| 摘要 |
The present invention relates to an apparatus and method for manufacturing products such as laminates or thermal moldings. The apparatus includes a first member, a flexible sheet, and a cord and channel arrangement to mount the flexible sheet to the first member to form an enclosed chamber. Valve structure is provided in airflow communication with the enclosed chamber. The apparatus may be used as a vacuum frame apparatus wherein the enclosed chamber receives product for exposure to a vacuum environment. Heat may be applied to facilitate manufacturing. External force may be provided to the product through external mechanical structure or an external pressure greater than atmospheric pressure external of the enclosed chamber. In another embodiment, the apparatus may be used as a membrane press wherein the product is outside the enclosed chamber and the enclosed chamber is pressurized to a pressure greater than atmospheric pressure such that the flexible sheet, sometimes heated, is pressed against the product. Sometimes a vacuum assist may be provided to draw the flexible sheet toward the product.
