An apparatus and method for wrapping a palletized load are provided. The apparatus preferably includes a film dispenser for dispensing a film web, at least one drive down roller configured to engage the width of the film web, and at least one roping mechanism. The at least one roping mechanism may be a cable rolling element configured to roll a portion of the film web into a rolled cable of film. The apparatus may also include an assembly for providing relative rotation between the load and the dispenser to wrap a roped portion of the film web around a base of the load/top portion of a pallet supporting the load.

Apparatus for securing a load to a pallet with a roped film web

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.

Method for securing a load to a pallet with a roped film web

The present invention provides a method and apparatus for dispensing a predetermined fixed amount of pre-stretched packaging material based upon load girth. A non-rotating ring carries a belt driven by a motor. A packaging material dispenser is mounted on a rotating ring, and the rotating ring may include a pulley that connects to the band, such that the rotating ring is driven by the drive belt. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for each revolution made by the rotating ring is determined. Good wrapping performance in terms of load containment (wrap force) and optimum packaging material use is obtained by dispensing a length of pre-stretched packaging material that is between approximately 90% and approximately 120% of load girth. Once the amount of packaging material to be dispensed per revolution is determined, a ratio of rotating ring drive to final pre-stretch surface speed (i.e., number of pre-stretch roller revolution/rotating ring rotation) can be set and mechanically controlled. Thus, for each revolution of the rotating ring and dispenser, a predetermined fixed amount of packaging material is dispensed and wrapped around the load. In an alternative embodiment, the ratio is electronically controlled.
