2. APPLICATIONS
1. The Neschen laminator for large formats is suitable for the application of
laminating and carrier foils by pressure or heat on large format prints, plates,
boards and similar products up to a width of 1650 mm.
2. Although the laminator is designed for large formats it can also be used for
laminating smaller formats starting from A5.
3. The laminator design allows unlimited length of laminated prints.
4. When processing larger formats (larger A0 or corresponding to the maximum
working width of the machine) additional support by another person is required.
5. The flexible use and easy handling of the Neschen Laminator allows working
with cuts and rolls. The user chooses the appropriate laminating technology, e.
g. sheet lamination or laminating from roll or reel to reel.
6. Any changes made to this laminator without the manufacturer’s permission will
relieve the vendor from its liability for any damage or injury!
7. If the laminator’s features allow the device to be used for other purposes not
listed here, the user must consult such applications with the vendor.
8. Follow the safety precautions while working on the machine to avoid personal
injury or injury to bystanders.
9. Notes which require special attention are marked with the following safety
symbol in these operating instructions:

6. CONTROL PANELS – RIGHT
Emergency STOP button – Function is identical to that of the left control panel
The upper roller can move up and down with distances from 0 to 40 mm.
Note: The height adjustment only works if the direction of rotation, forward or
backward, has not been selected (the direction button does not light up). The height
adjustment is controlled by the following buttons:
down – the top roller moves downwards. The key must be held down. When
released, the roller stops immediately. If the upper roller touches the material or
the lower roller, it stops automatically, a warning signal sounds and lights go on
and the machine cannot move further down - only an upward movement is still
possible. If a light barrier is interrupted during downward movement, a warning
signal sounds but the roller moves further downwards.
up – The top roller moves upwards. The key must be held down. When released,
the roller stops immediately. As soon as the roller reaches its maximum height of
40 mm, it stops automatically and can only be moved downwards.
Roler rotation – the lower roller is driven by an electric motor. With the ColdLam,
the revolutions can be controlled continuously in the range from 0 to 8 m/min and
the HotLam in the range from 0 to 12 m/min.
Rotary knob for rotation – Potentiometer for speed control. The desired speed is
set in meters per minute.
run – roller rotation for forward movement – The direction of rotation is indicated
by the corresponding key light. The Neschen laminators have a modern,
intelligent start function that allows the laminator to be started slowly and evenly
until the speed set by the rotary knob is reached. The speed does not depend on
the load. Note: If the roller speed is set to 0, the laminator does not start up but
waits until the operator sets a speed other than 0.

If the machine is equipped with a footswitch and this is operated, the machine works in
run direction with a speed of 1m/min and a signal tone is on. Light barriers are ignored.
slow – The rear panel works in the same way as the footswitch. When activated,
the machine moves in run direction at a speed of 1m/min with a signal tone. Light
barriers are ignored in the process.
rev – Adjustment of the rollers in backward movement (same functions as
forwards movement)
stop / settings – stops the rotation and the run direction. If the light barrier is
interrupted while the machine is running, a signal sounds and the machine stops.
Note: If the operator changes the direction of rotation while the machine is running,
he must first press the stop button and then select the desired direction of rotation.
stop / settings – keep the button
pressed for 3 seconds to get to settings
The first menu item is the temperature
setting. The desired setpoint
temperature is set by pressing the UP /
DOWN buttons. Pressing the STOP
button saves the setting and the user
gets to the next menu.
The next menu item is the meter
counter. If the user wants to set it to
zero, one of the UP / DOWN buttons
must be pressed. Press the STOP
button to get to the next setting.

In the countdown menu, the machine
can be given a fixed meter value in full
meters. The machine then stops
automatically after the length has
elapsed.
Important - to produce again without
automatic stop, the value in the menu
must be reset to zero.
BUTTON FOR PRESSURE REGULATION – to adjust the pressure of the main roller. In the
lower position, the pneumatic system presses the main roller downwards with a
force of 1000 to 4500N. In the upper position, the pneumatic system automatically
reduces the pressure of the main roller to 500N.
As standard pressure setting for one-sided coatings (print and film) 1.5 bar (+- 0.5
bar) should be used.
7. SILIKON PAPER AND LAMINATED PRINTS
Shaft rotation – the shafts for silicone paper and laminated prints (end products) are
driven by electric motors. The machine synchronizes their revolutions with the
rotational speed of the main rollers. The resistance on all shafts can be changed by
turning the brake. The stronger the brake, the greater the resistance of the shafts
and vice versa.
8. FUSES AND FOOTSWITCH CONNECTOR
The Neschen laminators have three fuses. Their parameters and how to replace
them is described in the Maintenance & Repair section.
9. ROLL CARRIER/SHAFT
Laminating and printing materials are rolled up on a paper tube with an inner
diameter of 76.2 mm. The shafts of the Neschen Laminator are designed for these
tubes.
If the material is unrolled too loosely or too tightly, the braking force can be adjusted
by applying or releasing the brake on the right-hand side of the machine. By
applying the brake, the braking force is increased and by loosening it is reduced.
The resistance of the shaft can be adjusted by adjusting the clutch on the righthand side if silicone paper is not wound, or too tightly or loosely.

10. APPLYING A MATERIAL ROLL TO THE SHAFT
1. Remove the shaft from the laminator. Shafts are attached to the right side of
the laminator. Turn the carrier until the lock is released. The positions for
material underneath the feed table are secured with a twist lock. Before
removing the shaft, loosen the lock. First remove the shaft located on the side
of the lock.
2. Insert the roll of material into the shaft. Heavy rolls should be loaded by two
persons.
3. Reattach the shaft in the machine by carrying out the procedure from point 1
in reverse order.
