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に一定間隔に前後左
右に多数のノズル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３
ｂとから成る。また第２図に示す如くノズル２が
２段のテーパ部３ａ，３ｂとこれに続く細い直管
部３ｂとから成るものもある。 As shown in FIG. 1, a conventional bushing plate is made up of a bushing plate material 1 with a large number of nozzles 2 arranged and protruding from the front, back, left and right at regular intervals.
Each nozzle 2 has a funnel-shaped taper 3a and a thin straight pipe part 3.
It consists of b. Furthermore, as shown in FIG. 2, there is also a nozzle 2 consisting of two stages of tapered parts 3a and 3b and a thin straight pipe part 3b that continues therefrom.

中間に位置する直管部３ｂでは溶融ガラスの流速
線P′が平行化して、溶融ガラスの流れが乱れてし
まう。 By the way, such bushing plates 4, 4' are
Since the nozzle 2 has the straight pipe portion 3b, the flow of the molten glass is once disturbed. That is, for the bushing plate 4 of FIG. 1, as shown in FIG. 3, the flow velocity line P of the molten glass up to the tapered part 3a of the nozzle 2 and after exiting the straight pipe part 3b of the nozzle 2 forms a parabola. Although they look similar, the flow velocity line P' of the molten glass becomes parallel in the straight pipe section 3b located between the two, and the flow of the molten glass becomes turbulent.
この為、吐出紡糸されるグラスフアイバー等が
途中で切断したり、糸の太さにばらつきが生じた
りして、品質不良のものが多く発生した。 For this reason, many of the glass fibers and the like that were discharge spun were cut in the middle, and the thickness of the yarns varied, resulting in poor quality.
本発明は斯かる問題を解消すべくなされたもの
で、溶融ガラスがノズルを流動した際、流速線の
変化が生じないようにしたガラス繊維製造用ブツ
シングプレートを提供せんとするものである。 The present invention has been made to solve this problem, and aims to provide a bushing plate for producing glass fibers that prevents changes in the flow velocity line when molten glass flows through a nozzle.
本発明のガラス繊維製造用ブツシングプレート
は、第４図に示す如くブツシングプレート材料１
に一定間隔に多数配列突設されたノズルが、直管
部の無い２段のテーパ型のノズル２′になされて
いることを特徴とするものである。 The bushing plate for producing glass fibers of the present invention has a bushing plate material 1 as shown in FIG.
The nozzle 2' is characterized in that a large number of nozzles protrudingly arranged at regular intervals are formed into a two-stage tapered nozzle 2' without a straight pipe section.
このように本発明のブツシングプレート５で

太さにばらつきが生じることも無い、品質良好な
ものが得られる。 In this way, in the bushing plate 5 of the present invention, the large number of nozzles 2' are of a two-step tapered type without a straight pipe section, so that when the molten glass flows through the nozzles 2', as shown in FIG. Thus, the flow velocity line P does not change, and the molten glass flows smoothly without any turbulence. Therefore, glass fibers etc. that are discharge spun are not cut in the middle, and there is no variation in the thickness of the yarn, and good quality can be obtained.

However, there was no such problem in the bushing plate 5 of the example.
