Abstract
Process and apparatus for glazing a material web so as to influence or control the transparency of a material web. The material web is guided through at least one nip which is formed by a roller having an elastic covering made, in particular of a plastic reinforced with fibers or appropriate fillers, and an opposing roller. In one embodiment, a primary orientation of the fibers in the covering is selected as a function of the desired glazing result. In another embodiment, the roller surface has uniform nonhomogeneous hardness distribution over a substantial portion of its rolling surface.
