Royet, J M; Armer, R A

Improved multistrand Rutherford-type superconducting cable is produced in a flattened form with two layers of helically wound strands and in which the strands are alternately twisted about their lengths equally and in opposite directions to provide a flat cable with improved stability. In particular, the cable is made by guiding multifilament wire strands from spools on a rotating turret to a fixed tapered forming mandrel where they are wound diagonally around the mandrel and then rolled into a flattened shape. The spools are located around the periphery of turret and are rotatable about axes in a plane parallel to the turret to unroll the wire.
