Abstract: A device for the packaging of powder, granulates, slurries and viscous materials in a tubular film which is formed from an endless web of film by a forming shoulder into a tube which is filled by means of a filling pipe with the material to be packaged and subdivided at intervals by transverse closures which are formed by a clamp which is moved against the tubular film transverse to the direction of film movement by two cooperating gathering irons which are moved against the tubular film from opposite sides, to gather the tubular film and therby form the transverse closure.

Abstract: A form, fill and seal machine packages products in a thermoplastic material which is formed into a tube and sealed with a measured amount of the product within. The transverse seals in the tube are formed in a cyclic operation by a pair of cooperating sealing heads. The heads clamp the tube walls together above and below a line of severance between two sequentially formed packages and weld the tube walls together along transverse sealing areas at each side of the line of severance. To heat the material to a fusing temperature, the one sealing head has a chamber from which hot gas is directed onto one side of a sealing area, and the other sealing head has an electrical heater for applying a thermal impulse of heat to the other side of the sealing area. The hot gas presses the thermoplastic material against the electrical heater and provides a "free form" clamp for uniform sealing pressure.

Abstract: Slaughtered poultry, which has already been headwise introduced into a plastic bag member, is placed in a holder with a mouth of the plastic bag member being oriented upwardly. Two upper pivotal jaws are moved together to form a narrow cylinder about an upper end of the poultry, an overlying tubular member is forced down into a narrow cylinder for pressing the leg ends of the poultry downwardly, with the piston having a bottom closure which is active as a piston end but openable to enable a free bag mouth portion to be drawn into the tubular piston when vacuum is applied to the upper ends thereof. When the bottom closure is thereafter closed, the drawn up bag mouth portion will be clamped to the piston and the piston is rotated for twisting the bag mouth portion. Thereafter, the bag holder is moved past a tape applicator device for fixing of the twist bag mouth portion, with the bag portion outside of the tape being cut off and drawn away through the piston.

Abstract: An improved method of gluing a package in an in-line packaging machine. The package is of the type having a plurality of leading and trailing end flaps which are glued to be together during the packaging process. The novel method comprises in part providing at least two glue nozzles in the line of the packaging machine direction with one glue nozzle facing downwardly and upstream while the other glue nozzle faces downwardly and downstream so that the glue is applied to a pair of the end flaps by one nozzle in an upwardly direction and by the other nozzle in a downwardly direction as the package is moved through the packaging machine past the glue nozzles. Subsequently thereafter, the other pair of end flaps are turned inwardly and are held in position after being glued until the glue sets. The four flaps of the package are turned inwardly by a first and a second flap closing means.

The apparatus further comprises folding means for folding the tabs downwardly and pressure means for holding the tabs against the coupler to heat-seal the coupler and cover attachment together.

Abstract: In automatic preparation of flexible, disposable packing containers for materials such as eggs or fruits during intermittent transportation along a straight path of travel of each packing container, an opener cord is wound up and tied about the joint between receptacle and cover of the packing container while provisionally deforming, making use of the flexibility, the packing container so that the joint should assume an arcuate construction, and removal of deformation brings about tight winding-up of the joint so that pulling of the cord in a sealed packing container by users should enable easy opening of the packing container through breakage of the joint.

Abstract: A method for sterilizing packaging material, the packaging material being employed subsequent to its sterilization for the aseptic packaging of foodstuffs. The method includes the steps of (1) first subjecting the packaging material to ultrasonic vibrations through a liquid medium, and (2) then subjecting the packaging material to ultraviolet radiation. The bactericidal effect of steps (1) and (2) combined together as a sequence in the order recited is greater than if practiced in the reverse order. The process of this invention can be applied to a moving web of packaging material. The moving web, after its sterilization treatment, can be fed through known machinery for forming, filling, and sealing of aseptic packages for foodstuffs.

Abstract: Apparatus is disclosed for stacking a continuous paper form having uniformly positioned folds or seams as it exits from a device such as a printer. It utilizes a pair of curved surfaces over which an air flow is alternately directed to alternately create an air film over each of the curved surfaces. This air film attracts the paper in such a manner that the continuous paper form is refolded in a bin or stacker in its original configuration.
