Abstract:
A method of producing melt-bonding wires containing at least one electrical conductor, comprising the steps of:(a) providing at least one electrical conductor having a layer of insulation thereon, the layer of insulation being selected from the group consisting of lacquer, varnish and enamel;(b) supplying meltable plastic material to a fusion chamber where the meltable plastic material is melted to produce a melted plastic material, the meltable plastic material is selected from the group consisting of aliphatic, aliphatic-aromatic, cyclo-aliphatic and aromatic polyamides; aliphatic, aliphatic-aromatic, cyclo-aliphatic and aromatic co-polyamides; and aliphatic, aliphatic-aromatic, cyclo-aliphatic and aromatic polyesters with a melting temperature of 150.degree. C. to 400.degree. C. and are supplied in a form selected from the group consisting of powder, granular and strand, wherein the supplying step includes detecting a fluid level of the melted plastic material in the fusion chamber and adjusting the fluid level to a predeterminable value by metering the supply of the meltable plastic material to the fusion chamber;(c) drawing the at least one electrical conductor having the layer of insulation through the melted plastic material to provide a calibrated meltable bonding layer thereon to thereby produce a melt-bonding wire; and(d) cooling the melt-bonding wire.
