<p>A laminator assembly and method utilizes an endless belt (17a, 17b, 300) and roller arrangement to apply pressure to media (100) to be laminated and to convey the media in a controlled manner to heated pressure rollers (11a, 11b, 301, 307). In one feature of the invention, control nips can be provided on one or both sides of the heated pressure rollers so as to minimize or eliminate flutes or ripples in the media to be laminated. The control nips can be applied by plate assemblies (29, 30, 315) which create the control nip and also serve to gain control of the media to be laminated prior to the media reaching the heated pressure roller arrangement. In the case where the plate assembly is downstream of the heated pressure roller arrangement, the plates can serve to hold the media flat while it cools down. The endless belts apply a tapering and controlled pressure to the media prior to the media reaching the heated pressure rollers where lamination occurs. <IMAGE></p> |
