An inline mixing device ( 53 ) is constituted of a sulzer mixer ( 160 ) disposed in an upper stream and a static mixer ( 170 ) disposed in a downstream. An additive supplied through an orifice ( 150 a) passes through the sulzer mixer ( 160 ) disposed in the upstream. As the sulzer mixer ( 160 ) is superior in dividing the flow, the additive is uniformly dispersed in a dope pipe ( 152 ). Thereafter, the additive passes through the static mixer ( 170 ). As the static mixer ( 170 ) is superior in reversing the flow, the additive and the primary dope are further stirred and kneaded. The inline mixing device ( 53 ) uses the two different kinds of mixers for effectively mixing the additive and the dope while taking advantages of each mixer.
