Instruction Manual
Older Folder Models
These instructions are written as a generic instruction manual for all older folders. If you
have a Mark 2 or any other folder that has fixed right angle(s), where all sections are
fastened together, ignore information where it mentions height of unit or movement of any
section. The main difference of the fixed frame units is that you must remove the cross
carrier to add the stacker after each unit.
Before working on the folder, DISCONNECT ALL ELECTRICAL POWER SUPPLY TO THE
FOLDER to prevent the accidental start of the folder. Check to be sure you have the
correct tools to complete the job.
For reasons of safety, long hair must be tied back or otherwise secured, garments must be
close fitting and no jewelry, such as rings or necklaces, may be worn while adjusting or
setting up equipment. Injury may result from being caught up in the machinery or jewelry
catching in moving parts.
Good luck and good folding. You have a piece of equipment that was
built with pride, quality parts and quality people.

THEORY OF OPERATION
Buckle Folding
As the sheet of stock leaves the register section, it is picked up
by the #1 idler roll and main drive roll and is driven toward the
paper stop in the fold plate. (See figure 1).
When the sheet of stock advances to the point where it strikes
the fold plate paper stop (See figure 2). The leading edge
stops but the remainder of the sheet is still gripped and being
driven by the rollers. Since the sheet of stock is confined in the
fold plates, it buckles in the space between the main drive roll
and the #2 idler roll. As the sheet continues to advance, the
buckle gets longer and is finally picked up between the main
drive roll and the #2 idler roll and is pulled down between them,
forming the fold.
The number of folds to be made is determined by the job
requirements, but the sequence in which the folds are made is
decided by the machine operator. Folding problems may
require stripping and printing changes. Review the Baumfolder
Imposition Manual for additional information on job layout.
Certain types of folds require that the grain of the stock be
“weakened” along the proposed fold line to ensure a
consistently accurate finished piece. This weakening or
breaking down of the paper grain can be done in a number of
ways, with scoring, perforating and wetting being the most
common.
Fold Plates
The numbering of the fold plates is shown in Figure 3.
The two up plates are #1 and #3 and the two down plates are
#2 and #4.

Register Table Adjustment
When setting up the initial job on your folder it is necessary to start with the adjustment of the
register table.
TO POSITION THE SIDE GUIDE (see figure 4)
Loosen the MICRO-ADJUSTING KNOBS. Turn them to the center of the adjusting range.
Loosen the thumbscrews (underneath the left side of the register board) holding the SIDE
GUIDE. Position the SIDE GUIDE so the end closest to fold rollers is about ¼ inch to the
right of the left end of the knurl of the rollers.
Place a sheet of paper to be run firmly against the innermost edge of the SIDE GUIDE. Slide
the sheet toward the rollers until it is approximately 2 inches from the fold rollers. Lift the first
fold plate out and lay it in a safe place. Turn the hand wheel until the sheet of paper comes
out of the first set of rollers. Watch the sheet to see if it comes out square, or if one corner
comes out before the other. If one corner comes out before the other, move the MICRO
ADJUSTMENT KNOB closest to the feeder in or out to square the sheet to the rollers. THE
SIDE GUIDE SHOULD BE AT A 90 DEGREE ANGLE WITH THE ROLLERS.
Retighten the side guide thumbscrews.
The MARBLE RACK should be positioned with the end closest to the fold rollers
approximately ¼ inch from the SIDE GUIDE and the other end approximately ¾ inch from
the SIDE GUIDE.
The marble closest to the fold rollers should be directly over the TAPE ROLL.
Use mostly glass marbles in the MARBLE RACK except for heavy paper. For heavy paper,
use mostly steel marbles. The purpose of the marbles is to hold the paper against the guide
but not roll up in the guide when running.

REGISTER TAPES
Register Tapes carry the sheets from the feeder to the fold rolls. As many tapes as possible
should be positioned under the sheets carried to the fold rollers, with the left tape directly
under the MARBLE RACK.
Unused tapes should be moved to the extreme right side of the register table.
Wooden spools located beneath the register table control the tape position. To position tapes
loosen the thumbscrew holding the guide spool bracket. Slide the bracket right or left to the
position desired. Tighten the thumbscrew.
To keep the sheet flat as it travels down the register table, place the HOLDDOWN ROD
approximately 1 inch in from the right edge of the paper.
TUCK- IN SHOES
At least three TUCK-IN SHOES are recommended to hold the paper sheets flat for proper
entry into the fold rollers. Place one over each edge and one in the middle of the sheet as
shown.
Additional TUCK-IN SHOES will be required for larger sheets of paper.
Adjust the height of the TUCK-IN SHOES for enough clearance between the shoes and the
paper to eliminate any drag on the paper but still hold it flat.

