ABSTRACT:
Method and apparatus for improving the performance of laminating protective plastic to a document using a machine of the type in which plastic laminating film from a roll is drawn over a guide member surface and between laminating pressure rollers by a film drive means wherein wrinkles that form naturally at the location of the guide member surface are eliminated by locating a vacuum means in the path of the film at or near the guide surface to create a generally uniform drag force across substantially the entire width of the film in opposition to the force drawing the film through the system.
