METHOD AND APPARATUS FOR MANUFACTURING A GLASS RIBBON

A glass manufacturing apparatus includes a forming apparatus for defining a travel path extending along a travel direction. The forming apparatus conveys a ribbon of a glass forming material along a travel path in a travel direction. A glass manufacturing apparatus includes a cooling tube having a first end and a second end. The cooling tube includes a first tube including a first closed sidewall surrounding a first passage. The first tube receives a first cooling fluid within the first channel. The cooling tube includes a second tube including a second closed sidewall surrounding a second passage. The first tube is positioned within the second tube. The second tube receives a second cooling fluid within the second channel. The cooling pipe comprises a nozzle. The nozzle receives the first cooling fluid and directs the first cooling fluid toward the travel path. The method includes manufacturing a glass ribbon with a glass manufacturing apparatus. 玻璃制造设备包括用于定义沿着行进方向延伸的行进路径的形成设备。形成设备在行进方向上沿着行进路径传送玻璃形成材料的带状物。玻璃
