<p>PROBLEM TO BE SOLVED: To control temperature within a narrow temperature region, and consequently obtain a favorable adhesion by a method wherein at least one temperature out of temperatures of pressure rollers, of laminating films and of a heat source and the temperature at the finish of contact bonding are detected so as to control the temperature of the heat source on the basis of these temperature detected. SOLUTION: In a machine frame 11, pressure rollers 12 and second pressure rollers 13 are provided and infrared heaters 18 for heating laminating films F, each of which leaves an upper laminating film roll 16 and reaches the pressure roller 12, are equipped. In front of the infrared heaters 18, the sensor 20A of a temperature before contact bonding for detecting the temperature of the laminating film F before entering the pressure roll 12 or of the pressure roller 12 is provided. Further, between the pressure rollers 12 and the second pressure rollers 13, the sensor 20B of a temperature after contact bonding for detecting the temperature of the surface of the upper side laminating film F leaving the pressure roller 12 is provided. The outputs from both the sensors 20A and 20B are inputted to a temperature controlling device so as to control the temperatures of the infrared heaters 18 in response to the output sent from the temperature controlling device.</p> |
