Abstract:
1. A method for producing two metal doctor blades that are suitable and adapted for distributing and wiping off a liquid or a paste from a cylinder, the two metal doctor blades each providing an area of reduced material thickness and each providing a working edge, the material thickness being constant in the area of reduced material thickness, wherein said method comprises: a step of providing both areas of reduced material thickness by performing a single planing operation in a basic body; wherein the basic body is provided having a constant material thickness over its extent; wherein the single planing operation in the basic body simultaneously forms both areas of reduced material thickness; wherein the extent of the formed area of reduced material thickness provides an amount of material, having a reduced thickness, necessary to form the two metal doctor blades; a second step after the single planing operation, of performing a separating operation; wherein the separating operation includes separating, by cutting, the basic body, having the area of reduced material thickness, in the area of the reduced material thickness; wherein the two metal doctor blades and the two working edges are formed by the separating operation; and wherein the two metal doctor blades are suitable and adapted for distributing and wiping off a liquid or a paste from a cylinder.
