Abstract
An adjustable distributor transports particles of tobacco into a stream building zone wherein the tobacco is converted into a stream containing a surplus of particles. The surplus is removed by an equalizing device and the equalized stream is converted into a rod-like filler. An optical level detector monitors the height of the stream ahead of the equalizing device, and a second detector monitors the height of the equalized stream. Signals which are furnished by the detectors are transmitted to the corresponding inputs of a dividing circuit whose output transmits signals which are used to adjust the distributor in such a way that the rate of tobacco transport to the stream building zone is increased when the quantity of removed surplus decreases and vice versa. The equalizing device, together with the second detector, is movable transversely of the tobacco stream in response to signals from a detector which monitors the density of the filler.
