  • Vacuum transfer seal
    Patent number: 8158051
    Abstract: An intermediate sealing element and method for unsealing a vacuum membrane from one tool surface and transferring it to another tool surface without damaging the vacuum membrane. The intermediate sealing element forms a continuous path around the periphery of a vacuum membrane and is sealed directly to one or more vacuum membranes and a tool surface using any means known in the art to create an airtight seal between two surfaces. The intermediate sealing element is able to withstand high temperatures and high pressure without altering its structural characteristics. Because of its durability, the intermediate sealing element can be removed from the tool surface without tearing or elongating, subsequently allowing the vacuum membranes to be detached from the tool surface without tearing or elongating.
