  • Patent number: 4887423
    Abstract: In the processing of light waveguides, a method uses an overhead haul-off from a first supply reel to apply a pre-twist to the light waveguide, which is preserved during a tinting operation and while the tinted waveguide is wound in a tangential direction on a second supply reel. During further processing, in acordance with the present method, the waveguide is taken off by an overhead haul-off process from the second supply reel in a direction of haul-off which is opposite to the direction during the first overhead haul-off so that the twist produced by the second overhead haul-off is in an opposite direction and compensates for the twist produced during the first overhead haul-off operation.
