AFTER THE ROLLS ARE INSTALLED Continued….
6. Now bring the number two roll into contact with the main drive roller by rotating the
eccentric on the right and left side to the approximate original position and tighten the
roller tension screw until the washer is below the roll boxing is about 1/16”. Watch to
maintain this 1/16” while you are adjusting the roller. Move the number 3 roller so it has
no contact with the number two rolls. Insert the
roll gauge (.812), between the number one roll
and the number two roll on the right side as
indicated in picture at right. Turn the
eccentric in and up toward the roll gauge until
there is very slight tension on the gauge.
Repeat the same process on the left side of the
number two roll and check back and forth until
the tension is the same on both sides and the
eccentrics are within the tolerance of +. 003 of
an inch as long as both sides are the same.
Remember you can get the proper setting with
the high point of the eccentric in two different
locations, but if you have the eccentric in the
incorrect position, you will not be able to adjust the last fold roller. Set the endplay the
same as you did the number one roller. Now loosen the setscrew in the tension spring
nut and loosen the spring on both sides until the number two idler roller falls away from
the main drive roll. Make sure the tension screw does not turn. Now tighten both the right
and left tension screw nuts slowly until the number two idler roll just touches the main
drive roll. Then turn the tension adjustment nut one and one half turns on the course
thread tension screw or two complete turns on the fine thread adjustment screw. Check
the tension with the screwdriver the same as you did on the first idler roll. The gear side
may feel slightly different due to the mash of the roll gears.
7.
Repeat the same process for the number three idler roll and then for the number four
and five idler rolls.
8.
Now all the rolls and roll gears should be in line. All of the rolls
should have .010 thousands end play except the main drive
roll and you should be able to turn the rollers with your fingers.
You should be able to lay a straight edge across the number
one roll, number two and the number four rollers as indicated
in the picture. The same is true underneath with the main
drive roller, number three and number five rollers.
