ABSTRACT:
A stream which advances along the underside of the elongated lower reach of an endless air-permeable belt conveyor carries a surplus of fibrous material and is relieved of the surplus by a trimming device which is mounted downstream of one or more nozzles serving to direct compressed air at a variable rate against successive increments of the stream and to thus loosen the stream to a greater or lesser extent, at least in a region immediately adjacent the underside of the lower reach of the conveyor. The upper side of the lower reach of the conveyor is adjacent a suction chamber which attracts the stream to the conveyor. The action of suction upon the stream in the region of the nozzle. or nozzles can be weakened or elminated by the nozzle or nozzles or by a discrete barrier. The density of the trimmed stream is monitored and the results of the monitoring operation are used to regulate the rate of admission of compressed air to the nozzle or nozzles so that the rate of admission respectively increases and decreases when the density is excessive or too low. The nozzle or nozzles can obviate the need for adjustment of the trimming device relative to the lower reach of the conveyor. The trimmed stream is draped into a web of cigarette paper or the like and is subdivided into rod-shaped smokers' products, such as cigarettes, cigars, cigarillos or filter rod sections.
