Abstract: A dense-end monitor and controller is provided for a cigarettemaking machine of the dense-ending type. In a preferred embodiment, a density gauge is positioned adjacent to the moving cigarette rod for providing a first signal varying with the occurrences of dense portions in the tobacco rod. Another signal is supplied for each cutting action of the rod cutter by means synchronized to the rod cutter. Correlation waveform generators generate sawtooth and triangular-shaped waveforms which are phase-synchronized with the dense portion pulses in the density gauge signal. Two output signals, one representing deviation of the dense portions from their proper position at the ends of the cut cigarettes, and the other representing the relative increase in the amount of tobacco in the dense portions, are provided for visual display and machine control purposes. The signals are obtained by correlating the density signal with the triangularshaped waveform and by sampling the sawtooth-shaped waveform at the instant the cutter signal is generated. The output signals are free of any interdependence of information content.
