<p>In the formation of an electrolaminate made up of a core of insulating material webs with a high purity electrolytic copper foil on at least one side of the core, for use as a circuit board in electronic equipment, the web of insulating material and the copper foil are led from supply rolls to a laminating machine in out-of-contact relation. Prior to its introduction into the laminating machine, the copper foil is heated to the temperature of the laminating operation so that it is at its maximum thermally expanded length when it contacts the insulating material webs. Further, dust is removed from the copper foil as it enters the laminating machine. The webs and copper foil are moved at the same speed through the laminating machine. After pressing the electrolaminate in the laminating machine, it is moved through a cooling device. Subsequently, the electrolaminate can be wound in a roll or cut into individual lengths.</p> |
