Abstract
An intermediate transfer film on which an image is printed is carried on a backing web and after is laminated to a substrate, such as an identification card. A lamination station uses heater rollers for the lamination process, and subsequent to the lamination station the backing web is guided to a take-up roller around a peel-off roller. The peel-off roller is supported in a heat insulating frame to minimize storing heat that increases the likelihood of flakes of the laminate material remaining with the backing web.
Claims1
For use in a printing and laminating assembly having a printer that prints on a layer carried on a backing web, and having a laminating station to heat laminate the layer to a card moving in a plane, the backing web being transferred to a take up roller subsequent to moving through the lamination station, the improvement comprising a peel-off roller and support frame assembly between the lamination station and the take up roller, the support frame comprising a unitary frame of heat insulating plastic material and having a cross member and a pair of spaced apart hubs depending from the cross member, the cross member being supportable on the assembly, the peel-off roller being rotatably mounted on the hubs and extending therebetween, the cross member being spaced from the peel-off roller to form an air gap over the peel-off roller, the peel-off roller engaging the backing web on a side thereof opposite from the layer, the peel-off roller being rotatably mounted in a frame, the peel-off roller being positioned relative to the take up roller so the backing web forms an angle of between 30° and 45° relative to a plane of movement of the card through the lamination station as the web moves across the peel-off roller, and the support frame supporting only the peel-off roller.
