Job Setup
12. 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.
13. 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. 7
14. 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 inconsistent 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.
