For boxes which are fully packed with products
that support the top fl aps, the adjustment of
this regulator is not critical since the boxes can
support the pressure of the upper frame (drive
belts) at a wide range of regulator settings.
However, if under-fi lled or fragile boxes are
sealed, this regulator can be used to set the
upper frame pressure to a minimum that is still
adequate to positively convey the box and to
prevent damage of boxes. The regulator setting
can be locked by securing the lock nut on the
regulator shaft as shown in Figure 7-17.
Note – A precision regulator is used to balance the
top drive assembly. Due to the self-relieving
feature of this regulator a small amount of
air will continually vent to the atmosphere.
This is normal and amounts to approximately
3 liter/min [0.1 SCFM ].

Indicates main air regulator pressure setting.
Air regulator should be adjusted so gauge
reads 5 bar gauge pressure [70 PSIG].
9. Mechanical Latch, Upper Drive Assembly –
Figure 7-18
The mechanical latch is provided to hold the
upper drive assembly at the fully raised position
for tape threading and maintenance.
To raise and latch the upper drive assembly:
1. Push and hold the upper frame-raising
switch "A".
2. Push and hold latching knob "B".
3. Release switch "A".
4. Release knob "B".
5. Shut off air supply.
To release and lower the upper drive assembly:
1. Turn on air supply.
2. Push and release switch "A".
10. Indicator, Air Pressure
An "Optical Warning Indicator" for the
compressed air circuit of the machine is
located on the upper drive assembly just
behind the red "Stop" button.
When indicator is "Red", air circuit is on.
