    The simplest roll coating set-up uses a single rotating roller. The bottom half of the roller is immersed in a coating liquid bath and the upper part of the roller is in contact with the fabric substrate (Fig. 10.7).As it rotates the coating liquid forms a film on the roller surface and part of the liquid film is transferred from the roller surface to a fabric substrate.
