PURPOSE: To easily and accurately perform the initial adjustment of a die slit gap and to expand the adjusting range of the die slit gap while enhancing the controllability of the die slit gap due to a thermal displaceable actuator. CONSTITUTION: A pair of lips 22, 23 are constituted as movable lips and a manual operation type die bolt 28 is arranged to one movable lip 22 and an automatic operation type die bolt 30 due to a thermally displaceable actuator is arranged to the other movable lip 23 and the arrangement pitch of the manual operation type die bolt 28 is set smaller than that of the automatic operation type die bolt 30. |
