Abstract
One or more streams of tobacco in a rod making machine are tested by several density monitoring units one of which employs a source of nuclear radiation and at least one other of which employs a source of optical radiation. The resulting density signals are evaluated and converted into signals which are devoid of the influence of changes of color and/or blend of fibrous material in the stream or streams and are used for segregation of defective rod-shaped articles and/or for controlled removal of surplus from the stream or streams.
