<p>PROBLEM TO BE SOLVED: To provide the title T-die capable of sealing a resin leaked to the lower part of an inner rod and excellent in film forming properties. SOLUTION: In an inner deckle-shaped T-die for an extruder having an inner rod 16 for finally determining film width, a seal rod, 17 having the same length as the inner rod 16 and capable of sealing the resin leaked into the lip land 13 of the lower side of the inner rod 16 is provided on the downstream side of the inner rod 16. By confirming the position of the seal rod 17, the position of the inner rod 16 hidden inside to be not seen can be easily confirmed and, even if a film edge part is not seen, adjustment for preventing the dripping of a resin can be easily performed by operation on this side.</p> |
