SAFETY FIRST
BASIC
10. Make sure that all safety devices are in place before
restarting the machine.
Y our new BAUMFOLDER paper folding machines have been
designed in accordance with the latest safety specifications.
The warning and caution labels on the machine must remain
in place. Make sure all guarding provided is in place before
starting up and running the machine.
Due to the nature of the work process of paper folding
machines, there are parts and areas on the machine which
cannot be completely covered without interfering with the
operation of the machine. Therefore, sound personal work
habits and strict observance of all safety precautions is
required for the protection of the operator, co-workers, and
the machine.
Be certain to follow these
safety precautions:
1.Study the safety instructions at your plant and those
provided in this manual.
2.Study the operating instructions carefully before
operating the machine.
3 .Make sure that your co-workers are familiar with the
work process, potential danger areas,
and all necessary safety measures.
11. Never clean moving parts of the machine (rollers, shafts,
etc.) or remove any test sheets or paper jams while the
machine is running.
12 . Keep the floor around the entire machine clean. Immedi-
ately clean up any oil, grease, or paint spills from the
floor . Remove tools, cleaning cloths, and paper scraps
from all work areas.
13. Never allow unauthorized personnel to make adjustments
on the machine, remove problem sheets, or start the
machine.
14 . Never climb over the machine or crawl into it while it is
turned on.
15 . Immediately repair or replace any safety devices which
have become ineffective or are missing.
16. Report any exposed cables or exposed electrical connections.
17 . Always have a certified qualified electrician perform all
electrical maintenance.
18 . Do not make adjustments or perform maintenance with
the power on.
4 .Make sure that the machine is in good working order
before turning it on.
5.If the machine suddenly stops for whatever reason, do
not restart it right away. Someone may have stopped the
machine, but failed to press the emergency (Stop)
button. If the machine is restarted unexpectedly , your
co-worker could be seriously injured.
6.Always press the emergency (Stop) button first if you
stop the machine for adjustments or maintenance work
which must not be done while the machine is in operation.
7 .For extensive maintenance or repair work, turn off the
main power supply .
8 .Never use improper or defective tools.
9 .After making adjustments or after doing maintenance or
repair work, always make sure that all tools and other
objects are removed from the machine. Otherwise, they
might fall into the machine, causing severe damage or
injuries.
19 . Become familiar with and follow the safety labels on the
next page. Replace any of these labels that are damaged
or lost.
Additional Notes:
20. Do not attempt to remove a paper jam, no matter how
minor it may appear to be, while the machine is running.
21. When cleaning the fold rolls, use the handwheel for
turning. Be sure the power to the machine is off.
22. Turn off the machine before making any adjustments to
the scoring, perforating, or slitting attachments. Keep
hands and clothing away from the slitter shafts when the
machine is running.

How The WetScore Works
5 . Keep all tubing away from fold rollers. Do not
operate the folder without guards in place.
The WetScore is designed to give you absolutely
straight, tight and consistent folds out of your existing
folder.
New or well used, your folder will show an improvement
in perfomance with the addition of the WetScore; increased
running speeds, tighter more accurate folds, less waste and a
reduction of downtime.
The WetScore applies a fine line of an alcohol/water
mixture to the sheet, breaking the grain of the stock, prior
to the sheet entering the fold rollers. This eliminates the
bother of getting a straight score out of the parallel section
of your folder. The wet line applied to the sheet on the
register table is always straight, as long as the sheet
registers to the guide before reaching the WetScore needle
applicators. For this reason the WetScore is installed on the
folder as close to the fold rollers as possible.
The WetScore applies a fine line to the stock regardless
of the speed at which the folder is running. By placing the
needle applicators directly upon the stock, the surface
tension of the fluid is overcome and the WetScore is able to
apply the fluid to the stock by capillary action. The effective
result of this action is that the faster you run the folder, the
faster the flow of fluid onto the stock! For this reason it is
essential that the needles are always in contact with the
surface of the stock when using the W etScore.
6.To avoid unnecessary wear of the tubing, keep tubing
from resting on the cross carrier drive rollers of the
right angle unit.
7 .Prolonged operation of the WetScore will result in the
heating of the shut-off solenoid. Use caution when
handling.
8 . Alcohol/water solution is flammable. Keep away from
excessive heat or open flame!
The WetScore is the only product of its type that
features an automatic shut-off to prevent build-up of fluid on
the folder. The shut-off is accomplished by a signal sent
from a photoelectric sensor to a control modulated amplifier.
The amplifier has a built in delayed off signal that is preset at
the factory for 1 second. If the WetScore sensor does not
detect a second sheet within 1 second, the Amplifier will
send a signal to the solenoid stopping the flow of fluid to
the control valves. For this reason a small amount of fluid
will be seen falling between sheets during the running of a
job, as well as when the folder stops running.
