An aluminium foil rolling method comprising the steps of taking two strips of aluminium, bringing facing surfaces of the two strips into contact with one another and subjecting the two strips to a first pack rolling operation, thence subjecting the same two strips to a second pack rolling operation whilst maintaining the two strips in substantially the same registry as when the first pack rolling operation was carried out. Advantageously, following the first pack rolling operation, the two strips are coiled together onto a common coil in order to assist in maintaining their registry for the second pack rolling operation. In an embodiment, a release material is applied to the facing surfaces of at least one of the strips prior to bringing them together for the first pack rolling operation, and a further amount of release material, less than that applied before the first pack rolling operation, or even a zero amount, is applied between the two pack rolling operations. |
