<p>In a method and apparatus for counting indeterminately spaced articles 6a, 6b etc. travelling in a continuous stream, successive individual lead articles 6a of the stream are diverted from their direction of movement in an oblique direction. A sensor 5 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, a drum 2 having a helical groove 4 may be used to move the rods, the drum being located above a reflective scanning sensor head.</p> |
