3-7. Side Belts In/Out Rates
This is not a routine adjustment. Normally, it is
necessary only after major disassembly or repair of
related components.
Specification
Adjust the Side Belt IN/OUT speed flow controls to
allow the side belts to move to the center of the case
sealer bed at approximately the same speed as they
return to their outer position. The rate of closure (IN)
is the primary measure of a good speed. It must be
slow enough to help center but not bounce a small
box, and not so slow as to reduce the overall produc-
tion rate.
ü Note
If the side belts do not return (move OUT) from the
center of the case sealer bed when no box is present,
refer to Section 3-8, Side Belt Inner Limit, before
proceeding.
Figure 3-6. Side Belt IN/OUT Rate Adjustment
Adjustment
1. Pass an average size box through the case sealer.
2. Observe the rates of side belt closure and return.
3. Adjust the Side Belt IN/OUT speed control
valves, as shown in Figure 3-6 (CW  decreases
speed, CCW  increases speed). These controls
are located on the top of the Pneumatic Control
Panel.
ü Note
If there is any confusion as to where to set the speed
control valves, turn the valves fully CW and then
turn the OUT control 9 full turns CCW and turn the
IN control 6 full turns CCW. Refer to Table 3-1,
Pneumatic Device Factory Set Points and Adjust-
ment Locations.
