Description
【００４８】
上記ヒータ５の下方位置には、このヒータ５の中心軸を挟んだＸ方向の両側位置に、それぞれ２つのローラ６，６、…が配設されている。この各ローラ６は、Ｙ軸を回転の中心軸として回転可能に構成されており、上記ヒータ５を通過することによって一体化したガラスパイプ２とガラスロッド３との一体化物（光ファイバ母材７）を、Ｘ方向に相対向した二対のローラ６，６，…で挟み込んで、この一体化物を下方に引き取るように構成されている。この各ローラ６，６の回転速度は変更可能に構成されており、これにより、一体化物のヒータ５からの引き取り速度を調整することが可能にされている。こうして一体化物のヒータ５からの引き取り速度を調整することにより、上記一体化物の外径を所定の径（目標外径）の光ファイバ母材７にさせるようにしている。[0048]
Below the heater 5, two rollers 6, 6,... Are arranged at both sides in the X direction across the central axis of the heater 5. As shown in FIG. Each of the rollers 6 is configured to be rotatable with the Y axis as a central axis of rotation, and an integrated product of the glass pipe 2 and the glass rod 3 integrated by passing the heater 5 (optical fiber preform 7 ) Is sandwiched between two pairs of rollers 6, 6,... Facing each other in the X direction, and the integrated body is pulled downward. The rotational speed of each of the rollers 6, 6 is configured to be changeable, which makes it possible to adjust the take-up speed of the integral from the heater 5. In this way, the outer diameter of the integrated product is made to be the optical fiber preform 7 of a predetermined diameter (target outer diameter) by adjusting the take-up speed of the integrated product from the heater 5.
