Abstract
The density of a stream of tobacco particles at the underside of a foraminous belt conveyor is monitored by an array of X-ray detectors to generate signals each denoting the density of a different thin layer in successive increments of the stream. Such signals are processed into signals denoting the density of the entire stream, the filling power of tobacco, and the quantity of the surplus in the stream. The processed signals are used to adjust the trimmer which removes the surplus, to adjust the distributor which feeds the particles to the stream, to regulate the hardness of cigarettes and to adjust the quantity of the surplus.
