ABSTRACT:
Method and apparatus for feeding sand molds from multiple sand mold forming stations to a common metal pouring station. The method and apparatus of this invention utilize walking-beam-type conveyors having spaced apart fixed outboard rails and a central reciprocating rail. Walking-beam conveyors are disposed in perpendicular directions with a junction therebetween that allows for a perpendicular change in direction. The method and apparatus of this invention allow multiple parallel walking-beam conveyors to feed sand molds to a single junction for transfer to a metal pouring station.
