Abstract

PURPOSE:To facilitate cutting of a foundation peripheral part by forming a recessed part by enclosing and sewing a peripheral part of at least one of two foundations and forming a pressure gas filled space. CONSTITUTION:Polymerized parts are formed by folding and bending foundations 36A and 36B along a folded crest line G, at first, and these polymerized parts are seamed to each other along broken lines J1 and J2. Thereafter, polymerized parts are formed by 12 folding and bending the foundations along a folded crest line H, and these polymerized parts are seamed to each other along broken lines M1 and M2. Finally, polymerized parts are formed by folding and bending the foundations along a folded crest line I, and these polymerized parts are seamed to each other along broken lines R1 and R 2. A bag body 26 is manufactured by laminating and polymerizing peripheral parts of the foundations 36A and 36B and seaming them to each other. At the time of seaming these peripheral parts, it is possible to facilitate the seaming by way of properly trim cutting the peripheral parts of the foundations 36A, 36B when required.
