Abstract
For laminating layers consisting at least in part of thermoplastic films, in particular for producing identification cards, or the like, carrying information and/or data, a method is proposed where the blank, after having been introduced between pressing dies, is initially subjected to the pressure and heat required for complete lamination of the blank. Heat dissipation is prevented during heating by the fact that cooling components are kept at a predetermined distance from the heating surfaces. During a subsequent transition from heating to cooling, the heating effect is terminated and cooling bodies are brought into contact with the pressing and heating components, for reducing the temperature of the completely laminated product.
