ABSTRACT:
An exhaust fan draws air and entrained tobacco through delivery pipes from a tobacco feeder to the respective dischargers of a group of cigarette making machines, where the tobacco is screened out and the air passes on through exhaust pipes. When a discharger is to release tobacco to its making machine the feeder stops delivery of tobacco to that discharger and, after a delay to clear the delivery pipe, a valve bypasses the air around the discharger so that a constant air flow is maintained. The feeder supplies tobacco in a separate and independently controlled stream to each discharger, and has oscillating vanes to separate and keep the tobacco moving.
