A magnetizing device in a web processing machine for magnetizing a magnetisable area of a web of packaging material is disclosed. The magnetizing device comprises a first magnetic component having a north pole and a south pole, and a second magnetic component having a north pole and a south pole. Poles of a first and same polarity are arranged adjacent in an opposed relationship and poles of a second and the same polarity are arranged remote from each other.

The product efficiency of bags each with an end face part is increased. A panel webs is guided to be divided along a line of weakness of the panel web and to be folded along division edges of the panel web. This guiding of the first panel and temporary sealed sections cause a side gusset to be cut open along a line of weakness of the side gusset such that open surfaces are formed. After the forming of the open surfaces, an end face web is supplied to be superposed on folded parts of the panel web and the open surfaces of the side gusset.

At least one of a horn or an anvil includes protrusions that protrude from a facing surface thereof. Two panel parts and a gusset part folded and interposed between the panel parts are sandwiched and compressed by the horn and the anvil. Two portions of the gusset part are welded to each other by ultrasonic vibration of the horn during the sandwiching and compressing.

A device for making tobacco pouches from a film includes a first folding station for receiving the film and providing a bottom fold in the film; a buffer station for buffering a length of film having the bottom fold; a second folding station for receiving the film having the bottom fold from the buffer station and providing a first fold; a second fold and a third fold in the film for defining the block-bottom, the first fold and third fold having a same fold direction and the second fold being located between the first and third fold and having a counter fold direction, where the first folding station is provided upstream of the buffer station and the second folding station is provided downstream from the buffer station.

A bag has front and back face panels having upright longitudinally extending side edges and transversely extending upper and lower edges. First and second gusset panels each have transversely extending upper and lower edges and upright longitudinal outer edges connected to the longitudinal edges of the face panels. A reclosable fastener strip extends continuously and transversely along the first gusset panel and inward along each of the face panels from the first gusset panel along part of a transverse width of the face panels. Thus opening of the fastener and folding out of the first gusset panel forms a spout on the bag. A separate generally rectangular floor panel is joined at its outer edge by thermal welds to the lower edges of the face panels and of the gusset panels.

A flexible package is disclosed. The flexible package includes at least one shape memory closure provided at an access opening of the package. A method of forming and dispensing contents from a flexible package is also disclosed. Various shape memory closures can be bubble-shaped or dome-shaped and can be hollow fluid-filled, solid, and the like.

A bag making machine for manufacturing bags from an elongated film having print patterns repeatedly printed on one surface or two surfaces at a print pitch corresponding to a predetermined number of bags includes a processing unit configured to process the film for each length corresponding to the predetermined number of bags, a moving mechanism configured to move the processing unit, a shooting device, and an image processing device. The shooting device includes not less than one line sensor installed with a longitudinal direction of the line sensor extending along the widthwise direction of the film and obtains a linear image extending throughout a width of the film for each shooting operation. The image processing device sequentially receives the linear images from the shooting device and detects the actual length of the predetermined number of bags of the film based on an image extending throughout the width of the film.

A former shoulder (10) for a packing machine. The former shoulder (10) includes a former (12) having an external surface (13) over which strip bag material passes to be reconfigured into a tubular configuration. The bag material passes downwardly through a central opening (14) in the former shoulder (10). The former shoulder (10) includes a pair of pivoted guides (22, 23) that engage edge portions of the tubular bag material to form a fold (29) in the bag configuration (26) of the tubular bag material.

A packaging material web stock is provided. The packaging material web stock can include first and second plies overlaid and sealed to each other at a plurality of seals that include a plurality of transverse seals extending transversely across the plies, wherein a plurality of interior cavities are defined between the plies and the transverse seals, the first and second plies arranged in a web that includes a plurality of packaging units arranged longitudinally in a series along the web, wherein the first and second plies form walls of the packaging units, and at least some of the packaging units include at least one of the interior cavities, and an expansion material disposed in the interior cavities in an unexpanded configuration, wherein the expansion material is arranged within the inner cavities such that, when expanded to the expanded configuration, the expansion material is configured to provide cushioning in the walls.

A method for conveying a strip plastic film that can appropriately change the conveyance path for a strip plastic film continuously conveyed from an upstream side such as a raw film to a downstream side includes, when the strip plastic film conveyed from the upstream side is conveyed to the downstream side while being wound on the outer surface of a guide member in at least the central region in the width direction of the film, moving, rotating, or tilting the guide member that has the strip plastic film wound thereon via a base connected to the guide member to change the frictional resistance of the strip plastic film with respect to the guide member and the tension of the strip plastic film, thereby allowing the strip plastic film to slide along the outer surface of the guide member, and thus changing the conveyance path for the strip plastic film.
