ABSTRACT:
A sealing assembly for use in a press having one or several openings defined by a number of platens, consisting of a plate to which an inflatable, flexible seal with a protective retainer is attached and is installed in the space in each opening by suspending it to the bottom side of each platen. After closing of the press, positive air pressure is delivered into the sealing element to gradually inflate the sealing element causing a tight sealing of the space between the platens irrespective of the irregularities existing in the contact surface of the sealing element. A vacuum can be applied to remove any contaminants and/or gasses trapped in the space enclosed by the sealing assembly.
