ABSTRACT:
The valve consists of a strip onto which two coplanar strips are welded separated by an opening. Production of the valve takes a strip onto which two strips are welded separated by a space. The valve obtained is welded onto a laminar, which forms part of the inflatable, with a hole which has to coincide with the valve opening. Next the first sheet is welded to a second laminar which forms the inflatable. The same process obtains a double valve with a single entry.
