One-sided corrugated cardboard production lines often encounter the issue of corrugated jumping during the production process of single corrugated cardboard. Jumping refers to:

Poor corrugation forming with uneven heights and sizes, where the base paper does not form normal corrugation and deforms, is called jumping. This phenomenon only occurs on single-sided corrugated cardboard.

Causes -- Solutions

① Excessive or insufficient moisture in the corrugated base paper -- If the moisture is too high, increase the preheating area; if too low, use steam for humidification.

② Inappropriate braking force of the corrugator (too high or too low) -- Adjust the friction of the brake to achieve the appropriate state.

③ Insufficient or uneven pressure from the corrugating rollers -- Adjust the pressure of the corrugating rollers to make it suitable.

④ Dirty or damaged corrugating rollers or worn bearings -- Replace or clean the dirty parts or components.
