Abstract:
A method for the production of a cigarette rod containing particles of an additive material, in a cigarette making machine, including stages of feeding particles of tobacco to a vacuum conveyor, moving at a given speed in order to form a continuous tobacco rod, incorporating the particles of the additive material in the tobacco rod as it is formed, feeding the tobacco rod to a continuous cigarette rod forming station, the particles of the additive material being positioned substantially along an axis of the cigarette rod, and cutting the cigarette rod into lengths using a rotary cutting device designed to cyclically cut the cigarette rod at transversal cutting lines, wherein the stage of incorporating the particles of the additive material in the tobacco rod comprises the stages of feeding the particles of the additive material to a distributor having a rotary conveyor with seats distributed on a cylindrical side wall thereof and ejecting the particles of the additive material towards the tobacco rod from the rotary conveyor through at least one ejection channel and wherein the seats in the cylindrical side wall consist of cells which are flared towards the outside and wherein the rotary conveyor rotates within a fixed ring-shaped structure.
