| abstract | (57) [Summary] [PROBLEMS] A die capable of changing the lip opening of a die end to a tapered lip opening corresponding to an arbitrary film thickness, and furthermore, an optimal tapered lip opening online. Therefore, it is useful for stable production of thin films, and can contribute to improvement of film productivity. SOLUTION: A die for extruding a molten resin into a sheet shape, wherein at least one lip of the die can change a lip opening degree by its own deformation, and a lip end portion of the die can be changed. The lip opening to any position in the width direction can be changed, and the lip opening A at the lip end and the lip opening B at any position in the width direction from the lip end are expressed by the following equation (1). An extrusion die characterized in that the setting can be changed within a range satisfying (3). 1 ≦ A / B ≦ 5 (1) (In the formula (1), A is a lip opening degree at the lip end of the die, and B is an arbitrary position from the lip end. It indicates the lip opening, and the unit is mm.) |
