生ずる。2. Description of the Related Art A bushing for forming a fiber is provided with a number of nozzles projecting from the bottom of a boat-shaped vessel made of Pt or a Pt alloy into which a molten fiber material is to be charged. The fiber-forming bushing is configured so as to have a fiber shape at the tip of the fiber. A method of attaching a nozzle to a bottom plate in such a bushing for forming a fiber is described in JP-B-45-2329 and JP-B-59-125.
No. 265. That is, FIG.
As shown in FIG. 4, a stud-shaped nozzle element 4 is formed by integrally integrating a foot portion 1 and a frusto-conical portion 3 having a step portion forming a large-diameter surface 2. The nozzle element 4 is shown in FIG. The foot 1 is locked in a hole 6 having a diameter of about 2 mm formed in the bottom plate 5 as shown in the figure. In this locking, a Pt solder for welding is used as a washer 7 having a thickness of about 0.2 mm. But at this time,
The washer 7 is used alone as shown in FIG. 5 and is positioned as shown in the left two rows of FIG. 6 and locked as shown in FIG. 7, or as shown in FIG. As shown in FIG. 9, the nozzle element 4 is aligned and locked as shown in FIG. 10, and the nozzle element 4 is locked in all the holes formed in the bottom plate 5 in this manner.
The bottom plate 5 and the periphery of the nozzle element 4 are heated to melt the washer 7 so as to be totally integrated. Thereafter, as shown in FIG. 11, a hole is formed at the center of each nozzle element 4 to form a bushing for forming a fiber. However, according to such a conventional technique, when locking the nozzle element 4 to the bottom plate 5, the nozzle element 4
Caulking the tip of the foot 1
When this caulking is performed, the accuracy of the caulking is poor due to the presence of the washer 7 between the nozzle element 4 and the bottom plate 5, and the degree of adhesion between the washer 7 and the nozzle element 4 and the bottom plate 5 varies, and the center position of the nozzle element 4. Deviation occurs.
For this reason, the alignment state of the nozzle element 4 after the heat welding becomes poor, and when the nozzle element 4 is actually used because the tip of the nozzle element 4 is unevenly formed in the later drilling of the nozzle element 4, inconvenience occurs at the time of forming the glass fiber. Results. Also, since the washer 7 is arranged around the hole in the bottom plate, the molten Pt solder flows around the hole in the bottom plate during heat welding, so that it does not enter the hole and is used for welding in the thickness direction. Insufficient portions are likely to occur, resulting in durability problems.
