  • Process and apparatus for producing a laminate, comprising at least one polymer film with information and at least one substrate, for further processing for forgery-proof documents
    Patent number: 6986823
    Abstract: A process and an apparatus for producing a laminate, comprise at least one polymer film with information and at least one substrate, for further processing for forgery-proof documents, in which, in the first processing station, a supporting film is delaminated on a first side of the polymer film, after which a substrate is laminated on by an adhesive and subsequently exposed to a crosslinking-active radiation, and in which a laminate led out from the first processing station is fed to a second processing station, and the supporting film is delaminated on a second side of the laminate, after which a substrate is laminated on by an adhesive and subsequently exposed to a crosslinking-active radiation.

  • Process and apparatus for producing a laminate, comprising at least one polymer film with information and at least one substrate, for further processing for forgery-proof documents
    Publication number: 20010052387
    Abstract: The invention relates to a process and an apparatus for producing a laminate, comprising at least one polymer film with information and at least one substrate, for further processing for forgery-proof documents, in which, in the first processing station (31), a supporting film (23) is delaminated on a first side of the polymer film (17), after which a substrate (18) is laminated on by an adhesive and subsequently exposed to a crosslinking-active radiation, and in which a laminate (44) led out from the first processing station (31) is fed to a second processing station (51), and the supporting film (23) is delaminated on a second side of the laminate (44), after which a substrate (19) is laminated on by an adhesive and subsequently exposed to a crosslinking-active radiation.
