Estimating the term…
The invention specifies an apparatus for applying a film (7) to a substrate (2) by lamination. This apparatus has a heating device (12, 19), which makes it possible for different regions of the film (7) and/or the substrate (2) to be exposed specifically to different temperatures. It is thus also possible to process substrates or films which contain temperature-sensitive elements, e.g. security elements based on bacteriorhodopsin. For this purpose, the heating device comprises a plurality of heating elements (19) which can be activated separately, and therefore different regions of a heating surface (12) can be subjected specifically to different levels of heating power. In order to compensate for irregularities on the surface of the substrate or of the film, the apparatus may have a flexible mating surface (21) which is arranged opposite the healing surface and can be subjected to pressure pneumatically by way of a pressure chamber (22). Overall, this makes it possible to produce high-security documents with temperature-sensitive security features, the properties of which meet extremely stringent requirements relating to prevention of manipulation and forgery.

(canceled)
A method for providing a substrate with a film by lamination, comprising:
A document, comprising a substrate and a film connected thereto by lamination, said document being produced by a method comprising:
A document, comprising a substrate and a film connected thereto by lamination, wherein at least one of the film and the substrate comprises at least one temperature-sensitive element, the film and the substrate, in a region containing the temperature-sensitive element, being connected in a manner different from in a region not containing the temperature-sensitive element.
