The new electro-pneumatic system supplied by Camozzi Automation makes it possible to control the pressure inside the Racla cylinders, counteracting the centrifugal force that would tend to open the same Racla. This is to the benefit of the positioning of the cylinders – therefore of the quality of the print - with a reduced blade consumption and side gasket wear, in addition to constant efficiency of the ink quantity on the cylinder surface.
This result was achieved thanks to an electronic proportional micro-regulator of the Series K8P series running at 12 litres per minute, which has replaced the traditional manual standard pressure regulators and is capable of varying pressure in each individual cylinder, thus controlling it with great accuracy.
To improve the sliding properties of the entire system, low-friction cylinders have been used. Unlike the standard ones, these are activated at a very low pressure, with a much higher sensitivity, which allows rather contained reactivity times.
