ABSTRACT:
A table and a gas-driven cutting apparatus are provided. The table supports a workpiece in a manner suitable for cutting of the workpiece by the gas-driven cutting apparatus. The table includes an open table top having a plurality of openings for receiving the forced hot gases and a plurality of distributed horizontally arranged contact points for supporting the workpiece. The openings are distributed throughout the table top independently of the cutting paths of the gas-driven cutting apparatus. The table further includes a ventilated stationary negative pressure, situated below the table top and coupled to each of the openings. The table may include a plurality of vertically arranged slats having longitudinal axes extending across the open table top. A plurality of horizontally extending members (e.g., having an inverted V-shape) may be placed between each pair of slats that extend across the open table top. The horizontally extending members together form downwardly angled upper surfaces, each having a lower terminating end that forms a restricted opening in direct contact with the inside of the negative pressure chamber.
