Product Description
Double Facer For Corrugated Cardboard Production Line
The double facer, also known as the double backer, is the "forming hub" of a corrugated board production line. It is responsible for bonding single-face corrugated board with a liner (face sheet) and pressing them into sturdy double-wall or multi-wall corrugated board. It is a key piece of equipment that determines the final physical strength and quality of the board.

Production Line Position and Process Flow
The double facer is typically located after the single facer and before the dryer/cooler section, serving as a connecting link in the corrugated board production process.
Typical Production Flow:
Single-face corrugated board → Double facer (adhesive application, liner lamination, heating/pressing) → Drying and Cooling → Slitting and Scoring → Stacking
Main Types and Selection Reference
- Heated-Plate Double Facer: Most common type using upper and lower heated plates for pressure. Large contact area, suitable for medium- to high-speed production lines
- Vacuum-Assisted Double Facer: Uses vacuum belt for transport, reducing friction between board and heated plates. Suitable for heavyweight, high-strength boards
- Air-Cushion Double Facer: Provides even pressure, suitable for producing thin or lightweight boards, effectively preventing flute crush
Key Operational and Maintenance Points
- Temperature Control: Heated plate temperature must match line speed. Higher speeds require higher temperatures to ensure complete adhesive gelatinization
- Pressure Adjustment: Excessive pressure flattens flutes (flute crush), reducing strength; insufficient pressure leads to poor bonding
- Routine Maintenance: Focus on cleaning heated plate surfaces to prevent carbon buildup affecting heat transfer; check canvas belt or conveyor belt tension to ensure smooth transport
Packing and Shipping
