ABSTRACT:
A method and apparatus for stranding with changing lay directions (SZ-stranding) utilizes an elongated cylindrical member which is driven with changing rotational sense on which the conductors are wrapped and supplied to a stranding disk at one end. The cylindrical member serves the purpose of stranding and is held under an axial tensile stress at its ends during the stranding process. The cylindrical member is also twisted to provide a torsional stress.
