Gravure and Roller Coating Systems
topic
Gravure coating uses engraved roller cells of defined geometry and depth to pick up and transfer precise coating compound quantities to the fabric surface at coating weights of 2 to 30 grams per square metre, with cell volume and roller speed controlling coating weight at the high accuracy required for thin functional coatings including release coatings, adhesive transfers, and optical coatings where coating weight uniformity of plus or minus 5 percent is required.
Role
Provides precise thin coating application for functional textile coatings requiring minimum coating weight uniformity for release liners, adhesive application, and functional treatment where the gravure cell volume and roller speed combination enables coating weight control precision that knife coating cannot achieve for thin applications, enabling economical thin coating application at high machine speeds for high-volume specialty coated textile production.
