Abstract
A method and apparatus for forming a cable which has a supporting member that is provided by an extruder with helically extending grooves or chambers that proceed in changing directions for the acceptance of light waveguides characterized by synchronously rotating the cable elements proceeding an extruder for applying the supporting member and also following the insertion point for the light waveguides. The light waveguides are inserted at a position which is an even-numbered multiple of the distance between reversing points of the chambers of the supporting members from the output of the extruder so that the direction of the chambers at the extruder and at the insertion point, respectively, proceed in the same direction.
