Case Study: a paper manufacturer in southern China achieves improved winder stability and higher speed with Valmet's customized solution

a paper manufacturer in southern China boosts winder speed from 1900m/min to 2200m/min with Valmet

A paper manufacturer in southern China faced persistent operational issues with its aging rewinder, including unstable tension causing paper breaks, bottom folds, and reduced machine speed. After their own attempts to resolve the problems failed, they sought a solution from Valmet's on-site service team.

Valmet implemented a customized solution that involved replacing mechanical parts, recalibrating the unwinding station, and optimizing operating parameters. The project was completed in just three days, exceeding expectations. The results resolved the tension and quality issues and increased the machine's operational speed from 1900 m/min to 2200 m/min, significantly enhancing stability and efficiency for the customer.
