Air Assist Tube
The Air Assist (Drawing L60-I-30D #26) is a tube with a series of holes through
which air rushes assisting the transfer of the label to the Vacuum Tamp or Blow
Head. The air will rush through the tube only when the motor is running and the
label is being peeled and transferred.
It is our experience that as the roll of labels becomes smaller in diameter, some
labels tend to curl after they are peeled from the backing web. The Air Assist tube
blows the label up as it is being peeled, assisting the label onto the Vacuum Head. It
is regulated by a needle valve
(Drawing L60-I-30D #28) attached to the Air
Assist Tube on the front of the machine. This air is supplied by the main incoming
line and is subject to house line pressure. Experience will tell you how much air is
needed to assist the label onto the vacuum head.
Adjusting the Air Assist Tube air pressure
1. Close the needle valve at the end of the Air Assist Tube by turning it clockwise.
2. Cycle the applicator by triggering the Product Switch Assembly.
NOTE: The label will peel, but not transfer to the head.
3. Open the needle valve by turning it counter clockwise ½ turn.
4. Repeat steps 2-3 until the label transfers onto the head with little or no deviation
from a straight-line motion.
