ABSTRACT:
A cigarette making machine includes a channel (10; 100; 204) through which tobacco is pneumatically conveyed to form a cigarette filler stream (15; 209) on a conveyor (12; 130; 200) at the outlet of the channel, a first louvre (20; 110; 214) through which some of the air entering the channel through its inlet end is drawn from the channel while tobacco continues towards the conveyor, and a second louvre (22; 120; 216), closer than the first louvre to the outlet end of the channel, through which an additional amount of the air entering the channel is drawn while the tobacco continues towards the conveyor. The channel (202) may be arranged to extend around a cylinder with an inclined axis (208) so that upward movement of the tobacco is converted into approximately horizontal movement with a substantial component in the direction of movement of the conveyor (200) on which the tobacco collects to form a cigarette filler stream (209).
