The valve is comprised of a strip (1) on which are welded two coplanar strips (3, 4) separated by an opening (5). In order to fabricate the valve, a web (11) is used on which are welded two bands (12, 13), separated by a gap (5). The resulting valve (16) is welded onto a sheet (17) which is part of the inflatable body, is provided with an orifice (19) in registration with the opening (5) of the valve. Then, a second sheet (21) forming the inflatable body is welded to the first sheet. Said process provides for the production of a single-inlet double valve.
La valve possède une tirette (1) sur laquelle sont soudées deux tirettes coplanaires (3, 4) séparées par une ouverture (5). Afin de fabriquer la valve, on utilise une bande (11) sur laquelle sont soudées deux bandes (12, 13) séparées par un intervalle (5). La valve obtenue (16) est soudée sur une feuille (17) qui fait partie du corps gonflable, est dotée d'un orifice (19) qui doit coïncider avec l'ouverture (5) de la valve. Ensuite, on soude à la première feuille une seconde feuille (21) qui forme le corps gonflable. Ce procédé permet d'obtenir une valve double ayant une seule entrée.
