4.1 Slat conveyor
These axle brackets on both sides of the
slat conveyor are to be swung into a
vertical position and, after loosening
the knurled screws, then secured. When
not in use, the axle with the transport
wheels can be taken off, the axle
brackets folded towards the bottom and
the slat conveyor can be folded upright
and locked in order to save space.
The slat conveyor (fig001, 3) (option
with Foldnak 4) is folded upright for
transport and locked with a hook.
Raising the hook unlocks it and swings
it into an approximately horizontal
position. In this position the rod (11) is
guided into the hole of the foot stand as
a prop. The rear collecting plate (13) is
then hung downwards at an angle.
The axle and both wheels (10) are
accessories. They must be pre-mounted
with the set collars, which are also
accessories, so that both wheels are
exactly over the green conveyor belts
when the axle lays in the long vertical
slits of both axle brackets (12).
5 Preparation
5.1 Stapler heads / Stapler head
Foldnak stapling-folding machines are
delivered with two stapler heads as
standard. They can be operated with up
to four stapler heads. The possible
stapler head positions are:
Foldnak 8
Foldnak 6
Foldnak 4
Distances in mm
30 x 50 x 80 x 50 x 30
30 x 50 x 80 x 50 x 30
50 x 80 x 50
The driver (20) is re-set as described in
Chap 8.2. By adjusting the stapler
heads and simultaneous adjustment of
the side stops, the position of the
staples in the paper can be altered. Care
must be taken that the stapler heads are
not placed over the side stops,
especially when the stapler heads are
used in the outer positions. Finally,
plug the contact cable (19) onto the
contact bank (18).
The stapler heads can be adjusted in the
previously given positions. For this, the
screws (21) behind the stapler head
batten (22) must be unscrewed with the
supplied hexagonal spanner, the stapler
head must be put into the desired
position with the spigots and screwed
tightly again.
5.2 Staples
5.3 Inserting staples
Foldnak stapling-folding machines use
the following Nagel-staples:
In order to insert staples, first of all the
staple slide (26) is to be pulled back
with the index finger on the underside
of the stapler head magazine until it
• 26/6
26 = Wire guage
6 = Shank length in mm
for 2 up to ca. 20 sheets
• 26/8 S
26 = Wire guage
8 = Shank length in mm
S = Steel wire
for 15 up to ca. 40 pages
• Ri 26/6
Ri = Ring staples
26 = Wire guage
6 = Shank length in mm
for 2 up to ca. 20 sheets
Only use original Nagel staples. They
are made with special precision and
therefore guarantee problem free and
accurate function.
We can only honour the staple head
guarantee when Nagel staples are used.
Then swing back the magazine cover.
Insert the staples in this position. The
magazine holds a stick of 210 staples or
ring staples. When changing staples,
check that no staples of the old type
have been left in the magazine. Then
the magazine cover is to be closed and
the staple slide guided forwarded with
the thumb and index finger. Do not let
it shoot forward too quickly otherwise
the staple stick breaks.

the block stapling stop in position 1.
(29) Rotary button for the slat
conveyor. Controls the separation of the
brochures on the slat conveyor (see
Chap. 6.5.7, only Foldnak 8).
6.1 Control panel
Foldnak 6 und Foldnak 4 do not have
the switches (30) and (29).
6.2 Magazine control
The Foldnak is fitted with a magazine
control. When there are not any more
staples in the staple magazine, the
machine does not trigger. This state is
indicated by illumination of the red
signal lights (36) on the control panel if
the contact cable (fig003, 19) has been
The Foldnak 8 control panel is laid out
as follows:
(36) Red signal light. It illuminates
when the staples are finished or
jammed. The machine can not trigger
any more.
(35) On - off switch.
(34) Numbers counter with reset button.
(33) Service switch wide. In position 1
it serves as a brake lifting switch for the
stroke motor brake.
(32) Service switch narrow. It serves as
manual release. The photo-cell must be
pushed out for this.
(31) Folding rollers on - off. The rollers
must be switched off for block stapling.
6.3 Staple error control
6.5 Stapling brochures
The foldnak is equipped with a staple
error control. The staple error control
stops the machine triggering when there
is a staple jam in the stapler head. In
this condition the driver jumps out of
its suspension and touches the spiral
contact (fig003, 15). This causes the red
signal light to illuminate. Then the
driver has to be hung again after any
stapler remnants have been removed
from the stapler head (see chap. 8.2 and
6.5.1 Formats / Number of sheets
Paper formats from 140 x 210 mm to
325 x 450 mm can be processed in the
Foldnak stapling folding maching. This
includes for instance DIN A3, A4 and
The number of sheets which can be
processed in a brochure is dependant
upon the thickness of the paper and the
cover. Dependant upon the paper
quality ca. 30 sheets of 70g paper or 25
sheets of 80g paper can be processed
for brochures with 120 or 100 pages.
