METHOD AND APPARATUS FOR MANUFACTURING A GLASS RIBBON

A glass manufacturing apparatus includes a conduit in fluid communication with a delivery chamber and an inlet of a forming device. The conduit includes a closed sidewall surrounding a channel extending in a flow direction of the conduit. A glass manufacturing apparatus includes a housing surrounding a conduit and extending along a length of the conduit. The housing includes a refractory material in contact with the conduit such that an inner surface of the housing substantially matches a shape of an outer surface of the sidewall. Methods of making a glass ribbon are provided. 一种玻璃制造设备包括与输送室和成形装置的入口流体连通的导管。导管包括围绕在导管的流动方向上延伸的通道的封闭的侧壁。玻璃制造设备包括围绕导管并沿导管的长度延伸的外壳。外壳包括与导管接触的耐火材料，使得外壳的内表面与侧壁的外表面的形状基本上匹配。提供了制造玻璃带的方法。
