Apparatus and methods for compressing at least one roll of compressible material having an outer diameter and a circumference and an inner core having an inner diameter at least one roll of compressible material are provided. For example, a method according to one embodiment includes positioning a chuck about the circumference of the at least one roll, wherein the chuck is configured to engage the at least one roll at a plurality of evenly spaced locations about the circumference of the at least one roll. The method further includes radially compressing the at least one roll at a plurality of evenly spaced locations about the circumference of the at least one roll with the chuck such that the outer diameter of the at least one roll is substantially uniformly reduced without collapsing the inner core.

1. A method for compressing a roll of compressible material having an outer diameter and a circumference and an inner core having an inner diameter, the method comprising: positioning a chuck about the circumference of the roll, wherein the chuck is configured to engage the roll at a plurality of evenly spaced locations about the circumference of the roll; andradially compressing the roll at a plurality of evenly spaced locations about the circumference of the roll with the chuck such that the outer diameter of the roll is substantially uniformly reduced without collapsing the inner core and the roll is independently radially compressed by the chuck. 2. The method of claim 1, further comprising positioning a mandrel within the inner diameter of the inner core prior to compressing the roll. 3. The method of claim 1, further comprising at least partially enclosing the roll with a packaging material either before or after radially compressing the roll. 4. The method of claim 3, wherein enclosing the roll comprises circumferentially wrapping the roll with a packaging material. 5. The method of claim 4, wherein enclosing comprises at least partially enclosing the roll with a heat-shrinkable film and applying heat to the heat-shrinkable film. 6. The method of claim 1, wherein radially compressing the roll comprises radially compressing the outer diameter of the roll with a pair of opposing forces at a plurality of radial locations evenly spaced about the circumference of the roll. 7. The method of claim 1, further comprising providing a plurality of rolls each having an outer diameter and an inner core having an inner diameter and radially compressing the plurality of rolls such that the outer diameter of each of the plurality of rolls is substantially uniformly reduced without collapsing the inner diameter of a respective core; positioning a plurality of chucks about the circumference of each of the respective rolls, wherein each of the chucks are configured to engage each of the respective rolls at a plurality of evenly spaced locations about the circumference of each of the respective rolls; and radially compressing each of the respective rolls at a plurality of evenly spaced locations about the circumference of each of the respective rolls with one of the respective chucks such that the outer diameter of each of the respective rolls are substantially uniformly reduced without collapsing the inner core and each roll is independently radially compressed by a respective chuck. 8. The method of claim 7, further comprising positioning a mandrel within each inner core prior to radially compressing the plurality of rolls. 9. The method of claim 7, further comprising arranging the plurality of rolls in an array of rows either before or after radially compressing the plurality of rolls. 10. The method of claim 1, wherein radially compressing comprises radially compressing the roll to a volume that is at least 25% less than its original volume. 11. The method of claim 1, wherein radially compressing comprises radially compressing the roll in a direction generally perpendicular to a longitudinal axis of the core. 12. An apparatus for compressing roll of compressible material having an outer diameter and a circumference and an inner core having an inner diameter, the apparatus comprising: a chuck configured to engage the roll at a plurality of radial locations evenly spaced about the circumference of the roll and to move and radially compress the roll such that the outer diameter of the at least one roll is substantially uniformly reduced without collapsing the core,wherein the chuck comprises a plurality of fingers configured to engage the roll at a plurality of radial locations evenly spaced about the circumference of the roll and to move and radially compress the roll. 13. The apparatus of claim 12, further comprising at least one mandrel configured to be positioned at least partially within the inner diameter of the inner core and support the inner core while the roll is radially compressed. 14. The apparatus of claim 12, wherein the chuck comprises at least four fingers, wherein a first pair and a second pair of fingers are configured to move and apply opposing radial forces on the roll to radially compress the at least one roll. 15. The apparatus of claim 12, wherein the plurality of fingers are longitudinal and are disposed generally parallel to a longitudinal axis of the core. 16. The apparatus of claim 12, wherein the plurality of fingers are configured to be at least partially embedded within the roll while radially compressing the roll. 17. The apparatus of claim 12, wherein the plurality of fingers are configured to radially compress the roll in a direction generally perpendicular to a longitudinal axis of the core. 18. The apparatus of claim 12, comprising a plurality of chucks, each configured to engage a respective roll, wherein each chuck comprises a plurality of fingers configured to engage and radially compress a single roll such that each roll is independently radially compressed by the plurality of fingers.
