  • Fiber entry whip reduction apparatus and method therefor
    Patent number: 6152399
    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 comprises 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 comprises 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.
