Zusammenfassung:A method for reducing gel in a polymer kneaded compound flowing in a polymer flow duct includes flowing a polymer kneaded compound in a polymer flow duct to a gel reduction mechanism including a gel reduction member having one or more through holes defining a squeezing flow path having a flow path cross-sectional area smaller than the polymer flow duct. The squeeze ratio S1/S2 of the squeezing flow path is 25 to 177.8, where S1 is a flow path cross-sectional area of the polymer flow duct and S2 is a sum total of flow path cross-sectional area of the squeezing flow path, to generate an extensional flow in the kneaded compound.
