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.
Claims11
In 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, an edge for contacting a web on the backing roller and supported by a supporting bar and with pressure-adjusting mechanism positioned along the width of the doctor and acting independently of each other in individual positions on the doctor, the improvement wherein the supporting bar is in contact with the doctor below the edge and a portion of the pressure-adjusting mechanism disposed below the supporting bar to act on the doctor to adjusting the pressure of the doctor on the backing roller.
