The OVL molding apparatus described in Japanese Patent Publication No. 1994-242242 is known. This apparatus has a sheet-side chamber (upper chamber) and a substrate-side chamber (lower chamber) that are partitioned by a decorative sheet, and a suction table in which a ventilation hole is formed in the substrate-side chamber. It is installed and formed between the decorative sheet and the suction table while heating the decorative sheet with the heater provided in the sheet side chamber under the condition that the molding substrate is arranged on the suction table. The air in the closed space is vacuum-sucked through the ventilation hole formed in the suction table and the interior of the chamber on the seat side is pressurized as necessary, so that the decorative sheet causes the pressure difference between the seat-side chamber and the upper chamber. Is to be pressed and adhered to the outer surface of the molding substrate.

易い。In such an apparatus, since the decorative sheet is generally pressed against the molding base material only by the pressure difference,
There is a case where the pressing force of the decorative sheet on the side of the molding substrate is insufficient or there is a partial unevenness, and there are uneven steps provided on the outer surface or the curvature of the end or local portion of the outer surface is large. In that case, the decorative sheet cannot be completely adhered to the uneven portion and the curved portion, and thus adhesion failure is likely to occur.

As another example of the decorative sheet laminating apparatus, as described in, for example, Japanese Utility Model Publication No. 46-9276 and Japanese Patent Publication No. 60-58014, a decorative sheet is added to the rubber-like elasticity in addition to the above pressure difference. A vacuum press lamination molding apparatus has been proposed which is pressed by a film to adhere to a molding substrate.

いる。This apparatus 50 is schematically shown in FIG. 4 in which the molded state is illustrated. The box-shaped seat side chamber 1 in which the downward opening is closed by the rubber elastic film 14 is illustrated.
1 and a box-shaped substrate-side chamber 21 in which a suction table 22 having a vent hole 23 is installed in an upward opening, and the molding substrate 1 is arranged on the suction table 22. At the same time, after the decorative sheet S is set on the molding substrate 1 via an adhesive, the sheet-side chamber 11 and the substrate-side chamber 21 are clamped to form the rubber-like elastic film 14 and the suction table 22. A closed space is formed between the seat side chamber 1
While heating the rubber-like elastic film 14 by the heater 15 provided inside 1, the air in the closed space is vacuum-sucked through the ventilation holes formed in the suction table, and the inside of the seat-side chamber is moved as necessary. By pressing, the decorative sheet is heated and softened by the rubber-like elastic film while being pressed and adhered to the outer surface of the molding substrate.

It is removed to the outside through the passage 20 and the ventilation hole 25 of the suction table 22. In this case, if the air in the closed space is not sufficiently degassed, the rubber-like elastic film 14 comes into close contact with the side surface of the base material mounting jig 18, and the back surface of the molding base material 1 and the rubber-like elastic film 14 are adhered.
Even if air remains in a portion surrounded by the base material mounting jig 18 and the base material mounting jig 18,
Through the vertical groove-shaped ventilation passage 20 and the ventilation hole 25 of the suction table 22 formed in the side peripheral portion of the device, the air is promptly removed to the outside.
