ABSTRACT:
A cigarette rod making machine wherein a shower of tobacco particles is attracted to the underside of the straight horizontal lower reach of an endless air-permeable conveyor which advances the fully grown stream through a surplus removing station before the stream enters the wrapping mechanism wherein it is draped into a web of cigarette paper. Spaced-apart portions of the stream are pneumatically densified at the surplus removing station by attracting the fibrous material against the lower reach of the conveyor or in another direction so as to reduce the quantity of the removed surplus. This can be achieved by utilizing one or more rotary valving elements which connect the corresponding portion of the path for the stream with one or more suction chambers so as to effect a more pronounced densification of the corresponding portions of the stream.
