The invention relates to a transverse-sealing unit (09) for producing transverse-sealing seams in a tubular-bag machine (01), the transverse-sealing unit (09) comprising at least one sealing bar (11) which comes into sealing contact with at least one effective area when transversely sealing the film tube (05), and the transverse-sealing unit (09) comprising a support element (12) in which the sealing bar (11) is fastened, and the sealing bar having at least two effective-area sections (13, 14, 15), and the first effective-area section (15) protruding slightly over the second effective-area section (13, 14). The sealing bar (11) is mounted so as to be displaceable on the support element (12) in the direction of its longitudinal axis.

A support shaft capable of supporting a wound body with a long sheet wound therearound includes a first projection located at a proximal end of an outer peripheral part, and a second projection located at a distal end of the outer peripheral part. A core body of the wound body includes a one-end-side first recess part located at one end of an inner peripheral part, an other-end-side firsts recess part located at an other end of the inner peripheral part, and a second recess part located to extend from the one end to the other end. In a state where the core body is mounted on an outer periphery of the support shaft, the first projection engages the one-end-side first recess part or the other-end-side first recess part. When the core body is mounted to the outer periphery of the support shaft, the second projection engages the second recess to allow the circumferential position of the first projection to be aligned with the circumferential position of the one-end-side first recess part or the other-end-side first recess part around a central axis.

A sealing device for forming a transversal seal to a tetrahedral packaging container is provided. The sealing device comprises a sealing element and an imprint ruler arranged at a longitudinal distance from the sealing element. The sealing element is configured to provide a top transversal seal to a packaging container while the imprint ruler is configured to provide a transversal imprint to the same packaging container.

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).

Container filling systems are described herein. A container filling system includes a container assembly, a nozzle, a first roller and a second roller. The container assembly includes a plurality of containers, each having a container volume and a fluid manifold defining a fluid pathway, wherein the fluid pathway is in fluid communication with the container volume of each of the plurality of containers. The nozzle is in fluid communication with the fluid pathway, wherein the nozzle directs flow from a fluid source into the fluid pathway. The nozzle separates the fluid manifold into a first portion and a second portion to permit the fluid manifold to advance relative to the nozzle.

According to one embodiment a packaging method is provided in which a film is fed to a vertical forming tube, whereby the film is formed into a tubular shape, the ends of the tubular-shaped film are longitudinally sealed to one another by applying pressure on said ends, the product to be packaged is introduced into the forming tube and the film formed downstream of the forming tube is transversely sealed and cut. Furthermore, in the method, the ends of the film are pressed to one another with a force that keeps both ends static, the drop of the product upstream of the transverse seal is stopped or limited, and by maintaining said pressure and said stop or limitation, an airflow is generated inside the forming tube.

A control apparatus for controlling a packaging machine that includes a conveyance mechanism for conveying an item to be packaged includes: an acquirer configured to acquire a detection result from a sensor for detecting an item to be packaged; a determiner configured to obtain elapsed time from a predetermined time point until when the item to be packaged is detected by the sensor, based on the detection result acquired by the acquirer, and determine a shift direction in which the item to be packaged is shifted from a predetermined position, based on the elapsed time; and a controller configured to control, for the item to be packaged for which detection is performed by the sensor, implementation of any one of downstream units that are downstream of a unit in which the detection is performed by the sensor, based on the shift direction that is determined by the determiner.

The present invention relates to a sealing device (1, 101, 201) for sealing a packaging material (7, 107) enclosing a filling material (29) to provide portion-packed oral pouched snuff products (43). The sealing device comprises an anvil (3, 103, 203) with a first operation surface (11, 111, 211) and a sonotrode (5, 105, 205) with a second operation surface (13, 113), the anvil and the sonotrode being arranged to allow passage of the packaging material therebetween, the second operation surface being located opposite the first operation surface during operation of the sealing device. The first and second operation surfaces are arranged to weld a first portion (7a, 107a) of the packaging material to a second portion (7b, 107b) of the packaging material. At least one of the first or second operation surfaces comprises a first welding surface (11a, 111a) defining a first extension plane and a second welding surface (11b, 111b) defining a second extension plane, which has a different orientation than the first extension plane. The first and second welding surfaces are partly delimited by a cutting edge (15, 115, 215) having an extension direction along the first and second welding surfaces, such that the cutting edge separates the first welding surface from the second welding surface. The present invention further relates to an arrangement (19) for manufacturing of portion-packed oral pouched snuff products, which arrangement comprises such a sealing device. The present invention also relates to a method for portion-packing of an oral pouched snuff product.

Provided is a device (400) for forming a pouch. The device can include a first sealing section (404) having a curved heat-transfer surface, and a second sealing section (406). The second sealing section (406) can include a first heat-transfer surface (407), a second heat-transfer surface (405), and a heated cutter (408). The heated cutter (408) can be disposed between the first heat-transfer surface (407) and the second heat-transfer surface (405). The device can also include an optional cutting face that accepts the heated cutter.

A packaging apparatus (e.g., otherwise described as a mailer apparatus with a material feeder assembly, a product supply assembly, a folding assembly, a sealing assembly, and/or a packaging apparatus system (e.g., including a controller thereof) for controlling the operation of the packaging apparatus. The packaging apparatus is configured for delivering products and material at the same time, and forming a package (e.g., a mailer, or other package) directly around the products. A material feeder assembly of the packaging apparatus supplies material for packaging and a folding assembly receives the plurality of products and folds the material around the products. The sealing assembly seals the material around the at least one product to form packages (e.g., makes a longitudinal seam, forms a transverse seam, and/or separates the material at the transverse seam).