Procedure for Setting up a
Mechanical Pile Feeder
1. Place a strip of paper approximately 2”
wide and at least 11” long under the
marble holder and against the register side
guide. Move the strip of paper toward the
feeder keeping it against the side guide
until it is a couple of inches past the blow
bar into the feeder.
2. Set the left-hand vertical (angle type) pile
guide one-eighth to one quarter of an inch
closer to the center of the feeder than the
strip of paper is to the register.
3. Place a sheet of the stock to be
folded on the pile feed table, using
the corner guide to locate the sheet
on the feed table.
4. Space the remainder of the vertical
front pile guides across the width of
the sheet. Be sure not to cover any of
the openings on the blow bar.
5. Two paper support clips are provided to help support
the paper over the left-hand corner notch in the feed
table.

(Continued)
6. Loosen the thumbscrew on the air bracket
and blow bar; raise the blow bar as high as
possible. Tighten the thumbscrew.
7. Loosen the two bolts on the air bracket and
move it toward the register table as close as
possible without the blow bar rubbing the pull
out roll. Tighten the two bolts.
8. Adjust the lever
on the blow tube
to a straight up
position so it can
be moved
forward or
backward in the
future. Now
adjust the
circular clips at a
45-degree angle
toward the
feeder. Adjust
the circular clips
on the right and
left front edge of the sheet of paper to be at 90-degree angle.

(Continued)
9. Now load about five inches
of the stock you are to run
on the feed table against
the corner front vertical
guide and the front vertical
guides. The stock should
be properly fanned and
jogged before loading on
the feeder. Keep the stock
as flat as possible. Now
raise the load with the hand
crank until it is about 1-½
inches below the sucker
feed wheel.
10. Install and adjust both the
right and left horizontal pile
angle guides on the right
and left edge of the sheets
close enough to trap the air
but not close enough to
bind the sheets as they
leave the feeder.
11. Two backstops are provided that mount on the horizontal pile angle guides at the tail of
the sheets. This is to prevent the sheets from being blown back from the top of the pile.
12. Loosen the setscrews on the feed wheel and the collar that compresses the spring that
holds the brass plate against the feed wheel and move them until the feed wheel is
slightly off center toward the left side of the folder (operator side). Tighten the setscrew
on the feed wheel. Apply just enough pressure on the collar against the spring and the
brass plate to hold it to the feed wheel, and tighten the setscrew in the collar. The
vacuum when the folder is running will hold the brass plate against the feed wheel, so the
purpose of the spring is to have the brass plate against the feed wheel when the vacuum
is turned on.

(Continued)
13. Center the caliper in front of the feed
wheel. To move the caliper, first trip the
throw off wheel so it will move side to side
then reset the caliper and adjust it to allow
one sheet to travel under the throw off
wheel but not allow two sheets to pass.
This is accomplished by turning the knob
at the top of the caliper clockwise to raise
the throw off wheel and counterclockwise
to lower the throw off wheel. (For
additional information on the caliper, see
Appendix A, information on calipers.)
14. To set the pile height control adjustment,
the adjustment rod screw with the rubber
cone should be aligned behind the feed
wheel, approximately ¼ “ from the trailing
edge of the sheet. Make sure square bars and connections do not bind when lifted and
lowered. It must operate freely.
15. See Appendix B for the instructions on calibrating the pile high control and information
on raising the pile 1,2,or 3 teeth at a time. This calibration should be made before setting
up the feeder or folder and should not change unless something comes loose. For normal
runs, the pile should be set to lift 2 teeth at a time.
16. There are additional shoes and fly rods to mount over the pile to prevent the sheets from
“ bellying “ up. Use as many as necessary to keep the sheets fairly flat when feeder is
feeding sheets The hold-downs should also hold the leading edge of the sheet down as it
leaves the feeder and goes under the marble holder. Also, hold downs on the register
and the shoe on the caliper help direct the paper through the path without catching.
17. Adjust the adjusting rod screw down as far as it goes by turning it clockwise. Make sure
nothing is on the register or binds the folder by turning the hand wheel several times. If all
clear, turn on the folder and allow the pile to raise. The pile should stop about and inch
below the feed wheel. If the pile height control is NOT on the stock in the pile feeder, the
feed board will continue to come up against the feed wheel and damage the folder. Be
sure to watch the lift and if it comes close to the feed wheel, STOP THE FOLDER. Once
the stock has stopped about an inch below the feed wheel, turn the pile height control
screw counterclockwise to raise the stock until it is about three fourths to five eight below
the feed wheel then tighten the locking nut on the pile height screw. Turn off the folder.

(Continued)
18. Turn on the pump control and move the lever on the
blow bar so that the top 5 to 8 or 9 sheets of the
stock are separating. Open the butterfly valve that
controls the blow from the pump and then slowly
begin closing it until sufficient amount separate the
sheets about ¾ of the length of the sheet.
19. If the job is set up on the folder, open the butterfly that
controls the vacuum all the way and slowly close it
until the sheets feed at a regular and steady rate.
20. When loading the feeder, use wedges to cause the top sheets to be level if necessary.

