System with sealing chamber

A system, comprising:

• a coating form roller;
• a metering roller adjacent to the coating form roller;
• at least one end seal contacting each of the coating form roller and the metering roller;
• and
• a sealing chamber comprising first and second blades, the sealing chamber being defined at least partially by:
• the first and second blades, wherein the first blade is tilted to the second blade, and wherein at least partially between the coating form roller and the metering roller, a distance between the first and second blades decreases toward a nip between the coating form roller and the metering roller, and wherein the first blade is tangential to the coating form roller, and the second blade is tangential to the metering roller;
• the coating form roller;
• the metering roller;
• and
• the at least one end seal.

A system, comprising:

• a coating form roller;
• a metering roller adjacent to the coating form roller;
• and
• a sealing chamber comprising first and second blades that engage with the coating form roller and the metering roller, respectively,
• wherein the sealing chamber has a first end and a second end in an axial direction,
• wherein the system further comprises:
• an outer end seal at each of the first and second end sealing the coating form roller to the metering roller, and
• wherein the outer end seal at each of the first and second ends is pressed against a corresponding end of the coating form roller and is pressed against a corresponding radial surface of the metering roller by a torsional spring.
