摘要： A distributor for tobacco shreds in a cigarette rod making machine employs a system of conveyors which transport a continuous wide layer of tobacco shreds from a magazine toward a channel wherein the shreds form a narrow tobacco stream. A pivotable baffle extends across the path of the layer and a rotary brush or a rapidly moving endless apron propels the shreds of successive increments of the layer at a constant speed against the baffle whereby a potentiometer whose sliding contact shares the movement of the baffle produces signals whose intensity varies as a function of changes in the quantity of shreds per unit length of the layer. The thus obtained signals are used to change the rate of withdrawal of tobacco shreds from the magazine or to intercept a larger or smaller percentage of shreds which are being propelled toward the baffle. The main prime mover of the cigarette rod making machine can be operated at several speeds, and a compensating circuit is provided to prevent the potentiometer from changing the rate of tobacoo feed into the channel in response to changes in operating speed of the prime mover.
