ABSTRACT:
In a double-side lamination system having a thermocompression bonding device for laminating laminate films on both surfaces of a card by applying heat and pressure using a pair of heat rollers, a temperature measurement device for measuring temperatures of the heat rollers are provided, and whether the lamination system is in a double-side lamination mode in which laminations are carried out on both surfaces of the card, or in a single-side lamination mode in which lamination is carried out on one of the surfaces of the card, is automatically distinguished by comparing measured temperatures of the heat rollers at a predetermined time after turn-on of the power of the system with a predetermined reference temperature.
