DETAILED DESCRIPTION OF THE PREFERRED AND ILLUSTRATED EMBODIMENTS Turning now in detail to FIG.
1 of the appended drawing, therein illustrated is a coating system embodying the present invention, wherein two lengths of bare wire 10 are continuously withdrawn from supply spools 12 and conveyed through the system (by means not shown).
Each wire passes through an initial coating subsystem, consisting of an electrostatic fluidized bed unit 14, in which a particulate thermoplastic coating material is deposited on the wire, an oven or heat tunnel 16, in which fusion of the particles is effected, and a cold chamber 18, in which the fused resin is solidified to produce an insulating coating.
They thereafter pass about idler pulleys 20, 22, with the latter disposing the wires 10 in closely spaced proximity to one another, in which relationship they move along parallel travel paths.
The two insulated wires are simultaneously exposed to a cloud of electrostatically charged particles in the unit 24, and are subsequently heated to an elevated temperature to effect fusion.
This is most desirably accomplished in a tunnel 26 utilizing infra-red heaters, so as to concentrate the effect on the exterior of the assembly and thereby avoid undue softening of the previously formed insulating coatings.
Finally, the wire assembly is drawn through a cooling device 28, to solidify the resin of the outside coating and produce the finished cable, generally designated by the numeral 38.
As will be appreciated, to ensure effective deposition of the charged particles, the wires 10 will be maintained at ground potential (by means now shown), in accord with standard electrostatic coating practices Typical of the electrostatic fluidized bed coating apparatus that can be utilized is that which is disclosed and claimed in U.
