Abstract
A device for coating continuous webs with regulable coating strength by means of a doctor rod that rests against the coated side of the web, that is mounted in a doctor bed, and that can be elastically forced with regulable pressure against the web being coated. The doctor rod is a doctor batten that moves with little friction along at least one overflow-side slide face of a rigid doctor bed. The face of the doctor batten toward the web that is being coated is rectangular and demarcates in conjunction with the web a narrowing coating-material application gap with a geometry that depends on the degree of contact pressure. The upper edge of the face constitutes a straight and sharp stripping edge. The face and stripping edge of the doctor batten are flexible. Its face is highly resistant to wear. The contact pressure is exerted by an inflatable means of exerting pressure positioned between the batten and the bed.
