Abstract

Method of making a strip-shaped multiple electric conductor, comprising the steps of, providing a strip of electrically conducting material, applying a first layer of insulating material to one wide side of the strip and a second layer of insulating material to the other wide side of the strip, providing in the first layer along the strip at least one groove penetrating so far as to expose the conducting material, removing the exposed conducting material as far as the second layer, so as to form at least one longitudinal cavity in the strip, and filling the cavity and the groove with an insulating material.
