One-way valve for inflatable bodies and processes for producing said valve and incorporation of the valve to the inflatable body

摘要

The valve consists of a strip -1- onto which two coplanar strips -3, 4- are welded separated by an opening -5-. Production of the valve takes a strip -11- onto which two strips -12, 13- are welded separated by a space -5-. The valve obtained -16- is welded onto a laminar -17-, which forms part of the inflatable, with a hole -19- which has to coincide with the valve opening -5-. Next the first sheet is welded to a second laminar -21- which forms the inflatable. The same process obtains a double valve with a single entry.
