A strander apparatus includes a disk and a plurality of cradles, each of the cradles includes a reel and a cradle shaft, the cradle shaft extending in an axial direction from the disk. Each reel dispenses cable. The strander includes a main shaft, wherein the cradles are disposed on the cradle shafts radially about the main shaft. Planetary gears are disposed between the main shaft and the plurality of cradle shafts. The strander operates in one of a planetary mode and a rigid mode. In the planetary mode, while the main shaft rotates, the planetary gears are engaged to rotate each of the plurality of cradles on the respective cradle shafts. In the rigid mode, the planetary gears are disengaged.

A machine for manufacturing cables includes a winch that includes a tube, which includes at least a pulley, a reducer and an input shaft to the reducer in its interior. A system for attaching the reducer includes two concentric bearings. An outer bearing is attached to the reducer and the tube, and an inner bearing is attached to the pulley and outer bearing, such that the pulley is supported by the inner bearing and by bearings of the input shaft of the reducer.

An apparatus for detwisting wires or cables wound in spools, includes two coaxial shafts, inserted one inside another and kinematically independent, of which a first shaft is connected to a first motor and is adapted to support, by rotating it about a rotation axis, one spool, and a second shaft is connected to second motor and supports, by rotating it about the rotation axis, a detwisting cage, which is adapted to rotate about the spool. The apparatus further includes at least one take up guide for the wire/cable, which is connected to a third motor in order to rotate about the rotation axis of the cage, oscillating toward the guide and/or away from it, and elements for coordination of the rotation speed of the first shaft with the rotation speed of the take up guide.

A machine for manufacturing cables includes a rotor tube inside which is a motor. The machine also includes four rods attached to the tube. The rods are arranged so as to follow secant lines of the wall of the tube and include two mutually parallel plates. Each plate is connected to the four rods. The four rods are arranged such that they exert a force on the wall of the tube towards the inside of the tube in order to compensate for the effect of centrifugal force. The motor is positioned between the plates.

A wire fabrication apparatus includes a number of fluid channels, each fluid channel configured to receive a first portion of a corresponding wire of a number of wires and including a fluid flowing in a first direction therein. A twisting mechanism is configured for attachment to second portions of the number of wires, the twisting mechanism being configured to draw the number of wires from the number of fluid channels in a second direction opposite to the first direction and to twist the number of drawn wires. A controller controls twisting mechanism to form a twisted wire, including controlling the twisting mechanism to draw the number of wires from the number of fluid channels in the second direction and to twist the drawn wire.
