Abstract

L'invention concerne une cigarette à filtre qui permet de déterminer la quantité de rotation relative entre des éléments respectifs sans nécessiter de confirmation visuelle, lors de la rotation relative d'éléments filtrants aptes à tourner les uns par rapport aux autres autour de l'axe longitudinal d'un filtre. La cigarette à filtre selon la présente invention est pourvue : d'une partie de tige de tabac ; et d'un filtre qui est relié à une extrémité de la partie de tige de tabac par l'intermédiaire de papier manchette, et dont la circonférence externe est enroulée par le papier manchette, le filtre comprenant un premier segment et un second segment qui est rotatif autour de l'axe longitudinal du filtre par rapport au premier segment, le papier manchette comprenant une première partie de bande fixée au premier segment et une seconde partie de bande qui est fixée au second segment, et qui est disposée de sorte que sa face d'extrémité annulaire vienne en butée contre une face d'extrémité annulaire de la première partie de bande, et les faces d'extrémité annulaire des première et seconde parties de bande étant pourvues de griffes de mise en prise qui doivent s'engrener les unes aux autres.
