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 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 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.

A stranding unit for a stranding machine has a stranding axis and a cage in which a number of baskets are arranged for receiving a number of reels having a strand material wound thereon. The stranding unit is characterized in that a stand is arranged which has a frame which extends around the cage in a circumferential direction around the stranding axis. The cage is mounted on the frame by a number of frame bearing elements and is rotatable around the stranding axis. As a result of the circumferential bearing, centrifugal forces are particularly efficiently distributed and absorbed by the frame during operation. In an advantageous further development, a plurality of basket are also mounted in a similar manner within the frame. The stranding unit as a whole is furthermore constructed such that it can be operated at a particularly high rotational speed.

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.
