ABSTRACT:
An apparatus for determining a tobacco shred filling quality includes a rotational position detector for detecting the rotational position of a driving drum of a cigarette manufacturing apparatus, a density detector for continuously detecting a tobacco shred filling density of a continuous cigarette rod, and a controller which receives the outputs of both detectors. The controller samples a density signal from the density detector every time it receives a pulse signal from the rotational position detector during a period corresponding to a distance from the beginning of the rear end portion of each double cigarette rod to the end of the front end portion of a succeeding double cigarette rod, and integrates the sampled density signal over a period corresponding to each end portion of each double cigarette rod. When the integration result falls below an allowable lower limit, the controller determines that tobacco shreds are likely to fall from the ends of the double cigarette rod during the manufacturing process, and eliminates this double cigarette rod when it reaches a filter attachment section.
