Abstract
The density of the trimmed tobacco stream in a cigarette rod making machine is monitored and the distance between the trimming plane and the conveyor for the tobacco stream is varied in dependency on deviations of the monitored density from an optimum density. The variations in the distance between the trimming plane and the conveyor are monitored and the signals denoting such variations are used to adjust the rate of tobacco feed into the stream building zone of the machine. The rate of feed is reduced when the distance between the trimming plane and the conveyor is reduced and vice versa. The quantity of removed surplus is monitored and the rate of tobacco fed is or can be regulated in response to signals denoting changes in the quantity of removed surplus. Alternatively, monitoring of the surplus can be used solely to generate signals which denote that the quantity of surplus tobacco is outside of a preselected range.
