ABSTRACT:
A device for unilaterally clamping an elastic doctor blade into a cutting beam. The tension of the blade is varied in relation to a web of material that is to be coated and that runs over a mating roll. The doctor blade rests against the web of material along a doctor line parallel to the cutting beam. The blade is rigidly supported in its midsection along a line of support that is in fixed position with respect to the web of material parallel to the doctor line. The lower edge of the doctor blade can be displaced with respect to the plane of the doctor line and the line of support. The doctor blade is positioned in a longitudinal recess in the cutting beam. The doctor blade is clamped into the longitudinal recess against an elastic resistance in the cutting beam by means of an elastic pressure-medium hose. The lower edge of the doctor blade is guided toward the line of support when displaced out of the plane of the doctor line and the line of support. The geometric relations in the vicinity of the doctor line accordingly remain as unvaried as possible even when the tension on the doctor blade is varied.
