    • A method of producing glass fiber comprising: driving a bottomed hollow cylindrical rotor to rotate at high speed around a vertical rotary shaft, said rotor comprising a bottom, a peripheral wall and an annular flange, said peripheral wall being extended upwardly from an outer peripheral edge of the bottom and provided with a large number of fine holes, said annular flange extending inwardly from an upper edge of the peripheral wall; falling molten glass to the bottom of the rotor; and ejecting molten glass through said fine holes by centrifugal force generated by the high speed rotation of the rotor, to form the molten glass into filaments, and to produce glass fiber; characterized in that molten glass is made to fall at a position on the bottom, said position being apart from an inner edge of said annular flange by at least 10 mm or more, and apart from an inner surface of said peripheral wall by not more than 75 mm, the bottom having a large thickness at the position.
    • 一种制造玻璃纤维的方法,包括:驱动有底的中空圆柱形转子围绕垂直旋转轴高速旋转,所述转子包括底部,周壁和环形凸缘,所述周壁从外周边缘向上延伸 并且设置有大量细孔,所述环形凸缘从周壁的上边缘向内延伸; 将熔融玻璃倒入转子底部; 并通过由转子的高速旋转产生的离心力将熔融玻璃喷射通过所述细孔,以将熔融玻璃形成长丝,并生产玻璃纤维; 其特征在于,使熔融玻璃落在底部的位置,所述位置与所述环形凸缘的内边缘分开至少10mm以上,并且除了所述周壁的内表面不超过 75mm,底部在该位置具有较大的厚度。
