PURPOSE: To easily and efficiently produce the spherical hollow bodies constituted of many faces of ≥3 faces, from the spherical hollow bodies of flat shapes to the spherical hollow bodies of a bobbin shape, oval shape or truly spherical shape by using plural sheets of equally shaped and divided sheets of n sheets, for example, ≥3 sheets, constituting the spherical hollow bodies.
CONSTITUTION: This process for production consists in producing the spherical hollow bodies constituted of plural sheets of ≥3 sheets of the equally shaped and divided sheets formed by disposing a constituting sheet 1, which is two folded with a sealant layer on the outer side, in such a manner that its fold (a) side exists inward, superposing respectively one sheet of two sheets of the constituting sheets 1, which are not two-folded, above and below the constituting sheet 1, in such a manner that the respective sealant layers exist on the inner side with each other, to form a constituting sheet group A and subjecting the constituting sheet group A to fusion sealing or fusion cutting sealing so as to comply with a closed curve from the upper side of the constituting sheet group A.
