する。(Prior Art) Conventionally, in Danner type glass tube forming, molten glass is supplied from the foreharth of the glass melting furnace to the sleeve through the trough, and the tube is drawn and formed.
A partition plate is provided at the discharge port at the tip of this trough to adjust the flow rate of the glass to be supplied. For example, in FIGS. 3 and 4, a trough 11 connected to a forehearth of a glass melting furnace
There is a discharge channel 12 at the tip of which the molten glass flows out.
A through hole 13 for attaching a partition plate is opened from the top of the trough 11 downward into the molten glass so as to intersect the discharge flow path 12. A partition plate 14 made of refractory material is inserted into this through hole 13,
By raising and lowering the partition plate 14, the opening degree of the discharge channel 12 is changed, and the molten glass to be supplied is adjusted to have a predetermined flow rate. In this glass flow rate adjustment mechanism, the glass flowing into the gap between the partition plate 14 and the through hole 13 is heated from the upper side of the foliage and becomes lower temperature than the glass surface area which is at a high temperature, and this temperature difference causes streaks. occurs and stagnates. This glass sometimes flows out and mixes into the main flow of molten glass, causing streaks several tens of microns wide and several microns high on the glass tube that is fed to the sleeve and drawn.

(Means for Solving the Problem) In order to eliminate the gap between the partition plate mounting through hole and the partition plate, which is the cause of streaks on the glass, the present invention eliminates the gap between the partition plate mounting through hole and the partition plate. The partition plate is simply brought into sliding contact with the opening inside the trough. In other words, there is a glass discharge flow path that opens at the tip of the trough and extends inside the trough, and a partition that is provided in sliding contact with the opening of the discharge flow path inside the trough below the surface of the molten glass and is movable up and down. A molten glass supply trough comprising a plate.

の状態も極めて薄く、問題となることはない。(Function) The trough of the present invention does not have a through hole for attaching the partition plate, and the sliding contact between the partition plate and the opening of the discharge flow path is below the surface of the molten glass, so there is no problem with the gap. First, even if streaks occur due to temperature differences in the glass, they do not stagnate and are extremely small in quantity. Also, since the glass is constantly flowing, the streaks are extremely thin and do not pose a problem.
（実施例）
本考案の詳細を第１図および第２図に示す実施
例により説明する。(Example) The details of the present invention will be explained with reference to an example shown in FIGS. 1 and 2.

うになつている。 A glass discharge channel 2 opened at the tip of the trough 1 extends into the trough 1 along the bottom surface of the trough 1 and opens. A refractory partition plate 4 is disposed in sliding contact with the opening inside the trough 1 of the discharge flow path 2 below the surface of the molten glass 3, and is movable up and down.
The upper part of the partition plate 4 is provided with a well-known support mechanism (not shown).
It is held movably by. This partition plate 4
By raising and lowering the discharge channel 2, the degree of opening of the discharge channel 2 is changed, and the flow rate of the molten glass flowing out is adjusted.