MACHINE SAFETY
1 . Needles are Sharp! Place needles in needle holders
on control amp base when not in use. Use caution
when handling!
2. Unplug WetScore when not in use.
3 . Wipe up all spills.
4. Do not operate without the amp housing cover in
place. No user serviceable parts inside.
PAGE 5TP10320A
SET UP
1.0 THE RIGHT ALCOHOL/WA TER
MIXTURE
3.0 BLEEDING AIR FROM THE TUBING
The WetScore uses a mixture of Isopropyl ALcohol
(Commonly known as Rubbing Alcohol) and water . The
alcohol serves two purposes. First, it acts as a drying agent
to cause rapid evaporation of the solution from the signatures. Secondly , it insures that the fluid maintains a uniform
line upon the stock. For these reasons it is important that
the solution be mixed in the proper proportions. T oo little
alcohol in the solution and the fluid will tend to spread out
upon the sheets in a ribbon rather than a fine line and the
signatures will feel excessively wet. T oo much alcohol and
the fluid will have a difficult time absorbing into the stock
and inconsistent folds will result.
As a rule of thumb, during operation of the WetScore
the signatures should feel wet to the touch immediately after
folding and dry within 3 to 5 minutes. You should be able to
smell the alcohol on the signatures. The folded signatures
should appear flat. If the signatures appear to be rippled
along the scored and folded edge you are using too much
water and we advise remixing your solution. To avoid
unwanted downtime, we advise keeping a premixed container
of solution nearby the folder to fill the water bottle during
operation of the WetScore.
The Greatest factor in insuring a strong flow
of fluid through the WetScore is the asbence of
air in the tubing that runs from the bottle to the
control valves.
A. BLEEDING THE TUBING FROM THE
ON/OFF SOLENOID TO THE CONTROL
VALVES
1 .Plug the WetScore into a 110V . outlet.
2 .Make sure that the LED indicator light on the
photoelectronic sensor is not lit,indicating that
the solenoid is closed.
3 .Close all of the control valves.
4 .Remove the rubber cap from the end port of
the control valves.
5.Place a rag over the open port to catch fluid
when the solenoid is opened.
2.0 DETERMINE THE NUMBER OF
SCORES
In most cases you will want to use the WetScore when
you are folding in the 8 page (right angle). We recommend
using the WetScore not only for those situations in which
you would normally use a mechanical score, but for folding
with perforators as well. The WetScore is not meant to
replace the perforators, but operates in addition to them.
The resulting signatures will be flatter, usually eliminating
dog-ears and assuring you straight perforations.
6.Place your free hand under the sensor to
open the solenoid.
7.Allow fluid to run through the system until no
air is visible in the tubing between the solenoid
and the control valves.
8 .Remove your hand from under the sensor,
when the flow of fluid stops, replace the cap
on the open port.
TP10320APAGE 6
B. BLEEDING THE TUBING FROM THE
CONTROL VALVES TO THE NEEDLES
1 .Remove needles from the nozzles.
2 .To avoid spilling the fluid upon the folder, it is
recommended that you remove the nozzles
from their holders.
3 .Hold the nozzles away from the folder and
point them into a pail or absorbent rag to
catch the fluid when it leaves the nozzle.
4.Open the appropriate control valves.
5. THE PROPER NEEDLE FOR THE JOB
The WetScore is installeed with 23 guage needles. W e
have found that for most of the work that comes through the
shop these are sufficient. However , for heavy stock; 80 lb.
or greater; you may wish to use a bigger needle. Make sure
that the needles are not bent. Secure the needles in the
nozzles. The nozzles are internally threaded to fit the
needles, no tools are necessary. Insert the needles into the
nozzles and hand tighten, do not over tighten.
6. PLACEMENT OF THE NEEDLES UPON
THE STOCK
5.Hold your hand under the sensor to open the
on/off solenoid.
6 .Bleed the tubing until the fluid flows consis-
tently from the nozzle.
7 .It is customary for some air to remain in the
tubing after bleeding. This will usually not
affect the flow .
4.0 LOWERING THE PARALLEL UNIT
PIVOT ROD INTO PLACE
A. Make sure that the needles are not in the nozzles.
B. Lower the rod slowly to ensure that the nozzle
holders as well as the sensor do not sit upon the
shoe-in guides, register table sheet holddowns, or
side guide.
C. Snap rod into place on the support bracket.
A. POSITIONING OF THE NEEDLES IN
RELATION TO THE REGISTER TABLE
AND TAPE DRIVE ROLLER.
Adjustment is made by sliding the nozzle (needle
attached) in and out of the nozzle holder .
1 .The ideal location of the end of the needle is be-
tween the register roller and the plate of the register
table so that any drips from the needles will fall to
the floor and not build up on the register
table.
2 .Secure the needle nozzle in position within the
nozzle holder by means of the nylon set screw on
the side of the nozzle holder .
