Abstract
A leading end of packaging material is grasped in a packaging material holder while a load is wrapped. Packaging material is dispensed from a packaging material dispenser, and relative rotation is provided between the dispenser and a load to wrap packaging material around the load. The packaging material holder is positioned on the rotating surface of a turntable but is isolated from any electrical or fluid power source of a rotatable surface of the turntable. During the wrapping cycle, a spring builds and stores energy as the packaging material holder moves downstream along the turntable, automatically releasing the leading end of the packaging material and automatically grasping a trailing end of the packaging material. At least a portion of the packaging material is cut between the packaging material holder and the load, and the spring releases the stored energy to move the packaging material holder upstream toward the dispenser.
