Adjusting the Vacuum

Via the negative pressure the label is fixed to the applicator. This vacuum needs to be strong enough to hold the 

label and cover all suction apertures. It may not be strong enough to hinder the transport of the from the printer to the 
applicator. This is dependent on the label material used. 

The default value of the vacuum is -0.6 bar.

i

Note! 
By adjusting the vacuum it is possible to prevent the label from being applied to the product. If the vacuum 
is too strong the label will not be released by the pad.  

If the vacuum is set too high the advancement of the label can be stopped before it reached the pad 
propperly.

 Vacuum throttle valve

 

Use the throttle valve (1) to ensure that the label is sucked up correctly over its entire surface. 

 

To strengthen the vacuum turn the throttle valve setting screw counter-clockwise.
