Coated material passes through a gap between a metering roll(11) and an opposing surface(14). The diameter of a cylindrical measuring face(16) at one end of the metering roll is smaller than a material contact face(12) of the metering roll. A measuring system(17) determines the gap(b) between the measuring face and a reference surface(18) on the opposing contact surface(14). An Independent claim is made for a process for production of a coated and/or impregnated flat material in which the distance(b) between the two measuring faces(16,18) is determined and used to vary the gap between the material contact faces(12,14). |
