生産性の向上が図れる。The guide wheel for an optical fiber manufacturing apparatus according to the present invention is constructed as described above,
When the compressed air is ejected from the gas ejection holes 11 by, for example, opening the compressed air 13, the compressed air is directed in the rotation direction of the guide wheel 1 (the winding direction of the optical fiber 6) and collides with the side surface of the disk portion 5. The rotational force is always applied to the wheel 1 in the direction in which the optical fiber 6 is wound, and the wheel 1 is freely rotated until the optical fiber 6 is wound. Is provided, it is easy to rotate and does not cause slack in the traveling optical fiber 6, so that the optical fiber 6 does not come off from the guide roller 1 during wire drawing, so that the wire can be hooked smoothly. I can do it. Moreover, since the guide wheel 1 is constantly applied with a rotational force in the winding direction of the optical fiber 6 during the wire hanging, the optical fiber 6 comes off from the guide roller 1 even if the traveling speed of the optical fiber 6 is made higher than before. Never
Since the drawing speed is increased, the productivity of the optical fiber manufacturing apparatus can be improved.

For example, one having no round hole 8 may be used, or one having an arm structure may be used instead of the disk unit 5 having the round hole 8.
Further, as shown in FIG. 2, it is also possible to provide a structure in which collision fins 14 for receiving gas are provided radially on at least a surface of the disk portion 5 on which gas is blown. In this case, for example, compressed air ejected from the gas ejection holes 11 of the gas conduit 2 collides with the collision fins 14, so that the guide wheel 1 always more effectively always moves in the winding direction of the optical fiber 6. Rotational force can be applied, and the effect obtained by the configuration shown in FIG. 1 can be more effectively enjoyed.
