- the melting temperature of tin is about 230 ° C.
- the melting temperature range of tin is typically in the range of 230 ° C to 230 + 10 ° C. Therefore, the position where the removal member contacts the glass ribbon is in a temperature range higher than the melting point of the tin. In this temperature range, the main foreign substance, tin, is in a liquid temperature range, so that the foreign substance can be easily wiped off by the removal member.
- High melting point foreign substances such as tin oxide are usually carried on molten tin and can be easily wiped off with molten tin.

Therefore, the removal member is brought into contact with the surface of the glass ribbon in the lift-out area or upstream of the layer area, and in particular, the glass ribbon in the lift-out area. It is preferable to contact the surface.
- the contact position of the removal member is in the melting temperature range of tin, if there is a large amount of high melting point foreign matter (particularly tin oxide), it may be difficult to wipe off sufficient foreign matter. Since molten tin is easily oxidized, it is not preferable that the molten tin, which is a foreign material, oxidize before the contact of the removal member. Therefore, it is preferable that at least the contact position of the removal member and the atmosphere upstream thereof where the glass ribbon exists are in a reducing gas atmosphere or an inert gas atmosphere (the two atmospheres are also referred to as non-oxidizing atmospheres). The liftout area is usually maintained in the same reducing gas atmosphere as the float bath.
- the portion where the gas in the liftout area upstream of the layer area flows is usually in a reducing gas atmosphere or an inert gas atmosphere. Therefore, as long as the contact position of the removal member is in these regions, it is considered that oxidation of the molten tin is difficult to proceed. Also, particularly in the upstream of the layer area, there is a possibility that an oxidizing atmosphere may be temporarily formed. Therefore, the glass ribbon is present, the abutting position of the removing member and the reducing gas is supplied to the upstream, and so on. Can be kept in a non-oxidizing atmosphere.

- the removal member is made of a material that is easily oxidized, such as carbon fiber, it is not preferable that the removal member is in an oxidizing atmosphere.
- the pressurized gas is composed of a non-oxidizing gas.
- the oxygen concentration may temporarily increase. Therefore, reducing gas as a pressurized gas is used to prevent the life of the removal member from being shortened. And are preferred.
- the supply pressure of these gases is preferably set in consideration of pressure loss. If the gas pressure is too low, the contact pressure of the removal member to the glass ribbon surface is lowered, and the removal effect of foreign matter may be reduced. On the other hand, if it is too high, there is a risk that the foreign matter adhering to the removal member will reattach to the glass ribbon surface.
- a force S that can vary depending on the structure of the removing device, or the like, is usually 10 to 100 liters / minute per lm in the width direction.
- supplying this amount of gas means that the removal member is a fixing member. There is also an effect of cooling.
- the oxygen concentration in the non-oxidizing gas or non-oxidizing atmosphere is preferably 1% or less, particularly preferably lOOOppm or less.
- the reducing gas hydrogen, acetylene, or an inert gas containing these is preferable.

The removing member was brought into contact with 20 cm (the length in the width direction of the glass ribbon) at one end of the lower surface of the glass ribbon for 20 days during the manufacturing period of the glass sheet. During that period, the surface of the glass ribbon that passed over the removal member was visually inspected at a frequency of once every 2 hours (total number of inspections: 240) under a high-intensity light source used for normal quality inspection.
