The morphological appearance of the cylinders and of the laminates have been assessed by digital image processing performed during a number of production campaign of aluminum foils. The statistical analysis performed on the cylinders have shown that it is possible to evidence the modifications induced by the rolling operation. Such modifications have been found both in axial direction of the cylinders and in the longitudinal direction of the laminates. Yet, roughness measurements performed on the cylinders did not show any variation along the axial direction.
