Abstract
A metering system for the coating of webs of paper and cardboard uses a doctor bar received in an elastic bed which is urged toward the surface to be coated by a pressurizable bladder subdivided into compartments. An elastic continuous member between the diaphragm and the bed equalizes the pressure so that sudden changes in pressure in the regions between the compartments are eliminated.
