<p>The shaker apparatus comprises a movable table mounted in a cylinder fitted with a piston, and an anvil that moves in the cylinder, such that the anvil and table pulsate in relative motion to one another. The shaker and the mould-casing are pressed against a sand-container so that the free upper edge of the casing contacts the feed-edge of the container. Flexible and elastic elements are mounted between these two edges, and between the table and the cylinder positioning surfaces.</p> |
