Abstract: A storage station for receiving workpieces from a loading conveyor belt and for sending workpieces to an unloading conveyor belt. The station has a plurality of spaced platforms mounted on a common rotatable shaft, and apparatus for adjusting the vertical position relative to the rotary platforms of the ends of the loading and unloading conveyor belts which are proximal to the station. A first guide is provided for each platform for directing workpieces riding on the outer radial region of the respective platform toward the inner radial region of that platform when the first guide is in a first position.