Operating a Friction Feed Baumfolder
To position the LEFT FEED GUIDE, loosen the wing
nuts (underneath the feed table). Position the guide
approximately ¼ inch to the right of the register table
SIDE GUIDE, and parallel to the left edge of the
FEED TABLE. Tighten the wing nuts.
Place a sheet of paper to be run against the LEFT
FEED GUIDE. Loosen the wing nuts on the RIGHT
FEED GUIDE and move it against the sheet. Leave
enough clearance so the sheet falls freely from the
top of the feeder to the PAPER FEED WHEEL.
Tighten the wing nuts.
The angle of the FEED TABLE affects of the fall of the paper as you load it. A
normal setting for most jobs is with the TABLE BRACES set in the third notch
from the top. Some of the feeders have brackets to move the feed table in or
out by relocating the screw in the different holes in the bracket (see picture).
The best location is the third hole back from the retarder adjustment screw.
Position the RETARDER ROLL by loosening the thumbscrew and moving it to
the center or slightly left of center of the sheet in
the feeder. Move the FEED WHEEL directly over
the retarder roll. Check to insure the setscrew in
the retarder roll is tight and the retarder roll does
not turn. Tighten the setscrew in the feed wheel
so it is secured to the feed wheel shaft.
Mount the PAPER GUIDES on the left and right
edge of the sheet. These will go between the
feed board and the FEED PLATE.
Mount the FEED PLATE FORK on the round bar,
with the fork straddling the retarder roll.

Operating a Friction Feed Baumfolder
(Continued)
To correctly position the FEED PLATE FORK, the inside
edge should be ¾ inch in front of the FEED PLATE, as
shown here.
ADJUSTING FOR PAPER FEEDING
Adjust the Retarder Roll to allow a sheet of paper to go between the feed wheel and the
retarder roll by moving the ADJUSTING SCREW KNOB up or down by turning it clockwise or
counter clockwise.
Turn the hand wheel on the folder several times to
insure there is no bind or reason not to start the folder.
Install the feed wheel cover over the feed wheel. If
everything is all right, turn on the folder. Insert the
sheet of paper you will run between the feed wheel
and the retarder roll holding it loosely so not to pull
your fingers into the feed wheel cover, turn the
ADJUSTING SCREW KNOB clockwise slowly until
you feel the sheet pulling out of your fingers. While the
folder is running, paper dust will build up on the feed
wheel. Stop the folder and clean the feed wheel if the
sheets begin to feed erratically.
Turn off the folder
The PAPER GUIDE FLAP slides into the top slot of
the PAPER FEED TABLE as shown here. The Paper
Feed Flap prevents the sheet from “stumbling” on the
feed table slot.
TUCK-IN ASSEMBLIES are mounted on the SQUARE
BAR. One Tuck-in assembly mounts over the left side
of the paper to guide the paper under the Marble Rack
and the side guide. The other Tuck-in Assembly is
mounted over the right side of the paper to guide it
under the Hold-down rod.
The adjustment between the Feed Wheel and the Retarder roll feeds the sheet but also acts
as a caliper. If you are pulling double sheets when feeding, tighten the Retarder Roll slowly
until it feeds single sheets.

Setting up a Job
Before you set up any job, check the sample fold. The folder operator should make sure they
have enough fold plates in the folder you will be using.
For an example: If you have a four-panel wrap around fold, you would need three up plates.
That would mean you would either need a six-plate folder in the parallel or an eight-page unit
(second section) to run in tandem. The four-panel wrap around would fold up in the number
one fold plate then deflect past the number two, three, and four fold plates. Instead of having
the eight-page unit at a right angle to the parallel, it would be running parallel with the
parallel unit. The signature would go straight into the eight-page unit and make the last two
folds in the number one and three fold plates. The purpose of not making two folds in the
parallel unit and one in the eight-page unit is to allow a longer sheet/signature against the
guide in the eight-page unit.
Space will not permit to go through all of the examples of the different folds. Baum has
copies of a book titled “Imposition Manual”. Please call 800-543-6107 for your copy.
** Before starting to set up the job, DISCONNECT THE POWER SUPPLY **
SETTING UP THE FOLDER
1. We will describe setting up a Letter Fold on a three or four plate folder. Remove the first
and third fold plates and lay them in a safe place where they will not get damaged.
2. We will use the number one and three fold plates, going up into the number one fold
plate, deflect past number two fold plate then into number three plate deflecting the
number four fold plate. We will go up one third in number one fold plate, setting the first
fold roller with one thickness of paper. Two thickness will go through number two roll but
the trailing one third will still be one thickness, so the number two roller will also be set at
one thickness. (Always set the roller for the trailing thickness). The paper will deflect
number two-fold plate and go through number three roller, again for one thickness. It still
is one thickness for the last one third of the paper/sheet. The paper goes up in the
number three fold plate one third, now we have three thickness into the number four roller
so, set it for three thickness. We will deflect the number four-fold plate; so number five
roller will be set at three thicknesses. And out the slitter shaft.
3.
Cut two strips of paper approximately two inches wide and twelve inches long. Place a
strip of paper, one on the left end of the roller and one on the
right end of the roller. The strips should be approximately one
inch from the each end of the roller. Using the hand wheel,
back the strips of paper between the number one roller and
the main drive roller about two or three inches, then rock the
hand wheel the other direction to set the rollers. When turning
the fold rollers backwards the rolls separate slightly. If you
test the rollers before turning them forward, you would get a
false setting. After rocking the rollers forward, pull on both
13

