Introduction
Your Foldnak 40 bookletmaker uses the Foldnak principle: stapling and folding in one pass without
moving the sheets in between. This results in the staples sitting accurately on the spine. The
machine is intented to make booklets.
The operation modes are a) stapling and folding with Nagel staples 26/6, b) stapling and folding
with Nagel loop staples Ri 26/6, c) folding without stapling and d) corner stapling (Option).
Sets can be fed manually or automatically by a table top collator (optional). The Trimmer (optional)
can press the finished booklets and press the fold for flat laying booklets satisfying high quality
needs.

Accessories for the Foldnak 40
Nagel Online-Box
To be mounted below the feed table. The online-box features a transport belt to feed sheets in, a
tail jogger and electronic communication to table top collators and the Trimmer.
The online-box makes hand feeding more efficient. It is needed for bookletmaking online to a table
top collator.
The online-box allows to connect the following collators: Uchida UC-1000/800, Superfax
EC4500/4400, Horizon QC-P10/8, Duplo DC-10/8/6 mini, Plockmatic 310/306/410/406, MBM
Maxxum 6/10, Watkiss or A.B.Dick Vario (subject to changes).
The picture on page 2 shows connection to a table top collator (X2), which is on the Nagel Link
Stand HS (X1).
Nagel Link Stand H and HS
Stand on castors to connect table top collators. The type H is height variable (#285 8009). The
Type HS features an additional sliding table (#285 8010). The collator shifts sideways by turning a
hand wheel. This will save aligning the collator every time the sheet size changes.
Nagel Trimmer
Professional face trimmer for automatic online operation. Presses the booklet spine before cutting,
resulting in flat laying and precisely cut booklets.
Nagel stand for the Foldnak 40
Stand on castors with storage space (#240 0100).
Nagel belt stacker
The stacker features high capacity. By shingling the finished booklets taking away the finished
work is fast and easily done (#295 6600).
Nagel stapling heads
Supplementary stapling heads allow to use 4 stapling heads at a time. This will produce longer
lasting booklets when working with sizes bigger than A4 / 8 ½ x 11“.
Nagel tray & protection
To receive booklets and edge stapled sets (#2956539S)

Set-up for stapling and folding
Please keep to the suggested order.
Sheet width
Loosen knurled screw (A) and shift side lay (B)
according to scale on feed table.
A
Important notice:
Shift side lays only by holding the knurled screw
(A). Holding the side lay (B) itself will bend it.
B
Insert a sheet of the required size. Move right side lay
up to to the sheet, then draw back by 4mm to allow
the machine to side jog. Tighten (B).
A
B
Sheet length
Insert a sheet of the required size. Adjust the sheet
length by turning the hand wheel according to the
scale on feed table.
Belt stacker adjustment
Set potentiometer (13) to the „minus“ symbol for small distance between the booklets and to „plus“
for larger distance. From format size larger than 160 mm (e.g. A3 format 210 mm) the Foldnak 40
switches automatically to a fix distance in order to transport the booklet savely out of the machine
(avoid jams).

Automatic release
Loosen knurled screw (B). Push photocell (A) below the
sheets to be completely covered. Switch power on (16).
Pull photocell slowly back until machine fires. Fix
knurled screw (B) in that position.
A
The machine will now fire only if sheets are correctly fed
and aligned.
B
Manual release
If you wish to fire manually, unplug the photocell and push the switch (17).
How to widen roller gap
If your booklet is not e.g. properly transported
through the fold rollers or e.g. only the cover sheet is
being picked up when having a thick booklet with a
glossy cover sheet you may adjust the fold roller gap
for a better performance.
The gap between the fold rollers is usually adjusted
at 0,5 mm. By turning the knurled screw (A) counterclockwise you enlarge the gap between the rollers
and vice versa.
As a matter of experience we recommend to adjust a
gap of appr. 1 mm on thick booklets having glossy
covers.
Please do the adjustments parallel on both sides.
A
Folding without stapling
Draw the staple pusher backwards and get it catched in the back position. Take the staples out of
heads. If the heads will leave marks on sensitive paper, take them completely out of the machine.
Counter
The counter (15) keeps track of the number of finished booklets. Push the red knob to reset to
zero.

