A cigarette manufacturing machine of the continuous rod type in which a stream of tobacco particles flows upwardly through a vertical duct and feeds a conveyor system to form a tobacco layer or filler and feed it to a continuous cigarette rod forming apparatus. The conveyor system includes an air-permeable mobile belt which spans the duct outlet and extends to the cigarette rod forming apparatus. During its formation and transfer, the tobacco layer is retained on the belt by suction applied to the belt face opposite the face holding the filler. The suction is divided with first suction apparatus operating on the belt portion disposed over the duct outlet, and with second suction apparatus, independent of the first, operating on the belt portion between the duct edge and the cigarette rod forming apparatus. |
