A case erector may operate in multiple modes. In a slotted-case mode, the case erector may accept and erect slotted cases, while various plunger-case erection components are deactivated. In a plunger-case mode, the case erector may accept and erect plunger cases, while various slotted-case erection components are deactivated.

The present invention relates to a box forming machine for forming boxes of different shapes and sizes, comprising a forming station including an operating space, demarcated by upper and lower devices and receiving a box during the forming thereof, without horizontal movement of said box; flexible, pressurizable, and heatable glue conduits connected to a plurality of glue application nozzles, configured for being positioned in different positions consistent with the size of the box to be formed, and at least one electrically-operated valve configured for applying said hot glue in respective relative positions of said glue application nozzles with respect to the box, according to operative parameters associated with the dimensions of the box to be formed, including dimensions of upper and lower flaps of said box and at least one working temperature of a hot glue to be applied previously input in a user interface connected to a control device.

A foldable container moveable between a stowed configuration and a deployed configuration defining an interior area for holding bulk material is provided. The container includes opposed side panels and a bottom flap extending from a bottom edge of each side panel. A tab member extends from a distal end of each bottom flap and a tab finger extends from each tab member so as to define a hook at a distal end of each bottom flap. The hooks are interconnected so as to hingedly connect the distal ends of the bottom flaps together, thereby causing the bottom flaps to rotate between their respective stowed and deployed configuration positions as the end panels are translated between their respective stowed and deployed configuration positions. Legs are formed between the side and end panels to secure the container to a pallet and gap covers are formed to cover resultant gaps due to the formation of the legs.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

A can, and device and method for producing same, includes two circular end elements forming a base and lid. The can further includes a sleeve which has fold lines forming edges, the can sleeve having a circular cross-sectional area at both ends and a polygonal-sectional area in its central region. The polygonal cross-sectional area in the central region is at most decagonal.

A quality-control device (200) includes: an illumination system (202) for illuminating one peripheral face of each folding box, an image capture device (204) for forming a multiple image of the respective peripheral faces of a bundle of folding boxes, an image processing system (206) for: i) detecting within the multiple image each peripheral end of the slots of each box that separate its adjacent flaps, ii) generating a data set indicative of the geometry of each peripheral end, and iii) analyzing the data set to determine the width of each peripheral end.

A folder/gluer unit includes an upper transfer belt that transfers a corrugated sheet in a direction of transfer, a pair of forming belts that abut against a folding surface which is formed by folding both end portions of the corrugated sheet in a width direction orthogonal to the direction of transfer and fold both of the end portions of the corrugated sheet in the width direction, a pair of folding bars that are disposed in the direction of transfer, abut against the folding surface at both of the end portions of the folded corrugated sheet in the width direction, and guide both of the end portions of the corrugated sheet in the width direction, a moving mechanism that moves the pair of folding bars in the width direction and in a vertical direction, and a control unit that controls the moving mechanism to adjust a position of the folding bar.

A method for checking and correcting the position of a blank comprised of three flaps arranged in a row, the method including the following steps: closing the right- and left-hand flaps one above the other at least in an overlapping portion, gluing the flaps together; positional checking of the right-hand edge and the left-hand edge and comparing those edges with a predetermined position in order to determine a positional deviation of the flaps and, if the positional deviation exceeds an admissible deviation value, then before the glue sets, fixing the central flap at a location via the lower face of central flap using a fixing device using vacuum-induced negative pressing, then holding the upper face of the right-hand flap and of the left-hand flap by respectively at least one suction cup which applies vacuum, and correcting the position of the left-hand flap and/or of the right-hand flap by moving the suction cups sideways.

A foldable container moveable between a stowed configuration and a deployed configuration defining an interior area for holding bulk material is provided. The container includes opposed side panels and a bottom flap extending from a bottom edge of each side panel. A tab member extends from a distal end of each bottom flap and a tab finger extends from each tab member so as to define a hook at a distal end of each bottom flap. The hooks are interconnected so as to hingedly connect the distal ends of the bottom flaps together, thereby causing the bottom flaps to rotate between their respective stowed and deployed configuration positions as the end panels are translated between their respective stowed and deployed configuration positions. Locking tabs extending from distal ends of end flaps extend into the interior area of the container to secure the container in the deployed configuration.

A packaging box is disclosed, able to have smoothly curved wall portions. The box includes a perimeter wall defining a void thereby. The perimeter wall includes a first fold line and a second fold line. The first fold line and the second fold line may be parallel. A distance around the perimeter wall from the first fold line to the second fold line measured in a first plane perpendicular to the first and second fold lines in a first rotational sense is the same as a distance around the perimeter wall from the first fold line to the second fold line in the first plane in a second rotational sense opposite to the first rotational sense. When the first fold line is fully unfolded, the perimeter has a continuous surface including the first fold line. A tube, blank, method and machine for forming the box are also disclosed.
