Abstract: A machine or machine section for squaring folded container blanks has a conveyor for conveying slotted and partially folded container blanks. A folding device completes folding of each container blank while being conveyed by the conveyor. A gauge plate is inserted in a slot in each of the slotted and partially folded container blanks. A mechanism moves the gauge plate in timed sequence with the conveyor, inserts the gauge plate in the slot before completion of folding of the respective blank in order to "square" the folded blank, and then withdraws the gauge plate from the slot. Overlapping flaps of each folded blank may be tacked together during "squaring" by drops of hot melt adhesive which subsequently hold the flat folded blanks square while the conventional slow drying water soluble glue dries. The "squaring" arrangement may be incorporated in a conventional gluer/folder machine.
