Abstract
A singulator conveyor receives randomly oriented articles and positions those articles in single file. The conveyor includes skewed rollers for driving articles longitudinally and laterally against a side wall. The width of the singulator conveyor becomes gradually stepped-down, and a return conveyor system is provided which includes secondary return conveyors or chutes disposed at respective ones of the steps for receiving excessive articles from the singulator conveyor and delivering them to a main return conveyor which returns the articles to an upstream end of the singulator conveyor.
