ABSTRACT:
Articles that arrive in a row midway between first and second intercoupled counter-rotary star wheels at an inlet side thereof are regularly distributed among three tracks disposed at an outlet side of the star wheels. The number of teeth on each star wheel is divisible by three and the teeth of one point towards the gaps of the other and are spaced from the roots thereof to allow the arriving articles to be received in the gaps presented alternately by the wheels at the inlet side as they rotate in unison. Alternate teeth of each wheel are provided with retractable pushers for the articles, the other teeth being plain, and alternate pushers of each wheel are equipped with guide tongues. The arrangement is such that, as viewed at the position of the leading arriving article, a plain tooth of the first wheel is followed by a tooth of the second wheel that has a pusher with guide tongue, followed by a tooth of the first wheel that has a pusher without tongue, followed by a plain tooth of the second wheel, and so on, the respective pushers being retracted at the inlet side of the wheels and projected at the outlet side.
