Abstract
A method and apparatus for securing an initial tail of film to a load while wrapping the load with packaging material are provided. The method includes holding a leading end of packaging material while providing relative rotation between the load and the dispenser to wrap film around the load. A portion of the leading end of film is secured to a fixed wrapping structure while the leading end of the film is held. After the leading end is secured to the fixed wrapping structure, the leading end of the film is released. The released leading end of the film is then secured to the load. The apparatus holds a leading end of packaging material and provides relative rotation between the load and a dispenser to dispense packaging material. The apparatus also secures a held leading end of packaging material and secures a released leading end of packaging material between two layers of packaging material. A method and apparatus for securing a final tail of film to the load also are provided.
