A method and apparatus for the application of moisture blocking compound to the interstitial spaces of a stranded conductor. The application of the compound is accomplished through the use of a cone die which regulates the amount of compound applied to the conductor.

Disclosed is a method and apparatus for continuously lubricating cable during continuous dry curing of cable insulation to reduce friction between the cable insulation and the dry curing apparatus, thereby eliminating cable oscillation and vibration to increase product quality and the speed of production.

Disclosed is a method for continuously lubricating cable during continuous dry curing of cable insulation and insulation shield to reduce friction between the cable surface and the dry curing apparatus, thereby eliminating cable oscillation and vibration and increasing product quality and the speed of production, comprising coating insulation compound pellets and insulation shield compound pellets with incompatible lubricant immediately prior to extrusion of insulation and insulation shield on to the cable.

The present invention relates to a method for preparing curable pellets of polyethylene and copolymers thereof for subsequent use in an extrusion coating process by mixing polyethylene pellets with a liquid curing agent at a temperature below the decomposition temperature of the curing agent and below the softening point of polyethylene and copolymers thereof.

A fault locator system for multiplex cable, which includes a bare wire and three insulated wires stranded together. The system includes the separation of the bare conductor from the insulated conductors on a rewind line and the applying of an electric field (electromagnetic field) or dielectric field around the insulated conductors so that one can, by a signal or a bell, alarm, buzzer or the like, locate the fault and stop the rewind line at the fault location. The apparatus of the system includes a rotating disc structure which contains electrical conducting guides through which each insulated strand of the multiplex cable passes and is tested for insulation holes or faults. A high voltage signal is placed on the electrical conducting guides for the insulated strands by means of a brush electrode, which sets up an electrical field surrounding the portion of the insulated strand in the guide. By means of a spark tester connected to each insulated strand, a fault in the insulation is detected as it passes through the surrounding electromagnetic field. The rotating disc, which is synchronized with the cable pull-out capstan or take-up machine, untwists the cable on the entry side and retwists it on the exit side. The apparatus of the present invention thus separates the insulated, plexed cables, checks continuously for faults as the cable passes through it, and then puts the cable back into its plexed state. In one embodiment (FIGS. 1-3) the rotating wheel or disc is free floating and is driven by the cable as the cable is drawn through it, while in the second embodiment (FIGS. 4 and 5), the disc structure is positively driven by an internal drive mechanism.

A process for selectively recovering vinyl halide insulation from mixed insulated wire scrap by selectively dissolving the vinyl halide insulation with a solvent at a temperature at which the solvent is a specific solvent for the vinyl halide and has no solvent effect upon other organic insulation material present in the mixed insulated wire scrap. The dissolved polyvinyl halide is recovered from solution in a dry granular state suitable for extrusion upon wire as insulation. The polyvinyl halide insulation is polyvinyl chloride, copolymers of polyvinyl chloride or mixtures thereof.

Insulated wire, cable, and the like, is stripped of its insulation without damaging the wire. The insulated wire is preferably cooled to a low temperature, rendered brittle, and then continuously passed over roller means to effect fracturing and removal of the insulation. The bare wire is continuously recovered in an undamaged condition and the particles of insulation recycled where necessary. Wire straightening is optionally provided for straightening the bent wire after the insulation is removed.
