T-die for extruding a thermoplastic film (23) having no edge bead portions at opposite side edges of the extruded thermoplastic film, including deckle plugs (6) each fitted in the manifold (2) and the die slit (5) so as to extend from the manifold to the die slit along their each end portions for blocking molten resin flowing along their end portions, the deckle plugs each having a guide surface (7) formed at the inner end thereof for guiding the molten resin so that the latter flows from the manifold to the die slit, having the flow component of the widthwisely outward direction of thermoplastic film to be extruded. |
