The cartoner has been designed to form cartons from blanks, whereby the formed cartons have tapered concave sides. A unique series of elements, including capture lugs which hold and “bow” the carton blank, together with plow rods and oscillators which have curved metal plates are used to “pre-break” the score lines of the blank. Travelling pressure blocks having convex outer surfaces are used to press the concave sides of the carton while hot glue dries, whereby the unique, tapered cartons are properly formed.

A score breaking mechanism comprises a vertically reciprocable carriage having a pair of roof panel wings and a pair of gable panel wings mounted thereon. As the carriage is lowered toward a carton having score lines to be broken, two racks slidably mounted in the carriage contact stops, and upon continued downward movement of the carriage the racks rotate a pair of pinion gears attached to the gable panel wings to rotate the wings inwardly toward each other and into folding contact with the gable panels of the carton. When the downward movement of the carriage ceases, the roof panel wings are rotated inwardly toward each other over the enfolded gable panels to complete the score breaking operation. The roof panel wings are then rotated away from the carton before the carriage starts its upward movement, after which the gable panel wings are rotated away from the carton to clear the carton.

A box erecting machine includes a transport mechanism that can move an un-erected box from an entry portion of the box erecting machine to a forward portion of the box erecting machine. The transport mechanism can include pivot arm(s) and clamp(s) for securing and moving the un-erected box. The machine can also include a box erecting assembly that erects the un-erected box. The box erecting assembly can include an opening or unfolding mechanism that opens or unfolds the un-erected box into a generally rectangular tube. The machine can also include a folding mechanism and a closure mechanism for folding and securing the bottom flaps of the box.

Shown and described is an apparatus for the pre-folding of packaging sleeves including: at least one folding device with folding tools for pre-folding the bottom surfaces of a packaging sleeve and at least one folding device with folding tools for pre-folding the gable surfaces of a packaging sleeve. In order to achieve a precise and rapid pre-folding of the gable surfaces of a packaging sleeve on a compact system, it is proposed that all the folding devices are mounted movably in the vertical and in the horizontal direction. In addition, a method for the pre-folding of packaging sleeves is shown and described.

A method for assembling a blank including accessing a blank having a main panel portion and at least one flap portion coupled to the main panel portion. The method further includes positioning a plate adjacent to the blank, the plate having a curved edge, folding the flap portion relative to the main panel portion about the curved edge of the plate such that the flap portion is coupled to the main panel portion along a curved line thereof.
