Abstract
A cigarette rod making machine wherein the distributor forms a continuous stream of tobacco particles including freshly admitted tobacco particles and surplus which is removed from the stream by a trimming device. Fresh tobacco particles are drawn from a duct and are converted into a shower which is classified prior to admission of the surplus. The surplus is admitted across the full width of the shower of fresh tobacco in such quantities that the combined mass of the surplus and fresh tobacco in the trimmed stream is substantially constant. This is achieved by monitoring the quantity of surplus which is removed from the stream and regulating the rate of admission of fresh tobacco in accordance with the characteristics of signals denoting the monitored quantities of the surplus.
