Rollers don’t work.
●
No connectivity with power supply
●
Fuse tubes blow
●
Pressure is too high
●
Speed is too slow
●
Motor breaks down
●
Connecting with the power
supply
●
Replace the fuse tubes
●
Reduce the pressures
●
Increase the speed
●
Change motor
The text and drawings
are faint with flake
wrinkles
●
There are dusts on the surface of text
and drawings
●
Inferior quality of the adhesive films
●
Lower temperature
●
Higher speed
●
Clean the surface of text and
drawings
●
Replace adhesive films
●
Increase temperature
●
Reduce speed
The text and drawings
have ruffles and air
bubbles
●
Pressure is too high
●
Temperature is too high
●
Speed is too slow
●
Text and drawings are not even during
the laminating operation
●
Appropriately reduce pressure
●
Lower the temperature
●
Increase speed
●
Improve operational skills
The adhesive films
clearly declines to one
side during laminating
process
●
The pressures on the two sides are not
even
●
The pulls on the two sides are different
when the films are fed into
●
Adjusting the pressures on the
two sides (as to the methods
of adjustment, please refer to
“Examination Methods and
Adjustment for Pressure
Balance of rubber-covered
Roll” )
●
Feeding films again
The quality at the two
sides of the mounted
text and drawings are
different with each
other
●
The pressures on the two sides are not
even
●
Adjusting the pressures on the
two sides (as to the methods
of adjustment, please refer to
“Examination Methods and
Adjustment for Pressure
Balance of Rollers” )
