てしていた。(Prior art) Conventionally, when a laminated film is manufactured by the T-die method, the viscosity of the extruded resin and the flow rate of the resin are different due to a difference in a kind of raw material resin and a difference in molding conditions. There has been a problem that uneven thickness of the film and various troubles at both edges of the film (for example, troubles such as poor adhesion at both ends due to poor cleaning at the time of resin switching) occur. In order to solve such a problem, conventionally, a deckle having an appropriate shape for each condition is exchanged to control the flow width of the resin. FIG. 2 is an overall view showing a conventional general T-die apparatus. Reference numeral 11 denotes a T-die main body. Deckels 12 are provided on both sides of the T-die for regulating the flow width of the resin. The deckle was changed due to the difference. Further, as an improved technique which facilitates the exchange of the deckle, for example, there is a technique described in Japanese Utility Model Application Laid-Open No. 58-79323. FIG. 3 is a view showing a two-stage deckle disclosed in the publication. Reference numeral 11 denotes a T-die main body, on both sides of which a deckle 12 is provided, and an upper deckle 12a and a lower deckle 1 are provided.
It was provided so as to be separable in a superposed form of 2b. Each deckle is supported by a separate support bar. Then, the lower deckle 12b was removed and replaced with another lower deckle 12b due to a difference in resin and a difference in molding conditions.
