  • Automatically adapting vacuum holder
    Patent number: 6371430
    Abstract: This invention relates to a vacuum holder for securing workpieces, such as flexible media or printed circuit boards, through a suction force. Pressure responsive, one way flow valves are incorporated between chambers under suction openings to control the application of suction. This results in a restraining force that is uniform in time and space, resulting in a vacuum holder that has reduced pumping requirements.
