettes) étanches qui comportent un emballage intérieur (12) doté d'une enveloppe pelliculaire (13) qui entoure le contenu du paquet (un groupe de cigarettes (11)). Le groupe de cigarettes (11) est partiellement entouré d'un collet intérieur (14) doté d'une paroi avant (22). L'enveloppe pelliculaire est séparée d'un tube pelliculaire (18) d'une bande pelliculaire (17) amenée en continu. Le contenu du paquet - un bloc de cigarettes (16) - est amené par un convoyeur de blocs (27) qui immobilise les blocs de cigarettes (16) par complémentarité de formes. Dans la zone de la bande pelliculaire (17) ou du tube pelliculaire (18), une liaison est établie avec le bloc de cigarettes (16) et le collet intérieur (14), et ce par liaison thermique, collage ou analogue, de sorte que le bloc de cigarettes, est fixé à la bande de film (17) dans une position relative précise même après avoir quitté le convoyeur de bloc (27).
