The space between the two rubbers is adjusted in working state. In stand-by
state, the unbalance of space between the two rubber rollers is produced by the screw
pitch of the stroke adjustment structure, which does not affect normal operation. If
the quality of lamination is affected, check and adjust according to the following steps:
·
Open the right and left cabinet covers;
·
Check if the left and right pressure adjustment pedestals are loosened. If
so, adjust the pressure adjustment pedestals and tighten them;
·
Check to see if the longitudinal bevel gears on both sides are loose. If the
left is loose, open the gear and take down the screw of pressure-regulat-
ing support. Tighten the screw at the gear top with a wrench after tilt
the transverse bevel gear. Then fix the parts in where they were. If the
right longitudinal bevel gear is loose, it is not necessary to dismantle
the transverse bevel gear. The other checking steps are the same as for
the left side.
· How to adjust the space between the two rollers: ( Please see Figure 13 )
1)
Place a piece of photo-printing paper between the two rubber rollers with a moderate
length (150mm narrower on both sides than the film). Turn the pressure-regulating
hand-wheel so that the top roller contacts the paper. Apply slight pressure and observe
with eyes if the space between the rollers on both sides of the photo-printing paper is the
same.
2)
If the space is uneven, dismantle the transverse bevel gear on the left side. Turn the
longitudinal bevel gear until the space becomes even according to the actual space
needed.
3)
Install the left transverse bevel gear and baffle piece, and tighten the screws of all the
parts.
