Collapsible and expandable roll riser

A roll riser for use such as in staggering paper rolls during shipment generally includes first and second deck sheets each having inner and outer sides, a fold line along the edge of the core and a fold line along its midpoint, and are connected together by an open-celled core. The roll riser is collapsible along the fold lines for shipment to the user or for storage so as to occupy a relatively small amount of space and then expanded by the user for use. In a first embodiment, pressure sensitive tape is secured to the inner sides of the sheets and when the roll riser is in an expanded configuration, the tape adheres to the core. In a second embodiment, pressure sensitive tape is secured to the outer side of the first sheet and when the roll riser is in an expanded configuration, the tape is adhered to the outer sides of the first and second sheets. In each embodiment, the tape causes the roll riser to remain in the expanded configuration so as to prevent the roll riser from collapsing.
