ABSTRACT:
A support table for foundry sand molding machines is elevated from a lowermost position to a sand supply position wherein sand is fed into a flask supported on the table. The table is then moved downwardly to a predetermined position slightly above the lowermost position while being vibrated to compact the sand. The table is then elevated to an upper position for squeezing the sand against a squeeze board carried by a head on the machine.
