Abstract
A method for constructing a balloon assembly includes inserting balloon envelope material which will become an apex of a balloon envelope into a platen opening of a platen; flaring the balloon envelope material outward over the top surface of the platen; positioning a termination plate over the platen opening and within the apex opening; and folding at least some of the balloon envelope that overlies the platen onto the termination plate. The balloon envelope material further includes an apex opening.
