  • Patent number: 4747253
    Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. During the forming, which is done by means of external forming devices, the contents are made use of as an internal mandrel or a holder-up for the forming devices, so that the desired shape can be achieved without creasing or other deformations. The above-mentioned forming principle works less well if the packing containers are not to be completely filled but have a certain air space or headspace. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved.

A fixed, upstanding, flat, holder and an inclined, spring-biased, pivoted, flat, holder are mounted at a predetermined distance above the level of the conveyor path to support an open band. The operator tears off a band, places it over the holders, presses a pedal which causes a piston head to lift the container at the station, up through the holders for frictional engagement within the band. The banded container is removed and the parts return for the next cycle. A gear rack and pinion mechanism advances the bands individually and successively over a spreader to a tear-off location at about eye level. The spreader includes oppositely disposed concave recesses in each of which one of the oppositely disposed feed rolls is seated.

  • Patent number: 4338761
    Abstract: A machine for making packages with labels is provided. The packaging machine utilizes a supply of packaging material in the form of a length of plain plastic tubing and a supply of labels in the form of a continuous strip thereof. In a previous cycle of the machine, the tubing was heat sealed along a transverse strip near the leading edge thereof. The strip is subsequently advanced a predetermined distance between a first set of jaws which close, with a first sealing wire carried by one of the jaws then energized to seal a leading edge of the tubing which will form the next package. A knife severs the tubing below that seal and the upper edges of the severed section which has been advanced are engaged by clamps. These move apart with the jaws to open the upper edges, thereby enabling an article to be dropped into the resulting pocket in the severed package section. The jaws then close once again and a second sealing wire below the clamps seals the upper edges of the severed section.

  • Patent number: 4244159
    Abstract: A packaging machine for packaging articles is provided. The packaging machine employs a source of packaging material in the form of a length of plain plastic tubing. The machine is relatively simple and maintenance free, employing but one station. In a previous cycle, the tubing is heat sealed along a strip extending transversely thereof at a leading edge. The strip is then advanced a predetermined distance between a movable jaw and a stationary jaw at the station and the movable jaw closes against the stationary one. At this time, an upper sealing wire is energized to seal a leading edge of the tubing which will form the next package. A knife severs the tubing below that seal and the upper edges of the severed section are engaged by clamps. The movable jaw then opens to enable an article to be dropped in the resulting pocket in the severed section. The movable jaw closes once again and a lower sealing wire seals the upper edges of the severed section, below the severed edges thereof.
