Reduces single facer glue usage while ensuring reliable bonding quality

• How it works: An automatic sprayer installed at the preheater section reduces glue consumption and accelerates glue penetration, guaranteeing secure adhesion.

Eliminates warping and improves lamination quality for flatter boards

• How it works: At the double facer infeed, the Xiaohua arc-shaped preheating plate combined with the flute tip heating system heats the top and middle board flutes, enhancing bonding and correcting board warp.

Prevents board cracking and corrects warping at low line speeds

• How it works: The double facer outfeed features upper and lower sprayers. When the line runs slowly and the board tends to warp upward, the lower sprayer activates to replenish moisture, correcting warp and minimizing the risk of liner cracking.

Boosts overall line speed by 30–50 m/min with superior board quality

• How it works: The Xiaohua ELS control system connects to the line management system. Based on web width, line speed, and paper grade, it precisely controls spray volume for minimal or even zero-glue usage. This reduces various types of board warp, increases overall bond strength, and eliminates liner blistering on low-basis-weight paper.
