  • Patent number: 6397557
    Abstract: A packaging machine includes a fixed structure. A number of forming assemblies are arranged successively along a vertical portion of a path of a strip of packaging material, for gradually superimposing opposite lateral portions of the strip to form a tube having a longitudinal axis. A sealing device seals the lateral portions to each other and forms a longitudinal seam of the tube. An actuating device is operatively connected to an angularly adjustable folding member of one of the forming assemblies, and activated selectively to rotate the folding member about the longitudinal axis. A sensor is disposed along the vertical portion of the path, downstream from the sealing device, and generates a position signal correlated to the angular position of the seam. A control unit receives the position signal and generates a control signal, which is supplied to the actuating device to restore the seam to the desired angular position.

    Abstract: In a cross joining and/or cross cutting station in a flow packing machine, opposed tool parts are moved in complementary round paths such that they can press against opposite sides of a tubular packaging web for cross closing/cutting the web between successively advanced products therein, during continuous movement of the web. Normally the tool parts are moved by simple rotation, but according to the invention they are moved in a paracyclic manner, i.e. with substantially unchanged orientation in the space. This makes it possible to maintain the tool carrying parts in operative connection with an external power source through flexible wires or hoses, such that in a packaging machine with more packaging lines it is possible to operate all of the tool sets by common moving means, yet also with the possibility of deactuating the tools individually in case of operational disturbances in one or more of the lines.

The converter functions with both horizontal and vertical form/fill/seal wrapping machines and with overwrap packagers, and uses diverse packaging films such as polypropylene, polyester, polyvinyl chloride, high and medium density polyethylene and various film laminations.

  • Patent number: 5927052
    Abstract: A method for flavoring tea with a granular flavoring agent includes the step of removing from a reservoir a predetermined amount of granular flavoring agent. The predetermined amount of granular flavoring agent is placed as a small heap onto a moving endless filter paper strip. Subsequently, a predetermined amount of tea is placed adjacent to or onto the small heap of flavoring agent. The tea and flavoring agent heaped onto the filter paper strip are subsequently enclosed in a tea bag made from the filter paper strip accordingly. The inventive device for performing the method includes a device for moving the endless filter paper strip in an advancing direction. A tea metering device and a metering device for a flavoring agent are positioned directly above the endless filter paper strip whereby the metering device for the flavoring agent is positioned upstream of the tea metering device in the advancing direction.

  • Patent number: 5924268
    Abstract: As a cylindrically formed web of thermoplastic bag-making material is transported longitudinally along a path at a specified speed, a longitudinal sealer with a heater is compressed against and over portions of the material parallel to the path to effect longitudinal sealing. The longitudinal sealer is moved in the meantime along the path at a greater speed in the range of 1.05 to 1.30 times the specified speed of motion of the material such that generation of V-shaped wrinkles known as the chevrons on both sides of the sealed area can be prevented.

  • Patent number: 5921067
    Abstract: A pillow type packaging apparatus has a suction belt for conveying flexible continuous sheet material. A guide unit guides the continuous sheet material being conveyed, and forms the continuous sheet material into a quadrangular tube in which a pair of its longitudinal edges are confronted with each other. A center sealer thermally seals up the longitudinal edges. An inserter inserts an article into the tube through the guide unit. The tube is formed into a packaging bag by cutting and sealing. In the guide unit, an inner guide frame is inside an outer guide frame. The outer guide frame includes first to fourth corner portions, which are disposed in a quadrangular shape, having inside edges in contact with the continuous sheet material, and shape the continuous sheet material into the tube. The first to fourth corner portions are movable in directions of width and height of the continuous sheet material. The tube is changeable in size.

    Abstract: An end seal wrapping machine (10), and method of forming an end seal in a spaced series of articles (A) moved therethrough, is disclosed. The wrapping machine has a first rotating shaft (40) on which at least a first upper sealing and crimping head (41a, 41b) is positioned, with a spaced second counter-rotating shaft (81) on which a second opposed sealing and crimping head (82a, 82b) is positioned. The wrapping machine is supplied with a regularly spaced series of articles which are substantially enclosed in a continuous tube (27) of packaging film (20) upstream of the sealing and crimping heads. The articles in the tube of packaging film are passed between the sealing and crimping heads for being wrapped within the film. The first sealing and crimping head includes an elongate knife (43) formed as a part thereof, with an elongate platen (92) formed as a part of the second sealing and crimping head, and opposed to the knife.

  • Patent number: 5875610
    Abstract: In a drug packaging device which can shorten the drug packaging time. The opening of a bag is sealed with a transverse sealing unit and a longitudinal sealing unit. The time when the sealing is started and the sealing speed are varied according to the type of drug to be packaged in the bag. For drugs that take a longer time to be fed into the bag and settle in the bag, the seal starting time is delayed and the sealing speed is slowed. As a whole, it is possible to shorten the packaging time, while eliminating the possibility of incomplete packaging.

  • Patent number: 5852920
    Abstract: A form-fill-seal machine in which an heated longitudinal seam sealer continuously forms a longitudinal seam along lapped edges of the tube being formed. This longitudinal seam sealer can be used in machines having conventional cross sealing jaws as well as in machines in which the cross sealing jaws move in the direction of the moving film during the cross sealing operation. The heated longitudinal seam sealer includes a pair of sealer bars that include shaped confronting portions. The shaped confronting portions are heated and seal the lapped edges to form a seam. After exiting the shaped confronting portions the seam is engaged by a pair of pressure rollers that force the heated edges together to insure complete closure of the seam. The lapped edges of the film pass between the shaped confronting portions of the sealer bars which confine the lapped edges to a labyrinth cross section shape.
