<p>A line of prints has passed through a laminating machine so that a laminating film has been applied to both surfaces of the line. To enable individual prints to be torn off the laminating film is indented or perforated near to an edge of the line of prints. Tearing is then effected from the perforated edge to the other edge. The indentation or perforation of both films occurs downstream of their respective supply rolls.</p> |
