• Application : Automatic Reverse Roller Coater features a counter-rotating applicator roller that effectively levels the paint surface, eliminating roller marks and orange peel. It is the perfect choice for applying topcoats on high-gloss furniture and flooring.

A reverse roll coater is a key component of wet coating strategies. Unlike other roll coating systems, this machine features two counter‑rotating nips. In a typical configuration, the applicator roll and metering roll rotate in the opposite direction to the substrate. The applicator roll surface accumulates excess coating before reaching the metering roll nip, enabling precise control of the final coating thickness. This equipment is designed for high‑end surface finishing, effectively eliminating roller marks and orange peel texture, making it ideal for achieving mirror‑like high gloss or premium matte finishes.

• Superior surface quality: Produces perfectly smooth, uniform finishes – suitable for high‑gloss piano finishes or ultra‑matte effects.

• Wide processing flexibility: Handles a broad coating thickness range and a wide viscosity range; capable of applying very thin, uniform wet films at low speeds, as well as thicker coatings than forward roll coating.

• Independent drive system: The applicator roll, metering roll, and conveyor are each controlled by separate motors and inverters, ensuring excellent stability and precise adjustment.

• Efficient coating circulation: A pump‑driven circulation system with a trough recovery function significantly reduces material waste – coating consumption can be reduced by more than 50% compared to manual spraying.

• Broad substrate compatibility: Works with wood, MDF, veneered panels, and many other substrates for both primer/sealer smoothing and topcoat application.

The applicator roll and metering roll rotate opposite to the substrate direction. The applicator roll picks up excess coating before entering the metering nip. The substrate moves around the bottom of a support roll, which scrapes the coating from the applicator roll onto the substrate. Meanwhile, the substrate travels in the opposite direction to a rubber‑covered backup roll. The gap between the metering roll and the applicator roll controls the amount of coating delivered to the substrate. In addition, the rotational speed of the applicator roll directly affects the coating weight – higher speed yields more coating, and vice versa. This design allows the coater to perform well when coating speed needs to be changed.

• Superior Finish Quality: Delivers flawlessly smooth, uniform surfaces ideal for high-gloss piano finishes or ultra-matte effects.

• High Cost Efficiency: Reduces paint consumption by over 50% compared to manual spraying; the recycling system ensures near-total material utilization.

• Productive & Stable Operation: Automated process increases throughput, reduces labor, and offers excellent environmental performance.

• Versatile Process Application: Suitable for both topcoat finishing and sealer/primer smoothing before sanding.

• Wide Substrate Range: Compatible with wood, MDF, veneer panels, and more for both primer and topcoat applications.
