つ必要がある。Here, as a method of applying the sealing material C to the end M1 on the closed side, conventionally, the end face of the hollow fiber bundle F is placed in an immersion tank in which the sealing material C is stored. Immersed. However, when the amount of application is too large, when the bundle F of hollow fibers is pulled up from the dipping tank, the sealing material C drips and hardly hardens. On the other hand, if the amount of the sealing material C is too large, it will be difficult to unravel later, resulting in a decrease in productivity. On the other hand, if the application amount is too small, the hollow fibers f which are not closed by the sealing material C remain, causing a leak, and thus need to be repaired. Therefore, it is necessary to keep the applied amount of the sealing material constant.

端面Ｆ１に塗布される。Next, a method of sealing the lower end face F1 of the hollow fiber bundle F will be described. First, the moving device 7 of FIG.
The hollow fiber bundle F is received by the chuck portion 7b from a carrier (not shown). After the receipt, the moving device 7 lowers the hollow fiber bundle F in the axial direction and presses the lower end face F1 of the hollow fiber bundle F against the porous body 2 at the bottom of the immersion tank 1 as shown in FIG. The end of the fiber bundle F is immersed in the immersion tank 1 by a fixed amount from the lower end face F1. Due to the pressing of the hollow fiber bundle F, the measured value of the weighing device 4 increases, and eventually exceeds the second upper limit value W2. At this time, the control means 5 outputs a descent stop signal d to the control circuit 7c, and the moving device 7
Stop the descending operation of. The moving device 7 has a very short time (1 sec.
After stopping, the hollow fiber bundle F is raised and pulled up from the immersion tank 1 as shown in FIG. 1, and the sealing material C is applied to the lower end face F1.

２がシールされる。After the application, while the fluidity of the sealing material C is sufficient, the sealing material C is allowed to stand in a horizontal posture as shown in the enlarged view of FIG. Then, the sealing material C inside and outside the hollow fiber f gradually penetrates into the thick part fa of the hollow fiber f. At this time, since the space between the hollow fibers f, f is smaller in volume than the inside of the hollow fiber f, the sealing material C between some of the hollow fibers f, f decreases or disappears. After the standing, the flow is waited until the fluidity of the thermoplastic sealing material C almost disappears at room temperature, and the impregnated portion F2 of the sealing material C in the hollow fiber bundle F is rubbed with a finger or a loosening machine (not shown). Thereby, as shown in FIG. 5, while being divided into one or several blocks B for each hollow fiber f, the sealing material C is cured and the end F
2 is sealed.

Since the sealing material C does not sufficiently enter between the immersion tank 1 and the immersion tank 1, the unsealed hollow fiber f remains.
Repair is required. On the other hand, the lower end face F of the hollow fiber bundle F
If it is only immersed in the immersion tank 1 without pressing it, an unnecessarily large amount of the sealing material C adheres to the lower end face F1, causing liquid dripping or making the above-mentioned loosening step difficult.

I do. Therefore, since the unsealable hollow fiber f does not remain, the degree of release of the repaired product is reduced, and no dripping occurs, so that the productivity is improved. In particular, even when the diameter of the hollow fiber bundle F is large, the sealing material C impregnated in the porous body 2 adheres to the lower end face F1 irrespective of whether the hollow fiber bundle F is at the center or near the outer periphery. The sealing material C adheres evenly and evenly.

The size of the pores of the porous body 2 is preferably large enough to impregnate the sealing material C and smaller than the diameter of the hollow fiber f.
If the diameter of the hollow fiber f is about 500 μm, a steel of about 40 to 80 mesh is used.
