SYSTEM AND METHOD FOR PRODUCING AN ARTICULATING BOARD PRODUCT HAVING A FACING WITH SCORE LINES IN REGISTER TO FLUTING

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. 1.

SYSTEM AND METHOD FOR PRODUCING AN ARTICULATING BOARD PRODUCT HAVING A FACING WITH SCORE LINES IN REGISTER TO FLUTING

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. 1.

SYSTEM AND METHOD FOR PRODUCING A FACING FOR A BOARD PRODUCT WITH STRATEGICALLY PLACED SCORES

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. 18-. (canceled)9. A board-making method , comprising:scoring a paper facing with a plurality of score lines at first intervals prior to combining the paper facing with any other paper product;embossing a paper medium with a plurality of flutes at second intervalscombining the paper facing with the embossed medium such that the score lines at first intervals are set with respect to the flutes at second intervals.10.
