  • Method and apparatus for reducing catenary during winding of a fiber bundle
    Patent number: 5957402
    Abstract: The present invention relates to a method and apparatus for reducing catenary during winding of a fiber bundle which includes a plurality of fiber strands into a wound package. The method includes: applying substantially equal tension to each of a plurality of fiber strands; gathering the strands to form a bundle; advancing the bundle at a predetermined speed and tension toward a winding device; measuring the tension of the bundle; adjusting the tension of the bundle by adjusting the speed at which the bundle is advanced, such that (1) the speed of advancement of the bundle is increased when the measured tension of the bundle exceeds a predetermined value and (2) the speed of advancement of the bundle is decreased when the measured tension of the bundle is less than a second predetermined value; and winding the bundle to form a wound package.
