Abstract
A cutting and/or creasing rule is produced on a 3D printing machine which may be mounted on a board for use is a die for cutting and/or creasing a sheet of paperboard or other material into a blank for a carton. With the advent of additive manufacturing, i.e. 3D printing, it is now possible to eliminate traditional slotted die boards with generally rectangular steel cutting and creasing rules and replace same with surface printed boards with three-dimensional creasing and cutting rules.
Claims27
A cutting/creasing rule for use on a die board for producing a carton blank in a sheet of blank material, the rule comprising:
- a proximal portion;
- a distal portion projecting from the proximal portion;
- and
- a tip on the distal portion which acts upon the sheet of blank material to form at least one of a cut and a crease in the sheet of blank material;
- wherein the distal portion has a cross-sectional configuration which is wider than the tip.
A die board for producing carton blanks comprising:
- a board substrate;
- a cutting/creasing rule, the rule comprising:
- (a) a proximal portion;
- (b) a distal portion projecting from the proximal portion;
- and
- (c) a tip on the distal portion which acts upon a sheet of blank material to form at least one of a cut and a crease in the sheet of blank material;
- wherein the distal portion has a cross-sectional configuration which is wider than the tip.
A method of producing a cutting/creasing rule for use on a die board for producing carton blanks, the method comprising the steps of:
- positioning a proximal portion of the rule;
- and
- 3D printing a distal portion and a tip of the rule on the proximal portion of the rule, wherein the distal portion has a cross-sectional configuration which is wider than the tip.
