Baumfolder Rebuilding a 200 – 700 series folder - Manual (Page 6)

AFTER THE ROLLS ARE INSTALLED.
1. Set the protractor at thirteen degrees. The first roll should be
thirteen degrees toward the delivery end of the fold section.
Make sure the number one idler roll is tight against the main
drive roll when you get the proper degree. Place the protractor
on the end of the roll on the number one roll and the main drive
roller as shown. Refer to your notes to insure the witness mark
is in the correct position as you adjust the eccentric to get the
thirteen degrees. YOU CAN GET THE
CORRECT SETTING WITH THE ECCENTRIC
IN TWO LOCATIONS ON THE ECCENTRIC BUT WHEN YOU GET TO THE LAST
ROLLER, YOU WILL NOT BE ABLE TO GET THE CORRECT POSITION. Therefore
it is very important to set the eccentric in the correct position on each eccentric.
2. NOTE: be sure the High point of the eccentrics are the same directions on both sides.
This is important because of the pivot point and even tension across the roller.
3. To set the endplay, (movement side ways,) on the number one roll, insert a ten
thousands feeler gauge between the collar and the roller boxing. Use a flat blade
screwdriver between the body of the roller and the collar and move the roller towards the
gear side of the roller. Apply very slight tension against the collar and tighten the
setscrew in the collar. You should be able to move the feeler gauge in and out with slight
drag. Separate the number one roll and the main drive roll and work the number one
roller side ways. You should have very little movement.
4. Take the endplay out of the main drive roller without using a feeler gauge. It should not
have endplay but turn freely, without a bind. Tighten the number one roller against the
main drive roller until the washer under the roll boxing has no tension but is still in
contact with the roll boxing.
5. Loosen the setscrew in the tension adjusting screw and
loosen the tension on the spring on the right and left roll
boxing. Now tighten the adjustment tension adjustment screw
until it just begins to put pressure on the spring, then turn the
adjustment screw one and one half turns for an adjustment
screw with course threads or two and one half turns for a
adjustment screw with fine threads. To test the spring tension,
you can insert a fine blade screwdriver between the number
one and the main drive rolls on the bear bands, noting the pressure when the rollers
snap together as you remove the screw driver. It should about the same on both sides.
Now the rollers and the roll gears should be aligned and will turn free when using your
fingers to turn the rollers.
