PROBLEM TO BE SOLVED: To stably extrude a molten resin sheet in a molten resin supply device equipped with a die head for extruding a thin molten resin sheet. SOLUTION: The die head 10 of a molten resin supply device has a supply passage 12 and an extrusion passage 13 having a slit-shaped extrusion orifice 13a formed at the leading end thereof and a synthetic resin material supplied from the supply passage 12 in a molten state is extruded as a thin molten resin sheet 41 from the extrusion orifice. A heater 29 is provided to either one of the leading end half parts 10a, 10b becoming both sides of the extrusion orifice of the die head and controlled so that both leading end half parts become same in temp. When a plurality of die heads are arranged so that the extrusion orifices of them approach each other parallelly, the heater 29 is pref. provided to the leading end half part not arranged in close vicinity to other die head 15 among the respective leading end half parts of each of the respective die heads. Rollers 25a, 25b bonding respective extruded molten resin sheets may be provided. |
