2 stage paper Coating Machine

-Stage Paper Coating Machine is a specialized system designed to apply two successive layers of coating material—such as clay, latex, or pigment-based formulations—onto paper or paperboard to enhance its surface smoothness, gloss, printability, and strength. It is widely used in the production of coated printing paper, art paper, packaging board, and specialty grades where high-quality surface finish is required. The machine typically consists of two coating stations arranged in sequence, each equipped with a coating head (like an air knife, blade, or rod coater), drying section, and web handling system. In the first stage, a pre-coat or base layer is applied to fill surface irregularities and improve coating adhesion. After partial or complete drying through hot air, infrared, or flotation dryers, the paper moves to the second stage, where a top coat is applied for the final surface finish—giving enhanced gloss, brightness, and print uniformity.