1660 Campbell Rd.
Setting up a Job
(Continued)
( step 3 continued )
strips of paper. (The thickness of paper you are going to run).
You want a drag as you pull the strips. If you have a folder
with STANDARD TENSION SCREW ROLLER
ADJUSTMENT, loosen the TENSION LOCKING NUT and
turn the ADJUSTING KNOB clockwise to add tension on the
strip of paper or counter clockwise to reduce tension on the
strip of paper. Once you get an even drag on both strips of
paper, tighten the Tension Locking Nut so the adjustment
doesn’t change. Set the second roller with one thickness the
same as you did the first roller except when you turn the strip of paper in the second roll,
the rollers are turning forward so you do not have to rock it backwards. The third roller will
be set with one thickness the same way as the number one roller. The number four and
five rollers will be set with three strips, on top of each other, or three thicknesses using
the same procedure as with the number one and two rollers. When setting the number
five rollers, you should turn the sheets into the rollers and rock it forward to bring the
rollers back together after backing the strips of paper into the rollers.
4. If you have Baumsets on your folder, read the next
section on how to calibrate the Baumsets. Once
they are calibrated, then all you have to do is put
one thickness of paper in the right and left
baumsets on the number one, two, and three
rollers and three thickness of paper in the right and
left baumsets on the four and five roller.
5. Now replace the number one and three fold plates,
leave the deflectors up because the paper will go
into both of these plates. Lower the number two
fold plate and lower the deflector. We will be
deflecting the number two-plate. Raise the number
two-plate back into position.
6. Repeat the above procedure with the number four
fold plate. You may have a three-plate folder and
have a “dummy” deflector in the number four
position. If so leave it as it is.
7. The FOLD PLATE STOP is equipped with
THUMBSCREWS for major adjustments, and
MICROMETER adjustment for close adjustments.
Set the Fold Plate Stops at three and nine sixteenth and tighten the

