Why change from a pan system to the Pinnacle chambered system?

  1. Reduced VOC emission caused by pan agitation and exposed surface area.
  2. Reduced ink waste from clean up and color change due to substantially less ink in the chamber than a pan.
  3. Faster clean up.
  4. Increased running speeds due to elimination of pan overflow and slinging.

Will my operator be able to use the system?

Designed with positive preset adjustment stops and simple, tool less features, the Pinnacle chambered system performs reliably with little or no operator intervention, shift after shift, job after job. The quick disconnect fittings allow the operator to rapidly change the Ink/adhesive/coating pail and resume production. Clean up of the used pail can be accomplished off line.

What types of inks, adhesives, and coatings are suitable?

UV, aqueous and solvent inks plus coatings and adhesives are commonly used. Each system is specifically designed for your applicator. Several corrosion resistant treatments and materials are available to stand up to your process. Your Interflex sales representative will work with you to ensure the Pinnacle chambered system meets your needs.

Why air load instead of mechanical?

The Pinnacle chambered systems, patented, air actuated, mechanical camshaft loading system takes the standard manual mechanical blade adjustment to the next level of reliability and operator friendliness.

While the Pinnacle chambered systems, manual mechanical adjustment system performs well and is less expensive, the doctor blade life and ease of setup make the air actuated, mechanical camshaft system a worthwhile investment. The patented, air actuated, mechanical cam shaft system is far superior to either a straight air loaded, or air over hydraulic system, due to the inherent nature of air compressibility.

The Pinnacle chambered systems, patented, air actuated, mechanical camshaft uses air, only to rotate a mechanical cam into the work position, thus it is not affected by air compression issues.

Can my press be fitted with the Pinnacle chambered system?

Yes, the conversion to a Pinnacle chambered system requires removal of the old pan or chamber system, then installing a new drip pan, Sunday drive, and mounting hardware. Interflex has engineered and installed systems on a wide selection of existing machinery, and has engineering personal available to measure existing equipment in the field, to insure an accurate and reliable fit.

What is a Sunday drive?

The Sunday drive slowly turns the anilox roll during make-ready and press stoppages, to ensure the ink/coating does not dry on the anilox roll. The ink/coating continues to circulate through the chamber, keeping the doctor blades wet, thus ensuring that there are no dried particles trapped behind the blade to cause streaks.

How does the Pinnacle chambered system decrease "ghosting" problems?

Ghosting is caused by cells, in certain areas of the anilox, not being completely filled with ink before coming in contact with the printing plate. At faster speeds, some pan and chamber designs do not force the ink into the cells. The Pinnacle chambered systems, unique, internal isometric design forces the ink into the cells while moving the exchanged air to the return outlets and lets the air escape to atmosphere prior to the ink/coatings being brought back to the feed tank.

Why do enclosed chambers help in viscosity control and therefore improve print quality?

  1. Due to the small ink volume in the chamber as compared to a pan, the majority of the ink is in the feed tank where defoamers and viscosity control devices can be employed.
  2. The "closed" design of the chamber stops solvent loss caused by turbulence in the pan. This reduces the viscosity change caused and improves consistency throughout the run.

What is the dead band area of an anilox?

While not required, it is recommended that the anilox roll have a 3/8" to 3/4" smooth, polished (dead band) area on both ends of the roll to provide a journal area for the chamber seals to ride against. This increases seal life and prevents dripping.

What is a doctor blade and sealing blade?

Each Pinnacle chambered system has two blades in contact with the anilox. Depending on the rotation of your roll (cw or ccw) the function of the blades can be switched and are interchangeable.

  • The doctor/metering blade is 1" wide, 0.006-0.010 thick, steel or plastic that scrapes the surface of the anilox as it leaves the chamber allowing only the contents of the cells to be transferred to the plate.
  • The sealing blade is a 1-1/8" wide, 0.014 flexible plastic blade that contains the ink in the chamber while allowing the unused ink to re-enter the chamber without excessive back doctoring.
