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 detachable flyer bow system, apparatus and methods of using the same are provided. The systems each comprise a base having a longitudinal recess with an inner lateral dimension that is greater than the outer lateral dimension and a front lateral dimension that is smaller than the rear lateral dimension, an end block attachable to the end of the flyer bow with a recess engagement portion to slidably engage the longitudinal recess of the base. The base may have an opening to allow at least a portion of the end block to clear the opening for the inward insertion of the end block into the base, or the outward removal of the end block from the base. Methods for securing a flyer bow to a wire twisting machine, methods of attaching a flyer bow to an end block, and flyer bows in combination with end blocks are also provided

A stranding element (V) includes a stationary storage container (2) for the material to be stranded, and at least one rotating guiding device (1, 5, 6, 6a) for guiding the material to the stranding region (3) substantially parallel to the rotational axis of guiding device (1, 5, 6, 6a). The guiding device (1, 5, 6, 6a) is rotatably mounted in support structure (10), in particular in bearing arrangement (L). The bearing arrangement (L) lies completely within the circle of rotation of the material, and is secured to support structure (10) via a retaining arrangement (H) extending from the bearing arrangement (L) radially outwards beyond the circle of rotation of the material, and axially spaced from the guiding device (1, 5, 6, 6a). The retaining arrangement (H) has a passage that opens temporarily to allow the material to pass through in the circumferential direction and that follows the circle of rotation of the material.

A power paying-off cradle consisting of power paying-off component and framework. In the framework is a cavity with an upper opening; a wire tension balance mechanism is installed in the cavity; a displacement wheel is installed on the wire tension balance mechanism, and a position detector of the displacement wheel is installed on the inner side wall of the framework; a turning wheel is installed on the front top of the framework; a thread hole is installed in the front of the framework; wire on the paying-off spool enwinds the turning wheel and the displacement wheel successively and passes through the thread hole. The wire tension balance mechanism has damping effect on the displacement wheel. When the tension of the displacement wheel is greater than or less than the damping force, the displacement wheel moves in order to ensure consistency of the tension or the strain of wire.

The cable coiling device automatically coils heavy-duty electrical cable into a coiled bundle having a predetermined coil diameter. This device matches the over/under coiling method used to manually coil cables that eliminate unnecessary twists and knots in cables. The cable coiling device has a first roller and a second roller that is angularly offset from the first roller. The angular offset adds a twist to the cable as it passes between the rollers. The device maintains the first and second rollers at a predetermined distance away from each other so that the cable does not slip out of the opening between the rollers. When the coil exits the rollers, the resulting cable is coil bundled and has a specific predetermined coil bundle diameter. Guide wheels positioned at specific locations guide the cable through the device, which prevents cable looping before and after the cable passes through the rollers.

An improved system for handling delicate linear media and in particular to a method and apparatus for winding delicate linear media such as superconducting wire or tape or optical fibers onto a spool. A combination of direct closed loop control and media routing design facilitates the handling of the delicate media without causing damage. The axial tension in the linear media may be closely controlled during winding by means of feedback control loop using tension measurements to control the rotation speeds of the wind-from and wind-to spools. Further, during winding, the delicate linear media is only exposed to large radius bends with no reverse bending. Finally, output devices and features, commercial or otherwise, made possible by delicate linear media handling are revealed. This includes advanced SC devices and features.
