A system and method of at least partially forming reinforced packages. The method comprises moving a construct in a machine direction on a construct conveyor. The construct conveyor can comprise a primary lug belt with a primary lug, the construct can be disposed on the primary lug belt, and the moving the construct can comprise moving the primary lug belt in the machine direction to push the construct in the machine direction. The method further can comprise positioning a liner on the construct conveyor so that the liner at least partially extends over the construct and moving the liner in the machine direction on a secondary lug belt of the construct conveyor. The secondary lug belt can comprise a secondary lug and the moving the liner can comprise moving the secondary lug belt in the machine direction to push the liner in the machine direction.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

A container blank (1), so sized and shaped as to form a shipping pack having front (2) and rear (3) walls to which there are attached, along respective fold lines (2a,2b,3a), side wall sections (11,12;16,17) each being foldable so that said front and rear walls are in juxtaposed alignment, wherein an interior open-mouthed bag (30) is adhered to the inner surfaces of the front and rear walls. When a shipping pack is erected from said container blank, the folded interior bag (30) is deployed to align with the inner volume of said erected pack so as to provide a lined open-mouthed container to be filled and subsequently sealed for dispatch. The shipping pack is configurable in a folded flat stackable form having an interior bag in situ for storage or dispatch and is easily machine assembled or manually formed into an open-mouthed shipping pack at point of use.

A method for forming a container using a machine includes extracting a blank from a magazine, transferring the blank in a blank transfer direction X, and positioning the blank on a deck. The method also includes translating a pick-up assembly from a first end to a second end along a horizontal direction Y perpendicular to the blank transfer direction X, the translating including transferring a web from a first location proximate the first end to a second location proximate the second end. The method further includes depositing, at the second location, the web into an at least partially overlying relationship with the blank to form a blank assembly, transferring the blank assembly along the deck in the blank transfer direction X while translating the pick-up assembly from the second end back to the first end, and wrapping the blank assembly around a mandrel to at least partially form the container.

A process for producing bags comprising: feeding a bottom web, a first side web and a second side web in a conversion process, each of the webs having a first side edge and a second side edge, wherein the first side edge of the first side web is aligned with the first side edge of the second side web, the second side edge of the first side web is aligned with the first side edge of the bottom web, and the second side edge of the second side web is aligned with the second side edge of the bottom web, thereby forming an inverted T-shaped web comprising a base having first and second wing portions and a riser, wherein the first wing portion comprises the bottom web and first side web, the second wing portion comprises the bottom web and the second side web, and the riser comprises the first and second side webs; sewing the first side web to the bottom layer in the first wing portion with a repeating pattern comprising a truncated triangle having a narrow portion and wider portion, and a tab separating the triangles, wherein the narrow portion of the triangle points toward the second side edge of the first side web; sewing the second side web to the bottom layer in the second wing portion with a repeating pattern comprising a truncated triangle having a narrow portion and wider portion, and a tab separating the triangles, wherein the narrow portion of the triangle points toward the second side edge of the second side web; contacting the first and second wing portions by folding them toward each other, thereby forming a folded web; rotating the folded web to the horizontal; sewing the first and second webs together in the riser with a repeating pattern comprising a flat-bottomed U shape with tabs separating the repeating U's, where the flat bottom of the U faces the first side edge of the first and second side webs, and the tabs separating the flat-bottomed U's are bisecting the tab separating the triangles in the first and second wing portions, thereby forming a web of sewn bags; cutting the web along the edge of sewn bags to remove the sewn portion corresponding to the flat bottom portion of the flat bottom U shape parallel to the edge, thereby forming a web of open top bags; and transversely cutting the web of open top bags at the middle of the truncated triangles and bisecting the repeating U's, thereby forming separate, open bags, and optionally scrap material.

A machine (1000) for forming a blank assembly having a blank and a retaining web coupled to the blank includes a deck (1250) coupled to a frame (1002), and a blank transfer assembly (1200) coupled to the frame. The blank transfer assembly is configured to position the blank on the deck. The machine also includes a web transfer assembly (1700) coupled to the frame. The web transfer assembly includes a pick-up assembly (1730) moveable between a first end and a second end of the web transfer assembly.
