  • Patent number: 7914239
    Abstract: A conveyance system comprises a production machine for manufacturing a web of packaging cushions, a duct downstream from the production machine, a blower to provide an air flow through the duct to apply a conveyance force for conveying the web of packaging cushions, and a friction contact area downstream from the production machine and upstream from the duct entrance. The web of packaging cushions passes beneath and contacts the friction contact area to create a friction force opposing the conveyance force so that the conveyance force is not transmitted along the web of packaging cushions to the production machine.
    Type: Grant

  • Patent number: 7273142
    Abstract: A system for conveying a string of packaging cushions includes a machine capable of manufacturing the string and a conveyor adapted to transport the string. The conveyor has an inlet end to receive the string and an outlet end to deliver the string of packaging cushions. The inlet end of the conveyor is higher than the cushion outlet elevation of the machine. At least one pair of rolls are adapted to lift the string of packaging cushions from the machine through the nip of the rolls to the conveyor inlet elevation.

  • Patent number: 7231749
    Abstract: The invention is an under-filled cushion detector that is capable of conveying a string of packaging cushions and detecting whether the string of packaging cushions may be under-filled. The detector includes an upper driven belt that is movably suspended above a lower belt. The belts cooperate together to define a longitudinal cushion pathway between the belts. The distance between the upper and lower belts may vary depending upon the thickness of the string of packaging cushions. If a string of under-filled cushions travels between the upper and lower belts, the upper belt can move downwardly in the direction of the lower belt. A switch stops the upper and lower belts if the height of the cushion pathway decreases below a predetermined threshold. The detector can be used in a system for manufacturing and transporting packaging cushions to a desired location.

  • Patent number: 6996955
    Abstract: There is provided a system that automatically delivers, monitors and replenishes a string of packaging cushions to hoppers located at multiple packing stations through an elongated cushion delivery duct having a series of intermediate outlets to permit the string of cushions to drop into the hopper located below the delivery duct and above the packing station. A blower is positioned near the inlet of the elongated duct to provide air flow in the duct to carry the string of cushions through the duct to one of the outlets. When the hopper is full of cushions sensors signal the controller to close the diverter and the string of cushions is delivered to another packaging station. The system may include a knife assembly to cut the string of cushions holding pins and the tension-relief diverter it is located at the inlet of the duct to hold tension on the string of cushions while the string is being separated.

  • Publication number: 20050210839
    Abstract: A system for supplying packaging cushions manufactured from cushion feedstock comprises a lift, a cushion-supply machine moveably supported by the lift, and a hopper. The elevation of the hopper entrance opening is higher than the elevation of the hopper exit opening. The lift is adapted to move the cushion-supply machine between a supply position, in which the elevation of the cushion outlet of the cushion-supply machine is higher than the elevation of the hopper entrance opening, and a reload position, in which the elevation of the cushion-supply machine cushion outlet is lower than the elevation of the hopper entrance opening.
