After machining with a medium-high roller, the grinding head cam setting is set to achieve a specific medium-high shape.
Shrinkage
After the paper is formed, from the perspective of the group fibers, it is worthwhile that the longitudinal fibers flow in the longitudinal direction of the paper machine, the pulling force is large, and shrinkage does not occur easily. The transverse fibers of the paper are intertwined with each other, cancel each other out and have some shrinkage. Paper's vertical multi-layer fibers shrink more. Therefore, this effect causes changes in thickness and tightness.
