ABSTRACT:
In a machine for simultaneously producing two continuous cigarette rods from respective layers of tobacco, shredded tobacco is fed by an air current along an upfeed duct, closed off at the top by a first and a second suction conveyor, in such a manner as to form two substreams mainly consisting respectively of light and heavy tobacco particles and directed respectively towards the first and second conveyor. Each of the two substreams impinges, along the upfeed duct, on respective deflecting and mixing elements, which deflect part of each substream towards the other substream so as to feed two substantially identical final secondary streams onto the suction conveyors.