(Continued)
14

1660 Campbell Rd.
thumbscrews. Set the number three FOLD PLATE STOP at three and five eight’s.
Tighten the Thumbscrews.
8. Turn one sheet through the folder until it leaves the folder and is ready to enter the
SLITTER SHAFTS. Place a PULL OUT TIRE approximately one inch from the left side of
the sheet on the top shaft and one PULL OUT TIRE approximately one inch from the
right side of the sheet. Turn the hand wheel to allow the folded sheet to leave the Slitter
Shaft. Place two Pull Out tires directly the ones on the top shaft. Be sure to lock the brass
point set screws in the pull out tires so they do not move.
9. Now turn the hand wheel several times to be sure nothing is loose and everything is in it’s
proper position, that hands, hair and all body parts are clear of the folder and that all
guards are in the proper location. Now, start the folder and air pump (if applicable). Run
one sheet and check the fold. Use the micrometer adjustments for the minor adjustments.
CALIBRATION OF THE ZERO BAUMSET DEVICE
Before the automatic roll setting feature can be used, it is necessary to calibrate it to ensure
that the fold rolls are suspended the proper amount when paper is inserted into the Baumset
tension screws. To calibrate the Zero Baumset, you should do the following:
1.
Tear or cut some strips of paper approximately
½” x 1” in length. It is best to use 50-60# offset
stock or equivalent, but some other weight can
be used providing the same stock is used for all
the adjustments.
2.
Push down on the lever for the #1 Baumset on
the left hand side of the folder. Insert a single
thickness of one of the paper strips, prepared in
step #1, in the Baumset tension screw. Gently
push up on the Baumset lever to make sure it is
seated.
3.
Loosen the Baumset knob assembly, which
locks the tension screw in place.
4.
Insert a single thickness of paper stock, of the
same weight as used in the Zero Baumset
device, between the #1 fold roll and the
stationary fold roll. Be sure the paper is free of
tears or folds. The strip of paper should be
inserted approximately 1” from the left hand roll band or between the first rubber
segment of the combination fold roll. To insert the strip of paper, turn the handwheel
Setting up a Job – Calibration of the zero Baumset (Continued)
15
Ph: 1-800-543-6107
1660 Campbell Rd.
counterclockwise, rocking back and forth to be sure the rollers are seated.
(Note: When setting the #3 and #5 Baumsets, it will be necessary to turn the
handwheel clockwise to roll the strip in place.)
5.
Adjust the micro adjustment knob until you can pull the strip of paper out from
between the #1 and stationary roll using a steady, light pull. You should feel an even
drag of the sheet.
6.
Tighten the Baumset lock knob. Remove the pull strips.
7.
Repeat the procedure outlined in steps #2 through #6 for the #1 RH Baumset.
8.
Check the adjustment on both the LH and RH sides of the fold rolls to ensure an even
pull on each side.
9.
Repeat the process outlined in steps #2 through #8 for the #2, #3, #4 and #5
Baumsets. Be sure to use the same thickness of paper throughout the calibration.
To set the Zero Baumset dial, remove all the strips of paper from the Baumset adjustment
gap and:
Locate the micro adjustment knob so that the top is level with the top of the lever. The
Zero Baumset dial should be seated on the stem lock nut. It will be necessary to
loosen the stem lock nut and screw the micro adjustment knob up or down if it is not
level with the top of the dial.
At this time, align the triangle on the lever and the triangle on the Zero Baumset dial.
(See triangle alignment illustration on the previous page) Make certain the Baumset
lock knob is tight so the tension screw doesn’t turn while the micro adjustment knob is
adjusted up or down. Recheck the calibration to be sure the tension screw did not turn.
Retighten the stem lock nut.
NOTE: The micro adjustment knob must be level with the lever to ensure a proper
reference point for the triangle alignment in case the micro adjustment knob is turned
360 degrees up or down. If it is not level indicates that the micro adjustment knob
should be readjusted.
Now the Zero Baumset is calibrated. To set up a job, refer to the operation of the Baumset.
16
Ph: 1-800-543-6107
1660 Campbell Rd.
Setting up a Job – Calibration of the zero Baumset (Continued)
Once the Baumset has been calibrated or zeroed-in the fold rollers can be set automatically
with a designated amount of paper in each Baumset or each roller can be set manually.
To calibrate rolls:
1. Be sure all rolls are closed (together). Turn tension screw until
washer (A ) is just touching Roll Brg ( B ).
2. Insert one thickness paper (small) into each Baumset ( C ) lift lever
( D ) to insert.
3. Using same type paper, cut two strips of paper 2” x 10” and insert
into rolls starting with #1 roller and proceed with same procedure
through #5. (Baumset is number 1,2,3,4,5) Insert strips on right
and left side by lifting lever ( D ) and inserting strips, or with power
off, turn sheets into rolls by turning hand wheel. NOTE: If turning
rollers backward inserting paper, rock them in forward motion to
set the gears to insure rolls together.
4. With lock screw ( E ) loose, turn tension screw counter clockwise
and pull on strip of paper at the same time until you can feel it
starting to move. Repeat same motion on other end of fold roller. Recheck to be
sure both ends of the roll has a snug drag (equal). Lock the tension setting with
lock screw ( E ). Recheck again to insure you still have same setting.
5. Repeat on the #2 then #3 and etc…
STACKER AND STACKER PAN
1. The STACKER can be placed after any of the folding sections depending on the type of
the fold being made.
2. The STACKER WHEELS are
adjustable back and forth for
different length sheets. Lay the
folded sheet/signature on the
stacker with the trailing edge
against the pull out tires on the
slitter shaft, move the stacker
wheels at the leading edge of the
sheet/signature and lock them in
place with the thumbscrews. Two
flat STACKER SPRINGS are
provided to fasten on the square
bar above the slitter shafts. These
should be bent so they hold the
17

1660 Campbell Rd.
Setting up a Job – Stacker and Stacker Pan
(Continued)
trailing edge of the sheet/signature down so as the next sheet/signature comes out, it
does not strike the previous sheet/signature. The Stacker Springs can be bent so they
apply enough pressure to hold the sheet/signature in place until the next sheet/signature
comes out. This is used when you don’t want to use the Stacker Wheels. A map fold is an
example of when you would not use the stacker wheels. The bulk of the folds cause the
maps to jam up at the stacker wheels.
3. There are adjustment screws at the rear of the stacker frame to tighten or loosen the
Stacker Belt, to allow it to track straight. If the stacker belt is moving to the left of the
stacker, tighten the left adjustment. Allow several minutes to allow the belt to respond
before you make another adjustment.
4. Install the STACKER PAN. Now you are ready to run.
FIRST RIGHT ANGLE/ EIGHT-PAGE SECTION
( This instruction can be used for any other rollaway units.)
1. Height adjustment may vary depending on the job you run. For an example, if you want
the sheet/signature to overlap (a sheet leaving the parallel at the same time the previous
sheet/signature is in the cross carrier guide moving toward the fold rollers), you would
have the height of the unit lower. Normal height would be that the top of the cross carrier
would be at the bottom of the lower slitter shaft.
2. The purpose of the cross carrier is to accept the sheet/signature out of the previous unit
and instead of stacking, direct the sheet/signature into the next set of rollers. This can be
in tandem (Straight in line with the previous unit) or at a right angle with the previous unit.
3. Lay the sheet/signature as it leaves the
previous unit on the cross carrier with the
trailing edge at the edge of the left side
of the cross carrier rolls. Hold the
sheet/signature so it doesn’t move and
bring the cross carrier guide so it is
against the sheet/signature. Turn the
hand wheel until the sheet enters the
number one fold plate. If the
sheet/signature jams, move the guide
back toward the right side. If this change
has to be made, you have one of the
earlier models Baumfolders.

