Applying padding material around shaped cutting blades includes: receiving a blade shape diagram and a rule of blade; bending the rule of blade according to the blade shape diagram to produce the shaped cutting blades; and applying the padding material around the shaped cutting blades using the blade shape diagram to produce a padded shaped cutting blade, wherein the padding material provides a spring action to quickly detach the shaped cutting blades from a plate matter.

A die-cutting scrap removal device for separating a product from an original plate is provided. The die-cutting scrap removal device includes a table-shaped removal main body part configured to stand upright on the ground surface; a first pressing-separation part fixed on the top surface of the removal main body part so as to move vertically; and a second pressing-separation part moving in the back and forth directions and the vertical direction on the top surface of the removal main body part, thereby readily separating scraps in mass quantities of products.

A rule to be inserted into a die-board that is pressed onto a plate matter, the rule including: a multi-edge cutting blade having a cutting blade edge, the cutting blade edge divided into multiple sections with multiple spacings between the multiple sections; and a plurality of connecting pieces configured to fit into the multiple spacings and to provide support for the multiple sections of the cutting blade edge when the rule is pressed onto the plate matter.

A machine for automatically manufacturing customized packaging items (I) from continuous laminar material, comprising at least one cutting and creasing unit (2) to form sheets (F) of laminar material with a plurality of cuttings and/or bendinglines (C), at least one variable-geometry forming unit (5) for forming the sheet (F) so cut and creased into a package (I) of predetermined dimensions, a multifunctional robotized manipulator (24) for automatically picking up one sheet (F) at a time from the cutting and creasing unit (2) and feeding the forming unit (5), the manipulator (24) being designed to automatically adapt to the predetermined dimensions of the packaging (I) on the forming unit (5) and interact therewith to form the packaging (I).

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.

A cutting tool structure, a manufacturing apparatus thereof, and a laminated structure for making a heat-retaining container are proposed. The cutting tool includes: a body; a blade portion extending in a lengthwise direction from the body; and a suppressing portion provided on one side of the body where the blade portion is formed for suppressing the foamed material. The cutting tool structure allows lamination of a foamed sheet and a paper substrate while forming a tear line on the foamed sheet to simplify the manufacturing process of the laminated structure for making a heat-retaining container.

A method of forming a packaging blank includes stripping away a portion of a stock material to create an offset void (24, 25) and blanking the stock material into a plurality of packaging blanks. Blanking includes separating the stock material along a plurality of severance lines (26, 28, 29) dividing between the blanks (100), wherein at least two of the severance lines are separated from one another by the offset void. Blanking can include separating the stock material along a plurality of severance lines dividing the blanks from one another by a blanking grid, wherein the blanking grid is arranged in a nested sheet-fed layout.

A packaging structure for at least one article includes a pair of generally rectangular support structures with front, side, rear, and interior walls. The walls divide the rectangular support structure into a plurality of triangular sections. The front and interior walls contain a least one opening configured to correspond with the configuration of the article to hold and secure the article in place. The packaging structure is created from a rectangular blank made of foldable material that has a plurality of spaced vertical fold lines, panels, and aligned openings each configured to correspond with the configuration of the article. The packaging structure is formed by folding the blank along the fold lines and securing the blank in the folded condition. The blanks are formed first within computer aided design software by determining the dimensions and profile of a packaging structure, forming openings for an article in a packaging structure, unfolding the packaging structure within the design software into a flat pattern to form a master blank, and using the master blank to create cutting dies for forming additional blanks.

The present invention provides a carton (100) made of paperboard having flaps (101, 105), the carton (100) comprising, at least one score (102) along a crease line (103) of at least one flap (101, 105), wherein the score (102) is 25% to 85% of thickness of the paperboard and 5% to 70% of length of the crease line (103). The invention also provides a method of securing flaps (101, 105) of the carton (100).

A presser assembly is provided for supporting a carton blank. The presser assembly includes a housing having a cavity formed therein. A presser plunger is telescopically received in the housing. The presser plunger is slidable between a first retracted position wherein the presser plunger is at least substantially received with the cavity in the housing and an extended position wherein the presser plunger projects from the open end of the housing. A magnetic biasing structure urges the presser plunger toward the extended position.
