Abstract
A method and device for handling and deploying a sheet of material are provided. In a first version, a rigid rod is positioned within a flexible cylindrical core and the sheet is wrapped around the core. The rod is then removed from the core and the core and sheet may be folded and reshaped for storage or shipment. The core and sheet may then be unfolded and the sheet may be unwrapped from the core. The rigid rod may be positioned within the core after the core is unfolded and to enable easier removal of the sheet from the core. A dispenser may be provided that attaches to the core and/or the rod and enables an operator to unwrap the sheet from the core. The core may be sufficiently rigid to allow the dispenser to be coupled with the core and without positioning of a rigid rod within the core.
