The apparatus includes a support frame having a first clamping mechanism for clamping a first cable end portion movably positioned on one end of the support frame and a second clamping mechanism for clamping a second cable end portion positioned on the support frame proximate the other end. After the individual strands of the cable end portions are spliced together, the first clamping mechanism is moved away from the second clamping mechanism, stretching the spliced section of the cable end portions, drawing individual conductors together so that the spliced section of the cable end portions can be properly reinsulated.

Abstract: A method and apparatus for producing a stranded cable. The wire stretching step and annealing steps which have been performed independently prior to the twisting step in the field of stranded cable production are combined in the invented apparatus. The rotary element defines an annular space in cooperation with a shoe member such that the cross sectional area of the annular space decreases progressively. The roughened wire guided into the annular space via the shoe member is press molten and subjected to extrusion moulding to obtain a plurality of wires, which in turn are twisted together. Since the stretching and annealing are performed by a single apparatus, shop space conventionally required for device installation is reduced.

Abstract: A method for making steel wire cord from particulate iron oxides with the aid of a fiber-forming acrylic polymer is disclosed. A plurality of continuous filaments are first formed by wet-spinning an acrylic polymer spin dope in which particles of iron oxide are dispersed. The resulting filaments are drawn to increase their tenacity and then twisted to form a precursor cord. This is followed by exposing the precursor to a reducing atmosphere (e.g., a gaseous mixture of hydrogen and carbon monoxide) at a temperature in the range of from about 900.degree. C. to 1150.degree. C. for a period of about 3 to 8 minutes. Under these conditions, the iron oxide particles are reduced to the metallic state and the polymer in the precursor is pyrolized to carbon and by-product gases. The carbon diffuses into the resulting iron, and the individual metal particles sinter to form continuous steel wire cord having an essentially ferritic/pearlitic structure.

Abstract: A wire preforming assembly is fixedly mounted on a circular turntable having thereon a predetermined plurality of bobbins dispersed in an array to provide a predetermined plurality of wires to the assembly equally spaced around its periphery. The assembly and the turntable are coaxially aligned with and relatively rotating about a longitudinally advancing, mandrelled hose. The wires are being directed to the hose by the preforming assembly so that the hose pulls the wires with uniform equal tension and causes them to be simultaneously wrapped thereon in side-by-side parallel helical convolutions. The wire is directed in a helical path around the surface of a preforming tube of the assembly and is bent toward the hose as it is being wound thereon. The bending imparts a characteristic to the wire which causes it to naturally retain the desired helical shape around the hose.
