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.

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.

Insert units (16, 17), disposed on both sides of a moving track for the cardboard shell (10), each have an insert transmitter (19) which removes insert (15) successively from a magazine (18) and swivels the insert (15) to an upright position. The insert-transmitter (19) is moved synchronously with the packaging machine by an operating rod (22), having two double-armed levers (23, 24).

Abstract: A process and apparatus for forming, filling, sealing and deflating a package of goods prior to the time the fill opening is sealed includes a blast of air against the exterior flexible sidewalls of the package to thereby drive gas from the inside of the package.

Abstract: A folder for use in a variety of applications, being especially well suited for folding a sheet of overwrap around a stack of paper pulp sheets, includes three stationary folder sections and an extensible folding plate which performs the back tucking function. The plate is arranged to fold the back edge inwardly as the bale is moved along a conveyor line. After the rear edge has been folded inwardly, the bale slides past three stationary folder devices which in turn fold the front, bottom and top flaps of the overwrap. The folded package is then secured by conventional strapping techniques.

Abstract: The present invention involves a method of packaging a product including drawing a thermoplastic thermoformable web into a thermoforming mold to form a cavity, inserting the product into the cavity, moving the web and product to a vacuum chamber, placing a tray, upside down, in the chamber on top of the web to define an unsealed package; sealing the tray to the web under vacuum; and shrinking the bottom web.

On either side of the plane of a strapping frame (4) in an automatic strapping machine (1) are provided folding means (7) for a cardboard package blank (5) as well as vertically movable press members (10) for holding a book package (6) stationary during the folding of cardboard (5) and for pressing and holding the folded cardboard against the top surface of a book package at the same time as the strapping machine winds a strapping band around said package (5, 6).

Abstract: A resealable hermetically sealed package for food products has the product contained between two sheets of thermoplastic material which are sealed together by a permanent heat fused seal about the product except for one edge along which the sheets are adhesively glued together by an easily peeled resealable seal. The process for manufacturing the product forms the adhesive seal prior to the permanent seals in an area remote from that in which evacuation and the final seal occurs. Thus, the final sealing and evacuation of the package is performed in the absence of adhesive so that no adhesive can be drawn into evacuation slots so as to economically produce the product.

Abstract: An article is wrapped in a shrink film having a longitudinal seal. The longitudinal seal is formed by swirling hot melt fibers onto a longitudinal edge of the film and bringing longitudinal edges together to form an initial pressure-sensitive seal. The shrink film and hot melt are then subjected to the elevated temperature of shrink oven to shrink the film and to form a more complete bond at the longitudinal seam.

Abstract: A device for introducing material into containers with a material-release mechanism and with a structure that supports a container below the material-release mechanism and that can advance the container past the material-release mechanism. The supporting structure has a rocker bearing on which the container rocks back and forth. The point at which it supports the container is displaced to the rear as the container travels forward such that the displacement in the center of gravity of the container as it fills up both occasions an advance in relation to the material-release mechanism and brakes it as the container advances.

Abstract: A method for making easily openable foil packages. The method comprises the step of forming a longitudinal seam and a transverse seam intersecting with each other, thereby providing grip surfaces which, when pulled apart, break the seal. The apparatus for forming the seam comprises bifurcated tool elements which come together in two orthogonal steps. The package so formed by the apparatus operating in accordance with the method is also novel.

Abstract: The continuously formed wrapping material tube traversing a horizontal wrapping machine, and containing articles to be wrapped therein, is sequentially passed between a first pair of opposed, counter-rotating heat sealing bar sets, and then between a second pair of opposed, counter-rotating combination heat sealing and cutting bar sets, to heat seal and cut spaced apart longitudinal sections of the tube, each positioned between an adjacent pair of articles, to form individual, article-containing packages. As each of these longitudinal tube sections passes through the first bar set, corrugated outer ends of two bars therein mesh to compress and heat seal the tube section along a corrugated heat seal area whose ridges and valleys extend transversely to the tube length.

Abstract: There is disclosed an apparatus for forming a shrink-wrapped package from polyolefin film which overcomes the problems of forming the bottom lap seal of the tubular package formed from the film and initial low strength of the heat seal at the forward end of the package, by positioning the static sealer for the bottom lap seal upstream from the heat sealer for the forward end of the package and by using a ram to move packages into the tubular package but to stop them short of the heat seal at the forward end of the package.

Abstract: A container sealing machine for placing an elastomeric lid with a transverse wall and a depending sidewall upon the open upper end of the container has a frame providing a cavity adapted to receive therein the upper portion of the container. A multiplicity of stretching fingers are movably mounted on the frame and extend inwardly of the cavity. The fingers have upstanding lips at their inner ends adapted to engage the inside surface of the sidewall of the lid and are movable relative to the cavity. Initially, this movement stretches the lid and thereafter it causes the sidewall of the lid to be moved off the lips, and the sidewall of the lid then contracts against the sidewall of the container to effect its sealing. Generally, the finger moving means includes a base plate on which the fingers are slidably seated, a base plate on which the fingers are slidably seated, and a rotatable cam ring above the fingers which cooperate to produce the movement of the fingers.
