This is part of the air lock group of components. As the name already indicates, it is a type of ionizer which is supported by air flows.

The effectiveness of the Air Knife can be explained by the special design of the air discharge nozzle which creates the  so-called Coanda Effect.
 
The Coanda Effect
In contrast to full flow nozzles, ionized air is discharged from a slotted nozzle, creating a flat jet flow.		 Air flow (Luftstrom) without deflection due to uniform injection
Air,Knife,Haug,North,America
The special construction on the underside of the knife effects a single-sided reduction in the injection (air suction from the atmosphere) which creates a vacuum and ensures that ionized air is directed to the material track.
 
Oben = Top
Schlitzdüse = Slotted nozzle
Ablenkung = Deflection 
Unterdruck = Vacuum
Ionisierungsstab = Ionizing bar
Ionisierter Luftstorm = Ionized air flow

Reducing the injection affords the air blast operated Air Knife ionization unit two particularly positive aspects:

1. The air discharge speed is increased, 
    resulting in increased effective depth. This 
    in turn permits a greater operating distance 
    of the Air Knife to the material line.

2. The slotted flow has a wider angle of 
    dispersion, which is expanded from 24° to 
    33°. A wider surface is therefore covered 
    with ionizing, neutralizing air.		 Air,Knife,Haug,North,America
