A composite doctor blade comprises a steel support band (12) configured with (Wa) a width and thickness (Ta) suitable for mounting in a blade holder, with tensile and yield strengths suitable for a selected doctoring application. A wear resistant strip (14) of high speed steel is integrally joined to an edge of the support band. The wear resistant strip (14) has tensile and yield strengths higher than those of the support band (12), and has a hardness of between about 55 to 65 Rc. |
