1. the method for manufacture of a glass stick;

  • The top of larger-diameter glass preform via stove supplied in the said stove;

    And draw said glass preform from said stove via the bottom of said stove;

    Make said larger-diameter glass preform drawn glass stick, said method comprising the steps of than small dia;

    Control the feed speed and the drawing speed of said glass preform, make that the ratio between said feed speed and the said drawing speed becomes the determined value of aimed dia based on the diameter and the said glass stick of said glass preform;

    Obtain the diameter of the said glass preform that is used for confirming said ratio by measured diameter data, wherein obtain said measured diameter data through the diameter that draws preceding said glass preform along length direction measurements of said glass preform;

    AndConfirm said feed speed with said feed speed according to the mode that the fluctuation of the said measured diameter data on the said length direction changes.
