4 Feet/8 Feet Glue Spreader Machine for Wood Working

Product Overview

At its core, the machine features 415 mm diameter rubber rollers—treated with a wear-resistant silicone coating—that ensure uniform glue distribution across the material surface. These rollers are paired with a variable speed control system (0–90 meters per minute) that allows operators to adjust feeding speed based on adhesive type and material thickness, ensuring optimal coverage without excess waste.

The glue spreader excels at delivering 0.01–0.5 mm thick glue layers with ±5% consistency—a level of precision that prevents common bonding issues like starved joints (insufficient adhesive) or glue squeeze-out (excess adhesive that requires cleaning). It supports both single-sided and double-sided coating, with easy conversion between modes via a quick-change roller system that reduces setup time to less than 10 minutes.

To accommodate diverse production needs, the machine includes a pneumatic roller adjustment mechanism that allows operators to fine-tune roller pressure (from 0.2 to 1.0 MPa) based on material hardness. This ensures proper glue penetration for dense hardwoods while preventing damage to delicate materials like balsa veneer or thin MDF.

Product Advantage

1. Efficient Glue Management

Waste reduction is a key advantage of this glue spreader, thanks to its closed-loop glue recirculation system that captures and reuses 95% of excess adhesive. This system includes a stainless steel collection trough beneath the rollers, a filter screen that removes debris, and a pump that returns filtered glue to the application reservoir. By minimizing glue waste, it reduces material costs by 15–20% compared to open-system spreaders.

The machine’s stainless steel glue hopper (with a 50-liter capacity) is designed to prevent corrosion from water-based adhesives, such as PVA and acrylic glues, while its heated jacket option maintains optimal viscosity for hot-melt adhesives and thermosetting resins. An agitator within the hopper keeps glue homogeneous—preventing settling of fillers in specialty adhesives—and ensures consistent application across long production runs.

For quick material changes, the spreader features a rapid cleaning system that flushes the hopper and rollers with water or solvent (depending on adhesive type) in 5 minutes or less, reducing downtime between production batches.

2. Adjustable Coating Pressure

Versatility in adhesive application is achieved through the machine’s ability to fine-tune roller pressure and feeding speed, allowing it to handle a wide range of adhesives and materials:

For viscous polyurethane adhesives (used in structural bonding), operators can increase roller pressure to 0.8–1.0 MPa and reduce speed to 10–20 m/min to ensure proper spread and penetration.

For low-viscosity PVA glues (common in furniture assembly), lower pressure (0.2–0.4 MPa) and higher speed (60–90 m/min) prevent over-saturation and reduce drying time.

For epoxy resins (used in high-strength bonds), the machine’s precision ensures uniform layer thickness that is critical for proper curing and bond strength.

The spreader also offers pattern coating options—via customizable roller textures—that apply glue in specific patterns (such as dots or stripes) for applications where full coverage is unnecessary, further reducing adhesive usage.

3. Safety and Ease of Use

Operator safety is prioritized with a range of features, including emergency stop buttons at both the front and rear of the machine, interlocked guards that prevent access to moving rollers during operation, and non-slip foot pedals for hands-free control of feeding. These features ensure compliance with safety standards such as OSHA 1910.212 and EN 12431, creating a secure working environment.

Ease of use is enhanced by a user-friendly control panel with clearly labeled buttons for speed adjustment, pressure control, and cleaning functions. The panel includes a digital display that shows current settings and production metrics, such as linear meters coated and glue usage per hour. For training new operators, the machine includes preset programs for common applications, reducing the learning curve and ensuring consistent results across shifts.

Maintenance is simplified by the machine’s modular design, which allows easy access to rollers, pumps, and filters. Critical components are labeled with maintenance schedules, and wear parts (such as roller sleeves and seals) can be replaced without specialized tools, minimizing downtime.

Applications

Furniture Assembly: It coats cabinet doors, drawer fronts, and table tops with edge banding adhesives, ensuring secure bonding of PVC, wood, or melamine edge bands that resist peeling during daily use.

Plywood Lamination: In plywood production, it applies adhesive to core layers and face veneers in multi-ply constructions, ensuring uniform glue distribution that prevents delamination in finished panels.

Composite Panel Production: It applies resins and adhesives to particleboard, MDF, and OSB before laminating with decorative papers, veneers, or plastic films—creating panels used in flooring, wall panels, and furniture components.

Packaging Industry: The machine glues cardboard layers for corrugated boxes and displays, applying precise adhesive patterns that balance bond strength with material savings. It also bonds wood veneers to packaging crates for enhanced durability.

By ensuring uniform glue distribution and minimizing waste, this machine plays a critical role in enhancing the structural integrity, appearance, and cost-effectiveness of wood products across diverse industries.
