| titleOfInvention | Glass rod drawing method and glass rod drawing apparatus |
| abstract | An object of the present invention is to provide a glass rod stretching method capable of shortening the length of an upper support rod attached to the upper end of a glass rod and blocking the inside of a heating furnace from outside air. An upper support bar 31 and a lower support bar 32 each having a smaller outer diameter are attached to both ends of a glass rod 30, and the glass rod 30 to which these support bars are attached is inserted into a heating furnace 13. The glass rod 30 is softened by heat treatment, and the glass rod 30 is stretched to have a predetermined outer diameter. When the upper end surface 30a of the glass rod 30 is outside the heating furnace 13, the first sealing body 16 is disposed on the upper end surface 13 a of the heating furnace 13, the upper opening 17 of the heating furnace 13 is covered with the first sealing body 16, and when the upper end surface 30 a of the glass rod 30 is in the heating furnace 13, the second The sealing body 18 is overlaid on the first sealing body 16, the upper opening 17 of the heating furnace 13 is covered with the second sealing body 18, and the inside of the heating furnace 13 is shut off from the outside air.
