Definitions
- the twill 322 adjusts the flow rate of the molten glass 12.
- the twill 322 can move up and down with respect to the lip 324 forming the flow path of the molten glass 12 and is inserted into the flow path of the molten glass 12 to adjust the opening degree of the flow path of the molten glass 12.
- the cross-sectional shape of the lower surface of the twill 322 may be a curved shape convex downward.
- support grooves 348a and 350a for supporting the limiting wall 328 may be provided in the left side wall 348 of the spout space S1 and the right side wall 350 of the spout space S1, respectively.
- the support grooves 348 a and 350 a restrict the movement of the limiting wall 328 in the flow direction of the molten glass 12. Therefore, for example, when the limiting wall 328 is split in half at the center in the left-right direction (the center in the vertical direction in FIG. 3), the broken pieces can support each other and can be prevented from falling onto the molten glass 12.
- the first space S11 on the upstream side is filled with nitrogen gas, there is little hydrogen gas around the tween 322 that forms the first space S11 and the channel pipe 334 provided on the upstream side of the twill 322, and platinum or platinum Deterioration of a member formed of an alloy can be suppressed.
