Abstract
Based on a shape of gores of the Natural-Shaped Balloon, side edge parts of gores having a large width and a large length are connected to load tapes of a length equal to a circumferential length of a side edge part of the gores of the Natural-Shaped Balloon, in a state that wrinkles are formed uniformly and shortened on the side edge parts of the gores. As these gores are swollen out from between the load tapes from the beginning, the radius of curvature of the gores becomes small and the tension against the internal pressure of gas within a gas bag becomes small, so that higher pressure resistance is obtained. Further, a manufacturing method of the present invention is for connecting the side edge parts of the gores with the load tapes while shortening the length of the side edge parts. Thus, it is possible to efficiently manufacture this super-pressure balloon.
