Paper web vibration is a hidden mechanical defect affecting high-speed paper machine operation. When paper machine runs at high speed, unstable web tension, uneven transverse moisture, inconsistent surface friction and unbalanced internal stress will cause left-right swing and up-down vibration of wet and dry paper web. Continuous web vibration directly triggers uneven basis weight, transverse thickness deviation, micro wrinkles, periodic paper breakage and positioning deviation. It limits the maximum operating speed of paper machines, increases operation failure rate, causes batch quality deviation, and raises post-trimming waste. Most factories adjust roller balance and tension parameters mechanically, which can only relieve slight vibration, unable to eliminate internal stress induced fundamental vibration problems. Shandong Ludao Energy Technology Co., Ltd. provides professional paper web stabilization solutions. By balancing transverse-longitudinal internal stress, homogenizing whole-web moisture, and optimizing surface friction uniformity, we weaken web swing amplitude, restrain high-speed vibration, stabilize web running track. This technology lifts limit speed of paper machines, reduces periodic paper breakage, unifies transverse and longitudinal paper indicators, improves continuous operation efficiency, and lowers production defective rate.
