1. Adjust the feed table squaring screw and align the center line of the
scaled tie bar with the center mark on the feeder table (Fig. 13).
Figure 14
2. Position the feed table side guides using scales on front and rear tie
bars (Fig. 13 & 14). The scales are set up to center the paper over the
vacuum wheel. Set the front of the guide first (Fig. 14) then the rear. Set up
the opposite guide the same way making sure forms slide easily the length of the
fed table without binding.
3. Remove roller guard (Fig. 14).
Figure 15
4. Place a couple of collars or a type bar against the roller (Fig. 15). Back
off sheet separator and slide the piece of paper under separator and up against
collars or type bar. Watch carefully as the paper strikes them.
5. Now, adjust feed table squaring screw (Fig. 13) so that sheet strikes
collars or bar at exactly the same time. Your feed table is now set up to
deliver forms squarely into rollers.
6. Remove collars or type bar and replace roller guard.
VACUUM FEED SHEET SEPARATOR
You will need to adjust the sheet separator for the type of forms you are
feeding. Ideal adjustment will feed only one sheet without putting any drag on
the paper. In general, use the following procedure to adjust sheet separator.
You will have to fine-tune these adjustments according to your forms and
environmental conditions of your particular work area. Refer to illustration and
photograph(s) for part identification.
Figure 16
System Adjustment:
1. Raise sheet separator by turning adjusting knob and insert one (1) of your
forms between vacuum wheel separator (Fig. 16 on previous page).
2. Lower separator until paper binds then back it off slightly.
Figure 17
3. Turn on the main power and the compressor motor. Keep roller motor turned off
- all setup adjustments will be made with the handwheel. Shut all air blast
control knobs on the side guides, Fig. 17, while adjusting vacuum.
Figure 18
4. Vacuum is set at factory. There is a bleeder valve on the vacuum pump (Fig.
18) which allows some adjustment. General Settings for the bleeder valve are
half open for 20# stock, and closed for 80# and heavier stock.
5. The positions of the sheet separator and the vacuum advance, ill. 3, are set
according to the weight of forms being folded.
ill. 3
For heavy stock (ill. 3, position 1), loosen the sheet separator lock knob
(Fig. 17), and position separator close to the top of vacuum wheel, for medium
to light stock (ill. 3, position 2), set the separator farther away from the
lift. Adjust vacuum advance to match the position of sheet separator.
Figure 19
6. The vacuum advance knob on the side of the feed table (Fig. 19), moves the
position of the vacuum on the feed wheel, ill. 3 & 4. Raising the knob
will move vacuum position away from the lift of paper and lowering the knob
will position vacuum closer to the lift of paper.
ill. 4
Vacuum position should be set slightly in front of sheet separator. If vacuum
position is set too far forward, the edge of the sheet might be pulled into the
slot of the feed table, causing misfeeding and tick marks on leading edge of
sheets - reposition vacuum advance to eliminate tick marks and provide smooth,
continuous feeding.
7. With vacuum pump on, calibrate your sheet separator to feed just one sheet
at a time. Load 2 or 3 sheets of your stock on feed table and feed them
through separator, using the handwheel to check double feed, gap between
sheets, and tick marks.
8. Load forms onto the feed table and attach the back stop to the side guide.
Forms should be no higher than side guides.
9. Begin adjusting air by turning out the control knobs. Air should be
adjusted to separate the bottom of the stack approximately 1/8" (3 mm).
10. With speed control all the way down, turn on roller motor. Gradually turn
speed control up to feed a few sheets. Check for double feeds.
Controls mentioned above contribute to smooth continuous feeding, there are
many possible combinations. Depending on humidity and type of stock, they will
have to be fine-tuned as you run your job.
11. Adjust sealing water in the same manner as with continuous sheet operation
(pg. 8).
12. Check water applicator clearance in same manner as with continuous sheet
operation (pg. 8).
FOLD PLATES
Plate setup will depend on type and position of folds you require. Fold plate
design on machine will allow up and/or down folds and quick changes without
removing plates to change from open or closed deflector positions.
A good understanding of the roller/plate configuration will help you decide
which plate to open or close for up or down folds. Illustration 5 shows paper
path for a common Z-fold.
ill. 5
A self adhesive folding guide label is included with the manual and may be
placed on the delivery tray. Used along with scales on the fold plates, the
guide will help you quickly set up for some of the most common folding jobs.
Initial coarse adjustments are made with lock screws on plate stops.
Figure 20
Fine adjustments are mad with micro adjust knobs on the ends of fold plates
(Fig. 20). Set up coarse adjustment then feed a sheet with the handwheel to
check the squareness of your setting. Square the fold stops to your paper with
the micro-adjust knobs. Additional fine-tuning can be done when folder is
running.
Figure 21
For easy access to the second fold plate, the feed table may be swung up out
of the way and held there by inserting the holding pin in the side frame (Fig.
21).
STACKER
Figure 22
1. Install stacker table assembly (Fig. 22). Insert spring-loaded, (right side)
of the table first, compress the spring against the side frame and pop opposite
end into position in the left side frame.
2. To pile folded materials, the stacker tray may slide in or out. Loosen lock
knob underneath tray and adjust as desired (Fig. 22).
Figure 23
3. Attach stacker wheel assembly to tie bar, as shown (Fig. 23).
Stacker consists of a table, belts, wheels, stacker springs, and a delivery
tray. The stacker accumulates and seals folded forms for easy removal and
stacking. Springs and stacker wheels keep delivered sheets from opening up,
interleaving and creating paper jams.
Set up:
1. Set stacker wheels back from the scorer shaft the width of the folded sheet
plus an additional 1/4".
2. Wheels should be centered over glue strips of the folded piece to seal as
it is ejected from the slitter assembly.
3. Position the stacker springs on the scorer shaft tie bar. They should be
positioned towards the outside of the sheet to hold the edges of the folded
piece down (Fig. 23 & 24). Springs may be bent for best operation.
4. Depending on the type of fold, best stacking performance may be had by
using only the springs or only the stacker wheels. Fine-tune these adjustments
as you run your job.
CLEANING
A clean machine will reflect in the quality of the work it produces. As you
unpack your folder, wipe off any excess protective oil, dirt, or dust which may
have accumulated during shipping.
Keep your machine clean, and wipe off any accumulations of paper dust at the
end of each day. Cover your machine anytime it is not in use. See maintenance
section for additional cleaning instructions.
