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.

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
  • 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
