ABSTRACT:
A system for automatically forming flaskless sand molds, and preparing them for metal pouring. Cope and drag flasks are alternately filled with chemically bonded sand on an indexing turntable, and the sand is allowed to cure or set up while still on the turntable. The copes and drags are then automatically removed from their respective flasks and placed on a conveyor belt by a rollover draw machine. The above is accomplished automatically, with little or no supervision required.
