摘要
This gel reducing device (1) has a gel reducing mechanism (8) that reduces the gel present in a resin kneaded mixture and that is provided within a resin duct (5) through which the resin kneaded mixture flows. At least one throttle duct (10) having a smaller duct cross-sectional area than that of the resin duct (5) is provided to the gel reducing mechanism (8), and in order to enable the generation of an elongational flow at the kneaded mixture that flows through the throttle ducts (10), the draw ratio (S1/S2) of the throttle ducts (10) is set in a manner so as to satisfy a relationship of 25-180.
