    Abstract: A method comprises pulling a continuous web to advance the web along a path of conveyance and to create tension in a lengthwise portion of the web; manipulating the web to cause the portion of the web at a point along the path to have a non-uniform tension across the width of the web, with a maximum tension being at a location spaced from the first longitudinal edge of the web, and with the tension decreasing from such location toward the first longitudinal edge of the web such that a zone in the web at the first longitudinal edge has reduced tension; and controlling transverse positioning of the first longitudinal edge in the zone of reduced tension. The reduced-tension zone is produced by a tension-reducing member about which the web is pulled.

  • Patent number: 6751926
    Abstract: A machine for producing a packaging filler material employing inflated pouches or cells fabricated from a tubular supply of plastic-like material having a top and bottom integral fold so that a pair of sheets are defined with their opposing inner surfaces establishing a compartment. Sealed strips, which are spaced apart in parallel relationship, define the sides of each pouch compartment. The machine includes a first work station having a source of tubular material that is introduced to a second or cutter station for severing the top fold of the tubular material followed by introduction to a third or inflation station where a source of pressurized fluid is fed to the pouch compartment. A sealing station follows the inflation station where the top opening to the pouch is closed such as by heat sealing. Idler rollers smoothly conduct the material past each of the respective work stations in a serial fashion and provide a gap for effecting inflation.

  • Patent number: 6694709
    Abstract: An apparatus to charge and seal in contents is provided with a supporting portion for containers, holding portions for seal plugs, airtight chambers, a pressure gas supplier and a vacuum pump. The container has a receiving chamber and it is to be put on the supporting portion being the chamber is charged with contents and being the chamber's opening portion faced upward. The seal plug is for sealing the opening portion. The airtight chamber is composed of a main portion and a cap portion. The main and cap portions freely move relatively and freely contact tightly, then they surround the supporting and the holding portions in airtight condition. Further, the supporting portion and the main portion freely move relatively in airtight condition, so as the holding portion and the cap portion do, and the supporting portion and the holding portion are freely separated from each other.

  • Patent number: 6672037
    Abstract: A system for providing dunnage to packages as the packages are formed is disclosed. The system includes a dunnage forming machine having a work station for inflating and sealing plastic pouches to form dunnage units. An accumulator is positioned below the station for receiving and collecting such units as they are formed. The accumulator includes an outlet opening laterally offset from the station. A pair of counter rotating brushes having axes journaled in spaced relationship are mounted at the outlet. Each of the brushes includes circumferentially spaced bristle sets defining unit receiving spaces between adjacent sets. A motor drive is operably connected to the brushes for causing counter rotation. A unit volume sensor is provided for emitting a machine start signal when the volume of units in the accumulator reaches a predetermined low volume. A process for providing dunnage in packages being formed is also disclosed.

  • Patent number: 6672033
    Abstract: System for delivering air-filled packing cushions to a point of use in which a continuous string of the cushions is fed into an elongated duct with the string extending longitudinally of the duct, and an air flow is established in the duct to convey the string of cushions through the duct. In one disclosed embodiment, the air flow is created by a blower mounted externally of the duct, with a baffle plate inside the duct directing the air flow in a longitudinal direction. In a self-contained system in which the cushions are made at the point of use, the duct extends vertically, and the cushions are fed directly into the lower end of the duct by a machine which makes them.

  • Patent number: 6662527
    Abstract: A tube film grip-pressing time by a pair of seal bars is controlled to set longer. A crank mechanism allows a seal bar frame supported by a pair of rails to reciprocate along the rails. The crank mechanism includes an arm which supports one end support shaft and is capable of swinging, and a circular crank plate which is rotated by power of a center shaft. The crank mechanism is fixed to a crankshaft which rotatably supports a groove-like slide which is engaged with a slide guide formed along a longitudinal direction of a lower surface of the arm on an eccentric portion of the crank plate. A top dead center and a bottom dead center of the arm are formed respectively &thgr;1 and &thgr;2 beyond a 180° region connected across a center shaft that, is a. A servo motor which drives the center shaft controls speed in the point 55 to point 56 region having a radius of 180° to make the speed constant, and cause the frame to advance along rails and then move backward at a high speed.

  • Publication number: 20030205026
    Abstract: An inflator/sealer machine useful for inflating and sealing an inflatable cushion having a resistance wire that extends across the inlet of the inflatable cushion. The machine includes an inflation tube, a seal bar, and an anvil. The inflation tube is connected to a source of inflation fluid and has an outlet that is larger than the inflation aperture of the inflatable cushion. The inflation tube and anvil are adjustable between a tube/anvil engaged position and a tube/anvil disengaged position. In the tube/anvil engaged position, the inflation tube outlet opposes the anvil and can engage the inflation aperture of the inflatable cushion between the inflation tube and the anvil to inflate the cushion. The seal bar and the anvil are adjustable between a bar/anvil engaged position and a bar/anvil disengaged position. In the bar/anvil engaged position, the anvil opposes the seal bar to compress the inlet heat seal zone of the inflatable cushion between the anvil and the seal bar.

  • Patent number: 6634394
    Abstract: The present invention provides an inflation block for a balloon inflation device including an inflation nozzle that is operatively connected to a source of pressurized gas, and a trough that substantially encloses the inflation nozzle in order to prevent access thereto by an operator's mouth, yet allowing for the insertion of the neck of a balloon thereon. The inflation nozzle is operatively connected to a slide valve that has a closed position and an open position. The slide valve is located between a source of pressurized gas and the inflation nozzle such that, in its closed position, the slide valve blocks the flow of gas from the source of pressurized gas through the inflation nozzle, and, in its open position, the slide valve opens the flow of gas from the source of pressurized gas through the inflation nozzle, in order to allow for the inflation of a balloon having its neck placed over the inflation nozzle.
