Abstract: A method of making various insulated conductor sizes during a transformer coil winding process by slitting and bonding insulating sheet materials and foil sheet conductor into a composite foil conductor/insulation. The method includes folding the composite into a substantially U-shaped length having a central portion between two leg portions with each leg portion having a free end. The method also includes folding the leg portions of the "U" inwardly to a position substantially parallel to the central portion of the "U" to bring the free ends of the leg portions into opposing relation to provide a folded insulated foil conductor having a two-conductor thickness surrounded by insulation. Provision is also made for increasing the cross-sectional area of the conductor.