Error monitoring
The machine can recognise certain errors in order to minimise paper waste. The online-box
(optional) stops the collator in case of an error, and it will stop the Foldnak 40 in case of a collator
error. The machine will recognise the following errors, the red error light (14) will be on:
•
•
•
•
out of staples
Trimmer error (in case Trimmer and online-box are in use)
paper jam (photocell covered by sheets)
trailing edge of sheets not jogged correctly. As opposed to machines using a timer, your
Foldnak 40 will only fire if all sheets of a set are correctly fed and jogged. Also, if all sheets are
correctly jogged, the Foldnak 40 will fire immediately and not wait for the period defined by the
timer setting to pass.
Operator maintenance
•
•
•
Clean the fold rollers regularly to avoid marking of booklets by ink on the rollers
open the stapling heads and clean the staple channel with a dry, slightly oily cloth
have any other service work performed by an authorised technician

Trouble shooting
Machine will fire, stapling heads go down and stay there
• Put switch under the feed table into position II. The stapling heads will travel upwards.
Booklet jammed inside of machine
• Belt stacker plugged in? Otherwise finished booklets will stay inside of machine and cause a
jam.
• Turn potentiometer (13) towards „plus“ to make sure booklets will be transported away from
below the stapling heads.
• The green belt stacker transport belts will not run although belt stacker unit is plugged in: call
service technician.
• Finished booklet stuck between the fold rollers: Switch the machine off (16). Insert the supplied
5mm allen key into the right hole of the side panel (operator side). Turn clockwise to bring
booklet out. Pull the key out.
• Check if, after stapling is finished, the fold rollers stop in a position to let the stapling heads
push through the cut-out in the fold rollers. Otherwise call service technician.
Stapling heads jammed in down position:
• Close the cover (1) in order not to cut the power supply.
• Put switch under the feed table into position I = SERVICE.
• Insert 5mm allen key into the left hole of the side panel (operator side). Turn counter clockwise
to bring the stapling heads up.
• When the stapling heads are in their up position the machine will block them automatically. Put
switch under the feed table back into position II. Pull the key out.
• Check if, after stapling is finished, the fold rollers stop in a position to let the stapling heads
push through the cut-out in the fold rollers. Otherwise call service technician.
• Potential causes: Sheets jammed between the fold rollers and stapling heads. Check if fuses
have blown (besides the socket for the belt stacker).
Staples jam
• Check that you are using Nagel 26/6 staples or Ri 26/6 loop staples.
• The engraving „26“ in the driver bar must face the operator.
• Check if the driver bar is hooked onto its pin and the knurled screw is tightened.
• Replace driver bar if showing signs of wear or bent.
• Open stapling head and clean staple channel out with a dry and slightly oily cloth.

Machine will not fire
• Is the wall socket under power?
• Power cord fully plugged into wall socket?
• Power cord fully plugged into machine socket?
• Machine is switched on (16)?
• Is the cover (1) closed?
• Is the photocell plugged in?
• Pull the photocell slightly away from the sheets‘ trailing edge to make the machine fire more
safely
• Red error lamp (14) is on: Out of staples? Check the Trimmer.
Sheets will not run into machine easily
• Set the side lays to wider sheet width.
• In many cases the online-box (optional) will improve feeding and make it more safe.
Staple not on the spine, fold out of angle
• Set the side lays to wider sheet width. The machine requires 4mm of play in order to be able to
jog the sheets up. If side lays are set too narrow the sheets will be squeezed, leading to
inaccuracies.
• Set the side lays up narrower in order to have an exact side jog.
• Have all sheets been cut squarely?
• Do all sheets have an identical width?
