  • Patent number: 5400493
    Abstract: A bale debanding method and apparatus comprising a band breaking blade, a band winding mandrel and a mandrel cleaning plate are mounted to a frame. A support table is attached to the frame for receiving a waste paper bale that is held together by banding material. As the bale is moved past the band breaking blade, a band retention notch engages a band and by stretching it breaks the band. Once a band is broken, an extensible band catch extending out of the mandrel contacts the band and facilitates the band in being wound around the mandrel. Once all of the bands have been removed from the bale, the band catch is retracted to a position within the mandrel and a cleaning plate is moved axially along the mandrel sweeping the bands off a free end of the mandrel. This process is repeated to remove bands from other surfaces of the bale, thereby releasing the waste paper in preparation of processing.
