Patent ID: 7455006

Claim:
A modular/configurable rotary die for a rotary die cutter for making a corrugated carton blank, from which a carton having at least one quick closing continuous closure panel can be erected, from a stock sheet of corrugated material, the rotary die comprising: a plurality of at least five interlocking modular die components which are capable of being combined in multiple configurations for producing multiple carton sizes, said die components being mountable directly on a roller of a rotary die cutter, the roller having a threaded hole pattern, where the die components are interlocked with one another, each die component having at least one blade thereon for at least one of scoring, creasing and cutting a corrugated sheet to cooperatively form a corrugated carton blank in a rotary die cutter from a stock sheet of corrugated material, a plurality of adjustable die mounting clamps having means for securing the die components anywhere on the roller of the rotary die cutter regardless of the threaded hole pattern, wherein said plurality of die components include, with reference to the three dimensions of the carton to be erected from the corrugated carton blank, at least one length die component which determines the length of the carton, at least one height die component which determines the height of the carton, and at least two closure panel die components which determine the width of the carton and produce respective fold-in panels of said at least one quick closing continuous closure panel, wherein each of said closure panel die components includes: two slit/cut blades each arranged for slitting a 45 degree angled line on a fold-in panel of a quick closing continuous closure panel, two perforation blades each arranged to cut and score the corrugated stock sheet to form a perforated straight line that is perpendicular to the length of the carton blank, and one scoring blade arranged to score a straight line at the bottom of the fold-in panel, parallel to the length of the carton blank and between the two perforated lines formed by said two perforation blades.
