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 perforated bottom wall of a suction chamber in the tobacco stream gathering and transporting apparatus of a cigarette rod making machine is designed to guide and support a file of discrete apertured inserts which have undersides serving as abutments for the lower reach of an endless foraminous tobacco stream gathering and advancing belt. Portions of the inserts can be inserted into or removed from one or more grooves provided in the bottom wall and extending longitudinally of a channel which is open from below and has a top wall constituted by the lower reach of the belt as well as by the file of inserts. At least a portion of each insert can be made of a strongly wear-resistant material. An advantage of the inserts is that they render it possible to select the rates of air flow through different portions of the lower stretch of the belt, that they can be made to stand pronounced wear in a high-speed rod making machine, and that replacement of one or a few relatively small inserts often suffices to restore the integrity of a damaged transporting apparatus.

Apparatus for transporting a stream of particulate material

Fragments of plastic fibers, such as cellulose acetate fibers, forming part of mouthpieces of filter cigarettes or like rod-shaped smokers' products tend to become separated from the respective filter mouthpieces at the end faces which develop in response to the making of cuts across filter rod sections of double unit length between pairs of plain cigarettes to obtain filter cigarettes of unit length. The fragments of fibers which tend to become separated and to contaminate the area around the filter cigarette making machine are either bonded (e.g., by heat and/or by a solvent) to the respective mouthpieces, or are removed by suction and/or by resorting to electrostatic precipitation. It is also contemplated to cause smoke-permeable layers of filter material to overlie the end faces of the mouthpieces.
