ABSTRACT:
In an apparatus for cable manufacture, a cage strander rotates about a line axis at a chosen rotational speed. Bobbins supported by the strander dispense round conductors downstream of the cage strander. A forming apparatus downstream of the strander receives the conductors and forms them into many complementary segmented preshaped wires each having the desired cross-sectional profile in a final compact conductor. The conductors are positioned in a way that substantially corresponds to the orientations among wires in the final conductor. A first drive rotates the forming apparatus about the line axis substantially at the rotational speed of the strander. A second drive drives the forming apparatus. The drives are synchronized so that the conductors close about the core and cause the sides of adjacent wires to abut against each other to produce both the desired lay and a cable substantially without interstices between the wires forming the twisted conductor.
