END SEALS for OFFSET (Coating Unit)

End Seals for the inline Sheet Fed Offset COATING UNIT

End seals play, together with the doctor blade, an important role in achieving a smooth doctoring role. 

The seal’s function is to close the chamber on both sides in order retain the coating in the chamber.

Correct sealing shape and size, so the seals fit exactly to the geometry of the chamber and anilox roller, and seal the corners cleanly.

Correct chamber adjustment with the right pressure to avoid deforming the seal and creating gaps through which coating could leak.
