Doctor blade dosing systems for devices used for coating material webs, particularly paper or paperboard webs, exist that have a doctor blade rod, which serves as a dosing element while being held inside a slot of a doctor blade bed that, in turn, is mounted in a support that can be fastened inside the frame of the system. According to the disclosure, the doctor blade rod has a diameter of less than 25 mm. The doctor blade bed is inserted in removable manner into a slot of the support situated on the face thereof. The ratio of the cross-sectional area (measured in mm<2>) of the doctor blade to the diameter (measured in mm) of the doctor blade rod is less than 60 mm, preferably less than 30 mm. The support is made of a plastic material and is shaped like a clamp having at least one rearward extending clamp limb and one joint location, whereby the holding slot that accommodates the doctor blade bed forms the clamp mouth. A tightening tube that presses the slot walls of the holding slot toward one another is placed on a clamp limb.
