ABSTRACT:
A method for producing information carriers in the form of cards, in particular credit cards, passes, identification cards, admittance cards etc., the laminating process including placing at least one card template which is to be sized, preferably a laminate consisting of a plurality of sized card layers, into a hollow mold and subjecting it to a simultaneous action of pressure and heat for a predetermined time. The material placed into the hollow mold is heated over at least one large area, as known per se by the use of heating plates, and in the peripheral, narrow, outer boundary region of the inserted material quantities of heat flowing off per se there are retained, blocked in, reflected and concentrated back onto the laminate template.
