Abstract:
A method of airtight joining first and second flexible membranes comprising the steps of:a) producing a curvature in a first membrane by increasing the pressure on the first membrane; b) contacting the convex surface of the first membrane with a second membrane; c) pressing the convex surface of the first membrane into the second membrane to produce a concave surface in the second membrane; d) joining the first and second membranes, at least in part by increasing the curvature of the first membrane, until the edges of the first and second membranes come into contact; and e) pressing together the first and second membranes to seal the edge area of the first membrane to the edge area of the second membrane and form an airtight seal between the two membranes.
