Abstract
The invention relates to a package of material wound in a series of figure-8s with the cross-overs advancing around the package, and the cross-overs being omitted at at least one point on the circumference of the package to leave a radial hole into the center of the package for inner end feedout to allow payout without twist. This hole is ordinarily somewhat diamond shaped, with its major axis extending substantially perpendicular to the axis about which the material was wound. A payout tube is placed in that hole, this payout tube having an oval shape.
