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 device for imparting a torsional force onto a wire has a base and a support mounted so as to be rotatable with respect to the base around an axis of rotation. The axis of rotation coincides with a wire path extending through the base and the support. Further, a wire clutching device is mounted on the support and adapted to engage at a wire guided along the wire path, and a rotation mechanism is provided which is adapted for rotating the support with respect to the base.

A flyer bow providing reduced drag during a wire processing operation is provided. The flyer bow may include an elongate arcuate body having a middle portion, and first and second end portions at opposite ends of the middle portion. The elongate arcuate body may be configured to be rotated about an axis of rotation, the middle portion may include an inner surface, an outer surface, a leading edge, and a trailing edge, the inner surface and the outer surface may cooperate to form a cross section, and at least one centerline of the cross section may include a radius of curvature substantially equal to a distance between the elongate arcuate body at the location of the at least one centerline and the axis of rotation.

An apparatus for producing an assembly of filamentary elements that are wound together in a helix includes a twisting device, a preforming device, and an assembling device. The twisting device is structured to twist at least first and second filamentary elements individually, such that each filamentary element is twisted separately from another filamentary element, to produce at least first and second twisted filamentary elements. The preforming device, which is arranged downstream of the twisting device, is structured to preform each of the twisted filamentary elements individually into separate preformed helixes, to produce at least first and second preformed helixes. The assembling device, which is arranged downstream of the preforming device, is structured to assemble the preformed helixes into an assembly.

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.
