A printing unit has a doctor blade chamber, a rotatable roller, and a gasket for sealing between the doctor blade chamber and the roller. One end of the gasket has at least one sealing surface directed towards the doctor blade chamber, the gasket having a thickness which is delimited by a first edge and a second edge at the sealing surface. The other end of the gasket has an elastomeric edge for sealing abutment against the roller, the elastomeric edge being offset in a longitudinal direction of the roller relative to at least one of the first and second edges and delimits the thickness of the sealing surface. The a surface of the gasket extending between the doctor blade chamber and the roller is inclined at an angled of less than 90° relative to longitudinal axis of the roller and/or the sealing surface, and is concave and/or convex. |
