Abstract
A reverse stranding apparatus for the reverse stranding of conductors to produce cables or the like and to a method in connection with stranding and reverse stranding. The conductors are drawn from a distributor into a nozzle or equivalent through peripheral tubes circumferentially surrounding a central tube and being twistable about the central tube recurrently in opposite directions. To facilitate the passage of the conductor, a pressurized fluid is fed through the peripheral tubes upstream ends and into the peripheral tubes during the drawing of the conductors to produce oscillation, whereby the conductors passing through each peripheral tube remain substantially detached from the inner surfaces of the peripheral tubes.
