Abstract: A method and apparatus for automatic threading and winding of optical fiber onto various components in a fiber draw system, as well as methods and apparatus for conducting online tensile screening of optical fiber at high speeds. In a preferred embodiment, the fiber is tensile tested during fiber draw and wound directly onto a shipping spool to be shipped to a customer. The tensile stress can be imparted to the fiber during the draw process by feeding the fiber through a screener capstan, which works in conjunction with another capstan to impart the desired tensile stress to the fiber during the draw process. Another aspect is a method and apparatus for threading or rethreading of a moving length of fiber through a fiber draw or fiber testing process, in which fiber is wound onto a spool, comprising activating an aspirator to obtain the fiber at a first location and moving said aspirator in at least two dimensions to thereby move the fiber to a second location and thread the fiber through or onto at least one component in the fiber draw or testing process.

Abstract: An apparatus for threading a fiber that is being continuously supplied by a supplying device (11) for winding on a spool, includes a collecting device (80), adjacent to the supplying device, that collects the fiber by urging the fiber from the supplying device (11) into the collecting device (80) to provide a tension (20) in the fiber between the supplying device and the collecting device, a positioning device (90) that engages the fiber, between the supplying device (11) and the collecting device (80), with an engaging portion that allows the fiber to be continuously collected in the collecting device (80) and that moves from a position adjacent to the supplying device (11) and the collecting device (80) to a position adjacent to the spool (70,70') to move the fiber to at least one threading position, and a threading device that automatically threads the fiber at the at least one threading position onto the spool.

Abstract: An apparatus and method for reducing or preventing fiber entry whip as the loose end of a fiber being wound on a spool enters a fiber winding device. A fiber winding device includes a spool winder entrance, a winding spool and a fiber whip shield substantially surrounding the winding spool. A fiber entry whip reducer positioned in front of the fiber winding device includes at least one pulley and a guide channel including a straight entry section and a curved section leading to the fiber winding device. The guide channel is formed and positioned such that the loose end of the fiber is maintained against the guide channel by centrifugal force imparted onto the fiber by the curvature of the channel and forward motion of the fiber produced by the rotating spool, thereby producing a trajectory such that the loose end of the fiber enters the fiber winding device and is maintained against the whip shield. By maintaining the free end of the fiber against the guide channel during fiber entry, whip damage to the fiber on the spool due to impact of the fiber end during its entry is substantially reduced or completely eliminated.
