ABSTRACT:
The instant invention comprises an apparatus and method for wrapping a load under tension with a web of stretch wrap flexible material and then binding the wrapping material to the load by compressing the end of the flexible material into a rope-like configuration. The rope formed is wound around the load at least one turn. A second turn of the rope around the load is then bound to the first rope with a mechanical twisting tie around the two ropes to prevent unwrapping of the load during transit and storage. A hot wire cutting mechanism cuts the rope and the bound two ropes snap back into position against the wrapped load from the force of the stretch wrap tension.
