Abstract
A method for airtight joining of two membranes. An airtight and complete bonding of the two membranes is achieved by first producing a curvature in one of the membranes, then placing the convexly curved side of a membrane onto the membrane to be joined to it in an airtight manner, next joining the two membranes until the edge areas of the membranes are in contact, and finally applying a pressing force that seals the edge areas of the membranes in an airtight manner.
