A paperboard blank stacker assembly for supplying a stack of paperboard blanks to a container forming machine includes a stacker. The stacker has multiple blank stops arranged to hold a peripheral edge of a bottom blank of the stack of paperboard blanks, with the multiple blank stops defining an interior region. A blank carrier has at least one suction device moveable into a grasp position, where the suction device applies a suction force to the bottom blank, and a removal position, where the suction device is moved to remove the bottom blank from the stack of paperboard blanks by pulling the bottom blank through the interior region.

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 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 method of processing a blank for forming a construct includes obtaining the blank, the blank including a flexible material and is for being formed into a construct. The method also includes moving the blank in a downstream direction on a first guide and a second guide, and pressing an interior region of the blank with a shaping apparatus in a direction transverse to the machine direction as the blank moves in the downstream direction and as a peripheral region of the blank is engaged by at least one shaping bracket.

A method of forming a tray includes obtaining a blank, positioning the blank in a blank feeder assembly of a system for forming a tray, moving the blank from the blank feeder assembly to a nipping assembly, and moving the blank to a tray forming assembly, the tray forming assembly including a tray forming apparatus. The method further includes positioning the blank between a first tray forming portion of the tray forming apparatus and a second tray forming portion of the tray forming apparatus, the first tray forming portion includes a forming block that defines an interior, and the second tray forming portion includes a tray forming member, and driving the forming block into engagement with the blank and the tray forming member such that the blank and the tray forming member are at least partially received in the interior of the forming block to form a tray.