Setting up a Job – First Right Angle
(Continued)
4. Square the guide the same way you squared the register side guide. On older
Baumfolders, there are two bolts on each side of the thumbscrew. Loosen the bolts to
move the guide. On the newer Baumfolder, they have micro adjustments. Once the guide
is squared (90 degrees) with the fold rollers, tighten the bolts.
5. Put two steel marbles in the MARBLE HOLDER in the center where the sheet/signature
enters the Marble Guide and one or two steel marbles in the end of the
MARBLE GUIDE just before the sheet/signature enters the fold rolls. Put glass marbles in
the rest of the Marble Holder. Replace the MARBLE HOLD DOWN. Once you are
running, you may have to change some of the marbles to keep the sheets/signatures
against the guide. This depends on the material you are running. The suggestion given
about the marbles is a starting point.
6. The fold rollers and the fold plates are adjusted the same as the first unit. Refer to the
FOLDER instructions. The STACKER instruction is the same.
7. Always score or perforate in the parallel section before going into the eight page section
(first right angle unit). Scoring is not as important when folding the sixteen-page unit
(second right angle unit). You perforate to allow the air to escape. It might be a good
habit to always score or perforate if you are folding even in the sixteen or thirty-two page
unit.

Using Slitter Shaft
Accessories
You can perforate, score, take out trim outs (gutter trim), and end trim on your folder. Once
you know how to use them and what they do, the more profitable your folder becomes. Each
will be described separately but you can use a combination of any or all them together.
Baum produces an Imposition Manuel to show 144 different types of folds and which fold
plates to use for each one, plus the layouts. You can write to Baum for your copy.
We hope this will be of value to you and help to increase your present folder value by
producing more in profits for you. Our ultimate goal is to sell new equipment, but we also
realize our responsibility to you and to the many others who have bought our equipment in
the past. Let us know how we can help you.
Please call 1-800-543-6107 for part numbers not listed. Different folders have different part
numbers required.
The pictures below represent some of the accessories discussed next in this manual.

Center Trim Out
on your Baumfolder
The purpose of the center trim, sometimes called gutter trim, is to be able to print signatures
two up and trim out the center on the folder and chase on the cross carrier into the second
fold section. This allows you to have two signatures at the same time and doubles your
production.
This is accomplished by mounting four slitter blades on four
blade holders. The two top blades and blade holders are
mounted with the sharp cutting edge toward the blade holders.
For ¼ inch trim out, butt the blades together. For a wider trim
out, separate the slitter blades the width you want to trim out.
The bottom slitter blades are mounted with the sharp cutting
edge away from the blade holder. This allows the scissor
action of both blades to push the trim down between the two
bottom slitter blades. That means you have to have a stripper
to deflect the trim down and away from the bottom slitter
blades. You can use the stripper shown in figure 1 that fastens on the bar under the slitter
shafts. If the folder you are using doesn’t have this bar, you can use the brass ring, shown in
figure 2, and a wire around it and let the end of the wire
hang in front of the end frame of the folder. This carries
the trim down between the first section of the folder and
the second section to the floor.
There are other times when you can use the gutter trims.
You can run multiple numbers of religious tracts, or other
types of brochures then cut out trims between them and
cutting end trims off the left and right sides. You can run
from two up on a sheet up to five or six up, depending
upon the size of the folder and the size of the tracts or
brochures.
Figure 3 shows the center trim out being
deflected down to the floor.

Run and cut multiple sheets
at the same time
There are times when you have a small sheet to run such as small religious tracks and it
would be better if you could run them three or four up. That’s no problem. If you want to slit
with no trim out, just install a slitter blade mounted on a blade holder on the top slitter shaft
and one on the bottom slitter shaft with the flat sides together as shown in the picture. Since
there is no trim out, you do not have to be concerned which blade is on the inside and which
blade is on the outside. You do not have a trim out to worry about.
If you want to take end trims and take trims out, read the topics for center trims and end
trims.
Remember when you mount the slitter blades on the blade holder, start the screws through
the slitter blade into the blade holder then slide the collar on the slitter shaft before you
tighten the screws. This aligns the slitter blade and the blade holder.

