  • the apparatus and method described cause the cigarettes to be wrapped relatively slowly even while being moved through the tipping machine at a very high speed.

Abstract

Procédé et appareil pour envelopper un matériau de bout autour d'un assemblage comportant un boudin de tabac et un filtre, les deux étant des sections transversales circulaires ou non circulaires. L'assemblage de cigarettes est roulé le long de la surface d'un tambour de roulage (71) par un élément de pression voisin (94) qui est déplacé dans la même direction que la surface périphérique du tambour, mais à une vitesse différente. La différence de vitesse provoque le roulement de la cigarette assemblée le long de la surface du tambour. L'élément de pression, qui est de préférence une courroie (134), est conçu pour exercer une pression pratiquement constante sur l'assemblage de cigarettes malgré la forme irrégulière de ce dernier. Le procédé et l'appareil décrits, comparés à un procédé et un appareil similaires conventionnels, permettent le transport de filtres ovales de telle façon que chaque filtre ovale possède la même orientation prédéterminée.
