ABSTRACT:
A method and apparatus for counting indeterminately spaced articles traveling in a continuous stream. Successive individual lead articles of the stream are diverted from their direction of movement in an oblique direction. A sensor located beneath the stream at the point of oblique movement detects the sequential presence and absence of articles which information is accumulated to obtain a count. For counting rod-shaped articles, such as cigarettes, the method may be embodied in a drum having a helical groove to move the rods, the drum being located above a reflective scanning sensor head.
