  • Efficient handling and charging system for expanded, low-density, loose-fill packaging material(s)
    Patent number: 4284372
    Abstract: A continuous handling and dispensing system for pneumatically conveyable, particulate packaging materials, such as foamed plastic dunnage, involves continuous, air-entrained circulation of the material in an essentially closed loop header installation. The header is most advantageously connected to a plurality of dispensing hoppers. Baffles are employed to deflect gas and material into the hoppers and prevent plugging of the header.
