Abstract
Abstract A package of flexible material is produced by a winding in the nature of a universal wind on a spindle of oblong shape, or by winding a package on a cylindrical spindle and thereafter compressing the package in a direction transverse to the spindle axis into an oval shape. A radial hole is built into the package, preferably substantially at one of the sides of the oblong, and the flexible material is fed out from the interior of the package through this hole by means of a payout tube inserted in the hole and extending into the central interior of the package where it flares outwardly. The completed package, if wound on a mandrel having flat sides, while the guide and the spindle maintain constant speeds, will be thicker in the elongated sides than in the substantially semi-edge portions because the cross-overs in the end portions are spaced further apart than in the side portions. Thus when one or both of the side walls are flattened, as by insertion in a container, the flattened side wall portions push inwardly so that the interior walls of the axial space are closer together at the center than at the sides. By driving the spindle at a suitable variable speed, the cross-overs can be spaced evenly around the package and the thickening of the longer sides is avoided.
