Abstract
A roll product is wrapped with a sheet of stretch wrap packaging material dispensed from a stretch wrap dispenser. A portion of the sheet is positioned between a clamp and the stretch wrap dispenser so that the portion of the sheet is across a load path between the load and a roller for rotating the load. The load is transported along the load path and placed in driving contact with the roller. The load is rotated by driving the load with a roller. The clamp is moved from a first location to a second location where the sheet is wrapped around the load and secured in place by another portion of the sheet.
