RECOMMENDED SETTINGS

  • Check blade holder for any damages, like dents, nicks or bends. Make sure it is clean on the inside.
  • Use a backup blade of >0,5 mm thickness.
  • Cut backup blade to 45˚ angle at ends. (To reduce cylinder end-wear).
  • Set the blades straight in holder. Make sure there is no waviness in blades.
  • When bolts/screws are used for tightening of blade holder, tighten from center and out crosswise. Use a torque-wrench if possible.
  • Use measuring tape or other precise measuring tool for setting blade extensions. (Or end-stops/pins if present in blade holder).
  • Start with the following blade extensions: Back-up blade 20 mm and metering blade 4 mm (±1mm). If necessary increase or decrease back-up extension.
  • Check doctor blade tip with finger nail for nicks. Be careful, it’s sharp!
  • Tighten blade holder securely to machine.
  • Try to set 55-65˚ attack angle between doctor blade and cylinder.
  • Start with a blade pressure of ≈0,5-1,0 bar, increase the pressure if there is no clean wipe, but try to use as low blade pressure as possible. (Meaning less blade flex and blade/cylinder wear).
  • Set oscillation to ≈20-25 mm (If not possible to reach, use maximum stroke length). Make sure the oscillation stroke is smooth, without jerks or stops.
  • If there is a need to use a “slur-stick” use a very sharp tip and low force (preferably a round stick).
