The present invention relates to systems and processes for cutting and creasing corrugated cardboards, and more specifically, to digital system and processes for cutting and creasing corrugated cardboards, wherein the system includes an array of cutting elements that can be dynamically configured to cut and/or crease a wide range of contours.

A creasing unit for creating fold lines in cardboard, comprising two crease rollers (110, 112), each crease roller having a circumferential protrusion (114, 116) adapted for indenting cardboard to create a fold line, wherein the crease rollers (110, 112) are rotatably mounted next to each other such that each crease roller (110, 112) can rotate about its own centre axis (122, 124) and each crease roller (110, 112) is movable between at least a first position for creating a fold line and a second position for either allowing cardboard to pass the respective crease roller (110, 112) without being indented by the respective crease roller or for creating an additional indented line being less deep than the fold line.

Methods, apparatus, and systems increase converting accuracy and consistency of corrugated articles of manufacture such as blanks, intermediates or converted structures to minimize unintended gap variations, fishtail variations and visual discord as well as to minimize unintentional loss of strength due to conversion of such articles. The constitution of converted articles formed from a corrugated board blanks according to the invention comprises at least one intelligently located score, slit or slot (hereinafter collectively “registered modification”) based upon knowledge of the corrugated board's fluted medium, including the absolute relative location of at least one fluted medium feature and/or the fluted medium geometry, such as its pitch.

A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.

A die and counter die system for impressing a relief pattern onto a substrate, including a male die film and at least one female die. The female die includes a female-die contact surface including at least one cavity defining the relief pattern. The male die film includes a flexible male-die contact surface which is featureless in a region thereof opposing the relief pattern on the at least one female die. The system further includes a compression mechanism adapted, when the substrate is disposed between the male die contact surface and the female die contact surface, to move the male die film and the at least one female die towards one another so as to impress the relief pattern on the substrate.
