Abstract
Apparatus for monitoring the flow of a stack of cigarettes in a conveyor system using a television camera tube or light-sensitive detectors positioned adjacent the ends of the cigarettes, preferably in an array or row covering the whole height of the stack, to monitor the formation of the stack and to produce pulse signals representing the articles present. The sensors are scanned by control circuitry which produces control signals in response to the number or speed of articles detected.
