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.
