Abstract
A hollow tubular structure having edges held in close proximity by residual compressive forces in the material forming the tubular structure is formed by first drawing a metal or metal alloy strip through a first die and forming an open tube section and then drawing the open tube section through a second die. The hollow tubular structures have particular utility in optical fiber communication cable constructions.
