5.14.4 Adjusting the Air Assist
The air assist is controlled by two factors; air pressure and air assist tube position. The
air pressure adjustment procedure is covered in the Setting the Pressures section. To set
the air assist tube position, be sure the tamp pad is in the home position. Locate the row
of small holes in the side of the air assist tube and loosen the clamp screw. Rotate the air
assist tube until the row of small holes is roughly aimed at the midpoint of the tamp pad
and then tighten the clamp screw.
To check the assist tube setting, use the manual override button on the valve. The back
cover must be removed in order to perform a manual override. Using a small Phillips
screwdriver or similar tool, press the override button on the valve.
Use appropriate eye protection. This step will release a jet of compressed
air from the air assist tube.
5.14.5 Setting the Vacuum
The vacuum pressure is controlled by the air pressure setting on the vacuum valve
regulator. The pressure must be set high enough so the label will stick to the tamp pad
once it is dispensed.
If the unit is fitted with the tampjet option, there is an additional adjustment that can be
made. A flow control, located between the tamp pad and the vacuum generator venturi,
regulates the vacuum pressure applied to the tampjet pad. Using a flat blade screwdriver,
rotate the flow control screw counterclockwise as far as it will go. Cycle the applicator
and note the way the label feeds onto the tamp pad. If the label flaps or flutters during
dispense, adjust the flow control screw clockwise until the label dispense is smooth, even
and consistent.
