Abstract
A roll doctor assembly as dosing element for a coater serving to coat a traveling web (e.g., paper web) features a rotatable doctor bar (14) that extends transversely across the web width. The doctor bar (14) is fitted in a doctor backing (12). The doctor backing (12) extends as well transversely across the web width. According to the invention, the doctor bar (14; 14'; 14') and the doctor backing (12; 12'; 12') are part of a modular system, so that the doctor bar is exchangeable for another with different outside diameter and, consequently, the doctor backing is exchangeable for another with different bearing diameter. The different doctor backings are adapted to one another to the effect that the axes of rotation of the different doctor bars (14; 14'; 14') assume the same position relative to the support beam (10).
