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 bundle F of hollow fibers is placed in a dipping tank in which the sealing material C is stored. It is soaking. However, if the coating amount is too large, when the hollow fiber bundle F is pulled up from the dipping tank, the sealing material C drips and is hard to cure. Further, if the amount of the sealing material C is too large, it becomes difficult to loosen the material later, which leads to a decrease in productivity. On the other hand, if the coating amount is too small, the hollow fibers f that are not blocked by the sealing material C remain, causing a leak, and repair is required, so that the manufacturability also deteriorates. Therefore, it is necessary to keep the coating 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 chuck portion 7b receives the hollow fiber bundle F from a conveyor (not shown). After receiving this, 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 dipping tank 1 as shown in FIG. The end portion of the fiber bundle F is dipped in the dipping tank 1 from the lower end surface F1 thereof by a certain amount. 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 the descent stop signal d to the control circuit 7c, and the moving device 7 causes the hollow fiber bundle F to be moved.
Stop the descending operation of. The moving device 7 has a small time (1 sec
˜5 sec), after stopping, the hollow fiber bundle F is lifted and pulled up from the dipping 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 this application, while the sealing material C has sufficient fluidity, it is left standing in a horizontal position as shown in the enlarged view of FIG. By doing so, the sealing material C inside and outside the hollow fiber f gradually penetrates into the thick portion fa of the hollow fiber f. At this time, since the space between the hollow fibers f is smaller in volume than the inside of the hollow fiber f, the sealing material C between some hollow fibers f is reduced or disappears. After the above-mentioned standing, wait until the fluidity of the thermoplastic sealing material C almost disappears at room temperature, and then rub the impregnated portion F2 of the sealing material C in the hollow fiber bundle F with a finger or a loosening machine (not shown). As a result, as shown in FIG. 5, while one or several hollow fibers f are divided into blocks B, the sealing material C hardens and ends F are separated.
2 is sealed.

1 does not sufficiently enter the sealing material C between the dipping tank 1 and the dipping tank 1, so that the unsealed hollow fibers f remain.
It will need to be repaired. On the other hand, the lower end face F of the hollow fiber bundle F
If only 1 is dipped into the dipping tank 1 without being pressed, an unnecessarily large amount of the sealing material C adheres to the lower end face F1 to cause liquid dripping and the above-mentioned loosening process becomes difficult.

する。On the other hand, in this end sealing method, since the lower end face F1 is pressed against the porous body 2 impregnated with the sealing material C, an appropriate amount of the sealing material C impregnated in the porous body 2 adheres to the lower end face F1. To do. Therefore, since the unsealed hollow fibers f do not remain, the repair product is less likely to come out, and liquid dripping does not occur, which improves the manufacturability. 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. Therefore, regardless 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 allow the sealing material C to be impregnated therein and smaller than the diameter of the hollow fiber f.
In the case of gold steel, when the hollow fiber f has a diameter of about 500 μm, a mesh of about 40 to 80 mesh is used.
