Abstract
A system and method for inducing fluting in paper aligned in a machine direction of the paper while the paper is being fed through the board-making machine in the machine direction. In an embodiment, a method of producing the medium for a board product includes unwinding paper from a paper roll in a machine direction that is naturally aligned with the machine direction of the paper. Then, an embossing or scoring stage embosses or scores the paper with fluting that is also aligned with the machine direction of the paper. The resultant fluted paper has flutes that are aligned with underlying fibers of the paper, thereby taking advantage of the natural strength of the aligned fibers in the machine direction of the paper. Further, embossing or scoring paper for fluting greatly reduces take-up when such a fluted medium is compared to a facing that may be combined with the fluting to yield a board product. Further, maximum combined board strength is realized when all underlying fibers of all participating papers are aligned in MD and flute direction.
