Beschreibung
Zusammenfassung:	The present invention discloses a method and apparatus for applying high solids enamels to wire wherein the enamel is heated to lower its viscosity to below about 200 cps, the heated enamel is then passed through a discrete, enclosed passageway in a first felt pad. The wire to be coated is then drawn between the first felt pad and a second felt pad in contact with the first felt pad. The wire is passed substantially perpendicular and in front of the discrete passageway of the first felt pad when it is coated with the enamel. The enamel is then formed uniformly and circumferentially about the wire as it exits the felt pads and cured in a curing oven.
