シヨンフイルム成形装置。[Claims for Utility Model Registration] (1) In an inflation film forming apparatus in which an annular air ring outlet is provided adjacent to and outside of a molten resin annular outlet of a molding die, on the downstream side of the air ring: At approximately the height of the film network, at least one annular airflow pressure adjustment chamber for preventing bubble swelling is formed concentrically with the annular outlet on the outer periphery of the bubble, and the annular airflow pressure adjustment chamber is located downstream of the bubble. At least two tapered truncated conical cylindrical guides, each having a side diameter close to the diameter of the annular air outlet and having a larger diameter toward the upstream side, are arranged adjacent to each other in a hierarchical manner at a predetermined interval. An inflation film forming apparatus characterized in that it is formed between the guides. (2) Utility model registration claim 1, in which the two annular airflow pressure adjustment chambers for preventing partial bulging of the bubble are formed by the three tapered truncated conical cylindrical guides arranged vertically and hierarchically. 2. Inflation film forming apparatus as described in Section 1.
