Abstract:
Process for rolling aluminum foils includes: providing first and second laminates each having two aluminum foils overlapped one to another between which a lubricant is interposed; lubricating one face of one laminate between the first and second laminate; coupling the first laminate with the second laminate obtaining a double laminate. The lubricated face is a contact face between the first and second laminate; or it is a non-contact face between the first and second laminate, in this case being provided the intermediate steps of winding the double laminate obtaining a wound double laminate having n coils; partially separating the wound double laminate by unwinding, by one coil, both the aluminum foils of one of the first and second laminate, obtaining an at least partially wound double laminate having an end portion constituted by a respective portion of both the aluminum foils of only one of the first and second laminate.
