である。(1) As shown in FIG. 2a, when the protrusion 5 is formed by plastic working with the punch 4 and the conical depression 6 is formed, and then the punch 7 is punched in to form the spinning hole 8, the punch 7 may be slightly misaligned. The tip of the nozzle 9 is not driven straight, and the thickness of the nozzle 9 becomes uneven as shown in FIG. 2b. Therefore, when glass fiber is discharge-spun using the spinning hole 8 of such a nozzle 9, the fiber may break midway or the thickness of the thread may vary, which impairs quality.
