<p>The table comprises a water tank (16) with sloping bottom panels (24) running into a trough (30) which slopes down to a slag collection bin (34) at one end. The trough is resiliently attached to the tank by connectors (92) and sealing strips (100). A submerged grid is formed from intersecting steel bars (44, 46) notched at their intersections to receive upright support elements (64) in the form of lengths of thin walled copper tubing standing on the grid with their upper ends normally a little above the water level. Damaged support elements (64) are individually reversible or replaceable and the support elements allow slag to drop through to the trough (30) which is oscillated by a vibrating mechanism to convey the slag to the bin (34). The array of elements (64) supports even small pieces cut from the workpiece on the table.</p> |
