The invention is directed to a balanced process for extrusion of a plastic corrugated sheet or blanks, and subsequent converting of the blanks into plastic boxes. The process includes conveying the blanks to a plurality of forming stations for incrementally forming features on the blank needed for forming a box. The present process is performed at a slower speed than typical paper corrugated forming.

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.

A sheet processor subjecting a sheet having been conveyed forward to processing along a direction perpendicular to a conveyance direction of the sheet, includes: a processing unit performing the processing; and a receiving unit receiving the processing unit therein in a state capable of perfecting the processing on the sheet, and the processing unit includes a first processing tool 4A and a second processing tool 4B disposed to vertically oppose each other with a conveyance surface of the sheet disposed therebetween, and the receiving unit includes at least one receiver that removably receives the first processing tool 4A and the second processing tool 4B in the state capable of performing the processing on the sheet, with arbitrarily selected one of the first processing tool 4A and the second processing tool 4B disposed above the conveyance surface, and with arbitrarily selected another of the first processing tool 4A and the second processing tool 4B disposed below the conveyance surface.

Methods and apparatus for manufacturing a molded fiber part include: immersing a wire mesh mold in a slurry bath comprising water and fiber particles; drawing a vacuum across the wire mesh mold to cause fiber particles to accumulate at the wire mesh mold surface yielding a molded fiber part; transferring the molded part from the slurry bath to a die press assembly; and drying and die cutting the molded part in the die press assembly.

A multi-sided container has more than four sides and foldable panels integrally arranged with respect to each other. A first panel and a second panel form a contiguity with a first fold line disposed therebetween. The first panel and a third panel form a contiguity with a second fold line disposed therebetween. The third panel is not parallel with and not orthogonal to the first panel. A first strength reinforcement feature includes a first slot having a first planar edge oriented orthogonal to the first panel and orthogonal to a z-axis, and a second planar edge oriented orthogonal to the second panel and parallel to the z-axis. The third panel includes a cut edge proximate the first fold line having a third planar edge oriented orthogonal to the third panel and orthogonal to the z-axis. The third planar edge is disposed in a same plane as the first planar edge.

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.

A multivariable perforated adjustable height box is provided with improved folding, bending, and separation of adjacent panels. The multivariable perforated adjustable height box may include a box, columns, rows, glue tabs, column scores, row scores, perforations, cuts, skips, and bundle breakers. Perforation patterns may be irregular, angled, shifted, or otherwise configured to increase usability, strength, and/or other aspects of the packaging. A method to produce a packaging device with improved folding, bending, and separation of adjacent panels using the multivariable perforated adjustable height box is also provided.

A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.

A perforation pattern for multivarible adjustable height box is provided with improved folding, bending, and separation of adjacent panels. The multivariable perforated adjustable height box may include a box, columns, rows, glue tabs, column scores, row scores, perforations, cuts, skips, and bundle breakers. Perforation patterns may be irregular, angled, shifted, or otherwise configured to increase usability, strength, and/or other aspects of the packaging. A method to produce a packaging device with improved folding, bending, and separation of adjacent panels using the multivariable perforated adjustable height box is also provided.

A system for generating rules inserted into at least one pattern board including: a controller configured to generate at least one shape diagram, the controller also configured to determine number and measurement of crease rules to be generated based on the at least one shape diagram; a cutting station configured to receive and cut a first crease rule into the number and measurement of the crease rules; and a sorter configured to receive the crease rules from the cutting station and sort the crease rules according to the measurement of the crease rules, wherein the sorted crease rules are inserted into each of the at least one pattern board along with a cutting rule shaped by each of at least one bender.
