  • Patent number: 4972654
    Abstract: A device for closing the upper lateral flaps of long parallelepiped cases includes a pair of helical guides with a reduced longitudinal length and a pair of extension arms controllable so that they may be displaced from an at rest position to an operating position. In the latter position the two arms are arranged as an extension of the helical guides towards the inlet to the device so as to force the lateral flaps of the case to accomplish the closing engagement with the helices.

  • Patent number: 4970845
    Abstract: The present invention relates to a method and an apparatus for a tray arrangement for a series of continuously linked trays. The trays are adapted to be stacked by a twisting mechanism and by a series of curved side guards which twist and bend the links connecting the trays in order to arrange the trays into the proper configuration. The trays are then unstacked by another series of curved side guards and twisting mechanism and then each tray is in turn moved to a filling station where filling material is dispensed therein. The filled tray is then moved to a lid closing station where the attached flipped open lid of the tray is closed atop the tray. The tray is then pulled by a side grasping pull flange to a position where an overhead piston driven mechanism seals the lid and cuts the link, separating the tray from the nested of the trays.

  • Patent number: 4970846
    Abstract: A product support table, having an elongated longitudinal opening is positioned over a pair of fin seal wheels which provide a seal between two edges of a sheet of film that has been wrapped around an article. The product support table supports a pair of product transport belts that are located between the product being wrapped and the product support table. The belts run the length of the product support table generally in contact with the top side of the table and then, on the return run, are directed upwardly to the bottom of the product support table for most of its travel back to a drive roll and a belt take-up roll.

  • Patent number: 4967584
    Abstract: A closed-die forging having an annular flat surface portion and a corner portion at an outer periphery of the annular flat surface portion is made by a method consisting of a rough forging process and a finish forging process. In the rough forging process, a rough forged product is shaped so as to have an annular flat surface portion smaller in outer diameter than the first mentioned annular flat surface portion and a conical surface portion at an outer periphery of the second mentioned annular flat surface portion. The conical surface portion is so shaped as to extend increasingly outwards as it extend in the same direction of movement of a punch of a rough forging die for performing a forming operation.

  • Patent number: 4965986
    Abstract: The invention relates to an apparatus for forming, filling and sealing bag-type packages. For certain filling products it is advantageous to "strip" or flatten the bag-type package prior to sealing, i.e. to ensure that the bag is volumetrically displaced. As a result all bag-type packages are tightly filled despite varying specific weight of the filling product. This object of the invention is achieved by return conveyance or feed of the bag hose or tube and passage of the latter through a constrictive location. An advantage of the apparatus resides in the possibility of achieving high production speeds by virtue of small moved masses.

  • Patent number: 4965981
    Abstract: A shifting apparatus for objects such as eggs comprises a plurality of holders slidably carried on a substantially horizontal holder guide which is vertically movable. When the holder guide assumes an upper position, the holders are maximally spaced from each other for receiving a corresponding number of objects from above. A pitch changing mechanism causes the holders to slide on the holder guide, so that the holders are minimally spaced from each other when the holder guide assumes a lower position. In the lower position of the holder guide, a discharging mechanism causes the holders to discharge the received objects into a container located below.

  • Patent number: 4964262
    Abstract: A capsule filling and capping machine including a testing apparatus for ascertaining the presence of capsule pieces (bottom and cap) in the conveyor apparatus. The conveyor apparatus includes receptacles into which the capsules are tightly inserted. A test head, with chambers disposed in it that communicate with a source of negative pressure or overpressure, respectively, via a throttle is brought into contact with the receptacles, and the pressure of the chambers is monitored by pressure sensors. The output of piezorestrictive pressure sensors is evaluated electronically and processed further into signals to prevent capsules from being filled, to reject defective capsules, or to stop the machine if there is a problem related to one of the capsules.
