Abstract
A dosing system with a doctor element fashioned as a doctor rod, for the coating of material webs which are passed over at least one roll coordinated with the doctor element. The doctor element is accommodated in a bed supported by a holder of integral design with the bed and held on the wall of a mounting which at the same time is a bounding wall of the mouth channel for the coating mixture. The holder features on its end on its side opposite the mounting wall a clamping or mounting surface. The holder possesses in the end area of the mounting wall bounding on the feed channel a jump in thickness. On its side opposite the said clamping or mounting surface, a protuberance is provided with a bevel which with the bounding wall of the holder contained on the side opposite the clamping or mounting surface forms an angle between 15.degree. and 55.degree., which bounding wall surface is flush with the surface of the mounting wall.
