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. 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.
5. THE PROPER NEEDLE FOR THE JOB
The WetScore is installeed with 23 guage needles. We
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
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.
