Abstract
A control apparatus for a cigarette production machine according to the present invention comprises a density sensor for detecting the filling density of shredded tobacco in a continuously formed tobacco rod, an integrator for integrating the output of the density sensor for a predetermined period of time, an arithmetic device for calculating the unit filling (filling amount of the shredded tobacco corresponding to a predetermined length of the tobacco rod) on the basis of an integral value from the integrator, multiplication-type D/A converter for supplying the integrator with an integral gain proportional to the rod speed of the cigarette production machine, and a trimming device for controlling the feed of the shredded tobacco onto a cigarette paper in accordance with the unit filling calculated by means of the arithmetic device.
