Method and apparatus for producing glass ribbon

A glass manufacturing apparatus includes a forming apparatus defining a travel path extending in a travel direction. The forming apparatus conveys a glass forming material strip along the travel path in the travel direction of the forming apparatus. The glass manufacturing apparatus includes a cooling tube extending substantially parallel to the path of travel and extending across the direction of travel. The cooling tube includes a plurality of apertures spaced along the cooling tube and facing the travel path. A method of making glass may include flowing coolant from an outlet of a conduit in a direction toward a target location of a flowing ribbon of molten material. The method may also include changing a phase of the coolant while the coolant flows toward the target location. The phase change may cool the target location. 一种玻璃制造设备包括成型设备，所述成型设备限定在行进方向上延伸的行进路径。所述成型设备沿着在所述成型设备的所述行进方向上的所述行进路径输送玻璃成型材料带。所述玻璃制造设备包括冷却管，所述冷却管基本上平行于所述行进路径延伸并且跨所述行进方向延伸。所述冷却管包括多个孔口，所述多个孔口沿着所述冷却管间隔开并且面向所述行进路径。制造玻璃的方法可包括：使冷却剂在朝向流动的熔融材料
