PROBLEM TO BE SOLVED: To provide a molding device for a sheet in which a wide sheet can be produced by utilizing an existing T-die and structure is novel. SOLUTION: In the molding device for a sheet, molten resin is extruded into the shape of a sheet from a T-die fitted to the tip of an extruder. This sheetlike molten resin is finished to the sheet having prescribed thickness by a polishing roll arranged on the outlet side of the T-die. This T-die is a coat hanger die having a taper manifold 12 in which molten resin is guided obliquely toward the end part of a lip 14 from the central part having an introduction port 11 of molten resin extruded from the extruder. An extension die 7 is provided on both sides of the T-die. The extension die 7 has both a straight manifold 71 which is communicated with the terminal end of the taper manifold 12 and guides molten resin parallel to the lip 14, and a lip 72 of the same length as the straight manifold 71. |
