Abstract
Abstract A package of flexible material formed by a plurality of layers each composed of a series of figure-8''s has a radial opening thereinto through which the inner end of the material is led out of the package. Generally conical members with rounded points extend into the axial space within the package from each end, the tips of the conical members being spaced apart by a distance only slightly greater than the greatest cross-sectional dimension of the flexible material, or being movable apart to provide such a space. The conical members are supported so as to be out of contact with the flexible material. A number of such packages are mounted in a container, the conical members being carried by the walls of the container and the flexible material of the packages being successively connected to each other.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
149 words
A package of flexible material comprising a plurality of layers each formed of a plurality of figure-8 winds with the cross-overs of the winds progressing around the package, said package having a radial opening therein midway of its length, and having an axial opening into which such radial opening extends, and the free inner end of the material being led out through said radial opening, said package including a pair of inwardly tapering members extending into said axial opening from each end terminating adjacent the hole, the points of said tapering members being cut away, the distance between the apices of each of the tapering members and the base thereof being substantially at least as great as the distance between the base and the transverse midplane of the package, whereby to guide loops of material withdrawn from the package to said transverse midplane for payout through said radial opening.
Claim 2
Dependent Claim
149 words
A package of flexible material comprising a plurality of layers each formed of a plurality of figure-8 winds with the cross-overs of the winds progressing around the package, said package having a radial opening therein midway of its length, and having an axial opening into which such radial opening extends, and the free inner end of the material being led out through said radial opening, said package including a pair of inwardly tapering members extending into said axial opening from each end terminating adjacent the hole, the points of said tapering members being cut away, the distance between the apices of each of the tapering members and the base thereof being substantially at least as great as the distance between the base and the transverse midplane of the package, whereby to guide loops of material withdrawn from the package to said transverse midplane for payout through said radial opening.
Claim 3
Dependent Claim
31 words
In a package as claimed in claim 1, the distance between the ends of the tapering members being not more than five times the greatest cross-sectional dimension of the flexible material.
Claim 4
Dependent Claim
30 words
In combination with a package as claimed in claim 1, an enclosing member having walls opposite each end of the axial opening, the tapering members being carried by said walls.
Claim 5
Dependent Claim
17 words
A package as claimed in claim 1, in which the axes of the tapering members are noncoincident.
Claim 6
Dependent Claim
43 words
A package as claimed in claim 1, in which means are provided mounting at least one of the tapering members for longitudinal adjustment, said members are of electrically conductive material and an electric circuit including an indicating means is connected to said members.
Claim 7
Dependent Claim
23 words
A package as claimed in claim 1, in which the tapering members are conical and have longitudinal grooves in the outer surface thereof.
Claim 8
Dependent Claim
17 words
A package as claimed in claim 1, in which the tapering members have separable normally contacting surfAces.
Claim 9
Dependent Claim
46 words
A package as claimed in claim 1, in which the tapering members are conical, at least one having an open end and a ball in said end normally engaging the tip of the other conical member, and means urging the ball into contact with such tip.
Claim 10
Dependent Claim
35 words
A package as claimed in claim 1, in which the axial opening is of substantially constant diameter and the larger ends of the tapering members are of substantially the same diameter as the axial opening.
Claim 11
Dependent Claim
36 words
A package as claimed in claim 1, in which the ends of the axial opening are of at least as great diameter as the diameter of the axial opening at the transverse midplane of the package.
Claim 12
Dependent Claim
125 words
A package of flexible material comprising a plurality of layers each formed of a plurality of figure-8 winds with the cross-overs of the winds progressing around the package, said package having a radial opening therein midway of its length, and having an axial opening into which such radial opening extends, and the free inner end of the material being led out through said radial opening, said package including a pair of inwardly tapering members extending into said axial opening from each end terminating adjacent the hole, the points of said tapering members being cut away, the distance between the apices of each of the tapering members and the base thereof being greater than the distance between the base and the transverse midplane of the package.
Claim 13
Dependent Claim
125 words
A package of flexible material comprising a plurality of layers each formed of a plurality of figure-8 winds with the cross-overs of the winds progressing around the package, said package having a radial opening therein midway of its length, and having an axial opening into which such radial opening extends, and the free inner end of the material being led out through said radial opening, said package including a pair of inwardly tapering members extending into said axial opening from each end terminating adjacent the hole, the points of said tapering members being cut away, the distance between the apices of each of the tapering members and the base thereof being greater than the distance between the base and the transverse midplane of the package.
Claim 14
Dependent Claim
115 words
In combination with a package of flexible material comprising a plurality of layers each formed of a plurality of figure-8 winds with the cross-overs of the winds progressing around the package, said package having a radial opening therein midway of its length, and having an axial opening into which such radial opening extends, and the free inner end of the material being led out through said radial opening, said package including a pair of inwardly tapering members extending into said axial opening from each end terminating adjacent the hole, the points of said tapering members being cut away, means mounting said tapering members with respect to the package out of contact with the flexible material.
