By adding a heating means (not shown) such as can be performed by adjusting the temperature at the time of pressurization.

The operation of the fourth molding apparatus 340 as described above is made independently of the operation of the third molding apparatus 330. For example, molding the second molding part of the window by the fourth molding apparatus 340 may be performed separately from molding the first molding part of the window by the third molding apparatus 330. Alternatively, the pressure applied by the fourth molding apparatus 340 to mold the second molding part of the window may be different from the pressure applied by the third molding apparatus 330 to mold the first molding part of the window. Alternatively, the time that the fourth molding apparatus 340 molds the second molding part of the window may be different from the time that the third molding apparatus 330 molds the first molding part of the window. Accordingly, the molding of the second molding part of the window by the fourth molding apparatus 340 is performed without being affected by the molding of the first molding part of the window by the third molding apparatus 330, thereby making it possible to form the second molding part of the window. It can shape | mold suitably for the characteristics, such as the shape. Therefore, by independent operation of the fourth molding apparatus 340, it is possible to mold the second molding portion of the window of better quality.
