High dynamic load capacity, chemical resistance and fatigue strength are properties that mean S-Ply® leaf springs also for paper production machines. S-Ply® leaf springs are used as trailing arms for pulp dewatering screens and as support springs for breast rolls. Depending on the design, standing and hanging screens and breast rolls are used. The springs are exposed to high humidity and have to transmit high mass forces with large deflections. Again, S-Ply® leaf springs have proven themselves in many years of use.