B. POSITIONING OF THE NEEDLE IN
RELATION TO THE PAPER STOCK
Adjustment is made by rotating the nozzle holder
about the pivot rod to the proper position on the
stock.
1.With the pivot rod down, run a sheet to be scored
under the rod until the registermark for the folder(or
a premarked scoring mark) is under the rod.
2 .Slide the nozzle holder with the needle in place
along the rod until it is over your mark.
3 .Rotate the nozzle holder down until the needle lies
on top of the mark and secure it in position by
tightening the nylon set screw on the top of the
nozzle holder . Hand tighten only .
4.When the needle is in the proper position it should
be touching the stock, with a slight downward
pressure. Do not lower it too far however as it will
retard the motion of the stock.
PAGE 7TP10320A
7.0 ADJUSTMENT OF FLOW RA TE
A. With the folder off, place your hand under the
sensor and open the appropriate control valve.
B. Watch for air bubbles in the tubing to move indicat-
ing flow from the needles.
C. Adjust control valves until the flow is greater than 2
drops per second from the needles.
D . If the proper flow cannot be obtained see TROUBLE
SHOOTING section of the manual.
WHILE RUNNING A JOB WITH
WetScore
1.0 CHECK THE FLUID LEVEL OF THE
BOTTLE
Never let the bottle run dry , unwanted air will fill the
lines. If the flow is sluggish, or signatures feel dry , fill the
bottle, the flow is gravity fed and dependent upon
presssure from the bottle.
2.0 W A TCH THE FLOW RA TE OF THE
NEEDLES UPON THE STOCK
8.0 POSITIONING OF PHOTOELECTRIC
SENSOR
A. The sensor is of the photoreflective type, it does not
require a “hole” under it to see through. Simply
position it over the sheet so that it does not interfere
with the side guide, shoe-ins, nozzle holders, etc.
B. Run one sheet under the sensor and watch to see if
the LED light on the sensor is lit when the sheet is
present, and off when not.
C. Adjust by rotating as necessary.
REFILLING THE BOTTLE
1.0 FLUID LEVEL OF THE BOTTLE
When refilling the alcohol/water solution in the bottle, it
is recommended that the bottle be only filled to 90% of
capacity.
2.0 BLEEDING AIR FROM THE TUBING
When the needle is on the sheet and the folder is
running, the line of fluid laid down by the WetScore should
approximate the size of the needle used. Check to be sure
that the needle is in constant contact with the sheet.
Do not allow space between the sheet and the needle.
The WetScore uses capillary action to pull the fluid out of
the needle by the motion of the stock underneath it. If the
needle is allowed to pour fluid upon the sheet, it will become
difficult to obtain a consistet flow and uniform score along
the sheet.
When the folder is running and the sheet gap is under
the needle, a drop of fluid should be visible at the end of the
needle prior to the next sheet running under the needle. A
strong flow may be desirable for heavy uncoated stock.
Signatures should feel slightly wet to the touch along
the scored edge.
3.0 CHECK THE LED INDICAT OR ON THE
PHOTOELECTRIC SENSOR
While the folder is running, the LED indicator light on
the photoelectric sensor should be off when there is no
sheet under the sensor. The indicator should blink on and
off with the sheet. If it is constantly on, raise the sensor
slightly to ensure that the solenoid will shut off when the
folder stops running.
When filling the bottle, always bleed the tubing between
the on/off solenoid and the control valves. Air may become
trapped in the solenoid and an inconsistent flow will result if
not removed.
It is usually not necessary to bleed the tubing to the
needles if there is adequate flow between the solenoid and
the control valves. For procedure see instructions above.
4.0 REMOVING JAMMED SHEETS
NEVER PULL SHEETS OUT OF THE FOLDER
WHEN THE NEEDLES ARE IN CONTACT
WITH THE SHEET. NEEDLES MAY BEND
AND YOU WILL LOSE YOUR SHEET REGISTER!
TP10320APAGE 8
When running sheets through the folder by hand,if it
becomes necessary to back the sheet out, always lift the
rod to ensure that the sheets do not jam into the needles.
They may cause the needles to bend and you will lose your
register!
OPERATING TIPS
1.0 WetScore IN COMBINA TION WITH A
MECHANICAL SCORE
If a sheet is under a needle or the sensor when the
folder stops, remove it before restarting the folder. It may
be wet and may cause a jam-up in the rollers.
5.0 WHEN THE FOLDER STOPS RUNNING
A. Remove the sheets from under the sensor and
needles so that the needles do not flow.
B . If the folder will be off longer that 10 minutes:
1 .Turn off the control valves to prevent air from
entering the tubing.
2 .Unplug the electrical cord(optional).
C . If the folder will be off less that 10 mins.,no need
to shut off the control valves.
