  • Patent number: 6951088
    Abstract: A banding machine and method for banding bundles of material using a thermal and moisture activated adhesive baleband. In one embodiment the banding machine includes a sealing station that guides and tightens the baleband around a bale such that a portion of the baleband is overlapped. The sealing station also connects or seals the overlapped end portions of the band after tightening the band about a bale and cuts the band as overlapped end portions are connected. The overlapped end portions are adhesively connected or sealed using a steam or hot water applicator mechanism and associated actuator controller for applying pressurized steam or hot water to the overlapped end portions of the baleband.
