Zusammenfassung:	PURPOSE:To provide a dry-wet spinning method capable of being simply incorporated in a conventional spinning device, excellent in the coagulated liquid flow-controlling property, the raw liquid mass-passing property, the fiber- forming operability, etc., and giving fibers having good qualities, by employing a specific spinning device. CONSTITUTION:A coagulating solution fed from a coagulating solution inlet 8 into a coagulating tank 2 is allowed to flow down together with a coagulated fiber bundle 6, and the flow rate is adjusted with a cylindrical coagulated solution flow rate adjusting valve 9 which comprises a rubbery elastic material having an elasticity of 3-50kg/cm , and its opening diameter is changed by external pressures by applying an external pressure from a vacuum.pressure port 5. The coagulating solution is further allowed to flow down, separated from the coagulated fiber bundle at a direction-changing guide 7 below a spinning cylinder 10, and subsquently discharged.
