Abstract

The ion deposition web-fed engine includes a first fixed frame, a second frame pivotally mounted to the first frame, a third frame carried by the second frame for pivotal movement therewith and for movement in a transverse direction relative to the first and second frames. The third frame carries a print unit including an image cylinder for cooperation with an impression cylinder carried by the first frame. For servicing purposes, the second frame is pivoted relative to the first frame to provide access to the paper web, impression cylinder and image cylinder. Upon closing the second frame onto the first frame, the image cylinder defines an open nip with the impression cylinder. The print unit is movable linearly toward the impression cylinder to close the nip into a print condition.
