Abstract
A package for a wind of flexible material wound with a universal wind and having a radial opening into the axial opening through which the inner end of the material is brought out is provided with specially shaped cones having end portions extending into the inner end of the radial opening to guide the material to prevent tangles and birdnesting during unwinding of the wound material. The end portions of the specially shaped cone members may be inserted into the end portion of the payout tube which, in turn, is inserted within the radial opening of the wound package.
