  • System for vapor injection pressing
    Patent number: 5096409
    Abstract: Particle board, hard board, wafer board, plywood and the like are formed by vapor injection pressing using thin plates through which steam is injected into the product under consolidation, the thin plates lying adjacent the press platens. For closed steam pressing, the plate is provided with a peripheral seal which is inflatable to seal the cavity of the press using either the same stream which is injected into the product, or a second source of steam or other gas at a higher pressure.
