Abstract
Abstract In a package having a wound body of strand having an outer cylindrical portion and an elastic membrane convolutely wound about the cylindrical portion in a plurality of plies, the membrane being of a sufficient thickness and being stretched sufficiently to partially collapse as the strand is withdrawn from the interior of the body, such that the membrane mechanically captures the strand of the outer cylindrical portion to retain such strand along said membrane until said strand is withdrawn from the package wherein the improvement comprises: a control layer of material having different physical characteristics than said membrane, said control layer being positioned between the plies of said membrane to control the collapse of said membrane to a predetermined amount.

Claim 1
Independent Claim
116 words
In a package having a wound body of strand having an outer cylindrical portion and an elastic membrane convolutely wound about the cylindrical portion in a plurality of plies, the membrane being of a sufficient thickness and being stretched sufficiently to partially collapse as the strand is withdrawn from the interior of the body, such that the membrane mechanically captures the strand of the outer cylindrical portion to retain such strand along said membrane until said strand is withdrawn from the package wherein the improvement comprises: a control layer of material having different physical characteristics than said membrane positioned between the plies of said membrane to control the collapse of said membrane to a predetermined amount.
Claim 2
Dependent Claim
116 words
In a package having a wound body of strand having an outer cylindrical portion and an elastic membrane convolutely wound about the cylindrical portion in a plurality of plies, the membrane being of a sufficient thickness and being stretched sufficiently to partially collapse as the strand is withdrawn from the interior of the body, such that the membrane mechanically captures the strand of the outer cylindrical portion to retain such strand along said membrane until said strand is withdrawn from the package wherein the improvement comprises: a control layer of material having different physical characteristics than said membrane positioned between the plies of said membrane to control the collapse of said membrane to a predetermined amount.
Claim 3
Dependent Claim
21 words
The package of claim 1 wherein said control layer is selected from the group consisting of paper, polymer, and fibrous glass.
Claim 4
Dependent Claim
28 words
The package of claims 1 or 2 wherein the membrane is present in about 1 to about 2 wraps between said body of strand and said control layer.
Claim 5
Dependent Claim
22 words
The package of claim 3 wherein said control layer encircles from about 3/4 to about 2 times the circumference of the body.
Claim 6
Dependent Claim
21 words
The package of claim 4 wherein said membrane is wrapped from about 1/4 to about 2 times beyond said control layer.
Claim 7
Dependent Claim
120 words
In the method of forming a package having a wound body of strand having an outer cylindrical portion and an elastic membrane convolutely wound about the cylindrical portion in a plurality of plies, the membrane being of a sufficient thickness and being stretched sufficiently to partially collapse as the strand is withdrawn from the interior of the body such that the membrane mechanically captures the strand of the outer cylindrical portion to retain such strand along said membrane until said strand is withdrawn from the package wherein the improvement comprises: providing a control layer of material having different physical characteristics than said membrane between the plies of said membrane to control the collapse of said membrane to a predetermined amount.
