ABSTRACT:
The invention provides a device for coating a conductor wire, the device comprising an enameling oven, the oven comprising a chamber through which the wire coated in an enameling varnish passes, and being provided for this purpose with a wire inlet and a wire outlet, and with means for heating the wire along its path within the chamber in order to evaporate solvent from the varnish and bake the varnish on the wire, the atmosphere inside the chamber having low oxygen content, the chamber further comprising a fan and an air feed inlet communicating with the chamber and servo-controlled to means for measuring the oxygen content. In the device, the fan and the air feed inlet are situated in distinct positions that are spaced apart from each other, the fan being situated between the solvent evaporation zone and the air feed inlet in such a manner as to entrain the solvent towards the air feed inlet so that the solvent is treated by combustion outside the zone in which the varnish is baked.
