Abstract
Abstract A package and a method to produce said package are provided comprising a wound body of strand having an outer cylindrical portion; and an elastic membrane wound about the cylindrical portion of said body, the membrane being wound to a sufficient thickness and being stretched sufficiently to partially collapse when the strand is withdrawn from the body such that the membrane captures the strand of the outer cylindrical portion to retain such strand along said membrane until said strand is withdrawn from the package at a predetermined time.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A package comprising: a wound body of strand having an outer cylindrical portion; and an elastic membrane convolutely wound about the cylindrical portion of said body from about 2 to about 4 times, the membrane being of a sufficient thickness and being stretched sufficiently to partially collapse as the strand is withdrawn from the interior of the body such that the membrane mechanically captures the strand of the outer cylindrical portion to retain such strand along said membrane until said strand is withdrawn from the package at a predetermined time.
Claim 2
Dependent Claim
90 words
A package comprising: a wound body of strand having an outer cylindrical portion; and an elastic membrane convolutely wound about the cylindrical portion of said body from about 2 to about 4 times, the membrane being of a sufficient thickness and being stretched sufficiently to partially collapse as the strand is withdrawn from the interior of the body such that the membrane mechanically captures the strand of the outer cylindrical portion to retain such strand along said membrane until said strand is withdrawn from the package at a predetermined time.
Claim 3
Dependent Claim
155 words
A package comprising: a wound body of strand having an outer cylindrical portion; and an elastic membrane convolutely wrapped about said body from about 2 to about 4 times and having a length at least substantially equal to the height of said outer cylindrical portion wound about the cylindrical portion of said body positioned such that a single layer of said membrane substantially covers all of said cylindrical portion, the membrane being of a sufficient thickness and being stretched sufficiently around said cylindrical portion to partially collapse while retaining a generally cylindrical shape as the strand is withdrawn from the interior of the body such that the membrane mechanically crimps the strand of the outer cylindrical portion between the folds of the membrane as it collapses to retain such strand along said membrane until said strand is withdrawn from the package at a predetermined time to facilitate complete withdrawl of said strand from said package.
Claim 4
Dependent Claim
155 words
A package comprising: a wound body of strand having an outer cylindrical portion; and an elastic membrane convolutely wrapped about said body from about 2 to about 4 times and having a length at least substantially equal to the height of said outer cylindrical portion wound about the cylindrical portion of said body positioned such that a single layer of said membrane substantially covers all of said cylindrical portion, the membrane being of a sufficient thickness and being stretched sufficiently around said cylindrical portion to partially collapse while retaining a generally cylindrical shape as the strand is withdrawn from the interior of the body such that the membrane mechanically crimps the strand of the outer cylindrical portion between the folds of the membrane as it collapses to retain such strand along said membrane until said strand is withdrawn from the package at a predetermined time to facilitate complete withdrawl of said strand from said package.
Claim 5
Dependent Claim
20 words
The package of claim 1 wherein said membrane is statically charged such that the strand is attracted to said membrane.
Claim 6
Dependent Claim
37 words
The package of claims 1 or 2 wherein said membrane collapses along the length of the cylindrical portion within a range from about 10% to about 50% of the package length prior to initiation of strand withdrawal.
