• Corrugated Cardboard Production Line

Double Facer Machine

Double Facer Machine – Core mainframe of the corrugated board production line. Single-faced corrugated board enters after glue application, and is bonded, dried, and cooled via heated platens, producing flat, high-strength finished board. Supports continuous production of 3-, 5-, and 7-layer boards, compatible with LUM-A/B/C entire line, effective width 1400–2800 mm, operating speed 60–250 m/min.

1. Core rollers in high-quality Cr-Mo alloy steel or cemented carbide – heat-resistant, wear-resistant, suited for long-term continuous operation.

2. International UV standard fluting profiles – low paper shrinkage, flat finished board with high strength.

3.Key components machined via precision grinding and computer-positioning – dimensional accuracy meets national standards.

4. Independently controlled zone heating on platens – uniform heat distribution, firm bonding, minimal blistering/delamination.

5. Stable conveyor belt with adjustable pressure – ensures flat, distortion-free board across various paper weights.
