    • PURPOSE: A device and a method for molding a board having a double curvature are provided to avoid the thickness deformation of the board by gradually pressing the board with a bending deformation principal in a state of not restricting the board and to obtain a natural shape of a surface waveform of the board. CONSTITUTION: A molding tool includes two pairs of support punches and a central punch(39). The two pairs of support punches(36) are installed on a punch support(37) to support and bend a board(35). The central punch bends the board by pressurizing from an upper part in a square frame formed by the two pairs of punches. Herein, the center of the board is pressed by using the support and central punches. The board is bend along back/forth and right/left directions around the center of the board. The board is bent in the outside direction from the center and symmetrically right and left around the center of the board. Then, an edge of the board is bent in order.
