Baumfolder Rebuilding a small, older folder - Manual

Section 1 - How to Rebuild a Baumfolder
NOTE: There are several bolts with the same diameter and thread but different lengths.
Do not interchange bolts of different lengths. The length is very important.
1. Before working on the folder: DISCONNECT ALL ELECTRICAL POWER
SUPPLY TO THE FOLDER to prevent accidental start of the folder. Check level
across the number one roller and from front to back of left and right frame. Check to
insure you have all the parts and tools necessary such as reamers, gauges, and etc. It is
helpful to clean area around the folder so if you drop anything, it will be easier to find.
2. Remove all guards covering area where you are working. If side guard you are removing
has electrical wires in it, do not stretch the wires. The wire may pull out of the terminal
and cause a short when you check the folder. Normally the wires are long enough that the
controls can be placed in a position where it is out of the way while working on the
folder. You may have to remove the hand wheel on the 500 series to allow the wires to
pass between the frame and the throw off rod. Caution should be exercised when
replacing the guard not to pinch lead wires between the guard and the frame causing a
short in the electrical system.
3. Remove drive belts. If you are not familiar with the equipment, I
suggest you put tape on the belt and identify its location for later
convenience.
4. Remove the drive gears on the outside of the frame
on the non-operator side of the folder section you
are working on. Use your parts book if you have
trouble remembering how it goes back or draw a
sketch for future reference.
5. Remove fold plates on the section you are working
on. Store them in a manor that the nose of the fold
plate or the plate itself is not damaged.
6. To remove the fold rolls, loosen the set screw in the collar
of each fold roll (usually on the left end of the fold roll)
and move collar toward the body of the fold roll.
7. Make a note of the location of the witness marks for
future reference. You can achieve the proper space
between the fold rolls with the eccentrics 180 degrees off
until you get to the number 5 fold roll. You want to know
where to start when setting the rollers.
8. Do not remove the plate rails or if applicable the eccentric deflector studs. You can
remove the fold rollers with the rails and studs in place. This will save time later when
setting fold plates.
