Applicator Setup
Weber Packaging Solutions, Inc. 4-7
To align the tamp pad/label:
1. Set the main [POWER ON/OFF] switch to the OFF position.
2. Back the tamp-regulator completely down to 0 PSIG.
3. Loosen the tamp assembly stop and leave free for now (See Figure 4-4).
4. Align the inboard edge of the tamp pad with the inboard edge of the label. This is done
by loosening the manifolds knobs and sliding the tamp pad towards or away from the
faceplate. Tighten the knobs after aligning. (See Figure 4-5.)
5. Align the upstream edge of the tamp pad with the upstream edge of the label by
loosening the two lever handles on the back of the tamp assembly. Make sure the tamp
pad clears the peeler bar and air assist tube when it moves from home to extended
position. There should be a 1/32 to 1/16 inch gap between the tamp pad and peeler bar.
Tighten the lever handles. (See Figure 4-6.)
6. Slowly turn the tamp-regulator back up to 30 psig (2 bar).
7. Set the main [POWER ON/OFF] switch to the ON position. Wait for the applicator and
print engine to fully power up.
8. Press the [JOG] button to cycle the machine.
9. Re-check the tamp pad/label alignment and repeat this procedure if necessary.
Vacuum and Air Assist Regulator Adjustment
To adjust the vacuum and air assist regulator:
1. Turn the vacuum regulator fully closed so vacuum is completely off (see Figure 4-7).
2. Press the [FEED] button to dispense a label. Hold it against the tamp pad with your
finger.
3. Slowly open the vacuum regulator to increase the vacuum until you can feel it holding
the label as you pull your finger away.
4. Press the [FEED] button to dispense another label. If the tamp vacuum doesn’t catch the
label, observe the label as it begins to feed. The air assist must help push the label
towards the tamp pad so the vacuum can catch the label. Increase the air assist regulator
as needed. If the air assist is good, observe the vacuum to make sure the label is caught
by the tamp pad.
If it is not caught, increase the vacuum regulator and re-try.
If it “hops” when feeding, decrease the vacuum regulator and re-try.
