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.
