ABSTRACT:
A method of manufacturing insulated electric wire of the enamelled-wire type wherein an insulating sheath adhering to the wire is formed by extrusion of selected thermoplastics which are heated to a temperature above their melting-point, then pressed onto the wire while in a fluid state. The extrusion apparatus includes a gauging die with a compressing cone having an aperture angle of from 2.degree. to 20.degree., preferably 7.degree..
