  • Spiral for traversing strand material
    Patent number: 4025002
    Abstract: A novel spiral for the traversing of strand material, andespecially glass strands, during winding of the strands onto a mandrel is disclosed. The spiral includes a third wing which, when the direction of travel of the spiral is reversed, permits strand to be wound on an edge of the mandrel during a call down and before the winder is stopped. Alternatively, the novel spiral may be employed to form a tie-on-tail of strand during winding of a forming package.
