A method of attaching a membrane across an opening of an annular deformable wall including the steps of placing a disc across the opening with the disc extending outwardly beyond the wall, and deforming the outer edge of the disc and the wall simultaneously by applying heat and pressure thereto to fuse the outer edge of the disc onto the wall.
