Method and apparatus for forming hollow fibers |
摘要 |
The instant invention relates to a method and apparatus for the production of hollow glass fibers using a novel tip design. It is believed that the success of the instant invention is due to the injection of pressurized gas to create a central lumen at distances farther removed from the terminus of the tip than taught possible by the prior art. This results in a more stable process and the production of hollow fibers having more uniform wall concentricity.
