Abstract

A downdraft exhaust cutting and shuttle table mechanism (10) includes a cutting area (12) and a loading area (70), which includes first and second elongated, horizontally disposed cutting tables (80a and 80b) which are shuttled into and out of a cutting area (12) which includes a material cutting assembly (24) positioned therein, the shuttle table mechanism (10) including horizontal and vertical table movement devices which are operative to move the first and second cutting tables (80a and 80b) forwards and backwards between the cutting area (12) and a loading area (70) generally adjacent thereto and a vertical table movement device operative to move the first and second cutting tables (80a and 80b) upwards and downwards, the vertical and horizontal table movement devices cooperating to move each of the first and second cutting tables (80a and 80b) from a loading position generally horizontally forwards into the cutting area for cutting of material mounted thereon then generally horizontally backwards into the loading area (70) to a position generally underneath the other of the cutting tables (80a and 80b) which has been lifted into the elevated loading position, thereby cycling the first and second cutting tables (80a and 80b) to alternate use of each.
