This is accomplished by unwinding the outside layer of film until it meets the remaining film layer end, and cutting this unwound layer so that it is even with the remaining film end. Upon completion of thi
38、s procedure, the outer film becomes the inner film and the inner film becomes the outer film, and thus provides proper film orientation for dispensing. is spread over two film layers and wound onto the feed 3.8.2.4.1 Marking of film.
