A blank of sheet material for forming a polygonal container is provided. The blank includes a bottom panel, two opposing side panels, two opposing end panels, and a reinforcing panel assembly extending from a first side edge of a first end panel of the two end panels. The reinforcing panel assembly includes a corner panel extending from the first side edge of the first end panel, a first reinforcing side panel extending from a side edge of the corner panel, a second reinforcing side panel extending from a side edge of the first reinforcing side panel, a reinforcing corner panel extending from a side edge of the second reinforcing side panel, and an inner end panel extending from a side edge of the reinforcing corner panel. The corner panel and the reinforcing corner panel are configured, upon articulation of the blank, to be positioned into face-to-face relationship to form a corner wall of the container extending from a side edge of an end wall of the container to an end edge of a side wall of the container.

A system is claimed for forming a container from a tubular blank comprising a plurality of panels and flaps interconnected to provide a generally flattened tubular configuration. A first and second panels are provided with the second panel being rotatable relative to the first panel. The system may comprise a first engagement device for engaging the first panel and a second engagement device for engaging the second panel, and being located on a panel rotating apparatus operable to rotate the second panel from an orientation generally parallel to the first panel to a second orientation at an angle to the first panel. The generally flattened tubular blank may be reconfigured from a generally flattened configuration to an open configuration.

A normalizing system for use with a case former, the system's components function and use are provided. Components of the system include a frame that defines a blank magazine area and a case forming area. Case pickers within the blank magazine area are configured to engage and lift a top-most case blank from the magazine. The pickers transfer the blank to left and right clamp assemblies, which grasp respective edges of the blank and then advance the blank toward the case forming area along a linear pathway. Alignment sensors positioned across the pathway detect if the case blank is in alignment as determined by the value of the angle(s) that the leading edge of the blank forms where it intersects each of the alignment sensors. If misalignment is detected, servos which control the rate of advancement of the clamp assemblies, adjust that rate to bring the blank back into alignment.

A machine for forming a container from a blank of sheet material includes a forming station and a compression station. The forming station is configured to form a reinforcing corner assembly from first and second reinforcing panels extending from an end panel of the blank. The compression station is configured to rotate side panels and end panels of the blank to be substantially perpendicular to a bottom panel of the blank. The compression station includes a plurality of plows at least partially defining a plunger opening, and a plunger vertically movable through the plunger opening. The plurality of plows are configured to rotate the side panels and the end panels towards the interior surface of the bottom panel.

A loading device to supply successively with cardboard sheets a station for handling the sheets by folding to form from them boxes for packaging, the handling station having a storage area to receive the successive sheets, optionally grouped in bundles, the device itself having a manipulator that includes: a gripping tool to pick up the sheets; an actuator to move the tool between an inventory of sheets and the receiving storage area of the station; a detection unit for detecting the status of filling of the storage area; and a control unit that directs the action of the device and that receives detection information from the detection unit to do this, the control unit being independent of the control of the handling station and programmable to adapt the operation of the loading device to the type of sheets handled. A corresponding process is also described.

A packaging box, cutouts, method and device for producing corrugated cardboard boxes comprising walls, a base (6) and a cover (7), the inner face of the base being provided with at least two recesses (33) and the cover comprising at least two tabs (38) adhered to the upper face thereof, directly above the recesses of complementary shape. The recesses and/or the tabs are situated fully inside the corresponding face or faces (31, 32).

Cartoning machine comprising a magazine configured to store stacks of cardboard dies (F) and means for picking up and transporting the dies (F) to move the dies (F) along a path (FM, FS) between the magazine, an unfolding station (S) and a product insertion station (N). The magazine comprises two mobile storage units (M1, M2) for storing the stacked dies, each mobile storage unit (M1, M2) being configured to store a respective stack (P1, P2) of dies (F). Cyclically, each mobile storage unit is in a waiting position while the other unit is in an operating position in which the means for picking up and transporting the dies are arranged and active. The storage units (M1, M2) are arranged one on a right side (DT) and one on a left side (ST) of the machine with respect to said path.
