A flat die has an inlet (2) for supplying a molten resin from an extruder to the die therethrough, a hollow portion (3) so formed as to permit the molten resin supplied to spread in widthwise directions, and an outlet (7) for discharging the molten resin therethrough as spread in the widthwise directions, wherein an accommodating portion (12) and rotatable bodies (20,22) are formed between the hollow portion (3) and the outlet (7). Rotatable bodies (20,22) have an outer periphery substantially in the form of a true circle in cross section and substantially the same widthwise length as the outlet (7) and are rotatably disposed within the accommodating portion (12) with an axis thereof extending in the widthwise direction. <IMAGE> |
