Abstract
A technique for dynamically transferring a lightguide fiber (10) from a full spool (18) to an empty spool (19) as both spools rotate at the same velocity and the input velocity of the fiber is constant. The lightguide fiber (10) is wound onto the rotating spool (18) in such a manner as to form a package of wound material having a conically tapered section (52) when full. The fiber (10) is then wound along the tapered section (52) as the velocity of the spools (18 and 19) are increased. When the fiber (10) is at the diameter of the tapered section (52) which is equal to the diameter of the empty spool, it is transferred to the empty spool without any substantial loss of fiber spooling control.
