Operating instructions

Roller up/down and roller pressure

Setting pre-pressure and nip opening when processing panels

Example: Mounting print at recommended pre-pressure of 1.00 N/mm.

Panel thickness 10 mm.

1. Set pre-pressure to 1.00 N/mm, it is recommended to turn knob clockwise to set the pre-

pressure.

2. Rotate the hand wheel clockwise to move the top roller down for the needed nip setting, until

the nip setting display [13] shows a value of 10.0mm. It is recommended to move the top roller

down to set the nip opening.

3. It is recommended to carry out a nip pressure test as follows:

a. Place panel in front of rollers.

b. Start the rotation of rollers in forward mode and push the panel into the nip.

c. The display of the nip opening will change and show the motor current in Amps

(i.e. A0.5

)

d. Stop the rotation of the rollers when the panel is about 50mm ( 2 inches ) into the nip.

e. The display of the nip opening and pre-pressure will change to a higher value, do not

worry and do not adjust anything. The increase shows that the pre-pressure has been

reached.

f. The display shows the current nip pressure. If the value does not change, the thickness

of the panel may be to less. Move the roller down by rotation of the hand wheel until

the pre-pressure value increases 1-3 digits.

g. If necessary, the nip pressure can be reduced now. Use the hand wheel for moving up

and down the roller to adjust. The nip pressure value during process must always be at

least 1-3 digits higher than the set pre-pressure.

h. Start reverse rotation of the rollers until the panel is out of the nip.

i. The displays will show pre-set values, 1-3 digits difference does not give problems and

does not need a pre-set again.

4. The top roller now is pre-set for the mounting job.

5. Prepare mounting as recommended by Seal.

6. Bring panel with prepared print in front of rollers.

7. Start the rotation of rollers in forward mode and push the panel into the nip.

8. When the mounting is finished, stop rotation of rollers.

Setting nip opening and pre-pressure when processing laminates

1. Set pre-pressure to 0.70 N/mm, it is recommended to turn the knob clockwise to set the pre-

pressure.

2. Rotate the hand wheel clockwise to move the roller down until the pressure display value

increases over 0.70 N/mm.

3. The recommended pressure for laminates is 1.10 N/mm to 1.20 N/mm.

4. Do not worry about value of the roller height display when processing laminates, the pressure is

the important parameter.
