The method is to inject liquid raw resin, which will serve as the fixing resin, into the spaces formed between each bundled hollow fibers and between the hollow fibers and the inner wall of the cylindrical member, and then pour the raw resin from a predetermined fixing position. Conventionally, there has been known a method of fixing resin while preventing the outflow of the hollow fiber bundle by applying centrifugal force to the ends of the hollow fiber bundle to be fixed.

定する方法である。 Specifically, in this centrifugal resin fixing method, a cylindrical member loaded with a hollow fiber bundle is fixed to a rotor or its arm that rotates horizontally or vertically, and the end of the hollow fiber bundle is fixed with a resin. It is installed with a fixing jig assembled to prevent the liquid raw resin from getting wet from the end of the rotor, and is also installed in the center of the rotor, and is connected to the end of each cylindrical member and the resin supply pipe. The communicating resin containers are filled with liquid raw material resin, the rotor is rotated in this state, and the centrifugal force accompanying this rotation causes each hollow fiber end at which the liquid raw material resin is to be fixed from the resin container. The ends of the hollow fiber bundle are moved between the hollow fibers and between the hollow fibers and the inner wall of the cylindrical member, and held there until the resin is sufficiently solidified to fix the ends of the hollow fiber bundle in a predetermined position within the cylindrical member. This is a method of fixing in a liquid-tight or air-tight manner using resin.

ものが通常使用されていた。 The jig used for this method of fixing the ends of the hollow fiber bundle with resin is used when removing the cylindrical member whose ends are fixed with resin from the jig. , so that the inner wall of the jig that is in contact with it can be easily peeled off, or the solidified resin left inside the jig can be easily removed from the jig so that the jig can be reused. It is made of engineering resin that has releasability to the fixing resin, or it is made of metal such as stainless steel or steel, and is coated with a release agent that provides releasability to the fixing resin. were commonly used.
しかしながら、上述した従来の遠心式樹脂固定
処理に用いていた治具においては、次のような欠
点があつた。

て使用不可能となる場合が多かつた。しかも使用
不可能となるまでの使用回数、すなわち耐用回数
が少ない。 In other words, jigs made of engineering resin are easily scratched because they are made of polytetrafluoroethylene, and as they get scratched the more times they are used, the removability of the resin that has solidified inside the jig deteriorates, and eventually In many cases, it became unusable because sufficient removability could not be obtained. Moreover, the number of times it can be used before it becomes unusable, that is, the number of times it can be used is small.

際に困難を生じる場合が多かつた。 On the other hand, due to the structure of metal jigs, it is very difficult to uniformly coat a predetermined part with a mold release agent, and it is especially difficult to uniformly coat a mold release agent into the narrow holes through which the raw resin passes. However, as defects in the mold release agent coating tend to occur, good peelability from the solidified resin cannot be obtained, and when the cylindrical member is removed from the jig after the resin fixing process, there is Difficulties often occurred in removing the solidified resin.

It is necessary to form the attachment part of the shaped member with high precision, and to create a structure that allows the fixing resin that has solidified inside to be easily removed. This makes the structure complicated and requires advanced machining technology to manufacture. requested,
Moreover, the number of machining steps is large, and the production cost is high.
