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.

Structural Features
The double-sided machine bonds single-sided corrugated paper and facial paper through laminated, heated platen heating, glue paste, and stereotypes to produce flat cardboard
Hot plate surface is ground finished, with 18 pieces of 600mm wide hot plates and 5m cooling stereotypes section
Hot plates made from container board with enclosed pressure container certification and inspection certificates
Internal thermal panels feature partition isolation structure with S-shaped steam flow and steam-water separation function
Pneumatic pressure plate structure with 14 sets of spring pneumatic pressure plates standard
Multi-section temperature control with temperature display for heating plate heat pipes
Upper cotton webbing automatically centered with double cylinder S-shaped cotton web tensioning device
Lower belt uses pneumatic tensioning mechanism with automatic left-right correction and manual adjustment capability
Independent gearbox drive unit with ZG-500 steel gears and oil-immersed lubrication
International brand electrical components for stable and reliable operation
Main drive motor features frequency energy, low-speed torque, wide speed range, and easy maintenance
High-intensity profile main backbone with solid structure suitable for high-speed operation
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
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
Adopts moisture-proof and shock-proof packaging suitable for long-distance road transportation and various weather conditions. A full set of maintenance and operation manuals is included.
