The first pre-assembled component 10a located on the third conveying module 150C is also substantially maintained in the second posture.

In one embodiment, the first mover 140A and the second mover 140B can move synchronously. In other words, the process of moving the dialyzer body 11 from the first positioner 160A to the ring assembler 110 (or the first set of loading stations 170A) is the same as the process of moving the first pre-assembled component 10a from the ring assembler 110 (or the first set of loading stations 170A). The process of moving to the third conveying module 150C can be performed simultaneously/synchronously.

As shown in Figures 2E, 2F and 2F3, the second conveying module 150B can convey the fiber bundle unit 13 to the second positioner 160B. The second positioner 160B is used to adjust the fiber bundle unit 13 to the first posture. For example, the extending direction of the long axis of the fiber bundle unit 13 is substantially parallel to the X-axis. In the embodiment, the second positioner 160B includes the same or similar structure as the first positioner 160A to achieve the same or similar functions, which will not be described again.
