Abstract: A laminating device for producing identification cards includes a press for glueing a number of foil sheets together; the press includes a lower press and an upper press. Each press is provided with a heating element, which is formed as a heating resistance element, and an insulation layer which is placed between the heating element and a metallic block which forms a portion of each press, to which a pressing force is applied. Each metallic block is cooled in cooperation with the insulation layer so that its temperature during the glueing and cooling process remains constant.
