A distributor for use in a cigarette rod making machine has a magazine for shredded tobacco, a carded drum which rotates about a horizontal axis and draws from the magazine a continuous layer of tobacco shreds toward its apex, a homogenizing device which equalizes the layer between the region where the shreds are being withdrawn from the magazine and the apex, a rapidly rotating picker roller which is adjacent to the apex of the drum and expels the shreds of the equalized layer tangentially from the carding of the drum whereby the flight spans of heavier tobacco particles exceed the flight spans of other tobacco particles. The other tobacco particles descend onto and form a sliver on a wide belt, and the heavier particles are intercepted by a receptacle. A second picker roller expels remnants of tobacco particles from the carding and transfers such particles onto the belt. The homogenizing device may include a strip which extends in parallelism with the axis of the drum and is reciprocated by an electric motor. The underside of the strip is grooved and contacts the exposed side of the tobacco layer, and the upper side of the strip is adjacent to the path of paddles on a rotating wh…
