Abstract
For monitoring the end dropout of cigarettes in the course of the cigarette production beneath a point at which the cigarettes rotate about their longitudinal axis a mass transducer for the dropping tobacco particles is disposed; an evaluating device determines from the mass of the tobacco particles on the one hand and the number of cigarettes passing through on the other the average end dropout. The mass transducer includes a vertically movably resiliently mounted pushrod which is held in its desired position by an electromagnetic return system. The magnitude of the current supplied to an electromagnetic return system represents a measure of the mass of the collected tobacco particles.
