Abstract: A method of and apparatus for extruding an article of uniform cross-section, the article including a thermoplastic material and at least one cable for inhibiting stretch of the article. The cable is supplied to a respective tube and is conveyed between upstream and downstream ends. The thermoplastic material may be supplied to the downstream end of the tube. The thermoplastic material is brought together with the cable to embed the cable within the thermoplastic material, thereby forming a composite extrudate. The tube is configured to at least hinder movement of loose windings of the cable from the downstream end towards the upstream end, which may prevent or at least reduce incidence of “birdcaging”.

Abstract: A headset can include a cable structure connecting non-cable components such as jacks and headphones. The cable structure can include several legs connected at a bifurcation. An extrusion process can be used to manufacture legs of a multi-segment cable structure. As material is processed by an extruder, one or more system factors of the extruder can be dynamically adjusted to change a diameter of the resulting leg (e.g., to provide a smooth leg having a changing size). Once the leg is extruded, portions of the leg can be reformed to create undercuts used to connect the legs at a bifurcation region. In some cases, an extrusion process can be used to construct a jointly formed multi-leg cable structure having an integral bifurcation region and split.

The cord includes an internal layer of M wires, M having a value from 1 to 4, and an external layer of N wires. The cord is rubberized from within in situ. That is, during manufacture of the cord, the cord is rubberized from inside. According to the method, the internal layer is sheathed with rubber or a rubber compound by passing the internal layer through an extrusion head, and the N wires of the external layer are assembled around the sheathed internal layer to form a two-layer cord rubberized from the inside. The rubber is an unsaturated thermoplastic elastomer that is extruded in a molten state, and preferably is a thermoplastic styrene (TPS) type of thermoplastic elastomer, such as an SBS or an SIS block copolymer, for example.

Abstract: A pre-twisted cable pair and a method for processing such pairs into an electrical cable having improved electrical and mechanical properties is disclosed. At least one insulated wire for transmitting electrical signals is pre-twisted prior to pairing with another insulated wire. As the pre-twisted wires are paired by a conventional double-twist machine which imparts back-twist, the detrimental electrical effects caused by irregularities in the individual wires are cycled over a very short distance, resulting in a cable pair having lower structural return loss, near-end crosstalk, and insertion loss than wires paired without any pre-twist. These pre-twisted wires may be united into a jacketed electrical cable by a continuous-extrusion jacketing process in which an optimal dielectric constant is maintained around each individual cable pair.