NEEDLES WILL CONTINUE TO DRIP DUE TO
PRESSURE IN THE TUBING FOR SEVERAL
SECONDS AFTER THE ON/OFF SOLENOID
CLOSES.
WHEN YOU FINISH A JOB
A. Remove needles and place them in the holes on
the Amplifier housing support base for safety.
Due to the variable nature of the many types of stock
operators are forced to deal with these days, there is no rule
as to when to use a combination of mechanical scoring and
WetScore. We have found however, that for certain heavy
sheets, as well as cover stock, that the combination of the
WetScore with a mechanical score in the pull-out rollers of
the folder produces exceptional results. This is especially
true when using the WetScore to apply a score to the last
fold of a 16pg. signature. Many times the use of a mechanical score alone produces cracking or tearing of the signatures along the folded edge of the sheet. The addition of the
water/alcohol line from the WetScore should eliminate this
problem.
2.0 WetScore IN COMBINA TION WITH
PERFORATORS.
In many cases when folding 16 pg. or 32 pg. signatures
for the perfect-binder, case binding, or other subsequent
operations, it is desirable for the folded signatures to be as
flat as possible. Bundling devices are commonly used to
flatten the signatures after folding. We have found that the
use of the WetScore, in addition to the perforators used for
folding, produces signatures that are absolutely flat, usually
eliminating the need for bundling. Additionally the
WetScore greatly reduces the common problem of dogearred
corners when used in this way. The WetScore is not meant
to be a replacement for the use of perforations, rather an aide
to their effective use.
B. Unplug the WetScore.
C. Raise the pivot rod and secure it in the upright
position by use of the Velcro strap on the hanger
rod
D . Close all of the control valves.
E.The water bottle may hang full from its hanger
until needed for the next job.
3.0 WetScore ACROSS PRINTED
SOLIDS OR ALONG “BLEEDS”
Use caution when applying a WetScore wetted line
across bleeds or printed solids(i.e. reflex blue ink). The
interaction of the alcohol with the ink may cause the ink
vehicle to break down, producing offsetting along the folded
edge. This is especially common when running coated or
varnished stock. If possible, we recommend applying the
WetScore upon the opposite side of the sheet from any
bleeds or solids. Many times this can be accomplished by
changing the configuration of the folder set-up, i.e. by
running the job down in the second plate as opposed to up
in the first plate.
Additionally, applying a solution that contains less
alcohol will usually aide in preventing offsetting of the ink.
However, as the solution decreases in alcohol strength, its
ability to maintain a uniform line on the sheet also decreases.
PAGE 9TP10320A
The flow of fluid may also be adjusted by the control
valves to apply a minimum of solution to the stock.
If you do not succeed in reducing the offset by any of
the above means, we recommend that you do not use the
WetScore, proceed with conventional mechanical scoring of
the sheet.
4.0 WetScore WITH COA TED STOCK
The ability of the alcohol/water solution to absorb into
the sheet decreases with an increase in density of the sheet
coating. Hence the effectiveness of the WetScore decreases
as the sheet coating increases. The WetScore system is
designed primarily for uncoated work. We have found that
when used on coated sheets, the WetScore may prove
helpful in reducing the “cracking” that commonly occurs
along the folded edge of the signatures. Careful attention to
the flow rate of the needles when running coated sheets is
advised.
5.0 IMPORT ANCE OF HAVING A
SQUARE SIDE-GUIDE
One of the primary advantages of using the WetScore is
it’s capable of giving you absolutely straight scores that are
applied to the sheet prior to the sheet entering the fold
rollers. For this reason it is absoltely essential that the
register side-guide to be square to the fold rollers.
6.0 WetScore ON VER Y LIGHT SHEETS
For very light sheets, we recommend that the flow rate
of the needles be adjusted to a minimum. If the score
obtained is still not fine enough, we suggest using a smaller
diameter needle.
TP10320APAGE 10
MAINTENANCE
WEEKL Y
1 .Bleed all needle tubing.
2 .Using an air compressor, blow out any solids that may
have become trapped in the needles, i.e.-offset powder ,
paper particles etc. (remove needles from nozzles first).
MONTHLY
1.Tighten all support bolts on the brackets connecting
the WetScore to the folder rails, some loosening may
occur due to folder vibration. Bolts should be snug
with a wrench, do not overtighten.
2 .Check for sharply bent or highly worn needles replace if
necessary.
YEARL Y
1 .Replace all PVC tubing that seems brittle or abnormally
hard.
A. Use caution when removing the tubing from the
control valve ports as the tubing through use
will become slightly bonded to the brass. It is
recommended that you use an Exacto knife or
sharp blade to cut the tubing away from the
port. Do not attempt to pull the tubing off of
the port, damage to the control valves may
result.
B. Always replace tubing with the appropriate
type.
2 .Check for leaks in the control valves. Replace if needed.
