ABSTRACT:
An apparatus in which a glass rod is inserted into a spinning oven to perform spinning and glass fiber yarn is drawn out at a shutter located in the lower end of the spinning oven, comprising a timer for measuring a time from the start of heating of the glass rod inserted into the spinning oven until the fall of glass drops formed by the heating of the glass rod and a detector below the shutter for detecting the fall of the glass drops, for the purpose of automatically opening the shutter when a preset time of the timer is over and automatically closing the shutter by detection by the detector, thereby dispensing with a worker's monitoring of the spinning oven for opening and closing the shutter and preventing a danger of giving damage to the shutter and the spinning oven in the event of delayed shutter opening-closing timing.
