A method, apparatus and program product utilize a graphical interface to facilitate operator interaction with a load wrapping apparatus, particularly in connection with setting up a wrap profile. The graphical interface may incorporate a graphical depiction of a load, along with graphical depictions of both the number of layers of packaging material and the wrap force associated with a given wrap profile, with the graphical depictions of each of the number of layers of packaging material and the wrap force being capable of being dynamically updated in response to changes made by an operator to a wrap profile. The graphical depictions therefore provide a visual interface to assist an operator who may have limited expertise in setting up a load wrapping apparatus.

A self-propelled wrapping machine movable on a supporting plane to wrap a load with a film, comprises a self-propelled carriage and an upright fixed to said carriage and slidably supporting an unwinding unit provided with a reel of film; an anchoring element provided with a locking system selectively operable in a closed position or in an open position respectively to tighten or to release an initial flap of the film unwound from the reel; a first gripping unit adapted to position and release the anchoring element with the initial flap of film tightened by the locking system arranged on the supporting plane adjacent to the load in an initial step of the wrapping cycle, and adapted to grasp and lift the anchoring element and activate in an open position the locking system so as to release the initial flap of film after at least one turn travelled by the self-propelled wrapping machine around the load wrapping the load with the film.

A wrapping machine for wrapping material around a load includes a wrapping unit to wrap a portion of the material around the load and a supplying unit to supply the material portion to the wrapping unit. The wrapping unit includes wrapping device to unwind the material portion from the supplying unit and wrap it around the load. The wrapping unit includes a supporting ring, rotating around a wrapping axis and provided with a plurality of wrapping rollers, and an unwinding arm having a first end rotatably fixed to the support ring and a second end supporting at least one unwinding roller to abut and guide the portion of material towards the load during wrapping. The unwinding arm is movable to move the unwinding roller to/from the load during wrapping.

A method and wrapping machine for wrapping a plastic film web from at least one roll on a load with a wrapping machine, wherein the location of the at least one roll of plastic film web in relation to at least the height of the load to be wrapped is detected and monitored during wrapping, one or a plurality of points or locations along the height of the load to be wrapped are preset before starting of the wrapping, at which preset points or locations and/or between said preset points or locations the wrapping characteristics are changed during wrapping.

A load wrapping and transporting vehicle includes a vehicle frame, and a load support is connected to the vehicle frame for supporting a palletized load. An endless track is connected to the vehicle frame and extends about the load support. A spindle supports a roll of wrapping film and is guided by the endless track about the load support to wrap the palletized load with wrapping film dispensed by the roll of wrapping film.

An apparatus for wrapping a wrapping material, which is arranged to run around a wrapping track, includes an assembly and a discharge arrangement at least partly fitted to the assembly for a wrapping-material source. The discharge arrangement includes a support-element arrangement for the wrapping-material source, from which the wrapping material is arranged to be discharged, and drive means arranged to act on the wrapping-material source, in order to maintain the tension in the wrapping material that is discharged from the wrapping-material source. The tension of the wrapping material, from which a tension value as a source of feedback is provided to the drive means, is detected from the discharge arrangement. In addition, a method and system for wrapping a wrapping material, a wrapping device and a control unit are disclosed.
