Abstract
An apparatus for controlling the flow of articles from an upstream delivery station to a downstream receiving station and for temporarily storing the articles on a pair of parallel conveyors with a substantial run of the conveyors being in a vertically extending spiral made up of an incoming conveyor and an outgoing conveyor. A movable transport member is used for transferring the articles from the incoming conveyor and the outgoing conveyor at a rate dependent upon the relative speed of the two conveyors.
