ABSTRACT:
A roll riser for use, such as in staggering paper rolls, during shipment generally includes a rigid sheet and a core attached by its ends to the sheet along the length of the sheet. The core is collapsible and expandable so as to transform the roll riser from a collapsed configuration to an expanded configuration. First and second end portions of the sheet are folded against a side of the core around fold lines, and lie generally adjacent to the core to cause the roll riser to remain in an expanded configuration.
