The head is equipped with a pneumatic clamping system for cutting knives. The air first is supplied to the air preparation block which is to clean the compressed air of impurities through the used filter and to set and maintain a constant pressure value. The solenoid valve is controlled through the main control point. The pneumatic system is connected to the head control, when the head is started the pneumatic system is automatically started too.


The head opens on linear guides which guarantees the system's axiality.