When a cardboard cover is used then
the number of sheets is to be reduced
6.4 Equipment control
The Foldnak is equipped with an
equipment control. It stops the stroke
triggering when the paper has not been
laid in correctly. The equipment control
only works when the trigger has been
correctly adjusted (see chap. 6.5.4).
6.5.2 Adjustment of the side stop
Then adjust the right stop.
First of all adjust the side stop with the
assistance of the scale (38) on the green
table plate. To do this the knurled screw
(39) is opened and the stop moved to
the side.
To do this, insert a sheet of the paper to
be processed and, after opening the
knurled screw (41), the right stop is
then brought flush to the sheet. From
there, move ca. 4 mm to the right and
secure the side stop in this position.
This guarantees that the jogging
movement which has been built into the
right side stop, and is ca. 4 mm, lines up
the staples smoothly.
After correct adjustment the knurled
screw is again tightened.
6.5.3 Adjustment of the rear stop
6.5.4 Adjustment of trigger
Adjustment of the rear stop is carried
out by the turning handle (4, fig001) on
the left side of the machine (only
Foldnak 8). For adjustment a sheet of
the paper to be processed is inserted.
The turning handle is then moved so
that the upper edge of the paper aligns
with the format mark (for DIN formats),
which correponds to the paper format
on the scale on the equipment table.
Adjustment is carried out when the
machine is switched off. Under the
Foldnak work table is an adjustable
photocell which has a baffle plate (48)
mounted upon it.
• Switch off Foldnak.
• Insert a sheet of the format to be
• Loosen screw (49) and push the
photocell under the sheet.
• Switch on Foldnak.
• Pull the photocell slowly back until
the Foldnak triggers. Then tighten
the screw (49) in this position.
With Foldnak 6 and Foldnak 4, open
the guard plate (43) and lock it
upwards. Then move the rear stops (44)
after opening the knurled screw (45).
Correct adjustment of the rear stop is to
be checked by a trial stapling.
6.5.7 Adjustment
The switched-on machine now triggers
automatically when the paper has been
correctly inserted.
In order to be able to optimally utilise
the capacity of the slat conveyor
(fig001, 3), brochure movement on the
slat conveyor is adjustable (only
Foldnak 8). The movement, i.e.
overlapping of individual brochures on
the slat conveyor, is adjusted by the
rotary switch (fig005, 29).
The baffle plate has the function of a
barrier, it prevents single sheets
jumping back.
6.5.5 Triggering by hand
Triggering can be carried out by hand
when desired. For this, the photocell
plug (fig009, 47) must be removed. The
stroke is triggered by pressing the
switch (fig005, 32) on the switch panel.
The distance of the Foldnak
suppression wheels is also to be
adjusted. For this, adjust the axle
brackets (fig002, 12). A rule of thumb
is that for small formats the wheels
have to be closer to the Foldnak and
further away for larger formats. The
individual optimal adjustment is to be
ascertained for a brochure.
6.5.6 Counter
The counter on the switch panel can be
re-set to zero by pressing the red switch
whenever work is started. The number
of brochures produced can be seen on
the counter.
6.5.8 Stapling
6.6 Stapling blocks
After switching on the machine, the
paper is laid onto the equipment table.
When is is correctly inserted, triggering
occurs automatically. Should the paper
not be correctly inserted, i.e. the upper
edge of a sheet does not cover the
photocell, the paper can be smoothly
pushed by hand through the wide slit in
the middle of the equipment table.
This task becomes unnecessary when
you use a vertical vibrator (see chap.
The first stapling should be a trial
stapling to check the adjustments. The
staples should be located an equal
distance from the upper and lower
edges of the brochures, sit exactly in
the fold, and the fold should be exactly
in the middle of the format. If necessary
adjust the stops.
6.6.1 Formats / Number of sheets
The maximum number of sheets when
stapling blocks is approximately as
follows according to the paper weight:
Paper weight:
Foldnak 8
Foldnak 6
Foldnak 4
55 sheets
40 sheets
40 sheets
40 sheets
30 sheets
30 sheets
Depending upon how the paper is
inserted, stapling can be, for instance, a
staple in the upper left corner (corner
stapling) or two staples at the side
(block stapling). The distance to the
edge of the paper is fixed, and is ca. 5
mm. Adjustment of the side stops and
triggering is the same as that of
brochure stapling (see chap. 6.5.2,
6.5.4). Do not use the format marks on
the scale under the work table when
adjusting the rear stop.
