  • Stretch bundler
    Patent number: 4850177
    Abstract: This invention relates to a stretch bundler having a novel film-holding device. The bundler has a rotable ring that holds the film in a spool and as it rotates it wraps the film around the object to be wrapped or bundled. The film is held at the beginning of the process by a device that firmly holds the sides of the film and stretches these sides outwardly. The subsequent wraps of film are thereby free of any obstructions.
