Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a film laminating apparatus capable of preventing an occurrence of a warpage like seal gull shape in a metal sheet in the case of cooling the film after heating the film laminated on the surface of the metal sheet. SOLUTION: In the film laminating apparatus, a primary heater 4, a laminator 5, a secondary heater 6 and a cooler 20 are sequentially disposed along a pass line of the metal sheet S. In this case, a plastic film f is laminated on the metal sheet after heating by the primary heater. In this case, as the cooler, an air cooler 21, a mist air injector 22 and a cooling tank (water tank) 8 are sequentially disposed along the pass line after heating a film laminated metal sheet S'. Thus the film laminated metal sheet is gradually cooled. |
