Abstract

Methods and apparatus for dispensing a predetermined fixed amount of pre-stretched packaging material to a load are disclosed. An amount of pre-stretched packaging material to be dispensed by a packaging material dispenser is determined based upon the girth of the load to be wrapped. Once the amount of packaging material to be dispensed is determined, a ratio of relative rotational speed to packaging material dispenser speed can be set and mechanically controlled. In an alternative embodiment, the ratio is electronically controlled.
