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.
Claims2
A package comprising a coil of flexible material wound in a plurality of layers of Figure-8 winds with the cross-overs progressing around the package in each layer and having a radial opening through the wall of the coil from the outside to a central core space of the wound flexible material, said radial opening having a greater length in the direction substantially perpendicular to the axis about which said material was wound, and a payout tube passing through said radial opening through which the inner end of the material is drawn out, said payout tube being oval in cross-section with its major axis extending parallelly to said perpendicular direction, the cross-section of the material being less than the minor axis of said payout tube.
