The main goals of the project were: paper quality improvement (Basis Weight CD profile, TSO profile and 2 sigma COV), as well as PM capacity increase.
PMP’s scope of delivery included a 4 channel Intelli-Jet V® (hydraulic head-box) for a top ply, a pressure pulsation attenuator system, a temperature control system and a wire rebuild (top ply mini-Fourdinier). The new hydraulic head-box assures significant improvement of basis weight profile, uniform paper web structure and significantly better formation. The temperature control system minimizes CD slice open deviations due to thermal, pressure and gravity forces, but also minimizes production loses. PMP was responsible also for a Vacuum System, on site erection and start-up supervision.
Main project achievements are: The TSO profile of top ply range increased significantly. The dry basis weight profile 2 sigma in cross machine direction (CD) was also improved. Top layer formation have been also improved.
Formation improvement can be seen in a much better top side smoothness. Final product formation has been improved as well. As a result of a better tuning allowed, operating machine speed increased as well.
