Abstract
A coater blade and backing roll combination contains a coater blade having an elastic steel blade with a wear-resistant coating formed thereon. The wear-resistant coating has a hardness greater than that of the elastic steel blade and is provided on an edge of the blade to define a coater surface for contacting with a moving surface of coated paper on the backing roll. The backing roll has a concave outer surface having a curvature corresponding to a quadratic equation and the coater surface has a concave curvature corresponding to the quadratic equation.
