1. Set the foldplates to the proper open and closed
positions by rotating the stop blocks and placing
the correct symbol for either open of closed to the
position closest to the fold rollers. Then set the
desired fold depths using the scale on the belt and
reading at the yellow mark on the indicator.
2. Setup the slittershafts using the proper perforating
scoring or slitting accessories. If just a parallel
folder is being used an perforating, scoring or slitting
is not required, pullout tires must still remain on the
slittershafts to properly eject the sheets. Note that a
good setup procedure is to have all the setscrews
facing outward at the same clock position. This
eliminates a lot of handwheel turning to get to the
setscrews during job changes. See Fig. 51
3. Setup Delivery Stacker Wheels to the expected
position of the paper as it ejects the folder. The
independent speed control will need to be set during
the initial fold operation to insure proper shingling.
Note that the exit holddown straps must also be
installed to kick the sheet down onto the delivery
stacker.

Right angle Folding
When adding an 8-page or 16-page folder to a parallel unit
it is highly recommended that the stock must be either
perforated or scored as it exits the previous fold unit. The
perforating or scoring is to be performed at the line of the fold
that is to be folded in the next fold section. This weakens
the grain of the stock so that a consistent, quality fold can
be achieved. Perforating is also needed to relieve air that
can become trapped in the folding process and create
wrinkles in the paper. The size of the perforator tooth can
make a difference in the amount of air that can escape and
remove the wrinkle problem. Failure to score or perforate a
sheet going into a right angle folder will result in inconsis-
tent fold quality.
Refer to your operator’s manual for scoring, perforating
and slitting information.
Marbleholder Setup
Note that marble placement can be critical on some jobs
and not on others. You may want to remove some
marbles that are in the end that accepts the sheets at a
right angle so that the sheets do not bounce back when
trying to get under the marbles. At least (2) steel
marbles are recommended at the end closest to the fold
rollers to maintain sheet control against the guide.
