2071948 9206796 PCTABS00011 The aim of the invention is to make it possible to vary independently of each other, i.e. better and more freely, the basic parameters in the design of a squeegee used as a flexible-plate doctor blade in a coating-material spreading device. These parameters may include the length of the chamfered surface in contact with the surface to be coated, the resistance to bending strain parallel to the spreading edge of the blade and the resistance to bending strain at right angles to the spreading edge of the blade. This aim is achieved by virtue of the fact that the flexible-blade doctor blade (squeegee) proposed does not have a constant thickness but is made up of two or more different cross-sections with steps parallel to the dosing edge (8), thus giving the flat sides of the doctor blade a substantially terrace-like structure. The blade may also have grooves parallel to the dosing edge.
