MULTILAYERED METAL LAMINATE AND PROCESS FOR PRODUCING THE SAME

摘要

An adhesive-free multilayered metal laminate having a g iven thickness which is obtained by bonding a metal sheet ha ving a thin metal film on a surface thereof to a metal foil w ithout using an adhesive; and a process for continuously pro ducing the laminate. The process comprises the steps of; setting a metal sheet on a reel for metal sheet unwinding; se tting a metal foil on a reel for metal foil unwinding; unwin ding the metal sheet from the metal sheet-unwinding reel and activating a surface of the metal sheet to thereby form a fi rst thin metal film on the metal sheet surface; unwinding th e metal foil from the metal foil-unwinding reel and activati ng a surface of the metal foil to thereby form a second thin metal film on the metal foil surface; and press-bonding the activated surface of the first thin metal film to that of th e second thin metal film so that the first thin metal film fo rmed on the metal sheet is in contact with the second thin me tal film formed on the metal foil.
