ABSTRACT:
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 mm2) 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.
