PCT No. PCT/FR81/00119 Sec. 371 Date May 4, 1982 Sec. 102(e) Date May 4, 1982 PCT Filed Sep. 16, 1981 PCT Pub. No. WO82/01159 PCT Pub. Date Apr. 15, 1982.According to the method of the invention there is wound, around a hollow body (1) and in substantially contiguous turns, a flexible strip (2), the latter strip being fixed onto the hollow body. The strip is of a material, the tensile limit of which is in excess of that of the material of which the hollow body (1) is made, and when wound around the hollow body, a tension is applied thereto which is sufficient for the stresses which may develop within the body and the winding of the strip (2) to reach their permissible maximum limits at substantially the same time, when the hollow body is used under pressure.
