ABSTRACT:
A device for controlling the content of tobacco in a cigarette machine, for feeding the tobacco content along an air-permeable conveyor band, trimming the tobacco content thereon, wrapping them in paper, thereby continuously producing stick-like cigarettes. The device comprises a first radiometric density detector, arranged in front of a trimming position, for detecting the density of the tobacco content; and a second radiometric density detector, for continuously detecting the densities of the stick-like cigarettes, wherein the sum signal representing an integrated value of outputs from the second radiometric density detector and an output from the first radiometric density detector is used to control the trimming and hence the tobacco content in the cigarette manufacturing machine.
