Abstract: Two superimposed layers of thermally weldable material are welded to one another at welding zones delimiting respective receptacle preforms having respective open ends and connected in series to a transporting strip which extends longitudinally of the processing path of displacement of the receptacle preforms. The goods to be packaged are introduced into the respective receptacle after the two layers of the respective receptacle preform have been separated by blowing a stream of air into the receptacle through the open end thereof. Thereafter, the open end of the receptacle preform is closed and the receptacle preform is severed from the transporting strip to obtain a filled receptacle which is freely transportable. The welding operation is performed by a welding roller which has an electrically resistive conductor wire mounted thereon along such a course that, when developed into the plane of the superimposed layers, the conductor wire will coincide with the zones to be welded.

Abstract: Fresh processed poultry suspended by double leg hooks from conveyor mounted carriers are dropped onto an inclined guide surface of a bagging device having a stack of flexible film bags positioned to receive the dropped birds. Each bird is suspended from its carrier by a hook that pivots downwardly when released, resulting in free fall to an angular impact position substantially matching the incline of the guide surface along which the bird descends into an opened bag.

Abstract: A method for continuous packaging in metal packages produced in situ, the invention comprises the fabrication of aluminum containers from aluminum sheet immediately prior to packaging of a material in the containers, the operations being conducted as part of a continuous flow process. The metal packages are produced by thermoforming, that is, the deformation of a heated metal body in a mold by pressure, thereby resulting in the production of containers which are aseptic and which can be easily coated with a protective layer of a plastic or similar material. The invention is particularly useful for the packaging of perishable produce.

Abstract: Packaging apparatus for making hermetically sealed vacuum packages from two continuous webs of plastic packaging material supplied as roll stock. The lower web is formed into product receptacles, and the upper web is applied over the receptacles to serve as the top. The apparatus includes a single-station evacuate-and-seal head where the two webs are initially sealed together around the flanges of the receptacle. The resulting package is then evacuated through a slit in the lower web, and the evacuation slit is sealed off to complete the package. During evacuation, the upper web is shifted up to engage a heated plate to raise the web temperature to a level permitting forming of the plastic material. After final sealing, the spaces above and below the packages are sequentially vented to atmosphere so as to control the formation of the upper web to produce a crowned effect, wherein a portion of the product extends upwardly a small distance above the flanges of the package.

Abstract: A chub packaging machine, or the like, incorporates a double-knife cut-off or severing device of the invention. Chub packages are elongate tubular packages which are gathered at their opposed ends and have metal clips clinched therearound to close those ends. The double-knife cut-off device is mounted on the closure head assembly of a conventional chub packaging machine, with appropriate modification, and produces a shorter and cleaner stub end on a chub package than heretofore available. The appreciable amounts of product trapped in the stub ends of chub packages formed on conventional chub machines are substantially eliminated by shortening the stub ends to approximately one-third the usual length. The double knife cut-off device severs a short gathered portion of the tubing between two packages at two spaced apart positions rather than in the center of the portion as heretofore known.

Abstract: A machine for filling a cloth bag with cloth filling material having a series of elongated fingers and a hollow spout mounted on a rectangular frame in registry with one another for movement relative to one another along the frame such that the fingers advance into and retract out of the passageway. A cloth filler material is spread upon the fingers and the bag to be filled is draped over the spout so that the inside bottom of the bag is facing the fingers. An air operated double acting cylinder is actuated to drive an endless cable which cable may either be operatively connected to a roller assembly connected to a rear end portion of the fingers or to the spout depending upon whether it is desired to move the fingers into and out of the spout or move the spout along and over the fingers. Movement of the fingers into the spout or vice versa forces the bottom of the bag through the spout and extends the bag over the fingers and the filler material spread thereon.