Scoring on your Baumfolder
The folder can be used to score a sheet and deliver flat, or score a sheet after a fold or folds
have been made.
To ensure accuracy in making right angle folds, always score the sheet where the fold or
folds are to be made. This applies in all instances when a perforator cannot be used. A rule
to remember is to fold up (fold in # 1 or / and #3 fold plate), score down. To fold down (#3
or/and #4 fold plate), score up. There are some, which claim the opposite is correct. Both
opinions are presented so you can try them both and make your own decision. Most of the
folder operators have the first opinion and the paper manufacturers have the second opinion.
There are different types of score blades. The narrow or light score blade is used most of the
time. The heavy score blade or wide score blade is used when folding bulk or several
sheets. You can score against a rubber collar, score between scoring collars, or a scoring
die. To mount the Score Blade on the Blade Holder, place the two screw into the collar
through the score blade. Do not tighten them until the collar and blade are put on the slitter
shaft. Then tighten the two screws.
Scoring against a scoring die gives a press type score.
This is the best type score for hand folds later or
folding in the next fold section. This type score is only
used with folders that have an adjustable slitter shaft.
The score blade runs in the groove in the scoring die.
It is important to center the score blade in the groove.
Adjust the score blade so there is space between the
score blade and the scoring die. Adjust the slitter shaft
to get the best score.
Scoring between two slitter collars is probable the best for
folders without adjustable slitter shafts. The scoring collars have
a rounded side and a beveled side on each collar. The purpose
for this is to create different types of scores. The two rounded
edges toward the score blade create a softer score. The two
beveled edges toward the score blade create a sharper score.
Moving the scoring collars closer to or away from the score
blade increases or decrease the depth of the score. If you use
the scoring collars with one beveled side and one rounded side
toward the score blade, the score will be crooked. As a helpful hint, use the rounded edges
toward the score blade. Take regular cloth tape like you use in first aid, and place ½ on one
collar and ½ on the other collar. The tape will span from one collar to the other. Turn the
hand wheel of the folder until you came to where you started and cut the tape. This will give
you a soft surface to score against. You can still move the collars in and out without
changing the tape.

Scoring
(Continued)
Scoring against the rubber collar gives you a nice score.
For this application, the score blade and the scoring
collar is mounted on one shaft and the scoring rubber
with metal scoring collar on each side of the scoring
rubber on the other slitter shaft. To create a deeper
score, squeeze the collars together against the scoring
rubber as shown in the bottom picture. The one draw
back to this type score is that the more you squeeze the
scoring rubber, the less control you
have after the sheet leaves the fold
rollers. When you apply pressure to
the score blade to create a deeper
score, the less pressure you have
on the pull out tires. The last 7/8inch of the score sometimes trails
off. This can give you problems in
your fold in the second fold unit.

Perforating on your Baumfolder
The purpose in using a perforator is to allow air to
escape. With certain types of folds such as wrap
around folds, it pockets air and it is not allowed to
escape. This causes ripples or “crows feet”. This
is not acceptable in quality printing. The cuts in
the perforation allow the air to escape. Normally
the perforation is in a trimmed area.
You can use commercial perforators for coupons or tear off to return for value, but it leaves a
push out on the back of the paper. This is acceptable in most Mailings.
The perforator holds the sheet and would wrap around the shaft. The stripper is mounted on
the bar above the slitter shaft and between the top and bottom slitter shaft to strip the sheet
off the perforator blade. You can mount it beside the perforator blade and it is less likely to
get caught in the perforator blade.
When fastening the blade to the collar, do not tighten the screws until you slide the collar and
blade onto the slitter shaft. Tighten the two screws and then locate the perforator where you
want it. Mount the perforator collar under the blade with the blade in the wide groove of the
perforator collar. Move the sharp edge of the perforator blade against the edge of the groove
in the perforator collar and tighten the brass point set screw to lock it in place. Then install
the stripper assembly. If you visualize the bevel of the perforator blade as an arrow, the
arrow should point to the next fold section. The parts and the part numbers are listed below.

End Trims on your Baumfolder
Taking off END TRIMS has too many advantages to list here. If you have a printed sheet that
you want to trim off both sides, you can mount the end trims on the folder and save the
operation of the paper cutter. The cut is made on one or both sides and the trim is deflected
onto the floor under the folder. To be successful you should have a trim of at least ¼ inch.
Some have taken a smaller trim, less than ¼ inch, and are successful but most of the time
it’s difficult.
Mount two slitter blades on the blade holder with the sharp side toward the blade holder.
Remember to slide the blade and the blade holder
onto the slitter shaft before you tighten it. Use flat head
screws to mount the slitter blade. Mount two slitter
blades with the bevel side of the slitter blade toward
the blade holder. Mount the slitter blade and blade
holder with the slitter blade with the beveled edge
toward the blade holder on the top shaft, with the
blade holder toward the slitter shaft boxing. Then
mount the slitter blade with the sharp edge toward the
blade holder on the bottom slitter shaft, with the blade
holder toward the slitter shaft boxing on the right side
of the folder. Locate the blade assembly on the top
shaft where you want the out side trim and tighten the
set
screw. Slide the slitter shaft blade assembly on the bottom slitter shaft until the sharp edge of
the slitter blade is against the sharp edge of the top slitter blade and lock it in place. Place a
pullout tire assembly against the slitter blade on
the bottom slitter shaft and one on the top slitter
shaft directly over the one on the bottom slitter
shaft. Space several pullout assemblies to
control the sheet as it leaves the fold rollers.
REVERSE the procedures for the slitter blades
on the operator side. Both of the top slitter
blades should be on the outside. This will cause
the trim to turn down as it is cut, making it
easier to deflect down. Mount the stripper
deflectors as illustrated in the pictures

