ABSTRACT:
A plurality of strands (7) of sectorial cross-section is stranded around a central core such as an optical fiber conductor. First, a rigid type stranding machine is used to impart a spiral twist to each strand (7). Then, the twisted strand (7) is heat-treated or otherwise treated to remove any stress caused by the twisting. These strands are then fed to a planetary type stranding machine which provides a planetary motion in which the strands perform an orbital rotation around the optical fiber core of an optical conductor or conductors without rotation about its own axis, whereby the strands are stranded together on the optical fiber core.
