And other parallel folds And other cross folds
Small folded sheets can be stacked
vertically by the optional standing
delivery. The stack can also be offset.
Cross folding can be done by using
the optional KTU-35 Cross Folder.
The folding
operation can be
stopped after a
predetermined
number.
A stack offset can
be performed after
a pre-determined
number.
The folder has four buckle plate, so various kinds
of parallel folding can be performed.
With the optional KTU-
35 Cross Folder, cross
folding is available.
The gaps between the fold rollers can be
adjusted easily.
The sheets are fed from the
bottom. More sheets can be loaded
while the machine is folding.

mechanism allows the unit
to feed coated stock.
The minimum folding
length is 20 mm
(0.8").

2-2 Check the Fold Pattern
Check the settings by referring to the table.
(1) Determine the fold pattern.
- The EF-354 can do parallel folding.
- The EF-354 can create various folding patterns by setting the buckle plate and gap adjusting levers in
various ways, although the table below shows only the general folding patterns.
(2) Determine which buckle plate to use.
(3) Check the position of the stopper on each buckle plate.
- The table shows the stopper position in relation to the sheet length.
(4) Check the number of the sheets to set in the gap adjusting levers.
- After checking the setup table, go to the sections on “Setting the Buckle Plates” and “Setting the Gap
Adjusting Levers,” and perform the setup operations.
The following table indicates the setting of buckle plate and gap adjusting lever according
to the fold pattern. Check this table before setting the buckle plates and gap adjusting
levers. See section 2-3, “Setup Details.”
- The position of each fold depends on the position of the stopper.
- The fold pattern depends on the buckle plates being used.
- The gap between any pair of fold rollers can be adjusted using
the gap adjusting levers.

Setting the buckle plates
See the table in section 2-2 to determine
which buckle plates to use, and where to set
the stoppers.
Set each buckle stopper.
1) Measure the sheet length.
- Use the scale next to the panel.
2) Calculate the stopper position.
- See the tables on pages 12 and 13 to calcu-
late the stopper position.
3) Open the soundproof buckle plate covers.
In order to remove the fourth buckle plate, remove the
second buckle plate first.
4) Pull out the buckle plate.
- Each buckle plate can be pulled out by
loosening the locking knobs on the front and
rear covers.

each gap adjust lever. See column 4 in the
table on pages 12 and 13.
Set the gap adjusting levers.
1) Pinch the sheets using the gap adjusting
levers, referring to the tables on pages 12 and
13.
- Use a sheet which is identical with the sheet
being folded.
- Each roller has gap adjusting levers on the
front and rear covers.
Insert the sheets completely to the end of each gap
adjusting lever.
- There is a hexagonal hole on the stopper locking
screw. Tighten this using an Allen wrench to set the
stopper.
- If the stopper is in a position which makes it difficult
to move, remove the buckle plate from the main
body and adjust the stopper position.

Setting the gate plate
The gate plate allows the machine to feed
only one sheet at a time. In order to prevent
double feeding or misfeeding, adjust the gate
plate properly.
Set the gate plate.
1) Adjust the gate plate.
- Loosen the slide locking screw and move the
gate plate to the left for thin sheets, or to the
right for thick sheets.
- Set the gate plate to the left side of the center
of the feed rotor. (See the drawing below.)
Do not move the gate plate too much to the left. Other-
wise, the sheet might be creased by the edge of the gate
plate.
2) Adjust the height of the gate plate.
- Insert two sheets between the gate plate and
the feed rotor.
- Turn the up/down adjusting knob to set the
gate plate so that two sheets can be pulled
out tightly, but a single sheet can be pulled
smoothly.
Extension Table
Setting the feed table
Load the sheets on the feed table.
Load the sheets on the feed table and set
the feed guides to the edges of the
sheets.
- Put the sheets in the center of the table using
the scale.
- Set the feed guides so that the feed rotor comes
to the center of the sheets. Loosen the locking
knob to move the feed guide.
- Set each feed guide so that the gap between the
feed guide and the sheets is 1 mm (0.04”) or
less. Check that the sheets have no play and
move smoothly in the directions shown by the
arrows in the figure below.
If you are using sheets which are longer than the feed
table, attach the extension table.
