Abstract
A slitting machine () includes a laminated film unwinding apparatus (), a release liner recovery apparatus (), a cutting apparatus (), and a plurality of polymer substrate strip rewinding apparatuses (). The laminated film unwinding apparatus () is operable to unwind a roll of laminated film () comprising at least a polymer substrate () and a release liner (). The release liner recovery apparatus () is operable to wind the release liner () that is released from the polymer substrate (). The cutting apparatus () is operable to cut at least the polymer substrate () along a machine direction to divide the polymer substrate into strips. The plurality of polymer substrate strip rewinding apparatuses () are operable to wind one or more strips of the polymer substrate () onto one or more rolls (). The slitting machine () is operable to carry out a method for forming rolls () of coated films ().
