A method for automatically closing an open packaging box with a cardboard lid, said box comprising a polygonal bottom panel defined by three or more bottom panel edges and sidewalls joined over respective crease lines to said bottom panel edges, each sidewall forming a substantially right angle with the bottom panel, said lid comprising a polygonal top panel defined by three or more top panel edges and corresponding to the bottom panel of the box to be closed and flaps joined over respective crease lines to said top panel edges and adapted for being folded onto a corresponding one of said sidewalls, the method comprising a step of folding each flap along the respective crease line partially towards a position, in which the flap forms a substantially right angle with said top panel and placing the lid above said box such that the top panel and the bottom panel are substantially aligned and such that, seen onto each sidewall, each flap overlaps one of the sidewalls, a step of releasing the lid allowing it to be guided by the partially folded flaps into a position on the box, in which the top panel and the bottom panel are aligned, and a step of folding each flap onto the respective sidewall fully into said position, in which the flap forms a substantially right angle with the top panel.

A system and method for a double glue joint is provided. The box is movable between knockdown and assembled configurations. In the knockdown configuration, the box includes a plurality of co-planar panels connected to one another, with a first and last panel each having a free end having a tab. One of these tabs, along with a portion of the panel adjoining the tab, are coated with adhesive. The box is movable to an assembled configuration by folding the panels relative to each other by one or more score lines until the free ends of the first and last panels meet. Utilizing the adhesive, the tab of the last panel is secured to an exterior surface of the first panel while the tab of the first panel is secured to an interior surface of the last panel, thus forming a double glue joint with interior and exterior connections.

A blank for constructing a crush-tolerant container includes a first side panel, a bottom panel, a second side panel, and a top panel coupled together in series. At least one cutout and at least one bridge portion are defined along a first fold line between the top panel and the first side panel. The at least one bridge portion and the at least one cutout are configured to maintain the top panel in a plane spaced above a top edge of the first side panel when the container is formed and the top panel is not under a stacking load, and to allow the top panel to move downwardly such that at least a portion of the top panel is substantially co-planar with the top edge of the first side panel when the container is formed and the top panel is under the stacking load.

A method of forming reinforced packages. The method can comprise moving a blank in a machine direction on a blank conveyor, and forming a tubular web while moving a first web of material and a second web of material in the machine direction. The forming the tubular web can comprise at least partially sealing at least a portion of the first web and the second web together to form a sealed margin of the tubular web. The method further can comprise forming a liner by cutting the tubular web, forming an attached blank by attaching the liner to the blank, and moving the attached blank in the machine direction on the blank conveyor.

A trap for certain insect pests may be configured to be particularly suitable for bedbugs and take the form of a foldable pitfall bedbug trap. The pitfall trap walls extend vertically upwardly at an angle and are sufficiently rough to permit bedbugs to climb to an upper edge of the trap, whereas the inner surfaces of the pitfall trap walls have been treated with a smooth material, such as being laminated, causing bedbugs at the upper edge to fall upon initiating contact with the inner pitfall walls and their smooth characteristics. The resultant foldable pitfall bedbug trap is relatively inexpensive to produce and easily user-deployable.

Apparatus for making a cardboard strip for packaging includes a store for a stack of cardboard sheets, a gripping mechanism for picking up a sheet from the stack and positioning another sheet on a first support for the application of adhesive, and a transfer mechanism for transferring the first sheet to rest on the second support with an end portion having the adhesive projecting towards the store and towards a third support. The third support is disposable in a raised position to raise an end portion of a second sheet coming from the store and in a lowered position to lower the end portion of the second sheet and position it at the end portion of the first sheet. A pressor presses the two superposed end portions of the two sheets to fix the end portions to one another to form a cardboard strip.

An improved mailer folding apparatus that forms mailers from mailer blanks. The mailer folding apparatus comprises a transport assembly and one or more folding assemblies. The transport assembly moves mailer blanks and/or mailers through the mailer folding apparatus. The one or more folding assemblies may each comprise a folding system and a carriage system. The folding system may selectively allow for the folding of a mailer blank into a mailer. A carriage of the carriage system may move the folding system longitudinally between different positions relative to the transport assembly. An engagement system separate from the carriage system or integrated into the carriage system may engage and disengage the folding system with the transport system for selectively feeding a mailer blank through the folding system, or disengage the folding system for allowing a mailer blank or folded mailer to bypass the folding system.

A measuring device for measuring a width (W) between a first edge (4) and a second edge (5) of spaced apart opposed edges (4, 5) of a slot (16) in a product (1′), comprising: a measuring part (18), with a measuring detector and a display (28), and provided with a first tab (37) configured to enter into the slot (16), and a slide (29), defining a longitudinal axis (X), being arranged so as to be adjustable relative to the measuring part (18) along the longitudinal axis (X), and provided with a second tab (46) being configured to enter into the slot (16).

The slide (29) is adjusted so that a first surface (44) of the first tab (37) contacts the first edge (4) and a second surface (49) of the second tab (46) contacts the second edge (5).

A distance (d) between the first surface (44) and the second surface (49) corresponding to the width (W) is detected by the measuring detector, and the value of the width (W) is displayed by the display (28).

The first and second tabs (37, 46) are oriented downwardly relative to the measuring part (18), perpendicular or transverse to the longitudinal axis (X) of the slide (29).

A slitter device includes an upper rotary shaft and a lower rotary shaft that are supported so as to be able to rotate. An upper slitter head that is supported by the upper rotary shaft so as to be able to rotate therewith. A lower slitter head that is supported by the lower rotary shaft so as to be able to rotate therewith and that is disposed on one side of the upper slitter head in the axial direction of the lower rotary shaft. An upper movement device that can move the upper slitter head in the axial direction of the upper rotary shaft. A lower movement device can move the lower slitter head in the axial direction of the lower rotary shaft. A control device that controls movement of the upper movement device and the lower movement device.

A carton blank feeding and shuttle machine includes a first driven belt supported by a first plurality of pulleys and a second driven belt supported by a second plurality of pulleys, a first rod attached to the first driven belt and a second rod attached to the second driven belt. Each of the rods extend across the first and second opposing sides. At least one controller controls motions of (a) the first driven belt and (b) the second driven belt, and a plucking head is supported by the first and second rods such that the first and second driven belts create common motion to move the plucking head along a transport path and relative motion to extend and retract the plucking head. A linkage assembly includes a plurality of links configured to move a plucking head along a shaft in response to movements of the first and second belts.
