The print cylinder is tightly held by our exclusive patent pending Pitagora ^TM "3 pressure points" configuration, and is specially locked from beneath, on a "guide-less " geometry. This unique design allows immediate changeovers despite the different sizes, and a totally vibration free operation for the print cylinder at every speed, and during the years.
Furthermore, when the Flower ^TM  opens the anilox roller becomes immediately available for change, fully disengaged from the print unit. It can be taken with one hand, or with a simple tool (the Spider) if the operator wants to keep his hand clean. The same happens to the rubber roller, which is fully disengaged and available for change. Another Spider tool prevents the operator from getting his hand dirty with ink. The doctor blade assembly includes the side wipers and it is immediately disengaged, for a quick doctor blade change. The ink tray follows the Flower ^TM  movement, and it can be changed in any position of the Flower ^TM .

When changing the anilox roller or the diameter of the print cylinder, no printing pressure or anilox pressure adjustment is requested, due to the special Pitagora ^TM  locking mechanism, which locks the print cylinder from beneath. Changing jobs becomes just a matter of putting the print cylinder in, whichever diameter, and printing at maximum speed. A very simple adjustment is made only when the thickness of the substrate changes.
The same Pitagora ^TM  concept eliminates any pressure adjustment when the printing speed changes. Due to the revolutionary geometry of the Flower ^TM  head, all the guides are eliminated and the mechanical vibrations or wear have no influence on the print quality, as all the tolerances are recuperated, especially at very high speeds. The doctor-blade assembly too has been specially designed to avoid any adjustment by the operator. A unique doctoring configuration allows ink-spitting free operations in every working condition. No mechanical or pneumatic adjustment is required. Just, "closing " the Flower ^TM ,the Doctor Blade assembly fits into the correct position, and no adjustment is needed by the operator. Also the rubber roller does not need any adjustment, and fits into the correct pressure adjustment, at any speed, without any screw adjustment by the operator.

The length register adjustment acts on the print cylinder, and not on the impression roller. No stress is given to the tension of the web, and all the register corrections are immediate, without any influence on the previous and following colors, and a minimal paper waste. Only high precision hardened certified ISO Din Class 5/6 helical gears are used on the Flower ^TM  print station, to ensure the maximum print quality, guaranteed in the years. The print unit is entirely made with steel frames, on a steel platform, to maintain the same quality performances during the years.
