The thickness of the coating film in the roller of the present invention is not particularly limited, and is preferably 〇.05 to 1 mm, more preferably 〇1 to 0.5 mm. The reason for this is that if the thickness is too small, the properties of the coating film cannot be sufficiently exhibited, and if the thickness is too thick, the adhesion properties are lowered. Further, the thickness of the coating film is a value calculated by using a micrometer or a vernier caliper to measure the thickness of the substrate before the spraying and the thickness after spraying and polishing, and thereby calculating the difference based on the difference. Further, the coating film in the roller of the present invention can be formed by the method described later, but it is preferably formed on the surface of the roller main body portion by the HVOF spraying method (high-speed flame coating method). More preferably, the coating film is formed by containing 2 to 30% or 4 to 90% of the above-mentioned ceramic particles in the c-heart alloy, and is formed by the HVOF nozzle coating method. Further, it is more preferable that the coating film is a coating film described above and is formed by a HVOF spraying method. The roller of the present invention has such a coating film on at least the portion of the surface of the roller main body which is in contact with the glass. Preferably, the roller of the present invention has the above-mentioned coating film on all portions of the surface of the roller main body which are in contact with the flat glass. In the case where the roller of the present invention has a convex edge in the main body of the roller as described below, since the convex edge is in contact with the flat glass, it is preferable to have a coating on the surface of the convex edge 135920.doc -12· 200932689 Membrane. The part other than the above-mentioned coating film in the roller of the present invention is not particularly limited as long as the above-mentioned coating film of the present invention is not limited, and for example, it may be a rabbit The float plate glass transfer roller is the same. /J,, it. Buy, shape, etc. are not particularly limited, and may be the same as the previous ones such as stainless steel. In the case of a cylindrical body including an alloy steel such as stainless steel, that is, a roller φ main body, a shaft is attached thereto, but it is preferable that the surface of the roller body of the cylindrical body has a convex surface. The reason for this is that by reducing the contact point, it is possible to obtain a source of the reduction/s scar, and to reduce the stress relaxation caused by the heat absorption from the glass. The roller of the present invention of the preferred embodiment will be described with reference to the drawings. Fig. 1 is a schematic side view of a floating flat glass conveying roller having a convex surface on the surface of the main body of the tweezers, and Fig. 2 is a schematic cross-sectional view thereof. In Fig. 1 and Fig. 2, 1 is a roller main body portion of a metal base material, and a flange of a surface of a 12-system φ roller main body portion 11 is attached to the surface of the convex edge 12 in contact with the floating flat glass. The above-mentioned coating film formed in part is 15 attached to the shaft of the roller main body portion 11. • The length of each part or the number of flanges is not particularly limited. For example, the length L1 of the longitudinal direction (axial direction) of the roller main body portion 11 can be set to 4 〇〇〇 to 6 〇〇〇 mm, and the diameter of the cross section perpendicular to the longitudinal direction can be set to 200 to 400 mm. The height L3 of the convex edge 12 from the surface of the roller main body portion can be set to 4 to 10 mm, and the width L4 of the convex edge 12 in the parallel direction with respect to the longitudinal direction of the roller main body portion u can be set to 20 to 60. Mm, the edge of the edge 12 between 135920.doc 13 200932689 The distance from L5 can be set to 100~3〇〇mm. = where, (four) is good 5~7 position. " It is better that the %(9) axis is better 150 ~250 mm. Because of the 5 ^ ^ ± 〆, the reason is that even if the flat glass that is conveyed is thin, the deflection of the flat glass plate between the convex edges is smaller, so that it is in contact with the convex edge. Further, scratches are formed on the flat glass. Further, in Figs. 1 and 2, the shaft 15 is mounted on the shaft, and the roller body (four) may be formed as follows: the sub-body portion 丨/, the glaze is integrated and cast Alternatively, the flange may be integrated with the main body of the roller, etc. Next, a method of manufacturing the roller of the present invention will be described. The method of manufacturing the roller is not particularly limited. For example, if the cylindrical body obtained by casting the machine and the W is used as the 2 convex, the convex edge is welded to the surface thereof, and the welding is performed by the HVQF. After spraying, electric blasting, coating, line blasting, etc., the coating method is formed on the surface at least in contact with the glass, and then adjusted by mechanical grinding or the like as needed. The length of the surface of the film is mounted inside. The opening at the end of the length direction inserts the shaft into the shape of the body. As long as the body portion is a cylindrical body, other methods may be used, and the material of the convex edge may be combined with the body. The part and the material manufacturing method and material are not particularly limited. It may be a previously known material formed by a conventionally known method. Thus, the roller of the present invention can be manufactured. a method for producing a floating flat glass using a roller-surface transfer and surface-cooling step of the present invention as described in 135920.doc • 14-200932689, for transporting the following floating flat glass, Very few scratches are available The floating flat glass is preferred. Here, the floating flat glass is more preferably 5 〇〇 1 or less and further preferably 43 (TC or less. The reason is that a flat glass having less scratches can be obtained. Although the roller of the present invention can be used for transportation at a normal temperature, it is preferably used for the conveyance of a floating flat glass of i5〇t or more which is difficult to use the resin roller. ❹ 、 In the method for producing a flat glass, the same method as the conventional floating flat glass is used except that the roller of the present invention is used for conveying a floating flat glass of 6 inches or less. For example, the following manufacturing method is used: After the glass raw material is supplied to (4) g which is set to about 1600 C to obtain (4) glass, the molten glass is poured into a tin bath filled with molten tin to form a flat glass, and the roller of the present invention is transported from the tin bath while being discharged. And the flat glass supplied to the slow cooling furnace = slow cooling on one side. The temperature of the flat glass near the population of the slow cooling furnace is usually about 7 °C. It is also possible to use the roller sheet glass of the present invention only in the region where the temperature of the flat glass is below. As the roller of the present invention, it is preferable to use the above-mentioned flange. 2. A floating flat glass using the roller of the present invention as described above: the type, size, thickness and the like of the flat glass of the manufacturing method are also not particularly limited, and can be preferably applied to a thickness of 0.3 to 3 mm. The good one is 〇.3~〇8 mm, and the better one is the glass plate for liquid crystal display. By using (4) the roller of the present invention and performing slow cooling, scratching of the glass can be suppressed. This effect is more pronounced if the roller system of the present invention has the aforementioned rims. [Examples] Hereinafter, the present invention will be described in more detail with reference to examples but the present invention is not limited thereto.

[Industrial Applicability] The floating flat glass conveying roller of the present invention is difficult to cause burrs or scratches on the surface of the roller main body due to the glass genus of the flat glass which is broken in the slow cooling, and the glass swarf It is difficult to scratch the surface of the main body of the roller, so that the floating flat glass can be prevented from being scratched by the roller. In particular, in the case of a glass substrate for a display, the yield is greatly reduced with the occurrence of scratches.
