PROBLEM TO BE SOLVED: To provide a braid supply device being the device for supplying a braid support to a spinning nozzle in which the braid support is hard to get twisted up and superior process stability can be obtained in the production of a porous hollow fiber membrane.SOLUTION: A braid supply device 210 is provided for supplying a braid support 110 to a spinning nozzle 220 for spinning to apply a film-forming solution forming a porous membrane layer in an outer circumferential surface of a hollow braid support 110. The braid supply device 210 has a storage container 120 for storing the braid support 110, a guide member 214 provided on the storage container 120, and tensioning means 216 provided between the guide member 214 and the spinning nozzle 220 and applying tension to the braid support 110 drawn out from the storage container 120. The braid support 110 is drawn out from the storage container 120 toward the guide member 214, and supplied to the spinning nozzle 220.SELECTED DRAWING: Figure 11 |
