Abstract
The enamelling apparatus includes at least one assembly constituted by an applicator for applying varnish on a conductive wire and an associated enamelling oven, with the wire passing through both of them. The enamelling oven has a single chamber filled internally with radiant heater elements facing the path of the wire and the atmosphere inside the chamber is controlled to have an oxygen content that is low, and less than 6% . The apparatus is suitable for use in the production of an enamelled wire.
