Abstract
The density of successive increments of two neighboring rod-like flows of tobacco particles in a cigarette rod making machine is determined by an apparatus which employs a source serving to emit a divergent beam of X-rays across the paths for the two flows so that the radiation which has penetrated through and issues from the two flows is indicative of the density of the respective flows. Such intensity is ascertained by discrete X-ray detectors which transmit corresponding signals to an evaluating circuit. The latter compares such signals with a reference signal denoting the intensity of a portion of radiation which has bypassed the flows, and the evaluating circuit can further compensate for the difference, if any, between the distances of the two paths from the radiation source.
