A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.

A plurality of pouch containers are continuously manufactured from materials including: a plurality of separate-type tubular film members each including a portion to be formed as a barrel portion; and a single first belt-shaped film member and a single second belt-shaped film member each including a plurality of portions each to be formed as a gusset portion. The step of closing an opening end of each of the separate-type tubular film members includes: supplying the belt-shaped film member to the opening end by conveying the belt-shaped film member in parallel with the separate-type tubular film members at the same speed as a conveyance speed of the separate-type tubular film members, to cause the belt-shaped film member to overlap with an opened joining margin of each of the separate-type tubular film members; and joining the joining margin to a portion of the belt-shaped film member that overlaps with the joining margin.

In one example, a plastic product such as a plastic bag includes one or more seals. One of the seals includes respective portions of first and second plastic films that are arranged one on top of the other. The respective portions are joined together and are aligned generally parallel to a direction of elongation associated with the plastic films, where the direction of elongation is a direction in which the plastic films elongate when under load. As well, the respective portions extend along a length of the joined plastic films and have a length that is greater than a length of the plastic films.

A female belt-shaped base is attached to a bag body at a region from a female hook to a first end near an open end of the bag body and to a second end near a housing space. A male belt-shaped base is attached to the bag body only in a bonding region without being attached at a region from a position where an engagement portion is continuously attached to a first end near the open end of the bag body.

Paper converting plant including a rewinder adapted to produce paper logs and having an inlet for feeding a paper web, a winding station where the logs are formed and an exit station for unloading the finished logs. The rewinder has walls delimiting a chamber inside which the logs are formed, and an air suction channel at a lower part of chamber. The suction channel exerts a suction causing the formation of an air flow directed from the top to the bottom inside the chamber. The chamber includes two semi-chambers communicating with the air suction channel such that a vertical air flow directed downwards is generated in each of them, the chamber being provided with a manner for regulating the vertical air flows providing vertically oriented identical air flow rates in the semi-chambers.

A bag-making and packaging apparatus includes a bag-making and packaging unit, a film feeding unit, a splicing device, and a control unit. The control unit allows a bag-making operation to continue by utilizing an auto-feeding function that feeds to the bag-making and packaging unit a film F spliced by the splicing device to take the place of a film F currently being fed to the bag-making and packaging unit. When the control unit judges that at least one of the film feeding unit and the splicing device is malfunctioning in a case where the control unit is utilizing the auto-feeding function, the control unit stops the auto-feeding function and executes a non-auto-feeding mode. The non-auto-feeding mode allows the bag-making operation to be continued by the bag-making and packaging unit and a film roll holding unit that is operable among plural film roll holding units.

A resealable front panel enclosure and method of manufacturing the same is provided that includes cutting or punching a tab in an unfolded film material and applying a zipper assembly to the film material. The film material is formed into a resealable enclosure by folding the film material subsequent to applying the zipper assembly to the film material. The tab is disposed on an exterior surface of a first side of the formed resealable enclosure, and the zipper assembly is disposed on an interior surface of the first side of the formed resealable enclosure.
