Stable bonding and drying solution for multi-layer corrugated board
The Double Backer is a key section in a corrugator line, responsible for bonding and drying the combined paper layers to form finished corrugated board. This system ensures strong adhesion between layers, flat board surface, and consistent quality during high-speed production.
⚙️ Key Features
- Steam chest heating system – ensures uniform heat distribution and effective adhesive curing
- Continuous double belt pressing – maintains stable pressure without crushing flutes
- Moisture balance control – reduces warping and improves board flatness
- Zoned pressure adjustment – adapts to different paper grades and machine speeds
- Stable high-speed operation – suitable for modern corrugator lines
