A method of detecting and rejecting poorly filled cigarettes, whereby cigarettes, arranged along a gravity channel forming part of an outlet of a feedbox, are fed successively past a detecting device facing one end of the cigarettes; the detecting device, as the cigarettes file past, emits a continuous signal having a succession of minimum values indicating the passage past the detecting device of a succession of gaps, and a succession of maximum values indicating the passage past the detecting device of respective cigarettes; and a receiving central control unit emits a reject signal on receiving a maximum value below a given threshold value.
