Screen Rotary Coating for Functional Patterns
topic
Rotary screen coating uses nickel screens with photoengraved pattern apertures rotating against the substrate, forcing compound through open screen areas by an internal squeegee to deposit defined pattern areas of coating compound for discrete application of adhesive dots, functional agent patches, or decorative coating patterns that would not be possible with continuous knife or gravure coating methods.
Role
Enables patterned coating application for discontinuous functional treatments including thermobondable adhesive dot arrays for interlining fabrics, antimicrobial agent zones on medical textiles, and decorative pattern coatings where the defined aperture pattern of the rotary screen controls the coating deposit geometry with the precision of screen printing, enabling the design of specific coating pattern configurations for optimised functional performance.
