Abstract
A tobacco metering, conveying and separating system (10) is provided for feeding cut tobacco from a source thereof (12) to a cigarette-making machine at a substantially lower rate, with consequential decrease in tobacco degradation than in conventional systems. A continuous air flow is used in the conveyor pipe (32) and a rotary air lock (50) is used to discharge tobacco from the tobacco-air separator (34).
