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.
Claims3
An optical fiber cable comprising:
- a substantially cylindrical tubular structure having a desired diameter and a generally longitudinally extending seam defined by spaced apart edges in close proximity;
- said structure being formed from a metal or metal alloy strip;
- said edges being placed in said close proximity by forces within said metal or metal alloy forming said tubular structure;
- said forces being created by initially forming said strip into an open tubular section having a minor diameter less than said desired diameter, a major diameter greater than said desired diameter and two legs forming an opening and subsequently forming said open tubular section into said substantially cylindrical tubular structure;
- and
- at least one optical fiber within said tubular structure.
