摘要： The present invention relates to a method of wrapping a load, comprising:
providing a film dispenser for dispensing film;
operating a rotational drive to provide relative rotation between the film dispenser and the load during a wrapping cycle;
operating a film dispensing drive of the film dispenser to dispense the film during the wrapping cycle;
sensing a demand for film for wrapping the load by monitoring a speed of an idle roller configured to rotatably engage the dispensed film downstream_of a prestretch portion of the film dispenser; and
adjusting the film dispensing drive to control a speed of film dispensing based on the monitored speed of the idle roller.
