Sudden One-Way Warp in Corrugated Board? Don’t Touch the Speed—Check These Three Things First
When corrugated board suddenly starts warping hard in one direction, adjusting line speed is almost always the wrong first move.
One-way warp is not a speed problem—it is a physical imbalance problem.
This article provides a practical 10-minute on-line decision checklist to help corrugator operators and process engineers quickly determine whether the root cause lies in paper moisture and temperature imbalance, uneven heat input, or tension and pressure mismatch.
By following a clear, step-by-step diagnosis order, you can avoid masking the real issue with ineffective speed changes, reduce scrap and downtime, and restore process stability through targeted, traceable adjustments.
