ズル穴を有するプレート、所謂ブツシングプレー
トの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in plates with nozzle holes for molten glass filled boxes or bushings, so-called bushing plates, used for producing glass fibers, such as glass fibers or continuous glass filaments.
従来のブツシングプレートは、第１図に示す如
くブツシングプレート材料１に一定間隔に多数の
ノズル２を配列突設して成るもので、各ノズル２
は漏斗状のテーパ３ａと細い直管部３ｂとから成
る。 As shown in FIG. 1, the conventional bushing plate is made up of a bushing plate material 1 with a large number of nozzles 2 arranged and projected at regular intervals.
consists of a funnel-shaped taper 3a and a thin straight pipe portion 3b.
ところで、斯かるブツシングプレート４のノズ

果から判明した。 By the way, it has been found from the results of glass fiber spinning experiments that the flow of molten glass entering the nozzle 2 of the bushing plate 4 turns into a swirling flow after a while after spinning the glass fiber or the like.
しかし、上記のテーパ部３ａと直管部３ｂとか

抗が大きいので、ノズル２が変形し易く、ブツシ
ングプレートの寿命が短い等の問題があつた。 However, in the nozzle 2 consisting of the tapered part 3a and the straight pipe part 3b, the resistance of the spiral flow of molten glass to enter the taper part 3a is large, and the molten glass does not flow smoothly into the thin straight pipe part 3b. It is difficult to achieve a stable swirling flow state at an early stage. Further, since the resistance of the molten glass applied to the nozzle 2 is large, there are problems such as the nozzle 2 being easily deformed and the life of the bushing plate being short.
本発明は斯かる問題を解消すべくなされたもの
で、ノズルに流れ込む溶融ガラスを早期に安定し

のである。 The present invention has been made in order to solve such problems, and is a method for producing glass fibers in which the molten glass flowing into the nozzle is brought into a stable swirling flow state at an early stage, and the resistance of the molten glass applied to the nozzle is reduced. The purpose is to provide a bushing plate.

設けたことを特徴とするものである。 The bushing plate for manufacturing glass fibers of the present invention has a spiral shape on the upper part or the entire inner surface of the bushing plate material 1, which has a large number of nozzles 2 arranged and protruded at regular intervals, as shown in FIGS. 2 and 3, respectively. It is characterized in that a groove 5 is provided.

トの寿命が増長するものである。 In this way, the bushing plate 4' of the present invention,
4'' is provided with a spiral groove 5 on the top or the entire inner surface of each nozzle 2, so the molten glass flowing into the nozzle 2 flows along the groove 5 and immediately becomes a stable swirling flow. The spiral groove 5 reduces the resistance of the molten glass to the nozzle 2,
This prevents deformation of the nozzle 2 and extends the life of the bushing plate.

流動状態となつた。 However, when glass fibers were manufactured using the bushing plates of Examples 1 and 2 and the conventional example, in the conventional bushing plate, the molten glass entered the nozzle 2 after the start of spinning. While it took 45 minutes for the butting plate 4' of Example 1 to flow into the flow, it took 20 minutes for the bushing plate 4' of Example 1 and 15 minutes for the bushing plate 4'' of Example 2, which resulted in a stable swirl flow very quickly. It became a state of flux.
