ABSTRACT:
A doctor bar consists of two different circular disks that are clamped or fixed in some other way on a cylindrical carrier bar. Circular disks having a smaller diameter and made from elastic material alternate with circular disks that have a larger diameter and are made of a very wear-resistant material, specifically ceramic. The difference in the outside diameter makes for one-half the groove of peripheral grooves of the doctor bar that are formed between the various circular disks.
