Abstract

A first stream of tobacco particles is subdivided into several narrower streams at a diverting station where the lowermost portions of several upwardly sloping panels are inclined with reference to each other and with reference to a foremost panel which guides the first stream. First nozzles which discharge compressed air are used to compel the particles of the first stream to advance along the concave upper side of the foremost panel, and additional nozzles are used to discharge compressed air which compels the second streams to advance along the concave upper sides of the respective panels. The distribution of particles across the first stream and/or at the diverting station can be regulated by one or more partitions at the diverting station, by nozzles which blow particles across the first stream, by a pivotable flap in the distributor which supplies particles to the building zone for the first stream, or by a pivotable flap in a vibratory conveyor which returns to the distributor surplus particles removed from the second streams during their conversion into rod-like fillers of discrete tobacco rods.
