Nails(11)(11') are fixed with a constant distance along the drawn line of a bending window on the plate(12). Synthetic resin peices(1) (2) are made flexible in the heated silicon oil at 120 140 C. This temperature can be adjusted by the synthetic resin flexibility temperature. Moulds(3)(4)(5) are fixed on the both sides of the synthetic resin pieces inserted between the nails. Plate springs(6) (7)(8) are inserted in the holes(3a)(4a)(5a) along the moulds. A plate spring(10) is contacted on the plane portion of the resin pieces. The elasticity of the springs(6)(7)(8)(10) press the moulds and the synthetic resin pieces equally. This makes a fine bending plastic window after cooling.
