System and method for producing a multi-layered board having a medium with improved structure
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.
1. A board product, comprising:
a first paper medium having a machine direction aligned with a majority of underlying fibers and having a plurality of flutes aligned with the machine direction, wherein at least a set of the plurality of flutes each comprise a first linear leg support structure, a second linear leg support structure and a linear apex structure, wherein a first group of apex structures of the plurality of flutes comprise apex structures each having a respective elongated flat surface disposed in a first plane and a second group of apex structures of the plurality of flutes comprise apex structures each having a respective elongated flat surface disposed in a second plane that is different than the first plane;
a second paper medium having a plurality of sinusoidal flutes, the second paper medium coupled directly to at least some of the apex structures in the first group in the first paper medium; and
a paper facing coupled directly to at least some of the apex structures in the second group in the first paper medium.
2. The board product of claim 1 , further comprising a second facing affixed with respect to the second paper medium.
3. The board product of claim 1 , wherein the first linear leg structure and the second linear leg structure are affixed with respect to the paper facing at an angle between approximately 30 degrees and 60 degrees.
4. The board product of claim 1 , wherein each apex structure comprises a flat portion parallel to the paper facing.
5. The board product of claim 1 , wherein each apex structure further comprises a flat portion having a groove configured to channel an adhesive for coupling the at least some of the apex structures to the paper facing.
6. The board product of claim 1 , further comprising a continuous adhesive line coupled between each apex structure that is coupled to the paper facing.
7. The board product of claim 1 , wherein the first linear leg support structure comprises a first linear dimension that is equivalent to a respective linear dimension of the second linear leg support structure and the apex structure comprises a second linear dimension that is shorter than the first linear dimension.
8. The board product of claim 7 , wherein the first linear dimension is approximately ten times larger than the second linear dimension.
9. The board product of claim 7 , wherein the first linear dimension is approximately six times larger than the second linear dimension.
10. The board product of claim 7 , wherein the first linear dimension is substantially larger than the second linear dimension.
11. The board product of claim 1 , wherein the plurality of flutes comprise embossed flutes.
12. The board product of claim 1 , wherein the plurality of flutes comprise corrugated flutes.
13. The board product of claim 1 , wherein the plurality of flutes comprise scored flutes.
14. The board product of claim 1 , wherein the plurality of flutes in the first medium comprise a first major flute direction and the plurality of sinusoidal flutes in the second medium comprise a second major flutes direction, wherein the first major flute direction is perpendicular to the second major flute direction when the first medium is coupled to the second medium.
15. The board product of claim 1 , wherein the plurality of flutes in the first medium comprise a first major flute direction and the plurality of sinusoidal flutes in the second medium comprise a second major flutes direction, wherein the first major flute direction is not congruent with the second major flute direction when the first medium is coupled to the second medium.
