Frame
WARNING – Do not put hands
beneath upper taping head frame
when upper frame lowers to its rest
position. Severe personal injury could
result.
12 Indicator, Air Pressure
An "Optical" Warning Indicator for the
compressed air circuit of the machine is
located on the upper taping head frame just
behind the red "Stop" button. When indicator
is "Red", air circuit is on.
13 Box Exit Cams
These cams, when tripped by exiting box,
signal drive belts to return to their fully open
(rest) position.
9 Air Pressure Regulator, Upper Taping
Head Frame – Figure 3-5
Set nominally to control "down" pressure
against box. The factory set point is 15 PSIG
[1 bar]. The regulator setting is adjusted as
necessary to allow free movement of boxes
through taping heads while maintaining boxes
flaps in fully closed position. Decreasing air
pressure will increase down pressure on
boxes while increasing air pressure will
decrease down force on boxes.
For boxes which are fully packed with
products that support the top flaps, the
adjustment of this regulator is not critical since
the boxes can support the pressure of the
upper frame at a wide range of regulator
settings. However, if under-filled or fragile
boxes are sealed, this regulator is used to set
the upper frame at the minimum setting while
still maintaining adequate closure of boxes.
The air regulator is adjusted by pulling out to
adjust and pushing in to lock the setting as
shown in Figure 3-5.
10 Main Air Pressure Gauge
Indicates main air regulator pressure setting.
Air regulator should be adjusted so gauge
reads 6.5 bar gauge pressure [95 PSIG].
11 Latching Knob, Upper Taping Head Frame
–Figure 3-6
The mechanical latch is provided to hold the
upper frame at the fully raised position for
tape threading and maintenance.
