Abstract

A shower of tobacco particles is fed into the upper end of a downwardly sloping and downwardly tapering funnel-shaped part of a conveyor wherein the particles gather into a flow of interlaced particles. Successive increments of the flow are acted upon by one or more jets of air issuing from at least one nozzle which loosens successive foremost increments of the flow prior to admission into a tobacco filler rod forming unit in a cigarette rod making machine.
