As shown in FIG. Therefore, the hollow shaft 13 and the upper guide member 23 of the flyer 11 and the hollow shaft 13 and the upper guide member 23 of the flyer 12 are moved in opposite directions to each other in the X direction. As a result, the hollow shaft 13 of the flyer 11 moves to the position facing the shaft center 2a of the upper second bobbin 2, and the hollow shaft 13 of the flyer 12 moves to the position facing the shaft center 3a of the lower first bobbin 3 move. Thereby, while rotating the flyers 11 and 12, the monofilament M of each bobbin 2 and 3 is continuously drawn out. In this way, the linear body supply device 10 of the present embodiment can continuously feed out the monofilament M from the two bobbins 1 , 2 and 3 , 4 .

In addition, this invention is not limited to the above-mentioned embodiment, In the range which does not deviate from the summary of this invention, it can deform|transform and improve suitably. The linear body of the present invention may be wound around a bobbin, and is not limited to the above-mentioned monofilament, and may be a tape, a wire, a rope, or the like. In addition, in the present embodiment, the monofilament is supplied in a state where the bobbin is placed on a cart that can be transported from the outside, but the present invention is not limited to this. For example, the linear body supply device itself may have a Spool placement part. Furthermore, in the present embodiment, the configuration in which the linear bodies from the first bobbin and the second bobbin are continuously supplied has been described, but the present invention is not limited to this, and for example, the movement of the flyer may be enlarged. The range is increased, and the number of detection parts is increased to continuously supply linear bodies from three or more bobbins. For the detection of the splices of the monofilament, in addition to the detection method using a limit switch, for example, a transmission-type photoelectric sensor including a light-emitting part and a light-receiving part can be used to detect by transmission and blocking of visible light and infrared rays. Monofilament connector. In addition, the joint portion of the monofilament can also be detected by strain and load using a load sensor.

Then, as shown in FIG. 7 , in the initial state, the hollow shaft 13 of the flyer 11 and the upper guide member 23 that guide the monofilament M of the upper bobbins 1 and 2 and the monofilament M of the lower bobbins 3 and 4 are guided. The hollow shaft 13 of the flyer 12 and the upper guide member 23 may be arranged at the same position in the X direction. The first bobbin 1 on the upper side and the first bobbin 3 on the lower side are arranged at the same position in the X direction opposite to the Z direction. In this case, when the monofilament M of the first bobbins 1 and 3 is used up, the hollow shaft 13 of the flyer 11 and the upper guide member 23 move in the same direction as the hollow shaft 13 and the upper guide member 23 of the flyer 12 .
