ABSTRACT:
A manufacturing method for a sheet molded body having a desired three dimensional shape and an excellent quality of the design, which has no crease, by uniformly expanding a decorated sheet prior to molding, and closely contacting the decorate sheet to the surface of a male die. In the manufacturing method, the pressure at the front side of the decorated sheet is lowered relative to that at the back side. An arm means is then moved towards the decorated sheet from the back side of the decorated sheet so that the decorated sheet is inverted by increasing the pressure at the front side relative to that at the back side. The decorated sheet is then three dimensionally formed along the surface of the male die by, while pressing the male die from the back side and moving the arm means backwards, increasing the pressure at the front side.
