  • Method for making laminate sheets with flexible hinges for binding into security documents
    Patent number: 8926779
    Abstract: A hard laminate sheet with flexible hinge for binding into a security document is provided. Hard synthetic material layers are overlaid, sandwiching a flexible material layer having a hinge portion configured for separation from the hard synthetic material layers, and an affixing portion configured to become affixed to the hard synthetic material layers, upon lamination of the overlaid layers. The overlaid layers are laminated to form a laminate sheet having an embedded hinge affixed to the hard synthetic material layers. Score cuttings are made along a score line coinciding with an inner hinge edge on a hinge side which is then flexed until the hard synthetic material layers break along the inner hinge edge. Residual laminate layers are separated from the hinge side to expose the hinge portion of the flexible material.
