ABSTRACT:
A method of checking cigarettes, whereby cigarettes are fed in steps along a gravity channel in the outlet of a hopper, and are successively arrested substantially at a checking station where a checking device determines the density of the open ends of the cigarettes and emits at least one control signal indicating the density; and the control signal is optimized by determining the position of the cigarette in the checking station with respect to the checking device.
