ABSTRACT:
A method of making a hard multi-tubular structure which comprises; producing a flat hose fabric composed of a plurality of side-by-side abutting hoses, introducing uninflated foil tubes into each of the hoses of the fabric, the tubes being of substantially the same length as the length of the fabric, inflating the tubes for expanding the hoses into formed hollow sections, treating the fabric with a hardening material, and allowing a hardening of the hardening material and a setting of the fabric with the hoses in expanded condition. Therefollowing, the tubes are left after the setting of the hose fabric in the respective hollow sections free of any internal inflating pressure. Alternatively, the tubes may be withdrawn from the hollow sections after the setting.
