Signature labeller - Air flow adjustment of blow bar
There is an in-line air flow restrictor in the pneumatic circuit for control of air to the blow bar.
It is also important the correct angle of the blow bar is maintained to ensure good label placement onto the
applicator shoe.
Adjustment of the restrictor may be required depending label shape and size.
Remove the rear labeller cover and adjust this restrictor to change the air
flow through the blow bar.
The standard setting for this restrictor is to fully tighten and then un-screw 4
+/- 0.5 turns
The angle of the blow can be
adjusted to suit the label
length.
As a guide, shorter label will
have the greater angle (30°),
and as the label length
increases, the angle to set
will be decreased (down to
15°).
Air blow angle of 15° to 30°
