BALLOON ENVELOPE AND METHOD OF FABRICATING SAME Abstract of the Disclosure A balloon envelope (12) is disclosed which has the ability to minimize and isolate destructive tears, and which comprises a latticework of intercon- nected vertical and lateral reinforcing tapes (20, 32) which form open areas therebetween, and with a fabric panel (34) overlying and covering each open area. The fabric panels are sewn to the surrounding tapes in a manner such that there is no direct interconnection between adjacent fabric panels. The envelope is fabricated by a procedure wherein the vertical gores (22), which are each composed of a vertical array of the fabric panels, are initially formed by sewing adjacent side edges of adjacent panels to intermediate laterally directed tapes (32), and then sewing a ver- tical tape component (20a, 20b) along each side of the resulting array of panels. The vertical side edges of the thus formed gores are then sewn together to form a sphere-like configuration.
