Mechanized devices designed to apply a layer of textile strength carrier, such as polyurethane, polyvinyl chloride, acryclic resins, natural or synthetic rubber paste, or similar chemical solutions, to one or both sides of a textile substrate. Unlike traditional chemical finishes, during which chemical treatments infiltrate the substrate's fibers, the coating facilitated by these devices produces a chemical layer in the spaces between the fibers; this coating produces a new chemical structure to strengthen textile materials and promote increased corrosion, thermal, and abrasion resistance. Depending on the type of substrate being coated, these devices can incorporate interroller pressure, knife-spread, dip, spray, powder, extrusion, or UV-cured coating technologies.
