    • This invention involves apparatus and methods for making fibers by passing a molten material like glass, polymer, etc. through orifices or tips in a fiberizing bushing (2) and then cooling the molten material coming from the tips (12) and newly formed fibers using cooling tubes (16). The cooling tubes (16) are made from precious metals and various alloys comprising precious metals, nickel and one or more of titanium, chromium, molybdenum, etc. The one or more fins (18) attached to the top surface of a hollow tube to make the cooling tubes (16) contain spaced apart gaps (29), notches and/or slots extending from the top edge of the fin (18) to prevent warping of the fins and to make the cooling tube more bendable, adjustable during the operation of making fibers from molten material.
    • 本发明涉及通过使诸如玻璃,聚合物等熔融材料通过孔或尖端在纤维化套管(2)中进行纤维来制造纤维的装置和方法,然后使用尖端(12)和新形成的纤维冷却来自熔融材料的新型纤维 冷却管(16)。 冷却管(16)由贵金属和包含贵金属,镍和钛,铬,钼等中的一种或多种的各种合金制成。一个或多个翅片(18)附接到中空管的顶表面 使得冷却管(16)包含间隔开的间隙(29),从翅片(18)的顶部边缘延伸的凹口和/或狭槽,以防止翅片翘曲并且使得冷却管更可弯曲,在操作期间可调节 从熔融材料制造纤维。
