Title: MEMBRANE PRESS WITH SELF-SUPPORTING BASE AND CLOSURE
Abstract:
A membrane press comprising a closure (12) and a base (14), said base (14) being configured, provide an interior which is able to support a substrate (64) to which a membrane (66) is to be applied, the closure (12) being movable between a closed position over the base (14) at which it defines a closed sealed space between the closure and the base and an open position clear of the base (14) to provide access to the interior of the base (14), whereby when in the closed position the membrane (66) is supported between the closure (12) and the base (14) to define separate spaces above and below the membrane (66), said press further comprising a means (44, 48, 52) to heat the membrane and to create a pressure differential to each side of the membrane (66), said base (14) and closure (12) having sufficient structural strength to be self-supporting against the pressure differential created between the space and the exterior when in use, and locking means (22, 26, 32) provided at spaced intervals around the junction between the closure and base to lockingly retain the closure (12) in the closed position.
