Claim 14:
15. A method of assembling a paperboard spool from a one-piece paperboard blank, the method comprising:
connecting a first arbor panel of a plurality of arbor panels to a second arbor panel of the plurality of arbor panels, wherein the first and second arbor panels form at least a portion of an arbor that extends about an arbor axis;
forming a first flange panel crease line between the first arbor panel and a first flange panel of a first plurality of flange panels such that the first flange panel is rotatable relative to the first arbor panel; and
forming a second flange panel crease line between the second arbor panel and a second flange panel of the first plurality of flange panels such that the second flange panel is rotatable relative to the second arbor panel,
wherein the first plurality of flange panels compose a first flange that is configured to transition between a retention configuration and an open configuration, wherein in the retention configuration, the first and second flange panels of the first plurality of flange panels extend from the respective first and second arbor edges to a retention height, and wherein in the open configuration, the first and second flange panels of the first plurality of flange panels extend from the respective first and second arbor edges to an open height, the retention height and the open height extending in a flange direction from the arbor axis, the flange direction being substantially perpendicular to the arbor axis, and
wherein the retention height is greater than the open height, wherein in the retention configuration, the roll of material is substantially prevented from removal from the arbor along the arbor axis by the first flange and a second flange, the first flange being spaced from the second flange along an arbor direction that is substantially parallel to the arbor axis, and wherein in the open configuration, the roll of material is removable from the arbor along the arbor axis in the arbor direction.
