Abstract
Abstract In a package formed of a plurality of layers each composed of a number of figure 8 winds with the cross-overs progressing around the package and with a radial opening extending from the periphery of the package to the axial opening through which radial opening the inner end of the material is led out, a funnel is provided with a stem positioned in the radial opening and with its mouth substantially at the mid-plane of the package. The funnel has a width in the axial direction of the package at least substantially as great as the axial length of the package. The funnel may be mounted in such a way that it can wobble slightly. The funnel guides the loops falling off of the inside wall of the package so as to prevent birdsnesting and provide for continuous and rapid payout.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
A package of flexible material constituted by a plurality of layers each formed of a plurality of figure 8s wound about a common axis with the cross-overs of each layer progressing around the package and having an axial opening therein and a radial opening extending from the periphery of the package to the axial opening, through which radial opening the inner end of the material is led out, a funnel mounted within the axial opening with its axis directed radially of the package and aligned with said radial opening, the mouth of the funnel having a dimension in the axial direction of the package at least substantially as great as the axial dimension of the package.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
20 words
A package as claimed in claim 1, in which the funnel includes a hollow stem extending through the radial opening.
Claim 4
Dependent Claim
18 words

Claim 5
Dependent Claim
37 words
In a package as claimed in claim 1 in which the axial dimension of the package is substantially greater than the diameter of the axial opening and the mouth of the funnel is substantially elliptical in shape.
Claim 6
Dependent Claim
22 words
In a package as claimed in claim 1, in which the mouth of the funnel extends beyond the ends of the package.
Claim 7
Dependent Claim
25 words
