Abstract

PURPOSE:To maintain the outside diameter of rodlike glass material at a fixed valve by making press., constant, to be applied to molten glass at the outflow opening of a crucible according to a change in outside diameter of the material extruded, thus making the flow rate of the glass constant. CONSTITUTION:By lowering left 7 molten glass 4 falling from crucible 2 through outflow opening 3 is formed into rodlike glass material 5 while being supported by support rod 6 of lift 7. The quantity of light screened by material 5 is detected with detector 12, and a change in quantity of light detected is converted into an electric signal with outside diameter measuring monitor 13. According to this signal, regulator 14 for oxygen to be introduced into crucible 2 is controlled to make press., constant, to be applied to glass 4 at opening 3, whereby the flow rate of glass 4 is held constant to continuously produce glass material 5 of a predetermined diameter.
