  • Automated method and system for making capillary splice
    Publication number: 20050229640
    Abstract: A method of making a capillary splice includes applying pressure to a bore in a tube, applying heat to a portion of the tube to soften the portion of the tube, and forming a bubble within the bore in the heated portion under the influence of the pressure and heat. While forming the bubble, a diameter of the bore at the heated portion is measured to determine when the bubble has enlarged to a target size. When the bubble has enlarged to the target size, a force is applied along an axial axis of the tube to shape the bubble to a desired size.
    Type: Application
