Adjustments to the Blowtube (Supporting Air)
For optimal support during the acquisition of the label of the applicator the supporting air is to be set up so that it is
free of turbulence and evenly pushes the label against the pad.
The default air pressure value is set to 2 bar.
i
Note!
When changing the label width (2", 4" or 6") the respective blowtube is to be used. With the correct
blowtube the quantity of blow holes used and the air pressure and blowtube alignment should be adjusted
respectively.

Adjustment to the blow tube
The blowtube (3) for the relative air pressure can be turned on its own axis to optimize the support for the label
acquisition.
1. Loosen screw (1).
2. Insert the blowtube (1) into the blowtube-slot B (2).
Turn the blowtube so that the airflow supports the label from the dispensing plate (5) to the pad (4).
•
For smaller labels turn the holes of the blowtube into the direction of the dispensing plate (4).
•
For larger labels guide a stronger airflow away from the dispensing plate (5) toward the pad (4).
Better orientation can be obtained by using the indicator at the base of the blowtube.
3. Tighten screw (1).

Throttle valve for supporting air
The force of the compressed air can be varied via the throttle valve (1) to improve the blowing onto the label.
To strengthen the supporting air turn the throttle valve (1) counter-clockwise.
