Abstract
Abstract An inflatable assembly made from structural members of two-ply woven fabric coated on the outside with sealing material and having spaced apart interwoven connections. One ply is cut close to the interwoven connections to provide narrow flaps and at a distance from the interwoven connections to provide wide flaps. The narrow flaps are adhered to the wide flaps to prevent pulling out of the cut portions of the piles at the interwoven connections. Two or more structural members are assembled into an inflatable assembly by adhering together the ends of the wide flaps of overlapping structural members to form bulkheads in the assembly.
