Abstract

1359836 Heating extruded conductor coatings FUJIKURA CABLE WORKS Ltd 17 Sept 1971 [21 Sept 1970 7 Oct 1970 10 Feb 1971] 43448/71 Heading B5A [Also in Division C3] A covered wire is produced by coating a conductor by an extrusion moulding process with cross-linkable polyethylene or rubber, e.g. ethylene-propylene rubber, curing by heating the coated wire by ultrasonic waves and cooling the wire in a cooling zone. In Fig. 3, the ultrasonic wave oscillating device 5 is adjacent to the outlet of the crosshead die 2, comprising crosshead 2a, nipple 2b, die 2c and die holder 2d, of extruder 1, in which wire W is coated with the insulating material. In Figs. 1 and 2 (not shown), the ultrasonic wave source is placed in the heated zone of the curing tube into which the coated wire passes from the extruder, or in the cooling zone of the said tube.
