Abstract
The combined mass flow of solid and liquid fractions of a fibrous material which is converted into a tobacco rod or filter rod in a rod making machine of the tobacco processing industry is ascertained by monitoring the liquid fraction in the distributor of the machine and by monitoring the solid fraction downstream of the monitoring station for the liquid fraction. Electric signals which are obtained as a result of such monitoring are processed in a computer which transmits a signal denoting the combined mass flow of solid and liquid fractions. Such signal is used to maintain the combined mass flow at or close to a preselected value, particularly by adjusting a trimming device which removes the surplus of fibrous material ahead of the station where the fibrous material is draped into a web of cigarette paper, imitation cork or other wrapping material.
