Abstract
A method for the manufacture of a high tension ignition cable wherein a tension member is passed through an extruder to form a settable plastic layer thereon. This extrusion takes place under conditions such that substantially no setting of the plastic layer occurs. Thereafter, winding a resistive conductor around the plastic layer to form a plurality of coils at least partially embedded in the layer. The coils are then coated with an insulation layer and a plastic layer is caused to set, thereby fixing the coils in position so that they do not move. The cable made by the foregoing process is also described.
Claims19
A method of making a cable comprising passing a tension member through an extruder to form a settable plastic layer thereon under conditions such that substantially no setting of said plastic layer occurs,
- thereafter, winding a wire around said plastic layer to form a plurality of coils at least partially embedded in said plastic layer,
- thereafter extruding an insulation layer over said coils, and causing said plastic layer to set.
