Corrugated Line Tension Control & Web Break Handling: Stable Paper, Stable Output

In corrugated board production, unstable paper tension causes drift, wrinkling, and frequent web breaks—directly hurting output and quality. Tension control and web-break handling are key to stable production.

The Scenario: Three Problems from Unstable Tension

Poor tension control brings three problems:

Pain Points

• Paper drift and wrinkling hurt board flatness and bonding;
• Frequent web breaks force stops for splicing, causing heavy loss and low efficiency;
• Tension fluctuation makes board dimensions unstable, raising scrap rates.

The Solution: Three Tension Control Points

Corrugated board tension control has three points:

1. Tension sensing. Use tension sensors to monitor paper tension in real time with closed-loop feedback.

2. Automatic adjustment. Auto-adjust via brakes and the unwind system to keep tension stable.

3. Web-break handling. Configure break detection and automatic splicing to reduce downtime.

The Result: Stable Paper, Stable Output, Higher Efficiency

With tension controlled, breaks drop and boards stay flat—line efficiency and quality rise together.
