Provided are a slotter head, a slotter device and a box making machine comprising a cutter holder which is in a disk shape and is rotationally supported, a first cutting blade which is mounted to an outer peripheral portion of the cutter holder, a moving holder which is supported by the cutter holder movably along the circumferential direction, a second cutting blade which is mounted to an outer peripheral portion of the moving holder, a first drive device which rotationally drives the cutter holder, and a second drive device which rotationally drives the moving holder.

A machine a mandrel assembly includes a mandrel having an external shape complimentary to an internal shape of at least a portion of a container, a first lift mechanism operatively coupled to a first servomechanism to wrap a first portion of a blank about the mandrel, a second lift mechanism operatively coupled to a second servomechanism to wrap a second portion of the blank about the mandrel, and a folding arm coupled to the first lift mechanism and operatively coupled to a third servomechanism. A control system is in communication with the first servomechanism, the second servomechanism, and the third servomechanism and is configured to transmit a signal to each of the servomechanisms to independently control movement of the first lift mechanism, the second lift mechanism, and the folding arm to wrap at least the first and second portions of the blank about the mandrel to form the container.

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 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—including providing air vents to allow trapped air to escape during the pre-sealing process—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 box formed from a plastic corrugated material with soft score lines is provided. The soft score lines are formed to enable the top flaps of the box to lay substantially flat against the outer surface of the box when folded to an open position.

A box forming machine includes a converter assembly, a fold assembly, and an attachment assembly. The converter assembly converts sheet material into a box template. The fold assembly engages a first end of the box template and moves the first end of the box template to a predetermined position. The attachment assembly engages a second end of the box template and moves the second end of the box template toward and into engagement with the first end of the box template to attach the first and second ends of the box template together.

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 corrugated paperboard box is provided in which when flaps are bent, a perforated line along which the flaps can be separated from the box is less likely to break. Such a corrugated paperboard box includes a peripheral wall and top flaps, and is formed, at the boundary area between the peripheral wall and the top flaps, with a groove-shaped reverse scoreline recessed on the side of an outer linerboard, and a pair of groove-shaped recesses recessed on the side of an inner linerboard, and extending in parallel to each other so as to sandwich the area in which the reverse scoreline extends. The corrugated paperboard box is further formed, in one of the groove-shaped recesses, with a perforated line along which the top flaps can be separated from the peripheral wall. The top flaps can be bent along the perforated line toward the inner surface of the peripheral wall.

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.
