An automated lamination system for transferring an image to a print medium includes a photoconductive drum bearing a toned image on an electrostatic outer surface thereof. A dual purpose, heated lamination roller is moved to a first lamination position adjacent the drum to define a first nip between the drum and roller. The first nip in part defines a path for an image transfer web, and forces a thermally activated adhesive layer on the web against the drum. The image on the drum surface is embedded in the heated and softened adhesive layer as the web is advanced under pressure through the first nip. The dual purpose roller is later moved to a second lamination position adjacent a second lamination roller, to define a second nip therebetween. The second nip is configured to receive an image transfer substrate in registry with the latent image embedded in the adhesive of the web. The substrate and web are advanced through the second nip under heat and pressure, which forces the substrate against the adhesive layer and causes the substrate to adhere to the adhesive. A separation roller assembly spaced from the second nip along the path separates the web from the substrate so that the image embedded in the adhesive layer is borne by the image transfer substrate. The substrate is further processed through an optional inline deglossing station, while the web is rewound to align the remaining adhesive thereon with the drum for the transfer of another image.

An electrographic copying apparatus for transferring a toned image from an electrostatic carrier to a substrate, the apparatus comprising: an image transfer web; means for moving the web along a path past the electrostatic carrier; a first lamination roller movable between first and second lamination positions wherein the roller is positioned adjacent the electrostatic carrier in the first lamination position whereby pressure is applied by the roller against the electrostatic carrier to laminate the image to the web as the web is moved along the path past the carrier, wherein the roller is spaced from the carrier in the second lamination position; a second lamination roller spaced from the electrostatic carrier and along the path so that when the first lamination roller is moved to its second lamination position the first and second lamination rollers form a nip across the path for laminating the substrate to the image-bearing web as the web is advanced along the path; and means for separating the substrate and image from the web.