Knock out Perforator Assembly
A special Knock-out Perforator is available for improved perfect-binding operations and
saddle stitching on your Baumfolder.
When signatures are brought from the folder, they are vacuum fed on most types of binders
and stitches. With some perforations, the vacuum can pull the sheets apart at the
perforations, causing problems with the feeding. By substituting the knock-out perforator, the
signatures hold together, thus reducing the problems on the binders and the stitchers. The
time you save on the finishing equipment will pay for the knock-out perforator. The knock-out
perforator also allows the air to escape when folding all bookwork, and provides an improved
adhesive surface for perfect binding. When using the Knock-out Perforator, the punched out
pieces are separated and stripped from the folded pieces. The initial price of the Knock-out
Perforator may be more expensive, but the life of the assembly is probably two or three
times long than an standard perforator, plus consider the labor and down time you save.
When mounting the perforator blade, the longer part of the tooth contacts the paper first then
the short part of the tooth knocks the knock-out out of the paper, (signature). The blade
holder should be mounted on the shaft so that the knurled knob tightens as the slitter shaft
turns the forward direction. The perforator should be on the top slitter shaft so the pieces of
paper knocked out falls on the floor.

Appendix A - To Calibrate Caliper
Turn Caliper Adj. knob counter clockwise and push down until Throw off wheel
contact the Feed Roll. Loosen set screw ( A ) – insert a Dime (10¢ piece) between
Caliper squaring block and Throw off wheel setting lever. Make sure Draw roll
latch is latched on to caliper reset pin. Apply light pressure down on Caliper adj.
knob and tighten set screw ( A ). Remove dime and adjust caliper by turning Caliper
adjust knob clockwise until one (1) sheet of material you are running moves free
between Throw off wheel and the feed roll but not two (2) sheets.
The set screw with the ½” nut on the left side of the Caliper squaring block should be
set so the block slides up and down free but doesn’t rock back and forth.

Appendix B - Calibrate Pile High Control
Provision is made for raising the pile more or less quickly to compensate for various sizes
and thickness of stock. The ratchet mechanism used to raise the pile can be adjusted to
provide a 1/32”, 1/16” or 3/32” rise per engagement of the ratchet.
To time the feeder for 1/32” or 1/16” rise, remove the cover; position the crank gear and lift
operating arm as shown above. With the lift operating arm in hole A, the ratchet pawl will
move the ratchet two teeth and raise the pawl 1/16”. Be sure the pile height screw is not in
contact with the stock. Adjust the lift stem adjusting nut so the latch pin is just 1/32” above
the pawl lever latch. Loosen the latch pin adjusting screw and position the latch pin 1/32”
away from the pawl lever latch as shown.
When the latch is in the proper position, tighten the latch pin adjusting screw.
A bent wire is mounted on the casting next to the ratchet pawl (not shown). This wire may
be positioned so the free end is under the pawl. With the wire under the pawl, only one tooth
of the ratchet will be engaged, providing only 1/32” rise or vice versa, entails merely moving
the wire. No other adjustments are necessary.
An operator may have previously bent this wire up or down, but by operating the machine a
short time with the feeder empty or with the pile lowered, you will quickly see how the wire
must be adjusted to properly perform its function.

Appendix B - Calibrate Pile High Control
(Continued)
To time the feeder for a 3/32” pile rise, rotate the crank great 180 degrees from what is
shown in the picture on the previous page. This will reverse the positions of holes A and B.
Install the lift operating arm in hole B and adjust the latch pin the same as described for the
1/32 - 1/16 rise adjustment.
If heavy stock such as cover stock is being run and the pile doesn’t seem to come up fast
enough, set the feeder to rise 3/32” per ratchet engagement (three ratchet teeth). When
running very light paper, possibly 1/32” (one tooth) will be sufficient. For the usual run of
paper, having the pile rise frequently in shorter strokes attains more uniform separation. By
watching the operation, one can tell what amount of rise to use.
When the correct pile height as been sensed, the latch
pin should engage the pawl lever latch by
approximately 1/32” on contact. (See figure at right)
This is set by adjusting the engagement adjusting
screw under the latch pin.
