  • Patent number: 5775055
    Abstract: An anvil system including a plurality of anvils having an interconnected cooling system. Each of the anvils has a means for acoustically insulating the anvil body from ultrasonic energy which originates from a ultrasonic horn. The insulation means may be a airspace slot essentially separating the vibrating portion of the anvil from the anvil body. The anvil may also have an adjustable sealing pattern which allows for facilitated exchange of sealing patterns. The anvil may also have a plurality of projecting pads which reduces damage to the ultrasonic sealing equipment and to the object to be sealed.

  • Patent number: 5551211
    Abstract: An apparatus for forming a flattened seating area from a gabled bottom of a carton. The apparatus includes a cup having a recess that conforms to the bottom cross-section of the gabled bottom. The cup has an inlet in fluid communication with an underpressure source. An anvil is disposed within the cup recess for forming the carton when the carton bottom and anvil are driven together by, for example, the underpressure in the cup.

  • Patent number: 5549191
    Abstract: A mechanism is provided for transferring containers from a packaging machine to a pair of continuously moving outfeed conveyors which then route the containers to another location in the packaging facility. The packaging machine includes a vacuum cup which carries a row of container. The vacuum cup is movable to position the row of containers in place in front of a pair of pusher plates. The pusher plates are driven transversely across the vacuum cup to transfer the containers to a pair of puller plates positioned on the opposite side of the vacuum cup. As the pusher plates extend, they push the containers against sidewalls on the puller plates, aligning the cartons in rows running parallel to the outfeed conveyors. The puller plates then move transversely to align the rows of cartons with the outfeed conveyor. Once the puller plates are aligned with the conveyors, an unloader mechanism pushes in the containers onto the outfeed conveyors.
