Setting the pressure on the main (lamination) rollers
The pressure of the main rollers is factory-set and it is universal for sheets of weight between
135 and 350 g/m2 – the screws at the back side of the equipment are in the working position
when they are at the level of 1.5. For lamination of thinner sheets (115 to 135 g/m2), the
pressure of the rollers may be released slightly (1) so that the rollers do not wrinkle the paper
(position 1 to 1.5). On the contrary, when continuous dark surfaces or uneven paper etc. are
laminated, the pressure of the rollers may be increased slightly (maximally to position 2), on
both sides in the same manner.
When regulating the pressure, it is necessary to regulate evenly on both sides, i.e. it is
necessary to count the revolutions of the regulation screw and check the position of both
pulling elements on the scale. Only when the cutter is used, it is good to have higher pressure
on the side of the perforation.
After completing work with the laminator, release the arm of the pressure from the
regulation screw.
G
Important notice – high pressure of the rollers causes the engine to overload, which
may further cause damage on the electrical circuits of the laminator
The circuits of the engine are protected against overload by the program. If permanent
overload occurs, first the emergency sound signal sounds and a “MOTOR OVERFLOW”
warning appears on the display. Unless the servicing staff decreases the speed of the motion
immediately and significantly, and stops the equipment within 30 seconds, the processor will
stop the equipment after 30 seconds automatically and a warning "MOTOR SYSTEM
OWERFLOW" will appear on the display. The operation may continue after approx. 30
minutes and after the pressure on the rollers is decreased. The sound alarm of overload may
be turned off by pressing any of the buttons. If you wish to complete the lamination without
any losses within the subsequent 30 seconds, do not turn off the sound alarm using the
MOTOR & PAUSE or HEATING & READY buttons.
