ABSTRACT:
A vacuum hold-down table (36) is provided for holding sheet material (40) in place. The vacuum hold-down table (36) includes a plurality of foam layers (542, 544, 546, 548, 550, 552) integrally united to form a laminated monolithic core portion (560) for the table (36). A plurality of apertures (580) extend throughout the core portion (560), such that air flows throughout the core portion (560). A vacuum is provided through structure (608, 610) to the core portion (560) to effectuate a vacuum within the core portion (560) to generate a high flow rate of air passing through the apertures (480) and thereby maintain sheet material (40) on the surface (38) of the table (36).
