摘要： A packing (4) for sealing a doctor blade chamber (3), where the packing (4) includes a sharp rail (7) for sealing abutment against a screen roller. The rail (7) is embedded in a resilientmember (20) having a sealing surface (12) for bearing against the bottom (3A) of the doctor blade chamber at the side of the member opposite the sharp rail (7), and where a wall (11) extends from the sharp rail (7) and to the sealing surface (12). The wall (11) extends curving from the rail (7) to the sealing surface (12). By such a design ofa gradual transition is achieved that corners in which ink may accumulate and where partial solidification may occur are avoided. The sealing surface (12) is convexly curving for continuous contactwith the bottom (3A) of the doctor blade chamber, even by deformation of the sealing surface (12) under pressing action (9). Alternatively, or additionally, the wall (11) is running curving from the rail (7) to the sealing surface (12) for reduced deformation of the sealing surface (12) under pressure action (9).
