Abstract: There is provided a device for filling an inflatable protective cushion to a predetermined air pressure. The inflating device has a handle having an inlet port for receiving compressed air and a valve for opening and closing the inlet port and an air outlet port. A housing having an air chamber is connected to the handle and receives the air from the handle outlet port through an air channel terminating in an orfice which creates a vacuum in the chamber. The venturi effect draws additional air through a muffler connected to the housing chamber during filling. The muffler serves to restrict air flow from and to the atmosphere during and after filling of the cushion. The housing also includes a nozzle connected to the air outlet for insertion into a self-sealing valve in the cushion for filling with air. Also provided is a fill indicator comprising an indicator mount secured in the housing, an indicator button extending through an opening in the mount and moveable upward and downward therein.

Abstract: A dispensing apparatus for serially dispensing plastic bags from a wound roll of continuous flexible plastic bags joined along perforated severance lines. A container is provided which is adapted to receive the wound roll of plastic bags. The container has a bottom, a pair of opposed sides having an inwardly facing flange extending therefrom, and a separating tongue projecting outward from the bottom. The flanges define a self-threading slide for threading the plastic bags from the wound roll along a predetermined path onto the separating tongue. The separating tongue separates the plastic bags from the wound roll as the plastic bags engage the separation tongue along a predetermined path of travel.

Abstract: An apparatus and method are disclosed for successively forming foam filled cushions for packaging purposes of the type in which a bag containing foam precursors is added to a container so that as the foam precursors form foam, the bag forms a custom cushion adjacent objects in the container. The method comprises attaching an adhesive strip to the longitudinal edges of a pair of sheets of plastic film material being advanced along predetermined paths of travel in face to face contact from a stock supply, and between which sheets a foamable composition is injected, to thereby join the sheets together and form one edge of the bag, while periodically sealing the leading edge and the trailing edge of the sheets together transversely to the path of travel to form a bag while periodically severing a completed bag from the next succeeding bag being formed.

Abstract: An apparatus and method is disclosed for successively forming foam filled bags or cushions of the type wherein a foamable composition is deposited in a plastic bag. The method and apparatus includes advancing a pair of plastic webs along a substantially horizontal path of travel and through the nip of a pair of drive rollers, while heat sealing the opposing longitudinal side edges of the webs together. Periodically, a predetermined amount of the foamable composition is deposited between the advancing webs from a position offset from the center of the pair of plastic webs and the heat sealing along the side edges is periodically and momentarily interrupted to form side edge openings for the subsequent escapement of gases generated during foaming. The advance of the webs is momentarily terminated, and a heated wire then engages the webs to sever the formed bag, while forming a sealed top edge of the formed bag and a sealed bottom edge for the next succeeding bag.

Abstract: A method and apparatus for successively forming, opening, filling and sealing plastic bags formed from a stock supply of plastic tubing and characterized by the elimination of handling of cut bags during formation and filling.

Abstract: A tape feeding apparatus is provided for preventing the feeding of successive strips of tape unless and until the manual activator for the tape feeding mechanism has been allowed to return to its manual in operative position. There is a tape feeding apparatus, a drive apparatus for driving the tape feeding apparatus, and a clutch interposed there between. A latching mechanism normally maintains the clutch disengaged to prevent the driving apparatus from driving the tape feeding apparatus. A second clutch is interposed between the latching mechanism and a manually movable actuator for normally engaging and providing a direct connection between the movable actuator and the latching mechanism so as to disable the latching mechanism when the actuator is moved to the actuating position, and thus allowing the first clutch to engage and cause the driving apparatus to drive the tape feeding apparatus.

Abstract: A latching mechanism for releasably joining and locking together two separate modules located on a flat surface. The latching mechanism includes a first module having a pair of lower fingers projecting therefrom and a pair of upper angular, locking members projecting therefrom, a second module having a pair of lower apertures for locking engagement with the pair of lower fingers and a pair of upper apertures for locking engagement with the pair of upper, angular, locking members and a cam rotatably mounted in the lower portion of the first module. The cam has a shape such that rotation of the cam is effective to lower the first module onto the second module to thereby join the two modules and continued rotation of the cam is effective to urge the second module upwardly against the first module to thereby rigidly lock together the two modules.

Abstract: An envelope flap sealing device in a mailing machine, including a moistener separator blade, a moistening brush attached to and located downstream of the separator blade, at least one pair of feed rollers for transporting envelopes past the moistening brush, a pivotable, deflecting baffle situated intermediate the feed rollers and the separator blade, and a cam operatively connected to the deflecting baffle for pivoting the baffle about its downstream end whereby the upstream end of the baffle is translatable between a raised position and a flat position, wherein the raised position guides an envelope flap under the moistening brush to thereby seal the flap and the flat position causes the envelope flap to pass over the moistening brush and not be sealed.
