結果糸切れ、糸の太さにばらつきが生じていた。(Problems to be Solved by the Invention) By the way, when the bushing plate 5 is used to discharge and spin glass fibers, if the bushing plate 5 is exposed to molten glass at a high temperature of about 1200° C. for a long time, the problem shown in FIG. As shown, the yarn gradually sagged and deformed downward into a spherical shape, resulting in yarn breakage and variations in the thickness of the yarn.

A number of glass introduction holes are provided in each recess, and a spinning hole is formed through the bottom of each glass introduction hole to form a nozzle.

も大幅に減少することになる。(Function) The bushing plate configured as described above is exposed to high-temperature molten glass when glass fibers are spun from each nozzle for a long time, but since it has reinforcing ribs on the top surface, it is prevented from hanging down and It does not deform into a spherical shape. Therefore, thread breakage is significantly reduced, and variations in thread thickness are also significantly reduced.

が無いからに他ならない。(Example) An example of the bushing plate for manufacturing glass fiber of the present invention will be described with reference to FIG. 1.2. 10 is a bushing plate material made of 10% platinum-rhodium alloy with a width of 100 mm, a length of 250 mm, and a thickness of 4 mm.
Concave portions 11 having a short diameter of 40 w in length and 2 mm in depth are formed in parallel, and a reinforcing rib 12 having a low width is formed around the concave portions 11 . Inside each recess 11, the base outer diameter is 4.5 μm,
100 glass introduction holes 13 with a tip outer diameter of 2.2 mm were drilled in a staggered arrangement at 511 intervals, totaling 400 glass introduction holes 2.
A spinning hole 3 with a diameter of 1.6 mm is drilled through the bottom of the nozzle 4.
The bushing plate 16 of the embodiment was obtained by continuously discharging and spinning glass fibers for a long time using the bushing plate 5 of the conventional example.
There was very little deformation compared to , and there was also very little variation in the thickness of the threads. This is simply because the bushing plate 16 of the embodiment has the reinforcing ribs 12 on the upper surface, so that it hardly deforms even if exposed to high temperature molten glass for a long time.

代わることのできる画期的なものといえる。(Effects of the Invention) As detailed above, the bushing plate of the present invention does not undergo thermal deformation downward into a spherical shape even when glass fibers are spun for a long period of time, and therefore the glass fibers spun through spun glass fibers do not break. It can be said to be an epoch-making product that can replace conventional bushing plates, as it has the advantage of eliminating the occurrence of variations in thread thickness.
