  • Patent number: 8407972
    Abstract: A container sealing apparatus 10 comprises an electrically conductive linearly displaceable cutting member 14 operable to cut a portion 18 of sealing material from a web 16 and an independently linearly displaceable transfer member 42 comprising an electrically insulating material and extendible relative to the cutting member 14 to transfer the cut portion 18 of sealing material to an open top of a container 12 to be sealed. An induction coil 52 produces an induction field 54 for heating the cut portion 18 of sealing material, either directly or indirectly, by induction heating to seal the cut portion 18 of sealing material to the open top of the container 12. The linearly displaceable transfer member 42 holds the cut portion 18 of sealing material against the open top of the container 12 during induction heating.

  • Publication number: 20120321415
    Abstract: A metal end is applied and sealed to a plastic or paper/plastic composite container body by a crimp-seaming or double-seaming operation. The metal end has an outer curl joined to a compound-angle chuck wall that extends down from the curl. The chuck wall has an upper part that is substantially linear and at an angle ?1 with respect to an axis of the end, and a lower part that is substantially linear and at a larger angle ?2 with respect to the axis. The compound-angle chuck wall allows a substantial diametral clearance between a lower end of the lower part of the chuck wall and the inner surface of the container body, while there is substantially zero clearance, or preferably an interference fit, between the upper part of the chuck wall and the inner surface of the container body. Accordingly, the chuck wall guides the end into concentric alignment with the container body during application.

  • Patent number: 5778630
    Abstract: A device is used in a machine for packaging articles in a wraparound carrier. The carrier is formed from a blank having a pair of foldable flaps struck therefrom. The packaging machine is arranged to advance the blank and articles associated therewith along a predetermined path. The device is positioned along the path to fold the flaps inwardly of the blank. The device includes a rotational disc defining an axis of rotation, a fixed cam plate disposed adjacent to the rotational disc and having an endless cam track disposed around the axis, drive means for rotating the rotational disc about the axis in synchronization with movement of the blank and the articles, a pair of blank-engaging fingers carried by the rotational disc for pivotal movement about respective pins so as to engage the flaps, and an actuating mechanism carried by the rotational disc to pivotally move the fingers away from each other and toward each other.

  • Patent number: 5765336
    Abstract: A tray packing-shrink wrapping machine for packaging articles along a conveyor is disclosed. The machine is operable in a dual lane mode and a single lane mode. In both modes a collation section receives articles from an infeed section and arranges the articles into rows and columns to create batches of articles. In dual lane mode a lane divider structure separates each batch into smaller microbatches. Separate trays and sheets of heat shrinkable film are simultaneously formed around the microbatches. An in-line stacker is selectively operable in single lane or dual lane modes to stack a packed tray on top of the preceding packed tray. The machine is quickly converted to single lane mode by removing the lane divider structure and center trayforming structures, removing the center stacker elements and retracting knives in the blank feeding and film wrapping devices. A method for converting a dual lane machine to a single lane machine is also disclosed.

  • Patent number: 5673536
    Abstract: A carton flap folding method and apparatus for use on a continuous motion packaging machine is disclosed. The carton flap folding apparatus includes a spaced pair of generally parallel knock-down arms which are rotated in the direction of a path of travel extending along the packaging machine and on which a spaced series of groups of articles for being packaged are moved. Each group of articles is at least partially enclosed in a carton blank having at least one flap hingedly connected thereto for being closed on at least a portion of the group of articles. The carton flap folding apparatus moves the knock-down arms into engagement with the at least one open flap of the carton blanks in the direction of the path of travel at substantially the same speed as the speed of the group of articles along the path of travel.
