The present invention relates to a blowing device (1) for blowing gas through a gas-permeable tubular-shaped packaging material (29). The blowing device comprises at least one gas nozzle (19; 75, 77), adapted to blow gas from an outside of the tubular-shaped packaging material through the tubular-shaped packaging material, and a guiding member (3), which comprises a web passage (5) having a surface (7) adapted to face the tubular-shaped packaging material, such that the web passage surrounds or substantially surrounds the tubular-shaped packaging material. The present invention further relates to a use of the blowing device, to a sealing arrangement (27, 71) for transversely sealing a gas-permeable tubular-shaped packaging material (29) and to an arrangement (37) for manufacturing of pouched products (39), which arrangement comprises such a sealing arrangement. The present invention also relates to a method for transversely sealing a gas-permeable tubular-shaped packaging material and to a method for manu facturing a pouched product, e.g. a portion-packed pouched oral snuff product.

A vertical form fill and seal system supports a sheet of material having material segments and a tube sized for drawing edges of the elongated sheet of material together in an overlapping configuration to form the sheet into a substantially tube shape. The VFFS also includes a sealer that seals the edges of the material to one another and a gusseting mechanism sized for forming a gusseted tuck in each of a left panel portion of the material and a right panel portion of the material. A cutting mechanism removes a first portion and a second portion of a first segment of the material segments in order to form a first cut and a second cut in the first segment and a sealing mechanism folds and seals the first segment at the first cut and at the second cut to provide an end wall with a substantially flat, rectangular-shaped footprint.

There is described a machine for packaging products in tubular wrappings of thermoplastic material obtained from continuous film unwound from a reel, equipped with a double transverse heat-sealing and intermediate cutting assembly that, with a horizontal translation movement, accompanies the pack that the assembly is closing the trailing end of to be unloaded while it is simultaneously closing the leading end of the tubular wrapper of the future pack that the heat-sealing and cutting assembly, also due to the presence thereon of pressers and counter-pressers, extracts from a tube-forming and longitudinal heat-sealing mandrel and that, by the same assembly, is separated from the pack upstream with a transverse cut.

At the end of its active movement, the transverse heat-sealing and cutting assembly opens and with a horizontal movement in the opposite direction to and at a higher speed than the preceding one returns to the cycle start position, upstream of a new pack already filled and ready to be heat sealed at the trailing end and accompanied to be unloaded, repeating the cycle described. The transverse heat-sealing and cutting assembly is aided by a conveyor that supports and advances the packs being formed and those finished and separated, and that is equipped with a gap with variable geometry, which opens during the active horizontal movement of the same assembly and closes during the reverse horizontal movement of the same assembly.

An exemplary embodiment of a cold seal package forming device (100) is provided, which may have a scoring device configured to score a continuous film laminate, the film laminate comprising a layer of pressure sensitive adhesive/PSA (36) disposed between a first film layer (37) and a second film layer (38); a stripping device configured to strip at least a portion of the second film layer (38) to expose the PSA (36); a forming device configured to form the film laminate into a package (30) having an interior; a feeding device configured to feed a product into the package interior; a sealing device (108, 142) configured to seal the product within the package interior via adherence of the exposed PSA (36) on a portion of a package periphery; and a separating device configured to singulate the package (30) from a continuous web of the film laminate.

A vertical bag-making/filling/packaging machine (1) includes: a top folding portion (20) which forms a first fold (F1) by folding a side of a band-shaped film (F) into a Z-shape; a bottom folding portion (30) which forms a second fold (F5) by folding a center of the film (F) into an M-shape; a top seal portion (40) which forms a top gusset (G3) and a spout portion (G7) protruding from the top gusset (G3) by heat-welding the first fold (F1) and side edges (E1 and E2) of the film (F) so as to make the film (F) into a tube shape; and a bottom-seal portion (50) which forms a bottom gusset (G4) by heat-welding the second fold (F5).

An opening apparatus for a gusseted tube which is fed in from a tube supply for the purpose of the later transfer to a device. The opening apparatus has at least two suction cheek arranged on each of two sides of the gusseted tube. Each suction cheek is arranged on one side of the gusseted tube and has a contact region which interacts with the gusseted tube and has a suction region with a protective device which lets an air flow through. The two suction cheeks lie opposite one another to be moved apart in a direction orthogonally with respect to the folded-together gusseted tube. An opening apparatus has both side cheeks of a pair arranged such that they can be moved along the outer face of the gusseted tube away from the other pair of suction cheeks to the outside.

An exchangeable ultrasonic welding module contains an ultrasonic transducer assembly (4) with a horn (5) and an anvil (7). The module contains a member (1) provided with a guideway (8) in a mating guideway (18) on the frame (10) of a filling tube (14). A locking element (11) secures the member (1) and the frame (10) in a fixed position relative to each other.

The member (1) is provided with an element (2) for linear motion of a sliding carriage (3) and an adjustable stop (6) for restricting the carriage movement (3). The ultrasonic transducer assembly (4) is firmly affixed to the carriage (3), whereas the anvil (7) is affixed to the member (1). The frame (10) may contain an adjustable stop (9) for locking the member (1) in a defined position as the member is inserted into the mating guideway (18).

A packaging machine and apparatus for forming and filling plastic bags for containing dry food products such as cereals or the like. The invention comprising a product dispensing port over which a film enveloping the port may pass and an inner passage through which a product may be dispensed. The dispensing port comprises a pair of opposing flaps pivotally coupled to the outlet of the dispensing port which are movable between an open and a closed position.

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.
