The wrapped cigarette rod which is formed in a cigarette making machine is monitored by a beta ray detector which generates first signals denoting the density of successive unit lengths of the moving rod. The first signals are compared with a reference signal which denotes the desired density of the rod, and the resulting third signals are squared, N squared signals are totalized and the resulting fourth signals are divided by signals denoting N - 1 first signals to form sixth signals. The square roots of sixth signals constitute regulating or adjusting signals which enable the attendants to feed tobacco or other fibrous material at an optimum rate. The regulating signals are converted into visible signals. The first signals can be used to adjust the position of the device which removes the surplus from a continuous tobacco stream to form a filler which is thereupon wrapped to constitute the cigarette rod.

Method and apparatus for generating signals for adjustment of cigarette

A tray filling apparatus wherein a suction head accumulates rows of cigarettes and a pusher transfers the rows into a tray which is supported by an endless chain conveyor. The suction head and the pusher receive motion from a drive which includes a variable-speed DC-motor, a step-down gearing which is driven by the output shaft of the motor, and a mechanical transmission having a first component which moves the suction head between a lower position in which the latter accumulates a row of cigarettes and one of two raised positions, and a second component which moves the pusher forwardly not later than when the suction head reaches a raised position. The forward movement of the pusher is slower than its return movement to retracted position and the characteristic RPM curve of the motor is determined by a control circuit which includes three signal generators one of which starts the motor, another of which decelerates the motor after the suction head returns to lower position and the pusher reassumes its retracted position, and the third of which arrests the motor while the suction head and the pusher respectively dwell in their lower and retracted positions. A second electric motor drives the conveyor for an empty or partly filled tray through the medium of a second transmission in stepwise fashion upon completion of each forward stroke of the pusher.
