ケル12bと交換してしていた。(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. 3 is an overall view showing a conventional general T-die apparatus. Reference numeral 11 denotes a T-die main body, on both sides of which a deckle 12 (integrated deckle) for regulating the flow width of the resin is provided. The deckle was exchanged due to differences and differences in molding conditions. In addition, as an improved technique for easier exchange of deckles, for example,
There was one described in Japanese Utility Model Laid-Open No. 58-79323. FIG. 4 is a view showing a deck for a T-die disclosed in the publication, and 11 is a T-die main body, with deckles 12 on both sides thereof and an upper deckle.
The two decks 12a and the lower deckle 12b were provided so as to be dividable (two-stage deckle). Each deckle
12a and 12b are each supported by separate support rods. Then, only the lower deckle 12b was pulled out together with the support rod and replaced with another lower deckle 12b due to a difference in resin and a difference in molding conditions.
