MOLDING DEVICE AND MOLDING METHOD

The purpose of the present invention is to make it p ossible to efficiently shape a reinforced fiber sheet and properly generate an interlayer slip. A molding device (1 ) is provided with: a mandrel (4) that has an arc-shaped cross section; a roller (5) that has a round-shaped cross section, is movable along a surface of the ma ndrel (4), and applies a pressing force to a material (10) to be molded placed on the mandrel (4); a gripping unit ( 3) that grips the material (10) to be molded on an outside of the roller (5) with respect to the mandrel (4) and app lies a tensile force to the material (10) to be molded; a roller driving unit that moves the roller (5) along the su rface of the mandrel (4); a gripping-unit driving unit (2) that moves the gripping unit (3); an d a control unit that synchronizes a position of the rolle r (5) and a position of the gripping unit (3) with each ot her to control the roller driving unit and the gripping-unit driving unit (2) so that the material (10) to be mold ed between the roller (5) and the gripping unit (3) is arr anged in a direction perpendicular to a vertical direction of the mandrel (4).
