SETTING FOLD PLATES AND DEFLECTORS Continued….
(step 4 continued)
thousands. THINK BEFORE YOU MAKE A MOVE. If you don’t, you can spend hours
doing something you could have done with one move. If someone has removed the plate
rails from the folder, start with the high point of the eccentrics in the center and pointing
toward the fold rollers.
5. After you have the fold plate properly adjusted, adjust the guide screws on the fold plate.
This is not a critical adjustment. It should be about .040 of an inch. Replace the plate
clamps and the plate stop you removed and straightened when you removed the fold
rollers. Leave the bolts loose until you adjust the deflectors.
6. Pull the fold plate you finished adjusting back and install the proper deflector gauges
(using either Appendix B or C) with the thick part of the gauge up in the same location
you placed the plate gauges. Lower the deflector in place. Lower the fold plate assembly
against the deflector gauges. Scribe a line on both plate rails at the back of the fold
plate. Remove the deflector gauges and fasten the fold plate with the plungers or gear or
plate latches. The fold plate and deflector should be on the scribe line. The only one you
can change between the fold plate setting and the deflector setting is the 700 series with
the plate latches. Now, again using either Appendix B or C, use the proper feeler gauge
to set the proper distance between the top of the deflector and the fold roll above it. On
the 200 series and the earlier 700 series you can use a flat feeler gauge and hold it
parallel with the top of the fold plate assembly to check the distance between the fold
plate and the fold roll. The adjustment screw to raise and lower the deflector is in the
hinge of the deflector. This is a critical adjustment. If it is too low, you will get dog-ears
(corner of the sheet turned back). If it is too high, the deflector will rub the fold roll. Once
you have the proper setting, tighten the nut on the adjustment screws so the setting will
not change. Now move the plate stop so it clears the stop on the deflectors
and tighten
the bolts. The plate stops are there so when you lower the fold plate when the folder is
running, the fold plate will not hit the roller. THE 700 SERIES WITH THE FOLD PLATE
LATCHES ARE ADJUSTED THE SAME WAY EXCEPT A FEELER GAUGE WITH A
BEND ON THE END. This is due to the shape of the deflector. You want to feel the
space between the top edge of the deflector and the roll. The only way this is possible is
with a feeler gauge that will not touch the back edge of the deflector.
7. Continue the same process with the number two, three, and four plates and deflectors.
8. Replace the gears and belts on the outside of the frame except the drive belt on the
register table.
9. Replace the register table and drive belt on the register table.
10. Replace the bushings, if necessary, in the slitter shaft boxing. Ream each one with a
7/8” reamer. Mount the boxing with the slitter shafts and line ream from the left to right
and right to left. Install the slitter shafts
