Product Introduction: Finger Joint Machine

The Finger Joint Machine is a core equipment in plywood production, designed to longitudinally splice short wood pieces or veneers into continuous panels using interlocking comb-tooth joints. It overcomes limitations of traditional scarf jointing (e.g., uneven seams, low efficiency, high labor dependency) and is widely used in producing plywood, multi-layer boards, blockboards, and formwork.

⚙️ 1. Key Technical Parameters

• Processing Capacity:

  • Thickness range: 1.7–60mm (covers thin veneers to thick lumber)

  • Length support: Unlimited continuous splicing (compatible with 4×4 ft to 4×8 ft standard sizes; customizable)

  • Max. width: 500–1100mm (model-dependent)

• Efficiency:

  • Theoretical output: 240–400 sheets/hour (actual ~250 sheets/hour with auxiliary handling)

  • Operators: 1–2 (vs. 6+ for traditional methods)

• Power & Structure:

  • Power: 15–30kW (380V industrial voltage)

  • Core components: PLC control system, servo motors, hydraulic/pneumatic pressure system

  • Joint pressure: 3–10 tons (ensures joint strength > wood itself)

🌟 2. Core Advantages

• Quality & Cost Savings:

  • Seamless joints reduce sanding by 30% and suit high-grade veneer substrates;

  • Saves ~¥25,000/month in labor (replaces 1 scarf jointer + 4 manual jointers, cuts 5 workers).

• Smart & Eco-Friendly:

  • Automated glue application (precision control) + mobile cooling reduces glue waste by 20%;

  • Zero dust pollution (vs. scarf jointing), CE-certified.

• Flexibility:

  • Supports "single-sheet" and "continuous" modes; compatible with hot-melt adhesives (fast-curing glue pellets recommended, cost ~¥0.04/sheet);

  • Modular design for integration with glue spreaders, hot presses, and drying lines.
