A bag-making and packaging machine packages, in bags made from a film, articles discharged and dropped from an article discharge apparatus. The bag-making and packaging machine has a transverse sealing mechanism, a receiving member, a vertical moving mechanism, and a control unit. The transverse sealing mechanism transversely seals a film tube. The receiving member contacts an outer surface of the film tube above the transverse sealing mechanism and receives the articles A that drop through the inside of the film tube. The vertical moving mechanism moves the transverse sealing mechanism and the receiving member in the up and down direction. The control unit switches between a first mode and a second mode. In the second mode, the receiving member contacts the outer surface of the film tube at a lower height position than in the first mode.

A working process of a machine for wrapping products in packages, carried out with a thermoplastic material film from a reel, comprising: a loading station for the products to be packaged; a hollow mandrel with a relative forming shoulder; a sealing device for forming a seal of the longitudinal edges of the film; a horizontally mobile pusher for pushing a bundle of products from the loading station through the mandrel; a sealing and transversal cutting assembly formed by two vertically mobile elements mounted on a horizontally mobile primary carriage a conveyor a secondary carriage carried by the primary carriage; comprising the following operating steps: reducing the transversal section of the mandrel to a diameter smaller than the diameter of the bundle of products positioning the sealing device in a position for sealing the overlapped longitudinal edges of the film while forming a new tubular film casing; arranging the elements of the assembly in a closure position on the head portion of the new tubular film casing and on the tail portion of the tubular film casing of a finished package; and conveying of said new tubular film casing, by the movement of the primary carriage away from the mandrel, and repeating the preceding steps, so that the product placed inside the tubular casing by the mandrel is wrapped in a tight adherent manner due to the elastic retraction of the film of tubular casing.

A sterilizer-filler nozzle assembly for an aseptic packaging machine comprises a form section 40, a product supply duct that has a product outlet portion 4 which lies downstream of a distal end of the form section 40, a sterilization medium supply duct that has a sterilization medium outlet portion 16 which lies between the distal end of the form section 40 and the product outlet portion 4, and an exhaust duct that has an exhaust inlet portion 22 which lies between the distal end of the form section 40 and the product outlet portion 4. A gas supply duct is provided that has a gas outlet portion 10 which lies between the sterilization medium outlet portion 16 and the product outlet portion 4.

This invention discloses a process for forming a pouch having an evacuated headspace containing a flowable material. The process relates to optimizing both, the evacuation of the headspace in the pouch and the accuracy of the flowable material filled in the pouch. Specifically, the present invention employs a process that includes a multiple-step or a continuous compression of the pouch headspace to accomplish the goals. Also disclosed is a vertical form-fill-seal apparatus for forming a pouch containing a flowable material and having an evacuated headspace.

A device for sealing and cutting a film in a packaging apparatus, a packaging apparatus including the device, and a process using the device are provided. The device includes first and second members, one or both of which are movable with respect to the other. One of the members includes an elongated blade, and one of the members includes a cutting means positionable in a plurality of positions. The process includes creating a first seal on a tubular film, thereby creating a semi-sealed package, creating a second seal on the semi-sealed package, thereby creating a sealed package, creating a substantially transversal cut in the tubular film, thereby separating the semi-sealed package from a subsequent portion of the tubular film, and creating an incision in a section of the first or second seal, the incision defining a pre-determined breaking zone in the tubular film of the sealed package.

A packaging apparatus for small piece goods, the use of the packaging apparatus, and a method for producing a blister tube are provided. The packaging apparatus includes a packaging material guiding device for providing a shaped packaging material web suitable for receiving small piece goods, a longitudinal joining device which is arranged downstream of the packaging material guiding device and a transverse joining device which is arranged downstream of the packaging material guiding device. The transverse joining device joins the shaped packaging material web together at predetermined intervals transversely to the direction of travel to form a transverse joining area. The transverse joining device includes two joiners, a first joiner having a plurality of embossers that are individually movable transversely to the direction of travel and are arranged so that they can be extended from the first joiner and retracted into the first joiner.
