ABSTRACT:
Enamelled wire is produced using almost solvent-free fusible resins. Molten resin is pumped from a supply reservoir against the direction of movement of the wire with part of the resin coating the wire. The raw wire is preheated to a temperature near the melting temperature of the molten resin. Excess resin is returned to the supply reservoir after the resin coating the wire has been calibrated to a predetermined circumferential dimension. The resin coating the wire is then hardened. The coating apparatus includes a raw wire guide, a demineralized water bath, an annealing furnace having a protective steam atmostphere, a cooling water bath, a wire preheater, an enameling stove, a heated resin reservoir, a resin applicator and a winding-on machine. The resin coating is applied under closed system conditions, thereby substantially reducing emissions.
