Abstract
In the making of cable with spaced conductor wires or tensile members in a non-circular jacket, the wires of member are maintained in desired angular positions within the jacket by guiding them through a core tube which is controllably rotatable within the extruder cross-head. The angular positions of the wires or members are monitored and upon their positions departing from the desired positions, the core tube is rotated in the appropriate direction to return them to the desired positions.
