Laminating machine
Abstract
Abstract A laminating machine including a pair of cooperating heater roll assemblies and a pair of cooperating pull rolls, which is characterized by the heater roll assemblies comprising a hollow metal tube rotatably supported in a laminating machine and a heater non-rotatably disposed within the hollow tube, with the hollow tube being supported at the ends in planetary bushings. Tear blade means are provided adjacent the pull rolls for severing the protected document from the film supply means, with the tear blade means including a stripper plate for separating the film from the tear blade. The supply rolls of film are each supported on a pair of cross-rods in the laminating machine and tensioning brake means are associated with each supply roll to assure maintenance of proper tension of the films, thereby resulting in a smooth wrinkle-free lamination of film to the document to be protected.
