    Abstract: The invention relates to a doctor or coater blade (1) of steel, having a nickel coating comprising abrasion resistant particles, said coating being constituted by an electrolytic nickel layer comprising abrasion resistant particles. The coating preferably comprises at least two electrolytic nickel layers having different composition, and may be formed differently in different sections of the blade. The invention also relates to a continuous process for electrolytic nickel coating in at least one electrolytic cell holding an electrolyte liquid comprising at least one nickel salt, and in at least one of these cells also comprising abrasion resistant particles.

    Abstract: 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, 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.

    Abstract: A method and apparatus for coating both faces of a moving web, such as a paper web in which the web is fed longitudinally at a speed in excess of 200 meters per minute and a coating material is applied to each face of the web, and is smoothed out by means of two blades, one on each face of the web. The blades are formed with a bevel at the point of contact with the web, the width of this bevel measured in the direction of movement of the web is at most 0.08 centimeters and the angle of the blade with respect to the web is less than 25.degree.. Preferably the blades are urged against the web with a force not exceeding 0.20 kgf. per centimeter width of web.

    Abstract: A coating doctor blade having a chamfered face is produced by the steps of forming into a roll a hardened and tempered metal band blank, edge-grinding the blank in the roll, winding off the blank, planing a chamfer surface on one side surface of the blank by moving the blank, in a single pass in the longitudinal direction of the blank, over a single hard metal bit thereby providing a chamfered surface free from scratches and grooves detrimental to the evenness of a coating spread by the resulting doctor blade, and dividing the so-chamfered blank into doctor blades of suitable lengths.
