A laminating apparatus is disclosed which has a loading slot for facilitating the loading of a web through a nip located between a supply and takeup spindle. An inboard support carries the inboard end of the supply and takeup spindles and the laminating rolls, and a spaced outboard support carries the other end of the laminating rolls. The outboard support is formed with a supply aperture aligned with the supply spindle, a takeup aperture aligned with the takeup spindle, and an interconnected threading slot corresponding to the path of the laminating web through the laminating nip between the supports.

Laminator and loading system therefor

A method and apparatus for laminating a protective overcoat carried on a web to an image carrying medium is particularly useful for covering an image carrying medium having a large area. A hot roller and an actively cooled cold roller form a nip through which the web and image carrying medium advance in a juxtaposed relationship. A temperature differential is created across the layers of the web and medium to promote adhesion between the surface of the protective overcoat and the image while preventing lamination artifacts such as curling and rippling. Postwrap and prewrap angles are used to enhance control of artifacts and assist in post lamination separation of the overcoated image carrying medium from residual web material.
