Abstract
A device for coating a web of material traveling around a backing roller, with a flexible doctor having a foot secured in a clamping beam and a point supported by a supporting strip and with pressure-adjusting mechanisms positioned above the width of the doctor and acting independently of each other on individual points on the doctor. The pressure-adjusting mechanisms below the supporting strip act on the doctor. In another embodiment, the pressure-adjusting mechanisms consist of several adjacent chambers that extend over the operating width and can be independently pressurized, each with an elastic wall that faces the doctor.
