Method for securing a load to a pallet with a roped film web
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.
1. A method of wrapping a load, comprising:
dispensing a film web from a film dispenser;
providing relative rotation between the load and the film dispenser to wrap the film web around the load;
engaging the film web with a roller, and maintaining engagement of at least a portion of the film web with the roller throughout wrapping of the load;
selectively driving down the engaged portion of the film web with the roller;
roping an edge portion of the film web to form a rope of film; and
releasing the roller from driving down the engaged portion of the film web by relative rotation between the load and the film dispenser.
2. A method of wrapping a load, comprising:
dispensing a film web from a film dispenser;
providing relative rotation between the load and the film dispenser to wrap the film web around the load;
continuously engaging the film web with a roller while the film is being dispensed, and moving the roller between:
a first position, wherein the film web leaves the roller at a first elevation substantially equal to an elevation at which the film web was received by the roller, and
a second position, wherein the film web leaves the roller at a second elevation different from the first elevation; and
roping a portion of the film web into a rope of film;
wherein moving the roller from the second position to the first position includes releasing the roller with a release device by relative rotation between the load and the film dispenser.
3. A method of wrapping a load, comprising:
dispensing a film web from a film dispenser;
providing relative rotation between the load and the film dispenser to wrap the film web around the load;
while dispensing the film web, continuously engaging the film web with a roller, and moving the roller between:
a first position, wherein the longitudinal axis of the roller is substantially perpendicular to a direction of travel of the film web about the roller, and
a second position angled relative to the first position, to drive down the film web; and
roping a portion of the film web into a rope of film; and
releasing the roller from second position by relative rotation between the load and the film dispenser.
