Abstract: Disclosed is a method of making an insulated wire, the insulation of which can be easily removed from at least one location. The wire is covered at the desired location with a foil which does not adhere to the wire. The entire wire and foil are then covered with insulation. The insulation can be easily stripped from the wire at the location of the foil by cutting into the insulation at that location and peeling it off. Also disclosed is an insulated wire made by this method.

Abstract: An improved metering die is disclosed which comprises two non-rotatable parallel metering pins, at least one of which is resiliently mounted for movement in opposition to the other. Means for adjusting the resiliency of the opposition is also provided.A wire is immersed into a liquid resin and is passed through the metering die. The metering die removes excess resin and leaves a coating on the wire of precisely controlled thickness.

Abstract: A filament served bondable conductor is described. A metal wire is wrapped with an insulating yarn then suspended between two supports. After passing over the first support, the wire is immersed in a varnish, excess varnish is removed, and the varnish is cured in an oven before the wire passes over the second support. The wire is again suspended between two more supports. After passing over the third support the wire is immersed in an enamel, excess enamel is removed, and the enamel is cured to a non-tacky B-stage in the same oven. The wire can then be wound on a take-up reel until needed. The wire can be formed into coils and the coils heated to fuse and completely cure the enamel.

Abstract: A curing system is disclosed for continuously curing a resinous coating on an elongated member such as a wire. The wire passes through a curing chamber which contains a plurality of removable modules alternately positioned on opposite sides of the wire. Each module contains a source of electromagnetic radiation, such as an ultraviolet lamp, and an excess number of modules is provided. Each lamp can be turned on and off individually. If a lamp fails another lamp is turned on and the curing proceeds while the module containing the defective lamp is removed and the defective lamp is replaced.
