Abstract
An arm and cradle apparatus is disclosed for receiving empty trays from an upper conveyor having empty lettuce holding and transporting trays, lowering the received empty tray to an angular disposition in which it can most conveniently be packed, and finally off loading the packed full tray to a lower conveyor having full lettuce holding trays thereon for plunging to cartons. The arm and cradle apparatus is mechanically passive in that all movements of the trays to and from the arm and cradle apparatus are either worker assisted or occur under the natural gravity biased movement of the arm and cradle apparatus.
