Equipped with precision-metering blade, comma, or air-knife coating assemblies engineered for aqueous barrier emulsions, clay slurry, and barrier coatings. Ensures high coat weight uniformity and flawless surface smoothness at extreme line speeds up to 750 m/min.
Features an industrial-scale multi-zone drying tunnel with high-velocity air nozzles and individual thermal regulation. Evaporates high moisture volumes rapidly without blistering, case-hardening, or thermal degradation of heavy paper fibers.
Multi-axis closed-loop vector drives and anti-deflection steel guide rollers across wide spans (1400–2900 mm). Suppresses web fluttering and compensates for caliper variations across heavy paper grades, effectively eliminating web snap.
Integrates floor-level shaftless hydraulic unwinding, continuous coating, multi-stage drying, and high-capacity surface rewinding into an uninterrupted workflow. Engineered for demanding 24/7 industrial packaging conversion with minimal operator intervention.

Turnkey Production Line Upgrades:
Note: Optional auxiliary modules communicate via centralized industrial fieldbus directly into factory SCADA systems.
A: High-speed coating demands rigid fluid dynamics. The machine integrates pressurized coating delivery chambers, dynamically balanced backing rollers, and high-frequency servo blade gap adjusters that prevent hydrodynamic lift, maintaining strict coat weight profiles across the full 2900 mm width.
A: The system incorporates multi-stage closed-loop tension zones with high-resolution digital load cells and low-inertia carbon/aluminum rollers. This architecture isolates tension disturbances during acceleration and deceleration, preventing web elongation and web breakage across 50–450 g/m² paper grades.
A: As an integrated machinery builder in Guangdong, MEAREG provides complete plant layout engineering, thermal heat recovery piping plans, and full Factory Acceptance Testing (FAT) with client paper rolls before seaworthy containerization. We deploy experienced commissioning engineers worldwide for complete mechanical and electrical turn-on.
