A coil winding apparatus includes: a core rod feeding unit configured to feed a string-shaped core rod from a core rod nozzle; a core rod drawing unit configured to draw out the core rod; a wire rod feeding unit configured to feed a wire rod towards the core rod; a rotator capable of rotating about the core rod nozzle; the guide member provided on the rotator, the guide member being configured to clamp, with the core rod, the wire rod that has been fed from the wire rod feeding unit; and a rotating unit configured to rotate the rotator to rotate the guide member together with the rotator so as to revolve the wire rod around the core rod in a vicinity of the core rod nozzle.

A method for making a suspension cable to a desired length is provided. The method includes providing an initial pin hole on a tab of a socket associated with the cable. The method includes stretching the cable to a desired percentage of a rated breaking strength of the cable. The method includes measuring a length of the cable. The method includes determining a position of a final pin hole to be formed on the tab based on the measured length of the cable and a predefined tolerance. The method includes creating the final pin hole at the determined position.

A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. Once the potting compound in at least a portion of the cavity has transitioned sufficiently to hold the filaments at a desired level, tension is placed on the tensile-member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing. The invention can be applied to single fittings having multiple cavities and to multiple fittings having only one cavity per fitting.

To provide a metal wire and an electric wire of high mechanical strength and high ductibility that have sufficiently increased ductibility as well as sufficiently increased mechanical strength. A metal wire manufactured at least by being subjected to an extension in which a metal wire is extended in an axial direction, and having a hardness distribution in which hardness decreases toward a specific peripheral portion from a central portion in a cross-section orthogonal to axis, whereby a softened peripheral portion becomes to show a good malleability as well as a high resistance to cracking, so as to attain an improvement of mechanical strength and ductibility.

Provided are a steel cord and a single steel wire having excellent straightness quality for reinforcing tire and a method of manufacturing the steel cord and single steel wire.

Wire products, such as round and flat wire, strands, cables, and tubing, are made from a shape memory material in which inherent defects within the material are isolated from the bulk material phase of the material within one or more stabilized material phases, such that the wire product demonstrates improved fatigue resistance. In one application, a method of mechanical conditioning in accordance with the present disclosure isolates inherent defects in nickel-titanium or NiTi materials in fields of a secondary material phase that are resistant to crack initiation and/or propagation, such as a martensite phase, while the remainder of the surrounding defect-free material remains in a primary or parent material phase, such as an austenite phase, whereby the overall superelastic nature of the material is preserved.
