Press firmly. At this time, the surface temperature of the cooling roll (5) is set below the melting point of the fluororesin sheet and the sheet to be bonded, and the temperatures of the cooling roll (6) and the cooling roll (7) are lowered in stages. However, the multilayer sheets adhere to each other between chill roll (5) and chill roll (7). If it is necessary to apply rough heat, the tension can be increased and the rolled multilayer sheet can be subjected to a predetermined heat history to ensure complete adhesion.
