ABSTRACT:
A filament served bondable conductor is described. A metal wire is wrapped with an insulating yarn then suspended between two supports. After passing over the first support, the wire is immersed in a varnish, excess varnish is removed, and the varnish is cured in an oven before the wire passes over the second support. The wire is again suspended between two more supports. After passing over the third support the wire is immersed in an enamel, excess enamel is removed, and the enamel is cured to a non-tacky B-stage in the same oven. The wire can then be wound on a take-up reel until needed. The wire can be formed into coils and the coils heated to fuse and completely cure the enamel.
