Apparatus for controlled removal of surplus material from one or more tows of tobacco particles, filter material for tobacco smoke or the like employs at least one belt conveyor for each stream. The outer side of such belt conveyor is provided with recesses which receive particulate material at the stream forming station or stations. Each stream is equalized by a discrete trimming device which employs a pair of cooperating rotary knives having circular cutting edges and serving to remove the surplus prior to compacting and wrapping of the thus obtained rod-like filler or fillers into web(s) of cigarette paper of the like. The material which has entered the recesses of the belt conveyor(s) contributes to greater density of the corresponding portions of the fillers or fillers, and such densified portions are severed by a cutoff to be located at the ends of plain cigarettes or at the tobacco-containing ends of filter cigarettes.

Apparatus for manipulating tows of filamentary material

The distributor of a cigarette rod maker has a chamber bounded at least in part by a concave guide for a flow of fragments of smokable material in a stream of transporting fluid, such as air. The stream contains a surplus which is withdrawn from a centrally located zone of the chamber by a stationary apparatus having at its underside an inlet for the entry of surplus fluid and containing a nozzle which conveys the surplus fluid to a suction pipe serving to convey the surplus from the chamber.
