Abstract: 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 impressed (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are impressed 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 folded. A lack of precision in folding a board product leads to gap variation and fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when folded.
Abstract: A system and method for producing a board product made from paper products that have embossed medium that features an improved structural profile. The improved structural profile may include a triangular flute pattern wherein each flute may exhibit a first linear leg support and a second linear leg support that each support a center apex structure. The apex may have a substantially flat portion that is configured to engage a facing. As such, the board product may further include one or more facings that are adhesively coupled to the embossed medium. Further, the apex of each “triangle” may also have a groove or channel for receiving an adhesive in a continuous and uniform manner.
Abstract: Methods and apparatus for making scored mediums, particularly but not exclusively for use in the corrugated board arts, and articles of manufacture and compositions made there with and made there by. When at least one scored medium is used in a layered or laminated article, and particularly when selectively used as a liner member and/or fluted member in a corrugated board, whether as part of a corrugated board article of manufacture or a laminate with at least one other member, the article will possess mechanical qualities superior to those that would otherwise exist if a non-scored medium was/were used. To achieve these desired qualities, a major axis of the scores formed in the scored medium runs askew, and preferably perpendicular, to the direction of beam strength in any article or article intermediate to which the scored medium is to be associated.
Abstract: 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.