6.6.2 Block
Foldnak 8
Re 3.) Decouple the folding knife:
With the Foldnak 8, blocks can be
stapled in the form that the block is
automatically laid out on the slat
Changing to corner or block stapling:
1. Switch off the rollers
(switch fig005, 31)
2. Switch on the block staple stop
(switch fig005, 30 on position I)
3. Decouple the folding knife
4. Adjust the slat conveyor
When the machine is switched off, the
folding knife is decoupled by
unscrewing screw (52) with the
supplied 4 mm hexagonal spanner. The
screw must be completely unscrewed
and removed. Two holes for keeping
the screw and hexagonal spanner are
located on the right in the cubby hole of
the front plate.
Carry out these steps in the reverse
order in order to switch off block
After again changing to brochure
production, the screw (52) must be
completely screwed in again. It moves
during operation and would otherwise
break off.
By adjusting the support (57) the slat
conveyor is folded at an angle
downwards. The collecting plate (55) is
folded upwards and retained in this
position with both knurled screws (56)
to the right and left of the slat conveyor.
Re 4.) Adjust the slat conveyor:
Both transport wheels are inserted into
the upper position of the axle brackets
so that they somewhat brake the block
that falls out.
The jump angle (54) is raised and
pushed a little to the right or left, so that
it supports itself on the slat conveyor. It
prevents the block slipping down into
the gap between the slat conveyor and
the machine.
The strap (60) is then taken off after the
screw has been loosened and both of
the rear stops (59) are unscrewed so
that the block can fall out of the
machine after stapling.
6.6.3 Block stapling with Foldnak
6 and Foldnak 4
When guiding the stop, push the
moving arm up in the direction of the
arrow (fig013, 67) and at the same time
push the stop in the direction of the
arrow (fig013, 66). It then clasps the
lower roller. It is important for the
correct seating that the stop groove is at
the position (fig013, 64) under the rear
wall plate.
For block stapling the rollers must be
switched off by the switch (fig005, 31)
on the switch panel. Then pull out the
photocell plug (fig009, 47). Triggering
is done by hand by using the switch
(fig005, 32) on the switch panel.
When the stop is fitted, the paper can be
inserted in the machine from the front.
It knocks against the position (fig013,
63). After stapling, the paper can be
removed by hand.
The supplied block stapling stop
(fig013, 66) (accessory for Foldnak 4)
is necessary for block stapling. The
additional stop is to be guided into the
long slit in the rear wall underneath the
rollers. Thereby hold the smooth side of
the stop parallel to the rear wall. Fig013
shows the correct position of the stop.

Then tighten the knurled screw. When
changing the driver, care is to be taken
that the engraving “26” on the upper
end of the driver shows towards the
operator. Normally Foldnak stapling
folding machines are delivered with
ring drivers (item no. 2932619) which
are suitable for stapling with ring
staples or staples. Instead of the ring
driver, a flat driver (item no. 2932616)
can be used for thick layers.
8.3 Stapler
Then replace the stapler head and
tighten the knurled screws (24). Staple
remnants in the guide channel can lead
to driver breakage. Please, therefore,
thoroughly clean the guide channel
every time stapling is unsuccessful.
Very thinly grease the driver above the
stapler head after approximately ever
5,000 staplings.
Clean the stapler head regularly,
otherwise faulty operation could occur
because of dirt.
Should there not be any staples in the
paper although the magazine is full:
Check whether the staple slide is bent
forward due to accidentally being
allowed to spring forward. If this is the
case then carefuly file off these burrs so
that the staple slide can again push
completely forwards into the stapler
Damaged staples must be removed from
the stapler head staple channel. For this,
pull back the staple slide (fig004, 26)
until it engages, then loosen both
knurled screws (fig004, 24) and swing
the straps (fig004, 27) towards the
8.4 Cleaning rollers
With use, printer’s ink can collect on
the rollers. This can reduce the rollers’
grip. For this reason the rollers must be
cleaned when needed. A cleaning agent
can be used for this, such as is used for
folding machines or pressure rollers.
The stapler head can be pulled off after
the contact wire has been pulled off.
The stapler head front plate and the
magazine are to be cleaned of staple
remnants as well as the front plate still
in the machine.
8.5 Rotating the machine by hand
