  • Patent number: 6308493
    Abstract: A control system and control method for use in a machine for wrapping an article in plastic film are disclosed, the machine including a sealing head and a corresponding anvil movable by a pneumatic cylinder from an initial separated position to a contact position. The cylinder has an air exhaust outlet for exhausting air from the cylinder during operation of the cylinder from its initial state to an actuated state. A selectively actuatable valve disposed in the outlet selectively directs exhausting air through a first path of relatively low airflow resistance and a second path of relatively high airflow resistance. The valve directs exhaust air flow from the first path into the second path during operation of the cylinder and just prior to the cylinder being placed in the actuated state to cushion contact between the head and anvil.

  • Patent number: 6226963
    Abstract: Valving employed to control side closing elements of bag clamping apparatus of a bag filling machine is altered to cause the elements to move slowly to close the sides of a bag being filled whereby air is permitted to escape externally through slowly closing openings at the sides of the bag. At a predetermined time determined by the size and contents of the bag the openings are closed rapidly thereby sealing the bag once fitted.

  • Patent number: 6185911
    Abstract: The invention concerns a method for filling a two chamber tube made from plastic having a substantially circular cross section and a separation wall made from plastic and extending between two substantially diametrically opposed connecting points of the separation wall and having a length in excess of the diameter of the tube to form, together with the wall of the tube, the two chambers. A filling nozzle is inserted into each chamber for introducing the filling product into the tube and the tube is sealed after removal of the filling nozzles. In order to guarantee reliable filling of the two chamber tube, the separation wall is attached, prior to introduction of the filling nozzles, to the inside tube wall at its end regions bordering the connecting points in such a fashion that the length of the middle region remaining between the two end regions corresponds substantially to the diameter of the tube.

  • Patent number: 6182425
    Abstract: Upon filling cans with fiber band, the movable bottom of the cans, as the filling process proceeds, moves downwardly from an initial upper to a lower final position. As this happens, between two elements, one inside, one outside the circumferential shell of the can, a force field is built up in such a way that the element inside the can supports the can bottom and because of the force field, this bottom is held at the same elevation as the element outside of the can. Further, the desired operating height of the can bottom can be correspondingly held. For the lowering of the can bottom, one of the two elements between which the force field exists, is moved relative to the other in the direction of the lower final positioning of the can bottom and the remaining element follows after, because of said force field, until both elements again stand across from one another at the same height.

  • Patent number: 6131376
    Abstract: A cushioned shipping assembly includes a carton and foam inserts to support a product shipped by a supplier, which elements are successively returned by an end user to be reused in the same or other shipping assembly, while various components are recycled as they become spent. In some embodiments, the carton collapses to a diminished size for return. A resource center reroutes or refurbishes the components, recycling aged or spend pieces. On-premises pelletizing of reclaimed polymer provides a more efficient, environmentally clean system. Spent inserts of identified polymer may be diverted to users of specific resins.

  • Patent number: 6131375
    Abstract: A protective foam cushion-making apparatus dispenses reactive foam components into an interior space between two panels of plastic film to form protective foam cushions. The apparatus includes a supply of plastic film and a film a driving assembly, such as two pliable rollers. A foam component dispensing assembly is interposed between the film panels and injects reactive foam components into the interior space where they are mixed together to form a mass of expandable foam. The plastic film forms a flexible mixing chamber in the area between the two pliable rollers in which the reactive foam components are mixed together after they are dispensed from the foam dispensing assembly.

  • Patent number: 6125611
    Abstract: For the manufacture of soft-pouch packets for cigarettes, folding mandrels (10) configured as hollow bodies are used, on the outer side of which blanks (16, 17) are folded. The outer blank (17) has in the region of one narrow side wall (15) blank portions (23, 24) which overlap one another and are connected to one another by gluing. In the region of the glue connection, there is slight expansion of the cross-section of the package during the hardening of the adhesive. To compensate for this effect, the folding mandrel (10) does not have an exactly rectangular shape. Rather, the narrow side wall (15) adjoining the gluing point has a smaller width (B.sub.15) than the opposite narrow side wall (14).
