LAMINATING ROLL HEATING

Each type of laminating film and adhesive have specific temperature range requirements. The required
temperature depends upon the thickness of the paper, line speed, film, humidity, ink coverage, type of
ink, and other factors. Testing of good film adhesion should be done before production occurs. The
laminating temperature range is 210 to 300 °F (100 to 150 °C).

PRESSURE MECHANISM

The pressure mechanism is important for correct adhesion. Depending on the desired final laminating
quality, it may be necessary to change the pressure of the pressure roll against the laminating roll. The
machine manufacturer recommends using a pneumatic pressure ranging from 0.2 to 0.6 MPa. The
pressure is adjusted with regulators I and II.
The pressure can be adjusted separately on the left and right side of the pressure roll.
The pressure roller drops down:
•
20 seconds after pressing the "STOP" button (to stop the machine) on the control panel.
•
Immediately after pressing "emergency button."
•
Immediately after a electricity failure.
