blade screw driver between the number one roll and main drive roll on the bear bands,
noting the pressure when opening and the snap together as you remove it. It should be
about the same on both sides. Now the rolls and the roll gear should be aligned and turn
free using your fingers to turn the rolls without the number two roll in contact with the
main drive roll.
7. Now bring the number two roll into contact with the main drive by rotating the eccentric
on the right and left side to the approximant original position and tighten the roller
tension screw until the washer below the roll boxing is about 1/16
th . below the roll
boxing. Watch to maintain this space while you are adjusting the roll or you could get a
false setting. Move the number three roll
away so it has no contact with the number
two roll. Insert the roll gage between the
one and two roll on the right side of the
roll as indicated in Figure 3. Turn the
right eccentric until there is a very light
tension on the gage block.( a tolerance of
up to + .003 of a inch as long as both
sides are the same.) Repeat the process on
the left side and check back and forth
until both ends are .718 of a inch. Set the
end play the same as you did with the
number one roll. Now loosen the tension
spring screw on both sides until the
number two roll falls away from the main drive roll with changing the tension screw
setting.(not allowing the tension screw to turn while loosing the spring tension.)now
tighten both right and left tension spring screw at the same time until the number two roll
just touches the main drive roll, then a complete one and one half turns on the course
thread adjustment screw or two complete turns on the fine thread adjustment screw.
Check the tension with the screw driver the same as you did on the first roll. The gear
side may feel slightly different due to the mash of the gears.
Figure 3
8. Repeat the same process with the number three roll as you did with number two roll, then
with number four and five roll the same as you did with number two roll.
9.
Now all of the rolls and roll gears should be in line. All
of the idler rolls, (all rolls except the main drive roll)
should have .010 of an inch end play. You should be
able to lay a straight edge from the number one roll
down across the number two roll and the number four
roll on the right and left ends and touch all three rolls.
You should also be able to turn the entire roll bank, (all
six rolls,) with your fingers.
10. See instructions on how to check fold plates and
deflectors to check or install the plates and/or
deflectors.
