Abstract

Une feuille de matériau de soufflet latéral (3) est pliée en deux, superposée en deux couches et interposée entre deux pans de matériau de panneau (1 et 2). Un des pans de matériau de panneau (1) est plié le long d'une ligne de pliure longitudinale (8) pour former les pans de matériau de panneau (1 et 2) ouverts et produire une surface ouverte formée sur les pans de matériau de panneau (1 et 2). Une des couches de matériau de soufflet latéral (3) est pliée le long d'une ligne de pliure longitudinale (8) pour former des couches de matériau de soufflet latéral (3) ouvertes ainsi qu'une portion de soufflet auxiliaire (7) et produire une surface ouverte formée sur les couches de la portion de soufflet auxiliaire (7). Un pan du matériau de soufflet de fond (4) est superposé sur les surfaces ouvertes du matériau de panneau (1) et la portion de soufflet auxiliaire (7). Le pan de matériau de soufflet de fond (4) et la portion de soufflet auxiliaire (7) sont scellés à chaud l'un à l'autre alors que les pans de matériau de panneau (1 et 2) et la feuille de matériau de soufflet latéral (3) sont scellés à chaud l'un à l'autre sur la largeur des pans de matériau de panneau (1 et 2) avec les surfaces ouvertes formées. Le pan de matériau de soufflet de fond (4) et au moins un des pans de matériau de panneau (1) sont scellés à chaud l'un à l'autre le long des pans de matériau de panneau (1 et 2) où les surfaces ouvertes restantes formées.
