Web Guide and Alignment Control on the Corrugator: Keeping the Paper Straight at Speed

On a corrugator, paper webs run fast and any drift causes wrinkles, misaligned flutes, and waste. Web guide and alignment control sense edge position and correct it continuously, keeping each liner straight so the board comes out flat, aligned, and ready to cut.

The Scenario: Three challenges in alignment

Web alignment faces three challenges:

Pain Points

• Paper webs drift as they run, causing wrinkles and misaligned flutes;
• Misalignment at speed produces crooked board and edge trim waste;
• Manual correction is too slow to react at production speeds.

The Solution: Three alignment solutions

Web guide control offers three solutions:

1. Continuous edge sensing Sensors track the web edge and detect drift instantly.

2. Automatic correction The guide corrects web position continuously to hold alignment.

3. Straight, flat output Aligned liners produce flat, straight board that cuts cleanly.

The Result: Straight board, less waste

With these controls, the paper runs straight and the board comes out flat and aligned. Web guidance cuts wrinkles and trim waste at the source.
