Abstract

L'invention concerne un séparateur tangentiel (10) servant à séparer le tabac (50) contenu dans un courant air-tabac, comprenant un tambour d'aspiration (20) pourvu d'ouvertures de passage (20). Le séparateur (10) selon l'invention est caractérisé en ce que les ouvertures de passage du tambour d'aspiration (20) sont disposées de manière irrégulière dans la direction circonférentielle et dans la direction axiale, au moins partiellement sur l'enveloppe latérale du tambour d'aspiration. Dans un autre mode de réalisation, l'enveloppe latérale du tambour d'aspiration est ouverte en direction radiale. Dans un autre mode de réalisation, la section transversale du tambour d'aspiration du séparateur tangentiel (10) diminue ou augmente dans la direction de l'axe longitudinal. Cette invention se rapporte en outre à une machine destinée à l'industrie du tabac, en particulier une machine de production de cigarettes, ainsi qu'à une installation destinée à l'industrie du tabac.
